Description

Technical Field

[0001] This utility model belongs to the field of automated assembly equipment, and in particular relates to an assembly machine for automotive knob adjustment seats. Background Technology

[0002] Automotive knob adjustment seats are key base components used to install and support rotary switches. Currently, the production and assembly process of these adjustment seats still heavily relies on manual operation or a semi-automatic production line with manual assistance. In purely manual assembly, workers need to manually complete steps such as picking up, aligning, and pressing various parts, which is inefficient and the consistency and assembly accuracy of products are greatly affected by the individual operator's skill level, making it difficult to guarantee the quality stability of large-scale production. Even in semi-automatic production lines that have introduced some automation equipment, their core bottlenecks are becoming increasingly prominent: the design of the conveyor structure in the production line has significant flaws, making it difficult to achieve accurate and reliable material transfer between workstations. Specifically, when transferring the adjustment seat base or semi-finished product that has been initially processed at one workstation to the next workstation, conventional conveyor mechanisms such as conveyor belts often experience problems such as inaccurate positioning, incomplete transfer, jamming, or posture deviation. This uncertainty in conveying directly causes the automated assembly unit to be unable to accurately grasp or perform the next operation, thus seriously affecting the accuracy and quality of the final assembly. To ensure the operation of the production line and the achievement of product quality standards, companies have to rely heavily on manual labor for frequent adjustments to the position of workpieces or troubleshooting of jamming problems. This continuous human intervention not only keeps labor costs a high proportion of total production costs, limiting the scope for cost optimization, but also seriously hinders the improvement of overall production efficiency, becoming a major obstacle to achieving efficient, low-cost, and high-quality automated production in this sub-sector. Summary of the Invention

[0003] Based on the aforementioned problems in the existing technology, this utility model provides an automotive knob adjustment seat assembly machine, including a frame, on which a slide rail assembly and a moving assembly are fixedly installed. The slide rail assembly is provided with a slide groove that matches and slides with the adjustment seat. The upper surface of one side wall of the slide groove is lower than the upper surface of the adjustment seat, and this side is defined as the actuating side. The slide groove is provided with three stations, which are equally spaced. The three stations are sequentially installed or connected with a rotation orientation assembly, a screw mounting assembly, and an elastic snap-fit ​​mounting assembly. The moving assembly is located on one side of the actuating side and is provided with a lever plate that can extend from the actuating side to the top of the slide groove. The lever plate is sequentially provided with three slots that match the adjustment seat. The three slots are equally spaced and correspond to the three stations respectively. The moving assembly also includes a material-feeding cylinder that drives the lever plate to move along the extension direction of the slide groove.

[0004] The slide rail assembly includes a slide rail base, the slide groove is disposed on the upper surface of the slide rail base, the slide rail base is provided with a push port at one end of the slide groove, the slide rail base is provided with a feed port communicating with the slide groove on one side of the push port, the feed port and the push port are perpendicular to each other, the feed port is connected to the discharge end of the adjusting seat feeding assembly, the slide rail base is provided with a discharge port at the other end of the slide groove, and the slide rail base is equipped with a push component at the push port for pushing the adjusting seat from the feed port to the first station.

[0005] The material pushing assembly includes a material pushing cylinder, a connecting plate, and a material pushing block. The material pushing cylinder is fixedly installed on the slide base. The telescopic rod of the material pushing cylinder is fixedly connected to the connecting plate. The material pushing block is fixedly connected to the connecting plate and slidably installed at the material pushing port. The material pushing cylinder drives the material pushing block to slide in the slide groove through the transmission of the telescopic rod and the connecting plate. The connecting plate also has a buffer damper fixedly installed on the side near the slide base.

[0006] The slide base has a material distribution cylinder fixedly installed at the bottom of the discharge port. The extension direction of the extension rod of the material distribution cylinder is perpendicular to the extension direction of the slide. The extension rod of the material distribution cylinder is fixedly installed with a material distribution trough. The material distribution trough is provided with two parallel discharge channels. One end of each discharge channel faces the slide, and one of the discharge channels is connected to the slide. The other end of each discharge channel is connected to a receiving box. The material distribution cylinder drives the material distribution trough to move and switch the discharge channel connected to the slide.

[0007] The slide base has two limiting cylinders on one side of the slide groove. The telescopic rods of the two limiting cylinders extend into the slide groove and act as limiting rods. One limiting rod is located on one side of the feed inlet and cooperates with the pushing component to limit the adjusting seat at the feed inlet. The other limiting rod is located on one side of the station corresponding to the rotary orientation component and cooperates with the pushing component to limit the adjusting seat at that station.

