Description

Technical Field

[0001] The present invention relates to the technical field of toy product processing, in particular to a multi-station collaborative automatic pressing and assembling device for a toy car, and also to a method. Background Art

[0002] In the toy car manufacturing industry, axles and wheels need to be assembled. Existing axle and wheel assembly equipment for toy cars faces numerous technical bottlenecks in practical application. Some equipment utilizes traditional manual or semi-automatic assembly methods, resulting in low production efficiency and difficulty meeting the demands of large-scale production. Furthermore, manual operation is prone to assembly errors, resulting in inconsistent product quality.

[0003] The patent with announcement number CN221494947U discloses an automatic assembly device for toy wheels, which places the produced toy wheels and axles on the wheel automatic feeding device and the axle automatic feeding device respectively. The wheel automatic feeding device feeds the wheel side pressing device. After the axle flipping device, the axle ejection device and the axle driving device adjust the position of the axle, the axle is transported to the wheel side pressing device. The wheel side pressing device is used to tightly fit two wheels with an axle and press the two wheels into it. Finally, the assembled wheels and axles are collected through the unloading device.

[0004] Although the above scheme achieves efficient press-fitting of the wheels and axles, each time the axle is pushed into the axle groove on the axle forward feed block, the axle slides and rubs against the axle groove during this process, and the axle is not fixed. During the process of the axle forward feed block moving toward the two wheel side pressure devices, the axle may still be displaced, resulting in the axle moving under the push of the wheels when the two wheels are press-fitted, causing the axle to rub against the axle groove again, which will cause the axle groove to wear, and then cause the axis height of the subsequent axle to decrease after entering the axle groove, affecting the docking accuracy of the axle and the wheel, and may cause press-fitting failure.

[0009] Preferably, the openings of the two V-shaped blocks are arranged back to back, and the opening direction of the two sliding grooves on the V-shaped block is the same as the opening direction of the V-shaped block. Two first springs are sleeved on the second guide rod, and the two ends of the first spring are respectively abutted against the middle of the V-shaped block and the second guide rod.

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

[0015] A multi-station collaborative automatic pressing and assembling method for a toy car is applied to the above-mentioned multi-station collaborative automatic pressing and assembling equipment for a toy car, comprising the following steps: S1, when the bearing structure rotates to the upper end of the first turntable, the axle moves from one side of the positioning wheel group along its own axis toward the positioning wheel group; S2: After the wheel axle enters the positioning wheel assembly, the first self-clamping structure drives the positioning wheel assembly to clamp the wheel axle, and the first turntable drives the wheel axle to rotate between the two wheel supply mechanisms; S3, the second turntable in the wheel supply mechanism rotates the wheel to one end of the axle; S4, the press-fitting drive mechanism drives the two wheel supply mechanisms to move closer to each other, so that the two wheels are plugged into the axle; S5, the second opening and closing structure controls the second self-clamping structure to release the wheel, and at the same time the press-fitting drive mechanism drives the two vehicle supply mechanisms away from each other; S6.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the press-fit drive mechanism of the present invention applies force to the axle through the wheel provided by the wheel supply mechanism, rolling friction occurs between the axle and the positioning wheel assembly, reducing the wear of the positioning wheel assembly during the movement of the axle, effectively ensuring that the axes of each axle can be maintained at the same height, thereby achieving precise docking of the axle with the two wheel supply mechanisms, and improving the efficiency and assembly accuracy of the automated assembly of the toy car axle and wheel; 2. The first self-clamping structure of the present invention applies equal force to the two rollers, ensuring uniform wear of the rollers on both sides of the axle. Furthermore, 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 of height deviation of the axle docking caused by roller wear, ensuring height consistency when the axle and the wheel feeding mechanism are docked. 3. In the present invention, the V-shaped block translates toward the middle along the second guide rod, and the second guide rod limits the movement of the V-shaped block, ensuring that the V-shaped block always maintains a translation state during the movement. Therefore, the two ends of the V-shaped block move synchronously. The V-shaped block can apply a reaction force of exactly the same magnitude to the two rollers through the two slide 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 two rollers have the same wear.

