Description

Technical Field

[0001] This invention relates to the field of automotive luggage compartment hook assembly technology, and in particular to an automated installation device for luggage compartment hooks. Background Technology

[0002] like Figures 1 to 2 As shown, a car trunk hook 6 in the prior art includes a base 61, a frame 62, and a hook 63. The base 61 is made of galvanized steel and has a U-shaped structure with a locking hole 614 at the bottom. The base 61 forms a mounting groove 611 for mounting the frame 62 along its length. The end of the base 61 is integrally bent to form a locking foot 612. The two sides of the base 61 near the locking foot 612 are bent to form locking parts 613. The end of the frame 62 has a locking groove 621 corresponding to the locking part 613. Currently, the factory uses manual assembly. Assembly requires first inserting the frame 62 into the mounting groove 611 of the base 61, and then pushing the frame 62 to move it horizontally towards the locking foot 612 in the mounting groove 611, so that the locking part 613 and the locking groove 621 lock together. The frame 62 has a rotating positioning part 622 for rotating and mounting a torsion spring 65, so that the torsion spring 65 is in a preset torsional posture. Insert the rotating positioning part 622, and make one pin of the torsion spring 65 pass through the frame 62 and lock into the locking hole 614 on the base 61 to achieve pre-tight positioning of the torsion spring 65, ensuring that the support feet at both ends of the torsion spring 65 avoid each other from the rotating positioning part 622. Then, use the pin 64 to connect the base 61, the frame 62, the hook 63 and the torsion spring 65, so that the end of the hook 63 is rotatably connected to the frame 62. Finally, weld the end of the pin 64 to the base 61 to fix it. The pin 64 not only acts as a hinge between the hook 63 and the frame 62, but also as a fastener between the frame 62 and the base 61. The torsion spring 65 has an elastic restoring force to drive the hook 63 to keep the frame 62 closed. When using it, you only need to overcome the elastic force of the torsion spring 65 and flip the hook 63 relative to the frame 62 to hang and pick up items. However, the manual assembly is not accurate enough and the assembly efficiency is not high enough, which needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to provide an automated installation device for luggage compartment hooks, which improves the assembly accuracy and efficiency of products and facilitates continuous industrial production.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automated installation device for luggage compartment hooks, including a turntable mechanism and a feeding system, wherein the turntable mechanism includes a drive structure, an outer moving plate and an inner fixed plate, and the drive structure drives the outer moving plate to rotate concentrically relative to the inner fixed plate. The sidewall of the inner fixed plate includes concentrically distributed outer and inner circular arc segments connected end to end, and the radius of the outer circular arc segment is greater than the radius of the inner circular arc segment. The feeding system includes a base feeding mechanism, a frame feeding mechanism, a hook torsion spring feeding mechanism, a pin loading mechanism, a welding mechanism, and a unloading mechanism arranged sequentially along the circumference of the turntable mechanism. The base feeding mechanism, the frame feeding mechanism, and the unloading mechanism correspond to the inner arc segment, and the hook torsion spring feeding mechanism, the pin loading mechanism, and the welding mechanism correspond to the outer arc segment. The outer movable plate is provided with several clamping units. Each clamping unit includes a fixed seat for positioning the base, a sliding seat slidably disposed on the fixed seat, a pushing component connected to one end of the sliding seat near the inner fixed plate, and a clamping component disposed between the sliding seat and the fixed seat. The fixed seat is fixed on the outer movable plate. A spring is provided between the pushing component and the fixed seat. The spring has an elastic force that pushes the pushing component against the side wall of the inner fixed plate. When the clamping unit corresponds to the frame feeding mechanism and the pushing component abuts against the inner arc segment, the sliding seat is in the first position relative to the fixed seat, and the clamping component is in the released state. As the outer moving plate rotates relative to the inner fixed plate, the pushing component rotates from the inner arc segment to the outer arc segment. During this process, the pushing component pushes the sliding seat relative to the fixed seat from the first position to the second position, causing the base's clamping part to engage in the frame's clamping groove. The clamping component moves from the released state to the clamping state and clamps the base.

