Description

Technical Field

[0001] This invention relates to the field of toy product processing technology, specifically to a multi-station collaborative automated pressing and assembly equipment for toy cars, and also to a method thereof. Background Technology

[0002] In the toy car manufacturing industry, axles and wheels need to be assembled. Existing toy car axle and wheel assembly equipment faces numerous technical bottlenecks in practical applications. Some equipment uses traditional manual or semi-automatic assembly methods, which not only result in low production efficiency, making it difficult to meet the needs of large-scale production, but also lead to assembly errors due to manual operation, resulting in inconsistent product quality.

[0003] Patent CN221494947U discloses an automatic toy wheel assembly device. The device places pre-produced toy wheels and axles into an automatic wheel feeding device and an automatic axle feeding device, respectively. The automatic wheel feeding device feeds the wheels to the wheel side pressing device. After the wheel axle is adjusted by the wheel axle flipping device, wheel axle ejection device, and wheel axle drive device, it is conveyed to the wheel side pressing device. The wheel side pressing device tightly fits two wheels with one wheel axle and presses the two wheels into it. Finally, the assembled wheels and axles are collected by the unloading device.

[0004] Although the above solution achieves efficient pressing of wheels and axles, each time the axle is pushed into the axle groove on the axle feed block, the axle slides and rubs against the groove during this process. Furthermore, the axle is not fixed, and as the axle feed block moves towards the two wheel side pressing devices, the axle may still shift. This causes the axle to move again under the push of the wheels when pressing two wheels, resulting in friction between the axle and the groove. This leads to wear on the axle groove, which in turn reduces the axial height of the subsequent axle after entering the groove, affecting the accuracy of the connection between the axle and the wheel, and potentially causing pressing failure. Summary of the Invention

[0005] To address the aforementioned issues, a multi-station collaborative automated pressing and assembly equipment for toy cars is provided. By setting up an axle supply mechanism, two wheel supply mechanisms, and a pressing drive mechanism, it effectively ensures that the axes of each axle can be kept at the same height, thereby achieving precise docking between the axle and the two wheel supply mechanisms, and improving the automated assembly efficiency and assembly accuracy of the toy car axles and wheels.

[0006] To address the problems of existing technologies, this invention provides a multi-station collaborative automated pressing and assembly equipment for toy cars, including a wheel axle supply mechanism and a wheel pressing mechanism. The wheel axle supply mechanism includes two vertical plates, a first turntable, and multiple supporting structures. The two vertical plates are arranged parallel to each other, and the first turntable is located between the two vertical plates. A rotating shaft is located in the middle of the first turntable, and both ends of the rotating shaft are connected to the two vertical plates respectively. Multiple supporting structures are arranged at equal intervals around the axis of the rotating shaft on the first turntable. Each supporting structure includes a mounting plate, at least two positioning wheel sets, and a first self-clamping structure. The two positioning wheel sets are arranged on the mounting plate and symmetrically about the middle surface of the mounting plate. The first self-clamping structure is used to drive the positioning wheel sets to clamp the wheel axle. The wheel pressing mechanism includes two wheel supply mechanisms and a pressing drive mechanism. The two wheel supply mechanisms are respectively located on both sides of the wheel axle supply mechanism, and the pressing drive mechanism is used to drive the two wheel supply mechanisms to move simultaneously toward the wheel axle.

[0007] Preferably, the positioning wheel assembly includes a first guide rod, two first movable blocks, and two rollers; both ends of the first guide rod are fixedly connected to the mounting plate; the two first movable blocks are slidably connected to the first guide rod, and one side of the first movable block is connected to a first self-clamping structure; the two rollers are respectively connected to the two first movable blocks.

[0008] Preferably, the first self-clamping structure includes a second guide rod and two V-blocks; the middle part of the second guide rod is connected to the mounting plate; the two V-blocks are slidably disposed at both ends of the second guide rod, and the V-blocks are provided with grooves, the two grooves forming a V shape, and the two first moving blocks in the positioning wheel shaft are slidably connected to the two grooves respectively.

[0009] Preferably, the openings of the two V-blocks are arranged opposite to each other, and the opening directions of the two grooves on the V-blocks are the same as the opening direction of the V-blocks. Two first springs are sleeved on the second guide rod, and the two ends of the first springs abut against the middle of the V-blocks and the second guide rod, respectively.

[0010] Preferably, the wheel and axle supply mechanism further includes two first opening structures, which are respectively disposed on the upper and lower sides of the first turntable. The first opening structures are used to drive the two rollers in the positioning wheel set to move away from each other.