[0008] The movable component includes a mounting base, on which a clamping cylinder is fixedly mounted. A movable seat is fixedly mounted on the telescopic rod of the clamping cylinder.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] As attached Figure 1-6 The illustrated automotive knob adjustment seat assembly machine includes a frame 1. A slide rail assembly 2, a moving assembly 3, an adjustment seat feeding assembly 4, a rotation orientation assembly 5, a screw mounting assembly 6, and a spring-loaded buckle mounting assembly 7 are fixedly mounted on the frame 1. The slide rail assembly 2 includes a slide rail base 8 fixedly mounted on the frame 1. The upper surface of the slide rail base 8 is provided with a slide groove 9 that slides and matches the adjustment seat a. The upper surface of one side wall of the slide groove 9 is lower than the upper surface of the adjustment seat a; this side is defined as the actuating side. The height of the other side wall of the slide groove 9 is not limited; it can be higher or lower than the upper surface of the adjustment seat a, but its height must be able to cooperate with the actuating side to form the slide groove 9, so as to achieve the purpose of conveying the adjustment seat a.

[0019] The slide base 8 has a push port at one end of the slide groove 9, and an inlet communicating with the slide groove 9 is provided on one side of the push port. The inlet and push port are perpendicular. The slide base 8 has an outlet at the other end of the slide groove 9. The adjusting seat feeding assembly 4, the rotary orientation assembly 5, the screw mounting assembly 6, and the elastic buckle mounting assembly 7 are arranged and fixedly installed on both sides of the slide base 8 in sequence from the push port to the outlet along the extension direction of the slide groove 9. The adjusting seat feeding assembly 4 and the rotary orientation assembly 5 are located on one side of the actuation side, and the screw mounting assembly 6 and the elastic buckle mounting assembly 7 are located on the other side of the slide base 8. The adjusting seat feeding assembly 4, the rotary orientation assembly 5, the screw mounting assembly 6, and the elastic buckle mounting assembly 7 are all conventional structures used in existing semi-automatic production lines. The adjusting seat feeding assembly 4, the screw mounting assembly 6, and the elastic buckle mounting assembly 7 all use a conventional vibrating feeding plate to feed the slide groove 9, respectively conveying the adjusting seat a, screws, and elastic buckles to the slide groove 9. The actuators of the screw mounting assembly 6 and the elastic snap-fit ​​mounting assembly 7, as well as the rotary orientation assembly 5, all employ several cylinders to drive the end effector (such as an electric screwdriver, finger cylinder, etc.) to move vertically and laterally, thereby moving the end effector closer to or further away from the chute 9 and performing corresponding processing on the workpiece. The chute 9 has three stations arranged sequentially between the inlet and outlet, with equal intervals between the three stations. The rotary orientation assembly 5 is fixedly installed at the first station from the inlet to the outlet. The actuator of the screw mounting assembly 6 is installed at the second station and cooperates with the vibrating feed plate of the screw mounting assembly 6. The actuator of the elastic snap-fit ​​mounting assembly 7 is installed at the third station and cooperates with the vibrating feed plate of the elastic snap-fit ​​mounting assembly 7. The inlet of the chute 9 is connected to the outlet of the adjusting seat feeding assembly 4, meaning the vibrating discharge channel of the adjusting seat feeding assembly 4 is directly connected to the chute 9, allowing the adjusting seat a to enter the chute 9.

[0020] The slide base 8 is equipped with a pushing assembly at the pushing port for pushing the adjusting seat a from the feed port to the first working position. The pushing assembly includes a pushing cylinder 10, a connecting plate 11, and a pushing block 12. The pushing cylinder 10 is fixedly installed on the slide base 8. The extension direction of the telescopic rod of the pushing cylinder 10 is parallel to the extension direction of the slide groove 9 and is fixedly connected to the connecting plate 11. The pushing block 12 is fixedly connected to the connecting plate 11 and slidably installed at the pushing port. The pushing cylinder 10 drives the pushing block 12 to slide in the slide groove 9 through the transmission of the telescopic rod and the connecting plate 11. A buffer damper 13 is also fixedly installed on the side of the connecting plate 11 near the slide base 8. When the adjusting seat a enters the slide groove 9 from the feed port, the pushing cylinder 10 drives the pushing block 12 to push the adjusting seat a to the first working position. A material distribution cylinder 14 is fixedly installed at the bottom of the discharge port of the slide base 8. The extension direction of the extension rod of the material distribution cylinder 14 is perpendicular to the extension direction of the slide 9. A material distribution trough 15 is fixedly installed on the extension rod of the material distribution cylinder 14. The material distribution trough 15 is provided with two parallel discharge channels 16. One end of each discharge channel 16 faces the slide 9 and one of the discharge channels 16 is connected to the slide 9. The other end of each of the two discharge channels 16 is connected to a receiving box 17. The material distribution cylinder 14 drives the material distribution trough 15 to move and switch the discharge channel 16 connected to the slide 9. Depending on actual needs, different functions can be achieved through the cooperation of the dispensing cylinder 14 and the dispensing trough 15. For example, a detection mechanism 18 can be set on one side of the discharge port of the chute 9. The detection mechanism 18 and the dispensing cylinder 14 are connected in communication or controlled by a unified electrical control system. The two receiving boxes 17 serve as the receiving box for qualified products and the receiving box for unqualified products, respectively. Under normal circumstances, the dispensing trough 15 connects the chute 9 and the receiving box for qualified products. When the detection mechanism 18 detects the presence of unqualified products, the dispensing cylinder 14 is activated and drives the dispensing trough 15 to move, changing the connection between the chute 9 and the receiving box for unqualified products. Alternatively, when one of the receiving boxes 17 is full, the dispensing cylinder 14 is activated and drives the dispensing trough 15 to move, using the other receiving box 17 to receive products. Then, a third empty receiving box is used to replace the receiving box 17 that is already full of products, allowing the assembly machine to run continuously without stopping to replace the receiving boxes 17. The slide base 8 has two limiting cylinders 19 on one side of the slide groove 9. The telescopic rods of the two limiting cylinders 19 extend into the slide groove 9 and act as limiting rods. One limiting rod is located on the side of the feed inlet and cooperates with the pushing component to limit the adjusting seat a at the feed inlet, which can prevent the feeding of the adjusting seat a from affecting the processing of the first station. The other limiting rod is located on the side of the station corresponding to the rotary orientation component 5 and cooperates with the pushing component to limit the adjusting seat a at that station, ensuring that the adjusting seat a can be accurately pushed to the first station for processing by the pushing block 12.

