Description

Technical Field

[0001] The present invention relates to the technical field of toy processing equipment, and more particularly to an automatic assembly device for a toy car wheel system and an assembly method thereof. Background Art

[0002] The body, wheels, and axle are the primary components of a toy car. The wheels and axle form the wheel system of a toy car. The wheels are located on either side of the body. During assembly, the wheels are connected to the body through the axle. Manual material selection and assembly are the traditional methods for selecting and assembling the wheel system. The wheels and axle are stored on separate trays. An operator selects the required number of wheels and axle from the trays and then assembles them. The assembly process is a two-step process: first, the wheels and axle are installed on one side of the body, followed by the wheels and axle on the other side. After installation of one side, the body needs to be flipped over for installation on the other side. During wheel assembly, the wheels must first be placed on the body, and then the axle must be pressed into the wheel and body. Consequently, the assembly process for a toy car wheel system is complex and time-consuming when performed manually, resulting in low efficiency. Furthermore, the long hours of labor can easily fatigue the operator, impacting assembly quality.

[0003] In this regard, the Chinese patent publication number CN106378626A, entitled "An Automatic Assembly System for Intelligent Toy Cars", discloses an automatic assembly system for toy cars for replacing manual assembly. The system comprises a wheel assembly mechanism, a wheel feeding unit is provided on the wheel assembly mechanism, the discharge end of the wheel feeding unit is connected to the wheel pressing unit, the wheel assembly mechanism also comprises an axle feeding unit, the discharge end of the axle feeding unit is connected to the wheel pressing unit, the assembly system also comprises a whole vehicle assembly mechanism, the feed axle end of the whole vehicle assembly mechanism is connected to the wheel pressing unit, and the wheel assembly mechanism further comprises an axle feeding unit. The discharging end of the wheel assembly mechanism is connected, the whole vehicle assembly mechanism includes a whole vehicle assembly unit, the upper part of the whole vehicle assembly unit is provided with a chassis feeding unit and a shell feeding unit, the discharging port of the wheel crimping unit is connected with the feeding port of the whole vehicle assembly unit, the wheel feeding unit includes a vibrating material tray, the vibrating material tray is provided with an inclined material guide plate, the lower end of the inclined material guide plate constitutes the discharging port, the lower part of the inclined material guide plate is provided with a tire vibrating plate, the discharging port of the tire vibrating plate is provided with a discharging pipe, the length direction of the discharging pipe is inclined, and the lower end of the discharging pipe is connected with the wheel crimping unit, The wheel crimping unit includes a first crimping head and a second crimping head, the first crimping head and the second crimping head are respectively connected to a driving mechanism, a discharge pipe is located at the front end of the first crimping head and the second crimping head, the driving mechanism drives the first crimping head and the second crimping head to move relative to or away from each other, and an axle pusher is provided between the first crimping head and the second crimping head. When assembling a toy car, the processed wheels are guided into a vibrating material tray, the vibrating material tray evenly scatters the tires into the tire vibrating tray, and the tire vibrating tray neatly guides the individual tires one by one from the discharge pipe to the space between the first and second crimping heads of the wheel crimping unit. The wheel crimping unit guides the axle to between the first and second crimping joints, and the driving mechanism drives the first and second crimping joints to move relative to each other, thereby assembling the tire to both ends of the axle and completing the assembly of the wheel assembly. After the wheel crimping unit assembles the wheel assembly, it guides it to the vehicle assembly mechanism, and the chassis feeding unit and the shell feeding unit are used to deliver the chassis and the shell to the vehicle assembly mechanism. The automatic screwdriver provided above the vehicle assembly unit is used to assemble the chassis and the shell together, thereby completing the assembly of the vehicle.