[0011] Preferably, the wheel supply mechanism includes a fixed shaft, a second turntable, and a plurality of second self-clamping structures; the second turntable is horizontally disposed at the upper end of the fixed shaft and is coaxial with the fixed shaft; the plurality of second self-clamping structures are equally spaced on the second turntable, and the second self-clamping structures are used to maintain the clamping and fixing of the wheel.

[0012] Preferably, the second self-clamping structure includes a connecting rod, a limiting plate, and a self-clamping assembly; one end of the connecting rod is connected to the second turntable; the limiting plate is connected to the other end of the connecting rod; and the self-clamping assembly is used to clamp the wheel.

[0013] Preferably, the self-clamping assembly includes a connecting ring and a second spring; the connecting ring is slidably disposed on the connecting rod, and multiple drive arms are rotatably connected to the connecting ring, one end of each drive arm is rotatably connected to an L-shaped clamping block, the middle of the L-shaped clamping block being axially connected to a limiting plate; the two ends of the second spring abut against the ends of the connecting ring and the connecting rod, respectively.

[0014] Preferably, the wheel supply mechanism further includes a second opening structure, which is disposed on the top of the fixed shaft. The second opening structure corresponds to two second self-clamping structures and is used to apply a force toward the fixed shaft to the connecting ring.

[0015] A multi-station collaborative automated pressing and assembly method for toy cars, applied to the aforementioned multi-station collaborative automated pressing and assembly equipment for toy cars, includes the following steps:

[0016] S1. When the load-bearing structure rotates to the top of the first turntable, the axle moves from one side of the positioning wheel assembly along its own axis toward the positioning wheel assembly;

[0017] S2. After the wheel axle enters the positioning wheel group, the first self-clamping structure drives the positioning wheel group to clamp the wheel axle, and the first turntable drives the wheel axle to rotate between the two wheel supply mechanisms.

[0018] S3, The second turntable in the wheel supply mechanism rotates the wheel to one end of the axle;

[0019] S4. The press-fitting drive mechanism drives the two wheel supply mechanisms to move closer to each other, so that the two wheels are connected to the axle.

[0020] S5. The second opening and closing structure controls the second self-clamping structure to release the wheel, while the press-fitting drive mechanism drives the two vehicle supply mechanisms to move away from each other.

[0021] S6. When the first turntable drives the pressed wheels and axles to rotate to the bottom, the first opening structure drives the first self-clamping structure to release the pressed wheels and axles.

[0022] The advantages of this invention compared to the prior art are:

[0023] 1. In this invention, when the press-fitting drive mechanism applies force to the axle through the wheel provided by the wheel supply mechanism, rolling friction occurs between the axle and the positioning wheel group, which reduces the wear of the positioning wheel group during the movement of the axle and effectively ensures that the axis of each axle can be kept at the same height. This achieves precise docking between the axle and the two wheel supply mechanisms, and improves the automated assembly efficiency and assembly accuracy of the axle and wheel of the toy car.

[0024] 2. In this invention, the first self-clamping structure provides the same force to the two rollers, so that the rollers on both sides of the axle wear evenly. After the rollers wear, the first self-clamping structure drives the first moving block to move along the first guide rod, thereby compensating for the gap change caused by wear. This effectively solves the problem that roller wear may cause the axle docking height deviation and ensures the height consistency when the axle and the wheel supply mechanism are docked.

[0025] 3. In this invention, the V-block moves horizontally towards the center along the second guide rod, while the second guide rod restricts the movement of the V-block, ensuring that the V-block remains in a horizontal state during the movement. Therefore, the two ends of the V-block move synchronously, and the V-block can apply the same reaction force to the two rollers through the two sliding grooves and the two first moving blocks, ensuring that the clamping force of the rollers on the axle is balanced, thereby achieving a stable and uniform clamping effect on the axle and ensuring that the wear of the two rollers is the same.