[0005] By adopting the above technical solution, during equipment operation, the base feeding mechanism feeds the base onto the corresponding clamping unit on the outer moving plate, and uses the fixed seat to position the base. At this time, the spring drives the pushing component to abut against the inner arc segment, the sliding seat is in the first position relative to the fixed seat, and the clamping component is in the released state. Then, the drive structure drives the outer moving plate to rotate relative to the inner fixed plate, causing the clamping unit with the base to rotate to the frame feeding mechanism. At this time, the pushing component is still abutting against the inner arc segment, and the frame feeding mechanism feeds the frame onto the sliding unit of the clamping unit. The frame is moved to the next position, and the clamping part of the frame avoids the clamping groove of the base. Then, the outer moving plate continues to rotate relative to the inner fixed plate to the next station, so that the clamping unit rotates from the frame feeding mechanism to the hook torsion spring feeding mechanism. During the rotation, the pushing component gradually slides from the inner arc segment to the outer arc segment, and pushes the sliding seat relative to the fixed seat from the first position to the second position, so that the clamping part of the base is engaged in the clamping groove of the frame, and the clamping component switches from the released state to the clamping state and clamps the base. When the clamping unit just rotates to the hook torsion spring... After the material feeding mechanism, the hook torsion spring feeding mechanism first places the torsion spring on the rotating positioning part of the frame in a specific posture, so that one pin of the torsion spring just passes through the frame and inserts into the corresponding clamping hole on the base. Then, the hook torsion spring feeding mechanism places the hook on the frame. After that, the drive structure drives the outer moving plate to rotate relative to the inner fixed plate, so that the clamping unit rotates to the pin assembly mechanism for pin assembly. Then, the drive structure drives the corresponding clamping unit to rotate to the welding mechanism, which welds and fixes the pin end to the base, completing the automatic assembly of the car trunk hook. Finally, the clamping unit with the assembled product rotates to the unloading mechanism. During this process, the spring pushes the pushing component to gradually slide from the outer arc segment to the inner arc segment, so that the sliding seat moves from the second position to the first position relative to the fixed seat, and the clamping component switches from the clamping state to the release state and releases the base. Then, the unloading mechanism unloads the assembled product. This cycle is repeated to complete the industrial automatic assembly of the car trunk hook, which has the effect of improving the assembly accuracy and efficiency of the product and facilitating continuous industrial production.

[0006] A further feature of the present invention is that the two ends of the outer arc segment are connected to the two ends of the inner arc segment through an arc-shaped guide segment, and the sector angle α of the inner arc segment is between 120-180°, and the sector angle β of the outer arc segment is between 140-200°.

[0007] By adopting the above technical solution, the arc-shaped guide section serves as a continuous curvature transition zone between the inner and outer arc sections. This avoids the instantaneous force change caused by rigid inflection points when the pushing component moves between the inner and outer arc sections, reduces the impact load on the spring and sliding seat, extends the life of key components, and improves the stability of equipment operation. Furthermore, the sector angle β of the outer arc section is greater than that of the inner arc section α, ensuring the rational layout of the three stations for base loading, frame loading, and unloading on the circumference. This avoids mechanical interference caused by insufficient spacing between corresponding stations due to the sector angle of the outer arc section being too small, thus achieving a balance between space utilization and motion efficiency.

[0008] A further configuration of the present invention is as follows: the pushing assembly includes a wheel seat, a roller and a connecting rod, the roller is rotatably disposed at a first end of the wheel seat, the connecting rod is fixedly connected to a second end of the wheel seat, the spring is sleeved on the connecting rod, and one end of the spring abuts against the fixed seat, and the other end of the spring abuts against the wheel seat.

[0009] By adopting the above technical solution, the roller is rotated and installed at the end of the wheel seat, which transforms the traditional sliding friction into rolling friction, greatly reducing motion resistance and heat generation, improving the response speed and life of the mechanism. When the roller contacts the outer arc segment or the inner arc segment, the spring can automatically compress or rebound, and the thrust can be dynamically adjusted without external driving force, ensuring that the roller is always in close contact with the side wall of the inner fixed plate.