[0004] Although the toy car automatic assembly system of the above structure can reduce the workload of operators and improve the efficiency of material selection and assembly compared to manual material selection and assembly, it still has the problem that the axle components and the crimped wheel components cannot be directly assembled to the vehicle body by only using the wheel crimping unit, and the assistance of the whole vehicle assembly mechanism is required to connect the wheel assembly crimped by the wheel crimping unit with the chassis and shell of the vehicle body, which makes the entire assembly process time-consuming and the improvement of assembly efficiency is limited. At the same time, it also leads to the complexity of the overall structure. Summary of the Invention

[0016] An assembly method of the above-mentioned toy car wheel automatic assembly equipment comprises the following steps:

[0017] S1: placing the vehicle body parts, wheel parts and axle parts required for assembly into the first vibrating plate, the second vibrating plate and the third vibrating plate of the vehicle body conveying mechanism, the wheel conveying mechanism and the axle conveying mechanism in sequence;

[0018] S2: The PLC control cabinet controls the operation of the first vibrating plate of the vehicle body conveying mechanism and the transmission box of the front sliding mechanism. The first vibrating plate vibrates to convey the vehicle body parts to the front slot of the platen feeding channel. The transmission box drives the transmission belt to rotate. The transmission belt on the side close to the vehicle body conveying mechanism drives the vehicle body parts entering the front slot to move along the front slot toward the wheel conveying mechanism and axle conveying mechanism on the near side.

[0019] S3: When the vehicle body component moves to a position opposite to the piston rod of the first feeding cylinder of the front sliding mechanism, the first position sensor detects the position of the vehicle body component and feeds back the detection result to the PLC control cabinet. The PLC control cabinet controls the operation of the first feeding cylinder, and its piston rod pushes the relative vehicle body component to move to the other side of the front slot;

[0020] S4: When the vehicle body component reaches the position relative to the piston rod of the second feeding cylinder of the front sliding mechanism, it touches the pressure sensor. The pressure sensor converts the pressure signal into an electrical signal and sends it to the PLC control cabinet. The PLC control cabinet controls the operation of the second feeding cylinder, and its piston rod pushes the relative vehicle body component to move along the front slot to the relative position of another transmission belt. The transmission belt further drives the relative vehicle body component to move to the bottom of the wheel conveying mechanism and the axle conveying mechanism on the approaching side.

[0021] S5: When the vehicle body component moves to the bottom of the wheel conveying mechanism and the axle conveying mechanism close to one side of the vehicle body conveying mechanism, the second position sensor detects the position of the vehicle body component and feeds back the detection result to the PLC control cabinet, which interrupts the operation of the vehicle body conveying mechanism and the front sliding mechanism, and controls the operation of the second vibrating plate of the wheel conveying mechanism and the third vibrating plate of the axle conveying mechanism. The second vibrating plate and the third vibrating plate convey the wheel components and axle components inside to the second guide plate and the conveying pipeline. The wheel components fall into one side of the vehicle body component in two rows from the blanking port on the second guide plate, and the axle components fall into the discharge port of the holding block in two rows.

[0022] S6: The seventh position sensor on the clamping cylinder jaws of the crimping mechanism detects the position of the axle component and feeds back the detection result to the PLC control cabinet, which interrupts the operation of the wheel conveying mechanism and the axle conveying mechanism and controls the operation of the clamping cylinder to move its two clamping jaws toward each other to clamp the axle component in the slot. At the same time, the operation of the transverse cylinder is controlled to push the clamping cylinder to move above the slot on the front side of the feeding channel. The eighth position sensor on the crimping cylinder detects the position of the clamping jaws and feeds back the detection result to the PLC control cabinet, which controls the operation of the crimping cylinder to press the axle component into the wheel component and the body component through the pressing block to obtain a semi-finished toy car. Then, the clamping cylinder, the transverse cylinder and the crimping cylinder are controlled to return to their positions.