Detailed Implementation

[0038] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figures 1 to 11As shown: A multi-station collaborative automated pressing and assembly equipment for toy cars includes a wheel axle supply mechanism 1 and a wheel pressing mechanism. The wheel axle supply mechanism 1 includes two vertical plates 11, a first turntable 12, and multiple supporting structures 13. The two vertical plates 11 are arranged parallel to each other, and the first turntable 12 is located between the two vertical plates 11. A rotating shaft 121 is located in the middle of the first turntable 12, and both ends of the rotating shaft 121 are connected to the two vertical plates 11 respectively. Multiple supporting structures 13 are arranged at equal intervals around the axis of the rotating shaft 121 on the first turntable 12. Each supporting structure 13 includes a mounting plate 131, at least two positioning wheel sets 132, and a first self-clamping mechanism. Structure 133, two positioning wheel sets 132 are mounted on mounting plate 131 and symmetrically arranged about the middle surface of mounting plate 131. The first self-clamping structure 133 is used to drive the positioning wheel sets 132 to clamp the wheel axle. The wheel pressing mechanism includes two wheel supply mechanisms 2 and a pressing drive mechanism 3. The two wheel supply mechanisms 2 are respectively arranged on both sides of the wheel axle supply mechanism 1. The pressing drive mechanism 3 is used to drive the two wheel supply mechanisms 2 to move towards the wheel axle at the same time. The pressing drive mechanism 3 includes a bidirectional slide 31. The bidirectional slide 31 is connected to the two wheel supply mechanisms 2. The bidirectional slide 31 drives the two wheel supply mechanisms 2 to move closer to or further away from each other.

[0040] When the equipment is running, the axle supply mechanism 1 starts rotating on its shaft 121, driving the first turntable 12 to rotate. When one of the bearing structures 13 rotates to its highest point, the axle moves along its own axis, passing through two symmetrically arranged positioning wheel sets 132 on the mounting plate 131. The positioning wheel sets 132 provide two force points for the axle, ensuring the stability of the axle. The first self-clamping structure 133 drives the positioning wheel sets 132 to clamp the axle, preventing the axle from shaking during the subsequent rotation of the first turntable 12. As the first turntable 12 continues to rotate, when the bearing structure 13 carrying the axle rotates between the two wheel supply mechanisms 2, the two wheel supply mechanisms 2 located on both sides of the axle supply mechanism 1 start working, synchronously delivering the two wheels to both ends of the axle. Subsequently, the press-fit drive mechanism 3 starts, driving the two wheel supply mechanisms 2 to move closer to each other. Since the wheels and axles usually use an interference fit, when one of the wheels contacts the end of the axle first, the wheel will push the axle to move along its own axis. At this time, a force is generated between the axle and the positioning wheel sets 132. Rolling friction has low resistance and causes less wear on the positioning wheel assembly 132 until both wheels are in contact with the axle, at which point the axle stops moving. The two wheels are then fixedly connected to the axle during their opposite movement. After connection, the pressing drive mechanism 3 drives the two wheel supply mechanisms 2 to move away from each other, and the first turntable 12 rotates again, allowing the subsequent axle to enter between the two wheel supply mechanisms 2. At the same time, the pressed wheels and axles fall off the bearing structure 13 and enter the next process. Through the coordinated operation of the axle supply mechanism 1, the two wheel supply mechanisms 2, and the pressing drive mechanism 3, the positioning wheel assembly 132 and the first self-clamping structure 133 stabilize the axle, and the pressing drive mechanism 3 achieves synchronous pressing of the wheels. By utilizing the rolling friction between the axle and the positioning wheel assembly 132, the wear of the positioning wheel assembly 132 during the movement of the axle is reduced, effectively ensuring that the axes of each axle can be kept at the same height. This achieves precise docking of the axle and the two wheel supply mechanisms 2, improving the automated assembly efficiency and assembly accuracy of the toy car axle and wheel.

[0041] Reference Figure 3 and Figure 4 As shown: The positioning wheel assembly 132 includes a first guide rod 1321, two first moving blocks 1322 and two rollers 1323; both ends of the first guide rod 1321 are fixedly connected to the mounting plate 131; the two first moving blocks 1322 are slidably connected to the first guide rod 1321, and one side of the first moving block 1322 is connected to the first self-clamping structure 133; the two rollers 1323 are respectively connected to the two first moving blocks 1322.