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 11 As shown: A toy car multi-station collaborative automated pressing and assembly equipment, including an axle feeding mechanism 1 and a wheel pressing mechanism; the axle feeding mechanism 1 includes two vertical plates 11, a first turntable 12 and a plurality of bearing structures 13, the two vertical plates 11 are arranged parallel to each other, the first turntable 12 is arranged between the two vertical plates 11, a rotating shaft 121 is provided in the middle of the first turntable 12, and the two ends of the rotating shaft 121 are respectively connected to the two vertical plates 11, and a plurality of bearing structures 13 are arranged on the first turntable 12 at equal intervals around the axis of the rotating shaft 121, and the bearing structure 13 includes a mounting plate 131, at least two positioning wheel groups 132 and a first self-clamping Structure 133, two positioning wheel groups 132 are arranged on the mounting plate 131 and are symmetrically arranged about the middle surface of the mounting plate 131, and the first self-clamping structure 133 is used to drive the positioning wheel group 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 axle supply mechanism 1, the pressing drive mechanism 3 is used to drive the two wheel supply mechanisms 2 to move toward 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, and the bidirectional slide 31 drives the two wheel supply mechanisms 2 to move closer to or away from each other.

[0021] When the equipment is running, the rotating shaft 121 of the axle feeding mechanism 1 starts, driving the first turntable 12 to rotate. When one of the supporting structures 13 rotates to the highest point, the axle moves along its own axis and passes through the two positioning wheel groups 132 symmetrically arranged on the mounting plate 131. The positioning wheel groups 132 provide two force points for the axle to ensure the stability of the axle state, and the first self-clamping structure 133 drives the positioning wheel group 132 to clamp the axle to prevent the axle from shaking during the subsequent rotation of the first turntable 12. As the first turntable 12 continues to rotate, when the supporting structure 13 carrying the axle rotates to between the two wheel feeding mechanisms 2, the two wheel feeding mechanisms 2 located on both sides of the axle feeding mechanism 1 start working and synchronously deliver the two wheels to the two ends of the axle. Subsequently, the pressing drive mechanism 3 is started to drive the two wheel feeding mechanisms 2 to approach each other. Since the wheel and the axle usually adopt 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 group 132 The wheel axle 132 is fixed to the wheel axle 110 by the first self-clamping structure 133 and the second self-clamping structure 134 of the wheel axle 110 is fixed to the wheel axle 110 by the first self-clamping structure 133 of the wheel axle 110.

[0022] Reference Figure 3 and Figure 4 As shown: the positioning wheel group 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.

[0023] When the bearing structure 13 rotates to the highest point driven by the first turntable 12, the axle starts to move along its own axis and passes between the two rollers 1323. In this process, rolling friction is generated between the axle and the rollers 1323. Compared with sliding friction, this friction method can effectively reduce the wear of the rollers 1323. Subsequently, when the wheel contacts the axle and pushes the axle to move, rolling friction is generated again between the axle and the rollers 1323. Although the rolling friction is small, long-term operation will still cause wear of the rollers 1323. At this time, the first self-clamping structure 1 connected to the first moving block 1322 33 comes into play, the first self-clamping structure 133 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, which ensures that the degree of 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 toward the axle at the same time, thereby compensating for the gap change caused by wear, effectively solving the problem of axle docking height deviation caused by the wear of the rollers 1323, and ensuring the height consistency of the axle and the wheel supply mechanism 2 when docking.

[0024] 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 arranged at both ends of the second guide rod 1331, and a sliding groove is opened on the V-shaped block 1332, and the two sliding grooves form a V shape. The two first moving blocks 1322 in the positioning wheel shaft are slidably connected to the two sliding grooves respectively.