[0023] S7: The PLC control cabinet controls the operation of the front sliding mechanism again, and the transmission belt close to the side of the vehicle body conveying mechanism drives the semi-finished toy car to move toward the tipping mechanism. When it reaches the relative position with the piston rod of the first tipping cylinder, the fifth position sensor detects the position of the semi-finished toy car, and feeds back the detection result to the PLC control cabinet. The PLC control cabinet controls the operation of the first tipping cylinder to push the semi-finished toy car toward the second tipping cylinder, and through the step surface on the table, the semi-finished toy car is turned 180° into the rear slot of the feeding channel. The sixth position sensor detects the position of the semi-finished toy car, and feeds back the detection result to the PLC control cabinet. The PLC control cabinet controls the operation of the second tipping cylinder to push the semi-finished toy car in the direction perpendicular to the rear slot until it rests on the step surface of the table.

[0024] S8: The third position sensor of the rear sliding mechanism detects the position of the semi-finished toy car and feeds the detection result back to the PLC control cabinet. The PLC control cabinet controls the operation of the third feeding cylinder to drive the push plate and the paddle to rise along the guide groove, and controls the operation of the fifth feeding cylinder to drive the push plate and the paddle to move along the guide groove toward the semi-finished toy car until the paddle moves to both sides of the semi-finished toy car. Then, the fourth feeding cylinder is controlled to operate to push the third feeding cylinder, the fifth feeding cylinder, the push plate, the paddles, and the semi-finished toy car located between the paddles toward the wheel conveying mechanism and the axle conveying mechanism away from the vehicle body conveying mechanism.

[0025] S9: After the fourth position sensor of the rear sliding mechanism detects the position of the semi-finished toy car, the detection result is fed back to the PLC control cabinet, and the PLC control cabinet interrupts the operation of the fourth feeding cylinder and controls the operation of the wheel conveying mechanism and the axle conveying mechanism to complete the installation of the wheel components and axle components on the other side of the semi-finished toy car in the same way to obtain the finished toy car. The fourth feeding cylinder is operated to push the finished toy car out of the feeding channel.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] During the assembly process of the toy car wheels by the automatic assembly equipment of the toy car wheel system of the present invention, the wheel components and the axle components can be directly pressed onto the body components when the body components are conveyed in the feeding channel. There is no need to first assemble the wheel components and the axle components and then assemble them with the body components, so that the assembly process of the toy car wheel system is greatly simplified, thereby reducing the time spent on assembling the toy car wheel system and significantly improving the assembly efficiency. At the same time, there is no need to add an additional vehicle assembly mechanism, so that the overall structure of the equipment of the present invention is also simplified, and it also has the advantage of lower manufacturing cost.

[0044] like Figures 1 to 3 as well as Figure 11As shown, the present invention relates to an automatic assembly device for a wheel system of a toy car, the device comprising a table 1, a body conveying mechanism 2, a wheel conveying mechanism 3, an axle conveying mechanism 4, a front sliding mechanism 5, a rear sliding mechanism 6, a turning mechanism 7 and a pressing mechanism 8, the table 1 is a place for assembling the wheel system of a toy car finished product A1, the body conveying mechanism 2, the wheel conveying mechanism 3 and the axle conveying mechanism 4 are respectively used to convey the body component a1, the wheel component a2 and the axle component a3 required for assembly to the table 1, the front sliding mechanism 5 and the rear sliding mechanism 6 are used to drive the body component a1, the toy car semi-finished product A2 obtained during the assembly process, and the assembled toy car finished product A1 to move on the table 1, the turning mechanism 7 is used to drive the toy car semi-finished product A2 to be turned over after the wheel component a2 and the axle component a3 on one side of the body component a1 are assembled, and the pressing mechanism 8 is used to grab and move the axle component a3 conveyed to the table 1, and press-connect it to the wheel component a2 and the body component a1;