[0042] When the bearing structure 13 rotates to its highest point under the drive of the first turntable 12, the axle begins to move along its own axis and passes between the two rollers 1323. During this process, rolling friction occurs between the axle and the rollers 1323. Compared with sliding friction, this friction method can effectively reduce the wear on the rollers 1323. Subsequently, when the wheel contacts the axle and pushes the axle to move, rolling friction occurs again between the axle and the rollers 1323. Although the rolling friction is small, long-term operation will still cause wear on the rollers 1323. At this time, the first self-clamping structure 1 connected to the first moving block 1322... When the first self-clamping structure 133 is activated, it drives the two first moving blocks 1322 to move synchronously, so that the two rollers 1323 apply the same force to the axle at the same time. This ensures that the wear of the two rollers 1323 and the axle is always consistent. As the rollers 1323 wear, under the continuous action of the first self-clamping structure 133, the two rollers 1323 can move towards the axle at the same time, thereby compensating for the gap change caused by wear. This effectively solves the problem that the wear of the rollers 1323 may cause the axle docking height deviation, and ensures the height consistency when the axle docks with the wheel supply mechanism 2.

[0043] Reference Figure 3 and Figure 5 As shown: The first self-clamping structure 133 includes a second guide rod 1331 and two V-shaped blocks 1332; the middle part of the second guide rod 1331 is connected to the mounting plate 131; the two V-shaped blocks 1332 are slidably disposed at both ends of the second guide rod 1331, and the V-shaped blocks 1332 are provided with grooves, the two grooves forming a V shape, and the two first moving blocks 1322 in the positioning wheel shaft are slidably connected to the two grooves respectively.

[0044] As the axle begins to pass through the two rollers 1323, it exerts a force on each roller 1323 that moves away from each other. The rollers 1323, after receiving this force, transmit it to the groove of the V-block 1332 via the first movable block 1322 connected to them. As the first movable block 1322 slides within the groove, it exerts a force on the V-block 1332 towards the center of the second guide rod 1331, causing the V-block 1332 to translate along the second guide rod 1331 towards the center. 1331 restricts the movement of V-block 1332, ensuring that V-block 1332 remains in a translational state during movement. Therefore, both ends of V-block 1332 move synchronously. V-block 1332 can apply the same reaction force to the two rollers 1323 through the two slides and the two first moving blocks 1322, ensuring that the clamping force of the rollers 1323 on the axle is balanced, thereby achieving a stable and uniform clamping effect on the axle and ensuring that the two rollers 1323 wear the same.

[0045] Reference Figure 5As shown: the openings of the two V-blocks 1332 are arranged opposite to each other, and the opening directions of the two sliding grooves on the V-blocks 1332 are the same as the opening direction of the V-blocks 1332. Two first springs 1333 are sleeved on the second guide rod 1331, and the two ends of the first springs 1333 abut against the middle of the V-blocks 1332 and the second guide rod 1331, respectively.

[0046] When the axle begins to pass through the gap between the two rollers 1323, the axle applies a force to the rollers 1323 on both sides, causing them to move away from each other. After being subjected to this force, the rollers 1323 transmit the force to the groove of the V-block 1332 via the first moving block 1322. Under the influence of the special shape and positional relationship of the groove, the first moving block 1322 pushes the V-block 1332 to move towards the center of the second guide rod 1331. During this process, the first spring 1333, which is sleeved on the second guide rod 1331, is compressed. 33 will apply a thrust toward the end of the second guide rod 1331 to the V-block 1332, causing the V-block 1332 to tend to move toward the end. When the V-block 1332 moves toward the end of the first guide rod 1321, it applies a force to the two first moving blocks 1322 to move closer to each other through the slide groove, thereby driving the roller 1323 to clamp the axle. Through the synergistic effect of the first spring 1333, the two specially arranged V-blocks 1332 and the slide groove, the self-clamping function without additional drive equipment is realized.

[0047] Reference Figure 3 and Figure 6 As shown: The wheel and axle supply mechanism 1 also includes two first opening structures 14, which are respectively arranged on the upper and lower sides of the first turntable 12. The first opening structures 14 are used to drive the two rollers 1323 in the positioning wheel set 132 to move away from each other.

[0048] Specifically, the first opening structure 14 includes two first linear actuators 141 and two V-shaped push blocks 142. The two first linear actuators 141 are respectively disposed on the two vertical plates 11, and the two V-shaped push blocks 142 are respectively disposed on the output ends of the two first linear actuators 141. The middle part of the V-shaped push block 142 is provided with a through hole corresponding to the second guide rod 1331.