[0010] A further configuration of the present invention is as follows: the fixed base is provided with a first stop rib and a second stop rib at both ends; the sliding base in the first position is limited and stopped by the first stop rib; the sliding base in the second position is limited and stopped by the second stop rib; and the first stop rib is provided with a clearance hole corresponding to the connecting rod, and the connecting rod is movably passed through the clearance hole and the first stop rib.

[0011] By adopting the above technical solution, when the sliding seat moves on the fixed seat, the first stop rib and the second stop rib constitute the two end limit boundaries of the sliding seat, so that the sliding seat can only move within the preset stroke between the first position and the second position. This helps to eliminate the positioning deviation caused by spring rebound overshoot or component inertial slippage, and ensures the repeatability accuracy of clamping force and locking engagement each time.

[0012] A further feature of the present invention is that the fixed base has a protruding positioning block, the top of the positioning block has a positioning groove, and the base's locking foot is inserted into the positioning groove for positioning.

[0013] By adopting the above technical solution, the base feeding mechanism can achieve precise positioning of the base on the fixed seat by relying on the interlocking cooperation between the clamping foot and the positioning groove during the base feeding assembly, thereby improving the assembly accuracy of the product.

[0014] A further feature of the present invention is that: a material groove is provided in the middle of the sliding seat along the sliding direction, and a straight groove communicating with the material groove is provided at the bottom of the sliding seat. The straight groove extends in the same direction as the material groove. When the sliding seat slides between a first position and a second position relative to the fixed seat, the positioning block guides and cooperates with the straight groove.

[0015] By adopting the above technical solution, when the sliding seat slides between the first position and the second position, the guiding effect of the positioning block and the straight groove is used to improve the consistency of the sliding direction of the sliding seat relative to the fixed seat.

[0016] A further configuration of the present invention is as follows: the clamping assembly includes two clamping blocks arranged opposite to each other; the sliding seat has guide grooves opened opposite to each other on both sides of the material trough; the guide grooves on both sides are connected to the material trough, and the extending direction of the guide grooves is perpendicular to the extending direction of the material trough; the clamping blocks are slidably disposed in the corresponding guide grooves; the clamping blocks are fixedly provided with guide posts; the fixed seat has figure-eight shaped trajectory grooves opened on both sides; the guide posts constrain and slidably disposed in the corresponding trajectory grooves, and drive the clamping blocks on both sides to move closer or further apart.

[0017] By adopting the above technical solution, the geometric cooperation between the "eight"-shaped trajectory groove and the guide column automatically transforms the linear displacement of the sliding seat into the equidistant symmetrical convergent or divergent motion of the clamping blocks on both sides, thereby realizing the clamping and release of the base by the clamping component. In addition, the symmetrical geometric characteristics of the "eight"-shaped trajectory force the clamping blocks on both sides to move synchronously along the central axis, ensuring that the clamping force always acts on the geometric center of the base, effectively avoiding the clamping offset caused by asynchronous control in traditional dual independent clamping mechanisms, which is conducive to improving the assembly accuracy of the product.

[0018] A further feature of the present invention is that: the sliding seat has strip-shaped holes on both sides corresponding to the guide post, the strip-shaped holes are connected to the guide groove, and the extension direction of the strip-shaped holes and the guide groove are the same, and the end of the guide post passes through the strip-shaped hole and is guided and engaged with the track groove.

[0019] By adopting the above technical solution, the strip hole can guide and constrain the movement trajectory of the guide post. Combined with the guiding force between the guide groove and the clamping block, the consistency of the lateral sliding direction of the clamping block relative to the sliding seat is improved through dual guidance.

[0020] A further feature of the present invention is that the side wall of the sliding seat is independently provided with a welding groove and a pin hole, the welding groove and the pin hole are distributed opposite to each other and communicate with the material groove, the pin loading mechanism includes a pin feeding strip, a multi-axis mechanical claw and a pusher cylinder, the output end of the pusher cylinder is provided with a push rod, the multi-axis mechanical claw is used to clamp the pin from the pin feeding strip to the pin hole, and the pusher cylinder drives the push rod to push the pin into the pin hole.