[0025] When the axle starts to pass through the two rollers 1323, during this process, the axle exerts a force on the rollers 1323 on both sides to move away from each other. After the rollers 1323 are subjected to the force, the force is transmitted to the slide groove of the V-shaped block 1332 through the first movable block 1322 connected thereto. When the first movable block 1322 slides in the slide groove, it exerts a force on the V-shaped block 1332 toward the middle of the second guide rod 1331, causing the V-shaped block 1332 to move horizontally toward the middle along the second guide rod 1331, and the second guide rod 1331 is rotated. 1331 limits the movement of the V-block 1332, ensuring that the V-block 1332 always maintains a translational state during the movement. Therefore, the two ends of the V-block 1332 move synchronously. The V-block 1332 can apply a reaction force of exactly the same magnitude to the two rollers 1323 through the two slide grooves and the two first moving blocks 1322, ensuring that the clamping force of the roller 1323 on the axle is balanced, thereby achieving a stable and uniform clamping effect on the axle, and ensuring that the two rollers 1323 have the same wear.

[0026] Reference Figure 5As shown: the openings of the two V-shaped blocks 1332 are arranged back to back, and the opening direction of the two sliding grooves on the V-shaped block 1332 is the same as the opening direction of the V-shaped block 1332, and two first springs 1333 are sleeved on the second guide rod 1331, and the two ends of the first spring 1333 are respectively in contact with the middle part of the V-shaped block 1332 and the second guide rod 1331.

[0027] When the axle starts to pass through the gap between the two rollers 1323, the axle exerts a force on the rollers 1323 on both sides to move away from each other. After the rollers 1323 are subjected to the force, the force is transmitted to the slide groove of the V-shaped block 1332 through the first moving block 1322. Under the action of the special shape and position relationship of the slide groove, the first moving block 1322 pushes the V-shaped block 1332 to move toward the middle of the second guide rod 1331. In this process, the first spring 1333 sleeved on the second guide rod 1331 is compressed, and the first spring 1333 is compressed. 33 will apply a thrust toward the end of the second guide rod 1331 to the V-shaped block 1332, so that the V-shaped block 1332 has a tendency to move toward the end. When the V-shaped block 1332 moves toward the end of the first guide rod 1321, it applies a force to move the two first moving blocks 1322 closer to each other through the slide groove, thereby driving the roller 1323 to clamp the axle. Through the coordinated action of the first spring 1333, the two specially arranged V-shaped blocks 1332 and the slide groove, a self-clamping function is achieved without the need for additional driving equipment.

[0028] Reference Figure 3 and Figure 6 As shown, the axle supply mechanism 1 further 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 group 132 to move away from each other.

[0029] Specifically, the first opening structure 14 includes two first linear drivers 141 and two V-shaped push blocks 142. The two first linear drivers 141 are respectively arranged on the two vertical plates 11, and the two V-shaped push blocks 142 are respectively arranged on the output ends of the two first linear drivers 141, and a through hole corresponding to the second guide rod 1331 is opened in the middle of the V-shaped push block 142.

[0030] When the wheel axle is loaded, the first opening structure 14 located on the upper side of the first turntable 12 is started, and the two first linear drivers 141 in the first opening structure 14 are started at the same time. The two first linear drivers 141 synchronously drive the two V-shaped push blocks 142 to slide toward the middle along the second guide rod 1331. After the V-shaped push blocks 142 come into contact with the V-shaped blocks 1332, they push the V-shaped blocks 1332 to move toward the middle, overcoming the elastic force of the first spring 1333. Through the transmission of the V-shaped block 1332 slide groove and the first moving block 1322, the two rollers 1323 are synchronously separated outwards to form enough space. In order to facilitate the loading of the axle, after the axle is accurately placed between the rollers 1323, the first linear drive 141 drives the V-shaped push block 142 to return to the initial position, releasing the constraint on the V-shaped block 1332. At this time, the compressed first spring 1333 releases elastic potential energy, pushing the V-shaped block 1332 to slide toward the end of the second guide rod 1331, and the V-shaped block 1332 drives the two first moving blocks 1322 to move toward each other through the slide groove, so that the two rollers 1323 clamp the axle, thereby avoiding the friction between the axle and the roller 1323 during the loading process and reducing the wear of the roller 1323.