[0049] During the loading of the axle, the first opening structure 14 located on the upper side of the first turntable 12 is activated. The two first linear actuators 141 in the first opening structure 14 are activated simultaneously. The two first linear actuators 141 synchronously drive the two V-shaped push blocks 142 to slide along the second guide rod 1331 towards the center. After the V-shaped push block 142 contacts the V-shaped block 1332, it pushes the V-shaped block 1332 to move towards the center against the elastic force of the first spring 1333. Through the transmission between the sliding groove of the V-shaped block 1332 and the first moving block 1322, the two rollers 1323 synchronously separate outward, forming a sufficient space. To facilitate axle loading, after the axle is precisely placed between the rollers 1323, the first linear actuator 141 drives the V-shaped push block 142 to return to its initial position, releasing the constraint on the V-shaped block 1332. At this time, the compressed first spring 1333 releases its elastic potential energy, pushing the V-shaped block 1332 to slide towards the end of the second guide rod 1331. The V-shaped block 1332 drives the two first moving blocks 1322 to move towards each other through the sliding groove, so that the two rollers 1323 clamp the axle, thereby avoiding friction between the axle and the rollers 1323 during the axle loading process and reducing the wear of the rollers 1323.

[0050] Reference Figure 7 and Figure 8 As shown: The wheel supply mechanism 2 includes a fixed shaft 21, a second turntable 22 and a plurality of second self-clamping structures 23; the second turntable 22 is horizontally arranged at the upper end of the fixed shaft 21 and is coaxial with the fixed shaft 21; the plurality of second self-clamping structures 23 are equally spaced on the second turntable 22, and the second self-clamping structures 23 are used to maintain the clamping and fixing of the wheel.

[0051] After the second self-clamping structure 23 clamps and fixes the wheel, the second turntable 22 begins to rotate around the axis of the fixed shaft 21. At this time, the first turntable 12 of the wheel axle supply mechanism 1 also operates synchronously. When the first turntable 12 delivers the axle between the two wheel supply mechanisms 2, the second turntable 22 delivers the second self-clamping structure 23 holding the wheel to the end of the axle. Immediately afterwards, the press-fit drive mechanism 3 starts, driving the wheels on the two wheel supply mechanisms 2 to move towards the axle simultaneously. Through interference fit and other methods, a stable connection between the wheel and the axle is achieved. After completion, the second self-clamping structure 23 releases its grip on the wheel, and the pressing drive mechanism 3 drives the two wheel supply mechanisms 2 to move away from each other. Subsequently, the first turntable 12 rotates, transferring the wheel and axle that have been pressed out, while simultaneously conveying the unpressed axle between the two wheel supply mechanisms 2. The second turntable 22 also moves synchronously, conveying the next second self-clamping structure 23 holding the wheel to one end of the axle, preparing for the next round of pressing. Through the coordinated operation of the first turntable 12 and the second turntable 22, continuous pressing of axles and wheels is achieved.

[0052] Reference Figure 8 and Figure 9 As shown: The second self-clamping structure 23 includes a connecting rod 231, a limiting plate 232, and a self-clamping assembly 233; one end of the connecting rod 231 is connected to the second turntable 22; the limiting plate 232 is connected to the other end of the connecting rod 231; the self-clamping assembly 233 is used to clamp the wheel.

[0053] When performing wheel clamping, the wheel side is first tightly pressed against the limiting plate 232 to provide a reference surface for wheel positioning. Then, the self-clamping assembly 233 clamps the wheel from all sides. Since the self-clamping assembly 233 applies clamping force evenly, each wheel is fixed in the same position on the limiting plate 232, which ensures the accuracy of the wheel when it is subsequently connected to the axle. Next, the second turntable 22 drives the second self-clamping structure 23 to rotate around the axis of the fixed shaft 21. When it rotates to the predetermined position for connection with the axle, the pressing drive mechanism 3 is activated, driving the two wheel supply mechanisms 2 to move closer to each other. At this time, the limiting plate 232, as the force transmission component, applies a force to the wheel towards the axle. In this process, the pressure on the wheel is evenly distributed to the entire surface in contact with the limiting plate 232, avoiding excessive local stress, thereby effectively preventing the wheel from deforming due to local stress concentration during the pressing process.

[0054] Reference Figure 9 and Figure 10 As shown: The self-clamping assembly 233 includes a connecting ring 2331 and a second spring 2334; the connecting ring 2331 is slidably disposed on the connecting rod 231, and a plurality of driving arms 2332 are rotatably connected to the connecting ring 2331. One end of the driving arm 2332 is rotatably connected to an L-shaped clamping block 2333, and the middle part of the L-shaped clamping block 2333 is axially connected to the limiting plate 232; the two ends of the second spring 2334 abut against the ends of the connecting ring 2331 and the connecting rod 231, respectively.

