[0040] See also Figure 5 As a preferred embodiment of the present invention, it may also have the following additional technical features: the driving structure 235 includes a sliding base 2351, a connecting rod 2352, a threaded rod 2353, and a second driving motor 2354. The sliding base 2351 is fixedly connected to the quality inspection table 21, the connecting rod 2352 is fixedly connected to the sliding base 2351, the threaded rod 2353 is rotatably connected to the sliding base 2351, the moving seat 231 is sleeved on the connecting rod 2352, the moving seat 231 is movably connected to the threaded rod 2353, the threads on both sides of the threaded rod 2353 are opposite, and the second driving motor 2354 is arranged on the sliding base 2351 and fixedly connected to the end of the threaded rod 2353. When the second driving motor 2354 is started, its rotational power is transmitted to the threaded rod 2353 through the transmission mechanism, so that the threaded rod 2353 rotates around its axis. When the threaded rod 2353 rotates, the moving seat 231 will move linearly along the direction of the connecting rod 2352.

[0041] See also Figure 6-Figure 7 As a preferred embodiment of the present invention, it may also have the following additional technical features: the quality inspection device 2 includes a limiting mechanism 24, the limiting mechanism 24 includes a limiting frame 241, an elastic member 242, a connecting rod 243 and a limiting assembly 244, the limiting frame 241 is embedded in the pressure plate 223, the limiting frame 241 is slidably connected to the pressure plate 223, allowing the limiting frame 241 to move within a limited range inside the pressure plate 223, the elastic member 242 is arranged between the limiting frame 241 and the pressure plate 223, providing a reset force and a buffer force, and the elastic member 242 is stretched and reset within a normal working range during the whole process, the connecting rod 243 is fixedly connected to the limiting frame 241, the connecting rod 243 slides through the fixed frame 221, the limiting assembly 244 is arranged on the fixed frame 221, and the limiting assembly 244 is connected to the connecting rod 243. In this embodiment, a magnetic bit is arranged on the connecting rod 243.

Because the magnetic member 2443 magnetically limits the connecting rod 243, the pressure plate 223 moves upward to first pull the elastic member 242 to stretch, and the limiting frame 241 keeps pressing the caster to limit the position, which can prevent the caster from moving upward with the pressure plate 223. Because the two sides of the caster are fixed by the suction cup 2332, the caster is quickly separated from the pressure plate 223 first, which can prevent the pressure plate 223 from causing the caster to be subjected to too much upward force during the upward movement, thereby preventing the caster from being damaged by being pulled. The pressure plate 223 continues to move upward to drive the limiting frame 241 to move upward, so that the limiting frame 241 and the pressure plate 2 23 abuts, and the process of the limit frame 241 moving upward drives the connecting rod 243 to move upward. The connecting rod 243 moves upward and resets, so that the magnetic position is out of contact with the magnetic part 2443, and the connecting rod 243 stops being adsorbed. Due to the action of the elastic part 242, the limit frame 241 moves upward and drives the connecting rod 243 to move upward to a suitable position, and then the second driving motor 2354 is started to drive the threaded rod 2353 to rotate in the opposite direction, so that the moving seat 231 drives the suction cup 2332 to move outward and reset through the positioning rod 232. The suction cup 2332 is reset to loosen the wheel body, and the caster after the compression test can be removed.

The connection between the lifting motor 1312 and the lifting frame 1311 realizes the automatic lifting of the second feeding hopper 1313, and the lifting and transportation of materials can be completed without human intervention, which not only reduces the labor intensity of workers, but also improves the automation level of the production line, and reduces errors and delays caused by human factors. The design of the lifting frame 1311 and the discharge channel 1314 is compact and reasonable, which makes full use of the vertical space and reduces the floor space of the production line. At the same time, it makes the entire second feeding mechanism 131 more stable and reliable, and reduces the risk of failure due to vibration and impact.

[0047] See also Fig.12As a preferred embodiment of the present invention, it may also have the following additional technical features: the rivet shaft conveying mechanism 14 includes a third feeding mechanism 141, a third vibration disk 142, a third conveying guide rail 143, a third pushing structure 144 and a third clamping structure 145. The discharge end of the third feeding mechanism 141 is arranged above the third vibration disk 142, the third pushing structure 144 is arranged at the starting end of the third conveying guide rail 143, the output end of the third vibration disk 142 is arranged between the third pushing structure 144 and the third conveying guide rail 143, the third clamping structure 145 is arranged between the end of the third conveying guide rail 143 and the rotating disk 11, and the third vibration disk 142 arranges the rivet shafts in order and The rivet shaft is transported to the designated position, thereby avoiding confusion and misalignment of the rivet shaft during the transportation process; at the same time, the third pushing structure 144 at the starting end of the third conveying guide rail 143 ensures that the rivet shaft can smoothly enter the guide rail, and the second clamping structure 135 at the end of the guide rail accurately clamps the rivet shaft and transports it to the assembly position on the rotating disk 11, ensuring the accuracy of transportation; through the continuous operation of the third feeding mechanism 141, the third vibration disk 142, the third conveying guide rail 143, the third pushing structure 144 and the third clamping structure 145, the rivet shaft can automatically and quickly complete the transportation process from the raw material to the assembly position. This automated transportation method greatly reduces manual intervention and improves the overall efficiency of the production line.