[0021] A further configuration of the present invention is as follows: the drive structure includes a geared motor module and a drive gear disposed at the output end of the geared motor module; a fixed column is coaxially fixed at the center of the inner fixed plate; a driven gear is integrally disposed at the bottom of the outer moving plate; a through hole is opened in the middle of the outer moving plate and the driven gear; the fixed column is rotatably disposed through the through hole; and the drive gear meshes with the driven gear.

[0022] By adopting the above technical solution, the drive gear and driven gear mesh directly, resulting in a short transmission path and high rigidity. Combined with the integrated molding design of the driven gear and the outer moving plate, the defects of fit clearance and keyway loosening in the traditional split structure are eliminated, improving the rotational accuracy of the outer moving plate. In addition, the fixed column is fixedly connected to the inner fixed plate, serving as the only rotational reference axis. It passes through the through hole of the outer moving plate and the driven gear, enabling the entire rotating system to move around the same axis, effectively improving the rotational concentricity of the outer moving plate relative to the inner fixed plate.

[0023] In summary, the present invention has the following beneficial effects: The system employs a concentrically rotating inner fixed plate and an outer moving plate to achieve station cycle. Multiple clamping units are arranged on the outer moving plate. Each unit includes a fixed base, a sliding base, a pushing assembly, and a clamping assembly. After the base is placed onto the fixed base by the feeding mechanism, the pushing assembly, under the action of a spring, engages with the inner arc segment. The sliding base is in the released position, the clamping assembly is released, and the turntable rotates to the frame feeding station. The frame is precisely placed on the sliding base. At this point, the clamping part still avoids the base groove. As rotation continues, the pushing assembly slides along the inner arc to the outer arc segment with a larger radius, thus pushing the sliding base from the first position to the second position, causing the frame clamping part to automatically... The base is embedded in the slot, and the clamping components close simultaneously to firmly clamp the base. Then, the torsion spring is precisely placed in the rotating part of the frame, with one end inserted into the base clamping hole. The hook is then installed, and the machine moves to the pin assembly station. The pin is gripped by the mechanical claw, pushed into the pin hole by the cylinder, and the welding mechanism then welds the end of the pin. Finally, the machine moves to the unloading station, and the pushing component slides back to the inner arc along the outer arc. The spring resets, causing the sliding seat to retract, and the clamping components automatically release. The assembled product is then removed. The entire process relies on the arc contour and the spring to achieve mechanical linkage. No manual intervention is required throughout the process. The assembly accuracy is high, the cycle time is stable, and it is suitable for continuous industrial production. Attached Figure Description

[0037] The invention will now be further described with reference to the accompanying drawings.

[0038] An automated installation device for luggage compartment hooks, such as Figures 3 to 10As shown, the device includes a turntable mechanism and a feeding system. The turntable mechanism includes a drive structure 1, an outer moving plate 2, and an inner fixed plate 3. The drive structure 1 drives the outer moving plate 2 to rotate concentrically relative to the inner fixed plate 3. The sidewall of the inner fixed plate 3 includes concentrically distributed outer arc segments 31 and inner arc segments 32 connected end to end, and the radius of the outer arc segment 31 is larger than the radius of the inner arc segment 32. The feeding system includes a base feeding mechanism 41, a frame feeding mechanism 42, and a hanging mechanism arranged sequentially along the circumference of the turntable mechanism. The system includes a hook torsion spring feeding mechanism 43, a pin mounting mechanism 44, a welding mechanism 45, and a unloading mechanism 46. The base feeding mechanism 41, the frame feeding mechanism 42, and the unloading mechanism 46 correspond to the inner arc segment 32, while the hook torsion spring feeding mechanism 43, the pin mounting mechanism 44, and the welding mechanism 45 correspond to the outer arc segment 31. The outer moving plate 2 is equipped with six clamping units 5. Each clamping unit 5 includes a fixed seat 51 for positioning the base 61 and a sliding seat 5 slidably mounted on the fixed seat 51. 2. A pushing assembly 53 connected to one end of the sliding seat 52 near the inner fixed plate 3; a clamping assembly disposed between the sliding seat 52 and the fixed seat 51; the fixed seat 51 is fixed to the outer moving plate 2; a spring 55 is provided between the pushing assembly 53 and the fixed seat 51; the spring 55 has an elastic force to push the pushing assembly 53 against the side wall of the inner fixed plate 3; when the clamping unit 5 corresponds to the frame feeding mechanism 42, and the pushing assembly 53 abuts against the inner arc segment 32, the sliding seat 52 relative to... The fixed base 51 is in the first position and the clamping component is in the released state. When the outer moving plate 2 rotates relative to the inner fixed plate 3, the pushing component 53 rotates from the inner arc segment 32 to the outer arc segment 31. During this process, the pushing component 53 pushes the sliding base 52 relative to the fixed base 51 from the first position to the second position, so that the clamping part 613 of the base 61 is engaged in the clamping groove 621 of the frame 62, and the clamping component moves from the released state to the clamping state and clamps the base 61.