[0031] Reference Figure 7 and Figure 8 As shown: the wheel feeding 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 the second turntable 22 is coaxially arranged with the fixed shaft 21; the plurality of second self-clamping structures 23 are arranged on the second turntable 22 at equal intervals, and the second self-clamping structures 23 are used to keep the wheel clamped and fixed.

[0032] After the second self-clamping structure 23 clamps and fixes the wheel, the second turntable 22 starts to rotate around the axis of the fixed shaft 21. At this time, the first turntable 12 of the axle feeding mechanism 1 is also operating synchronously. When the first turntable 12 transports the axle to between the two wheel feeding mechanisms 2, the second turntable 22 transports the second self-clamping structure 23 holding the wheel to the end of the axle. Then, the press-fitting drive mechanism 3 is started, driving the wheels on the two wheel feeding mechanisms 2 to move toward the axle at the same time, and a stable connection between the wheel and the axle is achieved through interference fit and other methods. The connection is completed. After completion, the second self-clamping structure 23 releases its grip on the wheel, and the press-fitting drive mechanism 3 drives the two wheel supply mechanisms 2 away from each other. Subsequently, the first turntable 12 rotates to transfer the wheels and axles that have been press-fitted, and at the same time, the axles that have not been press-fitted are transported to between the two wheel supply mechanisms 2. The second turntable 22 also moves synchronously to transport the next second self-clamping structure 23 holding the wheel to one end of the axle, preparing for the next round of press-fitting. Through the coordinated operation of the first turntable 12 and the second turntable 22, continuous press-fitting of axles and wheels is achieved.

[0033] 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.

[0034] When the wheel is clamped, the side of the wheel is first tightly abutted against the limit plate 232 to provide a reference surface for wheel positioning. Subsequently, the self-clamping assembly 233 clamps the wheel from all sides of the wheel. Since the self-clamping assembly 233 applies the clamping force evenly, the position of each wheel fixed on the limit plate 232 is exactly the same, which ensures the accuracy of the wheel when it is subsequently docked with the axle. Then, 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 docking with the axle, the pressing drive mechanism 3 is started to drive the two wheel feeding mechanisms 2 closer to each other. At this time, the limit plate 232 acts as a force transmitting component to apply a force toward the axle to the wheel. In this process, the pressure on the wheel is evenly distributed to the entire surface in contact with the limit plate 232, avoiding the situation of excessive local force, thereby effectively preventing the wheel from being deformed due to local stress concentration during the press-fitting process.

[0035] 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 set on the connecting rod 231, and a plurality of driving arms 2332 are rotatably connected to the connecting ring 2331, and one end of the driving arm 2332 is rotatably connected to an L-shaped clamp 2333, and the middle part of the L-shaped clamp 2333 is axially connected to the limit plate 232; the two ends of the second spring 2334 are respectively abutted against the end of the connecting ring 2331 and the connecting rod 231.

[0036] Before preparing to clamp the wheel, multiple L-shaped clamps 2333 are in an unfolded state, forming an open space, which makes it convenient for the wheel to be placed in the middle of the multiple L-shaped clamps 2333. When the wheel is placed in place, the compressed second spring 2334 releases its elastic potential energy, pushing the connecting ring 2331 to move toward the end of the connecting rod 231. During the movement, the connecting ring 2331 converts its own linear motion into rotational motion of the L-shaped clamp 2333 through multiple driving arms 2332. The L-shaped clamp 2333 rotates around its axial connection with the limit plate 232, gradually retracts and tightly abuts the circumferential surface of the wheel. At the same time, the second spring 2334 continuously applies thrust, so that the L-shaped clamp 2333 always maintains the clamping force on the wheel, thereby ensuring that the wheel is firmly clamped during the process of the second turntable 22 driving the wheel to rotate.