[0048] Specifically, in this embodiment, the third feeding mechanism 141 has the same structure as the second feeding mechanism 131 , and a lifting door 1315 is provided at one end of the discharge channel 1314 away from the lifting frame 1311 for controlling the number of rivet shafts falling.

[0049] Specifically, in this embodiment, the riveting mechanism 15 can adopt the specific mechanism of the existing caster assembly, and the riveting is achieved by a mechanical riveting machine or a pneumatic riveting machine. At the same time, sensors are equipped to detect the position of the assembly position 111 and the existence of parts. The PLC control system coordinates the actions of various components according to the sensor signals to ensure the smooth progress of the entire assembly process.

[0050] The working principle of the central control caster automatic assembly production line of the present embodiment is as follows: first, when one of the assembly positions 111 is located in front of the wheel body conveying mechanism 12, the first clamping structure 125 places the wheel body at the corresponding assembly position 111, then, the rotating disk 11 continues to rotate at an indexing rate, and when the assembly position 111 where the wheel body is placed is located in front of the wheel body conveying mechanism 12, the second clamping structure 135 places the support frame at the corresponding assembly position 111, then, the rotating disk 11 continues to rotate at an indexing rate, and when the assembly position 111 where the wheel body and the support frame are placed is located in front of the wheel body conveying mechanism 12, the third clamping structure 145 places the rivet The shaft is placed in the corresponding assembly position 111, and then the rotating disk 11 continues to rotate in an indexing manner, and the caster is riveted as a whole by relying on the riveting mechanism 15. The finished caster products after all the assembly are transported from the finished product conveying mechanism 16 to a collection box. At this time, the staff puts the caster into the placement groove 212, the wheel body abuts against the placement groove 212, and starts the second driving motor 2354 to drive the threaded rod 2353 to rotate. The rotation of the threaded rod 2353 drives the moving seats 231 on both sides to move toward the caster, so that the positioning rod 232 drives the suction cup 2332 to move toward the caster and contact the wheel body. At this time, the vacuum pump is started to suck the suction cup 233 through the vacuum pipe 2331. 2 is sucked out, and the suction cup 2332 is in a vacuum state to fix the wheel body, the second drive motor 2354 is turned off, and the first drive motor 234 is started again to drive the positioning rod 232 to rotate, and the rotation of the positioning rod 232 drives the caster to rotate, and the angle of the caster is finely adjusted to ensure that the caster is placed in an accurate position, the first drive motor 234 is turned off, and the hydraulic cylinder 222 is started again to drive the pressure plate 223 to move downward, and the pressure plate 223 moves downward to drive the limit frame 241 to move downward, and the limit frame 241 moves downward to drive the connecting rod 243 to move downward, and the connecting rod 243 moves downward so that the magnetic position on the connecting rod 243 is aligned with the magnetic part 2443 Due to the downward force of the pressure plate 223, the connecting rod 243 moves downward and slides in the magnetic part 2443. When the pressure plate 223 moves downward and contacts the caster, the limit frame 241 also contacts the caster to further limit the caster as a whole. The pressure plate 223 applies pressure to the caster to perform pressure resistance detection. The pressure sensor 213 detects the pressure force. The pressure sensor 213 transmits the detected data to the operating system for display. If the caster is deformed and damaged, it means that the caster quality is unqualified, otherwise it is qualified. Then the hydraulic cylinder 222 is started to drive the pressure plate 223 to move upward and disengage from the caster.

[0051] The central control caster automatic assembly production line of the present embodiment has a reasonable structural design and is easy to use. This structure can also be used to implement other equipment with similar usage requirements. In the present embodiment, the central control caster automatic assembly production line performs pressure testing on the assembled casters through a quality inspection device, which can screen out unqualified casters and prevent unqualified casters from being used in the final product, thereby ensuring the reliability and durability of the final product and effectively reducing the risk of product damage or safety accidents caused by caster failure.