[0039] like Figures 6 to 7As shown, the two ends of the outer arc segment 31 are connected to the two ends of the inner arc segment 32 through the arc-shaped guide segment 33, and the sector angle α of the inner arc segment 32 is between 120-180°, and the sector angle β of the outer arc segment 31 is between 140-200°. In this embodiment, the sector angle α of the inner arc segment 32 and the sector angle β of the outer arc segment 31 are both set to 170°; the drive structure 1 includes a geared motor module 11, and a drive structure 1 is provided in the geared motor module 11. The drive gear 12 at the output end has a fixed post 30 coaxially fixed at the center of the inner fixed plate 3. The driven gear 21 is integrally provided at the bottom of the outer moving plate 2. A through hole is opened in the middle of the outer moving plate 2 and the driven gear 21. The fixed post 30 rotates through the through hole. The drive gear 12 meshes with the driven gear 21. The drive gear 12 and the driven gear 21 mesh directly, resulting in a short transmission path and high rigidity. Combined with the integral molding design of the driven gear 21 and the outer moving plate 2, it eliminates the traditional split design. The defects of fit clearance and keyway looseness in the structure improve the rotation accuracy of the outer moving plate 2. In addition, the fixed column 30 is fixedly connected to the inner fixed plate 3, serving as the only rotation reference axis. It passes through the through hole of the outer moving plate 2 and the driven gear 21, so that the entire rotation system moves around the same axis, effectively improving the rotational concentricity of the outer moving plate 2 relative to the inner fixed plate 3. The bottom of the outer moving plate 2 is equipped with six position sensors 22. When the outer moving plate 2 drives the clamping unit 5 to rotate relative to the inner fixed plate to a predetermined position, the position sensors 22 are used to detect the position and feed back to the drive structure 1 for intermittent operation, thereby ensuring the normal operation of the entire equipment. The six clamping units 5 are equally spaced on the outer moving plate 2 along the circumference of the inner fixed plate 3. The included angle between the central axes of adjacent clamping units 5 is 60°, so that the number of clamping units 5 corresponds to the number of workstations and is evenly distributed along the circumference of the outer moving plate 2, ensuring that each workstation corresponds to the stopping position of one clamping unit 5.

[0040] like Figures 7 to 12As shown, the pushing assembly 53 includes a wheel seat 531, a roller 532, and a connecting rod 533. The roller 532 is rotatably mounted on the first end of the wheel seat 531, and the connecting rod 533 is fixedly connected to the second end of the wheel seat 531. A spring 55 is sleeved on the connecting rod 533, with one end of the spring 55 abutting against the fixed seat 51 and the other end abutting against the wheel seat 531. The roller 532 is rotatably mounted on the end of the wheel seat 531, converting traditional sliding friction into rolling friction, significantly reducing motion resistance and heat generation, and improving the mechanism's response speed and lifespan. When the roller 532 contacts the outer arc segment 31 or the inner arc segment 32, the spring 55 can automatically compress or rebound, achieving dynamic adjustment of the pushing force without external driving force, ensuring that the roller 532 is always in close contact with the side wall of the inner fixed plate 3. The fixed seat 51 has a first stop 511 and a second stop 512 at both ends. The sliding seat 52 in the first position is limited and stopped by the first stop 511, and the sliding seat 52 in the second position is limited and stopped by the second stop 512. The first stop 511 has a clearance hole 5111 corresponding to the connecting rod 533. The connecting rod 533 passes through the clearance hole 5111 and moves through the first stop 511. When the sliding seat 52 moves on the fixed seat 51, the first stop 511 and the second stop 512 form the two end limit boundaries of the sliding seat 52, so that the sliding seat 52 can only move within a preset stroke between the first position and the second position. This helps to eliminate the positioning deviation caused by the spring 55 rebound overshoot or the inertial slippage of the component, and ensures the repeatability accuracy of the clamping force and clamping engagement each time.