[0045] The above-mentioned platform 1 has a feeding channel, and the finished toy car is assembled in the feeding channel. The feeding channel extends from one side of the platform 1 to the other side and penetrates the two end surfaces of the platform 1. The body conveying mechanism 2, the wheel conveying mechanism 3 and the axle conveying mechanism 4 are all arranged on one side of the platform 1. The body conveying mechanism 2 is opposite to the entrance of the feeding channel. The body part a1 conveyed outward by the body conveying mechanism 2 can directly enter the feeding channel. The wheel conveying mechanism 3 extends to the top of the feeding channel, and the axle conveying mechanism 4 extends to a position above the feeding channel. The wheel component a2 transported by the wheel conveying mechanism 3 is opposite to the feeding channel, and the wheel component a2 transported outward can directly fall into the feeding channel for assembly. The axle component a3 transported by the axle conveying mechanism 4 is staggered with the feeding channel. In the present invention, the wheel conveying mechanism 3 and the axle conveying mechanism 4 are each configured with two groups. The two groups of wheel conveying mechanisms 3 and axle conveying mechanisms 4 are respectively used for assembling the wheel components a2 and axle components a3 on both sides of the toy car. One group of axle conveying mechanisms 4 transports the long axle component a3, and the other axle conveying mechanism transports the long axle component a3. The mechanism 4 conveys the short axle component a3, the front sliding mechanism 5, the rear sliding mechanism 6, the turning mechanism 7 and the pressing mechanism 8 are all arranged on the table 1, the front sliding mechanism 5 and the rear sliding mechanism 6 are located on the side of the feeding channel and are spaced apart, and the front sliding mechanism 5 is opposite to the wheel conveying mechanism 3 and the axle conveying mechanism 4 on one side, and the rear sliding mechanism 6 is opposite to the wheel conveying mechanism 3 and the axle conveying mechanism 4 on the other side, the turning mechanism 7 is located between the front sliding mechanism 5 and the rear sliding mechanism 6, and is opposite to the feeding channel, and the pressing mechanism 8 is opposite to the front sliding mechanism 5 and the rear sliding mechanism 6. There are two groups of sample configurations, and the two pressing mechanisms 8 correspond to the front sliding mechanism 5 and the rear sliding mechanism 6 opposite to the front sliding mechanism 5 and the rear sliding mechanism 6. After the axle component a3 is conveyed outward, it is grabbed by the pressing mechanism 8 and moved to the feeding channel, and simultaneously pressed to the wheel component a2 and the body component a1 to complete the assembly of the axle component a3. The body conveying mechanism 2, the wheel conveying mechanism 3, the axle conveying mechanism 4, the front sliding mechanism 5, the rear sliding mechanism 6, the turning mechanism 7 and the pressing mechanism 8 are all controlled by the PLC control cabinet;

[0046] During assembly, the PLC control cabinet first controls the vehicle body conveying mechanism 2 to operate and convey the vehicle body component a1 to the feeding channel. The front side sliding mechanism 5 drives the vehicle body component a1 entering the feeding channel to move toward the wheel conveying mechanism 3 and the axle conveying mechanism 4 opposite thereto under the control of the PLC control cabinet. When the vehicle body component a1 reaches under the wheel conveying mechanism 3 and the axle conveying mechanism 4, the wheel conveying mechanism 3 and the axle conveying mechanism 4 respectively place the wheel component a2 on the vehicle body component a1 on one side under the control of the PLC control cabinet, and convey the long axle component a3 toward the platen 1. The crimping structure is under the control of the PLC control cabinet. Under the control of the PLC control cabinet, the long axle component a3 is grabbed and moved into the feeding channel until it is moved to a position relative to the shaft hole on the wheel component a2 and the body component a1 in the feeding channel, and then the long axle is pressed tightly between the wheel component a2 and the body component a1 to obtain the toy car semi-finished product A2. After the crimping is completed, the front side sliding mechanism 5 drives the toy car semi-finished product A2 to move along the feeding channel to the turning mechanism 7. The turning mechanism 7 turns the toy car semi-finished product A2 180 degrees under the control of the PLC control cabinet. After the turning is completed, the rear side sliding mechanism 6 drives the toy car semi-finished product A2 under the control of the PLC control cabinet. Continue to transport the semi-finished toy car A2 along the feeding channel to the wheel conveying mechanism 3 and the axle conveying mechanism 4 on the other side. When the semi-finished toy car A2 reaches the bottom of the wheel conveying mechanism 3 and the axle conveying mechanism 4 on this side, it is controlled by the PLC control cabinet to place the wheel component a2 on the opposite body component a1, and transport the short axle component a3 toward the platen 1. After that, the PLC control cabinet controls the crimping structure on this side to move the short axle into the feeding channel in the same way and crimp it to the wheel component a2 and the body component a1 to obtain the finished toy car A1. After that, it is driven by the rear sliding mechanism 6 along the feeding channel. Transported outward, during the entire toy car wheel assembly process, the wheel component a2 and the axle component a3 can be directly pressed onto the body component a1 when the body component a1 is transported in the feeding channel. There is no need to first assemble the wheel component a2 and the axle component a3 and then assemble them with the body component a1, which greatly simplifies the toy car wheel system assembly process, thereby reducing the time spent on toy car wheel system assembly and significantly improving assembly efficiency. At the same time, there is no need to add additional vehicle assembly mechanisms, which simplifies the overall structure of the equipment of the present invention, and therefore has the advantage of lower manufacturing costs.