[0037] Reference Figure 8 and Figure 11As shown: the wheel feeding mechanism 2 also includes a second opening structure 24, which is arranged on the top of the fixed shaft 21, the second opening structure 24 corresponds to the two second self-clamping structures 23, and the second opening structure 24 is used to apply a force to the connecting ring 2331 toward the fixed shaft 21.

[0038] Specifically, the second opening structure 24 includes a third guide rod 241, two compression assemblies 242 and a synchronous drive assembly 243. The middle part of the third guide rod 241 is fixedly connected to the top of the fixed shaft 21. The two compression assemblies 242 are respectively arranged at both ends of the third guide rod 241. The compression assembly 242 includes a sleeve 2421 and a baffle 2422. The sleeve 2421 is slidingly connected to the third guide rod 241. The baffle 2422 is fixedly connected to the connecting ring 2331. The synchronous drive assembly 243 includes a second linear driver 2431 and two connecting arms 2432. One end of the two connecting arms 2432 is axially connected to the output end of the second linear driver 2431, and the other ends of the two connecting arms 2432 are respectively axially connected to the two sleeves 2421.

[0039] The two second self-clamping structures 23 corresponding to the second opening structure 24 are respectively at the station for docking with the axle and the station for loading the wheel. When the wheel at the station for docking with the axle completes the connection with the axle, the second opening structure 24 is started, and the second linear drive 2431 outputs a force to drive the two connecting arms 2432 to retract and move closer to each other. The connecting arm 2432 pulls the sliding sleeve 2421 connected to its shaft, so that the two sliding sleeves 2421 move closer to each other along the third guide rod 241, and the sliding sleeve 2421 drives the connecting ring 2331 in the second self-clamping structure 23 through the baffle 2422, so that the connecting ring 2331 moves toward The middle part of the second turntable 22 moves, and during the movement of the connecting ring 2331, the multiple L-shaped clamps 2333 are rotated and expanded around the axial connection with the limit plate 232 through the transmission of the driving arm 2332, and the originally clamped wheel loses its constraint, realizing the unloading of the second self-clamping structure 23. At the same time, the second self-clamping structure 23 at the wheel loading station also has the same linkage effect, and the L-shaped clamps 2333 are synchronously expanded. After the press-fitting drive mechanism 3 drives the two wheel feeding mechanisms 2 away from each other, the wheel loading is carried out, thereby realizing the synchronous control of the loading and unloading of the second self-clamping structure 23 and simplifying the control steps.

[0040] A multi-station collaborative automatic pressing and assembling method for a toy car is applied to the above-mentioned multi-station collaborative automatic pressing and assembling equipment for a toy car, and is characterized by comprising the following steps: S1, when the bearing structure 13 is rotated to the upper 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; S2. After the wheel axle enters the positioning wheel assembly 132, the first self-clamping structure 133 drives the positioning wheel assembly 132 to clamp the wheel axle, and the first rotating disk 12 drives the wheel axle to rotate between the two wheel supply mechanisms 2; S3, the second turntable 22 in the wheel supply mechanism 2 rotates the wheel to one end of the axle; S4, the press-fitting drive mechanism 3 drives the two wheel supply mechanisms 2 to move closer to each other, so that the two wheels are plugged into the axle; S5, the second opening and closing structure controls the second self-clamping structure 23 to release the wheel, and at the same time the press-fitting drive mechanism 3 drives the two vehicle supply mechanisms away from each other; S6. When the first turntable 12 drives the press-fitted wheel and axle to rotate to the lowest end, the first opening structure 14 drives the first self-clamping structure 133 to release the press-fitted wheel and axle.