[0041] like Figures 8 to 12 As shown, where Figure 8 This is the present invention. Figure 7 A magnified view of a portion of region C shows the sliding seat 52 in the first position relative to the fixed seat 51, with the clamping assembly in the released state. Figure 9 This is the present invention. Figure 7 A magnified view of a portion of region D shows the sliding seat 52 in the first position relative to the fixed seat 51, with the clamping assembly in the released state. Figure 10 This is the present invention. Figure 7A partial enlarged view of area E shows the sliding seat 52 in its second position relative to the fixed seat 51, with the clamping assembly in a clamping state. The fixed seat 51 has a protruding positioning block 513, with a positioning groove 5131 on its top. The base 61's locking feet 612 engage with the positioning groove 5131 for positioning, allowing the base loading mechanism 41 to accurately position the base 61 on the fixed seat 51 during assembly, thus improving product assembly accuracy. The sliding seat 52 has a material groove 521 in its middle along the sliding direction, and a straight groove 522 connecting the material groove 521 is located at its bottom. The straight groove 522 extends in the same direction as the material trough 521. When the sliding seat 52 slides between the first and second positions relative to the fixed seat 51, the positioning block 513 guides and cooperates with the straight groove 522. When the sliding seat 52 slides between the first and second positions, the guiding effect of the positioning block 513 and the straight groove 522 improves the consistency of the sliding direction of the sliding seat 52 relative to the fixed seat 51. The clamping assembly includes two clamping blocks 54 arranged opposite to each other. The sliding seat 52 has guide grooves 523 on both sides of the material trough 521. The guide grooves 523 on both sides are connected to the material trough 521, and the extending direction of the guide grooves 523 is perpendicular to the extending direction of the material trough 521. The clamping block 54 is slidably disposed in the corresponding guide groove 523. The clamping block 54 is fixedly provided with a guide post 541. The fixed base 51 has "eight"-shaped trajectory grooves 514 on both sides. The guide post 541 constrains and slides in the corresponding trajectory groove 514, and drives the clamping blocks 54 on both sides to move closer or further apart. The geometric cooperation between the "eight"-shaped trajectory groove 514 and the guide post 541 automatically converts the linear displacement of the sliding base 52 into the equidistant symmetrical convergent or divergent motion of the clamping blocks 54 on both sides, thereby realizing the clamping and release of the clamping assembly on the base 61. In addition, the symmetrical geometric characteristics of the "eight"-shaped trajectory force the clamping blocks 54 on both sides to move synchronously along the central axis, ensuring that the clamping force always acts on the base. The geometric center of seat 61 effectively avoids clamping offset caused by asynchronous control in traditional dual independent clamping mechanisms, which is beneficial to improving the assembly accuracy of the product. The sliding seat 52 has strip holes 524 on both sides corresponding to the guide posts 541. The strip holes 524 are connected to the guide grooves 523, and the extension directions of the strip holes 524 and the guide grooves 523 are the same. The ends of the guide posts 541 pass through the strip holes 524 and are guided and engaged with the track grooves 514. The strip holes 524 can guide and constrain the movement trajectory of the guide posts 541. With the guiding force between the guide grooves 523 and the clamping blocks 54, the consistency of the lateral sliding direction of the clamping blocks 54 relative to the sliding seat 52 is improved through double guidance.