[0055] Before clamping the wheel, multiple L-shaped clamping blocks 2333 are unfolded to form an open space, making it easy to place the wheel between the multiple L-shaped clamping blocks 2333. After the wheel is placed in place, the compressed second spring 2334 releases its elastic potential energy, pushing the connecting ring 2331 to move towards the end of the connecting rod 231. During the movement, the connecting ring 2331 converts its linear motion into the rotational motion of the L-shaped clamping blocks 2333 through multiple drive arms 2332. The L-shaped clamping blocks 2333 rotate around the axial connection between themselves and the limiting plate 232, gradually closing and tightly abutting against the circumferential surface of the wheel. At the same time, the second spring 2334 continuously applies a pushing force, so that the L-shaped clamping blocks 2333 always maintain the clamping force on the wheel, thereby ensuring that the wheel is firmly clamped during the rotation of the wheel driven by the second turntable 22.

[0056] Reference Figure 8 and Figure 11As shown: The wheel supply mechanism 2 also includes a second opening structure 24, which is disposed on the top of the fixed shaft 21. The second opening structure 24 corresponds to two second self-clamping structures 23, and the second opening structure 24 is used to apply a force toward the fixed shaft 21 to the connecting ring 2331.

[0057] Specifically, the second opening structure 24 includes a third guide rod 241, two compression components 242, and a synchronous drive component 243. The middle part of the third guide rod 241 is fixedly connected to the top of the fixed shaft 21. The two compression components 242 are respectively disposed at both ends of the third guide rod 241. The compression component 242 includes a sliding sleeve 2421 and a baffle 2422. The sliding sleeve 2421 is slidably connected to the third guide rod 241, and the baffle 2422 is fixedly connected to the connecting ring 2331. The synchronous drive component 243 includes a second linear driver 2431 and two connecting arms 2432. One end of each connecting arm 2432 is axially connected to the output end of the second linear driver 2431, and the other end of each connecting arm 2432 is axially connected to the two sliding sleeves 2421.

[0058] The two second self-clamping structures 23 corresponding to the second opening structure 24 are respectively located at the axle docking station and the wheel loading station. When the wheel at the axle docking station completes its connection with the axle, the second opening structure 24 is activated, and the second linear actuator 2431 outputs force to drive the two connecting arms 2432 to retract and move closer together. The connecting arms 2432 pull the sliding sleeves 2421 connected to their shafts, causing the two sliding sleeves 2421 to move closer together along the third guide rod 241. The sliding sleeves 2421 drive the connecting rings 2331 in the second self-clamping structure 23 through the baffle 2422, causing the connecting rings 2331 to move towards... As the second turntable 22 moves in the middle and the connecting ring 2331 moves, the drive arm 2332 drives multiple L-shaped clamping blocks 2333 to rotate and unfold around the shaft connection with the limiting plate 232. The originally clamped wheel is unconstrained, and the second self-clamping structure 23 is unloaded. At the same time, the second self-clamping structure 23 at the wheel loading station also unfolds synchronously due to the same linkage. After the pressing drive mechanism 3 drives the two wheel supply mechanisms 2 to move away from each other, the wheel is loaded, thus realizing the synchronous control of the loading and unloading of the second self-clamping structure 23 and simplifying the control steps.

[0059] A multi-station collaborative automated pressing and assembly method for toy cars, applied to the aforementioned multi-station collaborative automated pressing and assembly equipment for toy cars, is characterized by comprising the following steps:

[0060] S1. When the bearing structure 13 rotates to the uppermost end of the first turntable 12, the axle moves from one side of the positioning wheel group 132 along its own axis toward the positioning wheel group 12;

[0061] S2. After the axle enters the positioning wheel assembly 132, the first self-clamping structure 133 drives the positioning wheel assembly 132 to clamp the axle, and the first turntable 12 drives the axle to rotate between the two wheel supply mechanisms 2.

[0062] S3, the second turntable 22 in the wheel supply mechanism 2 rotates the wheel to one end of the axle;

[0063] S4. Press-fitting drive mechanism 3 drives two wheel supply mechanisms 2 to move closer to each other, so that the two wheels are connected to the axle.

[0064] S5, the second opening and closing structure controls the second self-clamping structure 23 to release the wheel, while the press-fitting drive mechanism 3 drives the two vehicle supply mechanisms to move away from each other.

[0065] S6. When the first turntable 12 drives the pressed wheels and axles to rotate to the bottom, the first opening structure 14 drives the first self-clamping structure 133 to release the pressed wheels and axles.