[0021] The moving component 3 is located on one side of the actuating side. The moving component 3 includes a mounting base 20, on which a clamping cylinder 21 is fixedly mounted. A moving seat 22 is fixedly mounted on the telescopic rod of the clamping cylinder 21. A feeding cylinder 23 is fixedly mounted on the moving seat 22. A feeding plate 24 that can extend from the actuating side to the top of the slide groove 9 is fixedly mounted on the telescopic rod of the feeding cylinder 23. Three locking slots 25 that match the adjusting seat a are arranged sequentially on the feeding plate 24. The three locking slots 25 are spaced equally and correspond to three working positions respectively. The extension direction of the telescopic rod of the feeding cylinder 23 is parallel to the extension direction of the slide groove 9. The material-feeding cylinder 23 drives the deflector plate 24 to move along the extension direction of the slide groove 9. The extension direction of the telescopic rod of the clamping cylinder 21 is perpendicular to the extension direction of the slide groove 9. The clamping cylinder 21 drives the moving seat 22 to move closer to or away from the slide rail assembly 2, thereby achieving the purpose of driving the deflector plate 24 closer to or away from the slide groove 9, so that the clamping slot 25 can engage or release the corresponding adjusting seat a. At each end of the moving seat 22 corresponding to the moving direction of the deflector plate 24, a buffer damper 13 is installed to cooperate with the deflector plate 24 to limit its movement, so as to avoid the deflector plate 24 and the moving seat 22 colliding and causing noise or damage.

[0022] The operation process of the adjustment seat a assembly machine provided in this embodiment is as follows: First, the adjustment seat feeding component 4 transports the unprocessed adjustment seat a from the feed port into the slide 9. Then, the first limit cylinder 19 drives the first limit rod to retract, and the pusher cylinder 10 drives the pusher block 12 to push the adjustment seat a to the first work station. The pusher cylinder 10 and the first limit cylinder 19 are reset, the rotation orientation component 5 is started and performs the first processing step. After processing is completed, the clamping cylinder 21 is started and drives the lever 24 to approach the slide 9, so that the adjustment seat a at the work station is clamped into the clamping slot 25. The second limit cylinder 19 drives the second limit rod to retract. At this time, the lever cylinder 23 is started and pulls the adjustment seat a to the lower position. At one station, the clamping cylinder 21 resets and drives the lever 24 away from the chute 9. Simultaneously, the second limit cylinder 19 resets, and the lever cylinder 23 resets. The pushing cylinder 10 pushes the next adjusting seat a to the first station. Then, the clamping cylinder 21 drives the lever 24 closer to the chute 9 and engages both adjusting seats a into the slot 25. At this point, both adjusting seats a are positioned by the lever 24 and the chute 9. Then, the rotational orientation component 5 and the screw mounting component 6 simultaneously begin processing the adjusting seats a. After processing, the above actions are repeated. The lever 24 pulls both adjusting seats a to the next station. Then, the lever 24 resets and re-engages the three adjusting seats a, performing corresponding processing. After processing, the lever 24 pulls all the adjusting seats a to the next station again, with the first adjusting seat a being pulled to the outlet of the chute 9. Finally, to repeat once more, while the lever 24 pulls the adjusting seat a to the next station, it pushes the adjusting seat a at the discharge port to the material distribution trough 15 for discharge.

[0023] The assembly machine in this embodiment has three strictly equidistant slots 25 on the push plate 24, which precisely correspond to the three equidistant workstations on the chute 9. Driven by the combined action of the push cylinder 23 and the clamping cylinder 21, each time the push plate 24 moves forward, its slots 25 precisely engage with the adjusting seat a at the workstation and apply a pushing force. This rigid limiting and pushing mechanism based on the slots 25 ensures that the adjusting seat a is fixed in position, precise in step distance, and stable in posture during the process of moving from one workstation to the next in the chute 9. The strict correspondence between the workstations and the slots 25 eliminates the cumulative error or offset during the transfer process, solving the problems of inaccurate positioning and jamming caused by defects in the conveying structure of existing semi-automatic production lines. In practical applications, the length of the chute 9 can be extended and the number of slots 25 can be increased according to the actual number of processing steps to meet different needs.