[0042] like Figures 3 to 5 and Figures 11 to 12As shown, in this embodiment, the side wall of the sliding seat 52 is independently provided with a welding groove 525 and a pin hole 526. The welding groove 525 and the pin hole 526 are distributed opposite to each other and communicate with the material tank 521. The pin loading mechanism 44 includes a pin feeding belt 441, a multi-axis mechanical claw 442 and a pushing cylinder 443. The output end of the pushing cylinder 443 is provided with a push rod 4431.

[0043] The basic working principle of this invention is as follows: An outer movable disk 2 is concentrically and rotatably arranged outside the inner fixed disk 3. The driving structure 1 drives the outer movable disk 2 to rotate concentrically relative to the inner fixed disk 3. The sidewall of the inner fixed disk 3 includes an outer arc segment 31 and an inner arc segment 32 that are concentrically distributed and connected end to end. The radius of the outer arc segment 31 is larger than the radius of the inner arc segment 32. The outer movable disk 2 is provided with several clamping units 5. The clamping unit 5 includes a fixed seat 51 for positioning the base 61, a sliding seat 52 slidably disposed on the fixed seat 51, a pushing component 53 connected to the sliding seat 52 near the inner fixed disk 3, and a clamping component disposed between the sliding seat 52 and the fixed seat 51. When the equipment is running, the base feeding mechanism 41 feeds the base 61 onto the corresponding clamping unit 5 on the outer movable disk 2, and utilizes... The fixed seat 51 positions the base 61. At this time, the spring 55 drives the pushing component 53 to abut against the inner arc segment 32. The sliding seat 52 is in the first position relative to the fixed seat 51, and the clamping component is in the released state. Then, the driving structure 1 drives the outer moving plate 2 to rotate relative to the inner fixed plate 3, so that the clamping unit 5 with the base 61 is rotated to the frame feeding mechanism 42. At this time, the pushing component 53 is still abutting against the inner arc segment 32. The frame feeding mechanism 42 feeds the frame 62 onto the sliding seat 52 of the clamping unit, and makes the clamping part 613 of the frame 62 and the clamping groove 621 of the base 61 avoid each other. Then, the outer moving plate 2 continues to rotate relative to the inner fixed plate 3 to the next station, so that the clamping unit 5 rotates from the frame feeding mechanism 42 to the hook torsion spring feeding mechanism 43. During rotation, the pushing component 53 gradually slides from the inner arc segment 32 to the outer arc segment 31, and pushes the sliding seat 52 relative to the fixed seat 51 from the first position to the second position, so that the clamping part 613 of the base 61 is engaged in the clamping groove 621 of the frame 62, and the clamping component switches from the released state to the clamping state and clamps the base 61. When the clamping unit 5 rotates to the hook torsion spring feeding mechanism 43, the hook torsion spring feeding mechanism 43 first places the torsion spring 65 in a specific posture on the rotating positioning part 622 of the frame 62, so that one pin of the torsion spring 65 just passes through the frame 62 and inserts into the corresponding clamping hole 614 on the base 61. Then, the hook torsion spring feeding mechanism 43 places the hook 63 on the frame 62, and then the drive structure 1. Drive structure 1 drives the outer moving plate 2 to rotate relative to the inner fixed plate 3, causing the clamping unit 5 to rotate to the pin mounting mechanism 44 for pin shaft 64 assembly. Then, drive structure 1 drives the corresponding clamping unit 5 to rotate to the welding mechanism 45, which welds and fixes the end of the pin shaft 64 to the base 61, completing the automatic assembly of the car trunk hook 6. Finally, the clamping unit 5 with the assembled product rotates to the unloading mechanism 46. During this process, spring 55 pushes the pushing component 53 to gradually slide from the outer arc segment 31 to the inner arc segment 32, causing the sliding seat 52 to move from the second position to the first position relative to the fixed seat 51, and causing the clamping component to switch from the clamping state to the release state and release the base 61. Then, the unloading mechanism 46 unloads the assembled product, and the cycle continues.The automated industrial assembly of the car trunk hook 6 improves assembly accuracy and efficiency, and facilitates continuous industrial production.