The front slot 102 and the rear slot 103 are respectively located on both sides of the step surface 101. The front slot 102 and the rear slot 103 are staggered and independent of each other. It can be understood that there is a height difference between the front slot 102 and the rear slot 103, and the height difference on both sides of the rear slot 103 is different.

In the present invention, the two transmission boxes 501 are arranged on the same side of the front slot 102. The two transmission boxes 501 are spaced and staggered, that is, the distance from the front slot 102 is not equal. The transmission box 501 close to the vehicle body conveying mechanism 2 is farther away from the front slot 102 than the other transmission box 501. The transmission box 501 away from the vehicle body conveying mechanism 2 is located below the wheel conveying mechanism 3.

It should be mentioned that the transmission box 501 in the present invention is internally provided with a motor and a gear set, and the transmission wheel is driven to rotate by the motor. The transmission box 501 can be selected from the common transmission box 501 models on the market. The transmission wheel rotates to transmit the transmission belt 504. After the body part a1 enters the front slot 102 of the feeding channel and the semi-finished toy car A2 is assembled, they are both located on the corresponding front side sliding mechanism 5 transmission belt 504 side.

The first feeding cylinder 505 is arranged between the two transmission boxes 501, and the piston rod of the first feeding cylinder 505 is opposite to the feeding channel. The first position sensor is arranged at the proximity position of the transmission box 501 and the first feeding cylinder 505 on the side away from the body conveying mechanism 2. When the body part a1 moves toward the first feeding cylinder 505, after reaching the relative position with the piston rod of the first feeding cylinder 505, the first position sensor detects the body part a1. At this time, the PLC control cabinet controls The first feeding cylinder 505 is controlled to operate, and the piston rod of the first feeding cylinder 505 pushes the vehicle body component a1 opposite to it to move to the other side of the front slot 102. The second position sensor is arranged under the wheel conveying mechanism 3 and the axle conveying mechanism 4 close to the transmission box 501.

At this time, the PLC control cabinet interrupts the operation of the transmission box 501 of the front sliding mechanism 5, stops the transmission of the two transmission belts 504, and thus keeps the vehicle body component a1 under the wheel conveying mechanism 3 and the axle conveying mechanism 4 to assemble the wheel component a2 and the axle component a3 on one side.

[0053] like Figure 8As shown, the front sliding mechanism 5 also includes a second feeding cylinder 506, a support plate 507 and a pressure sensor.

The piston rod of the second feeding cylinder 506 can be opposite to the piston rod of the first feeding cylinder 505 when extended. The support plate 507 is provided in the feeding channel on one side of the second feeding cylinder 506 and is opposite to the transmission belt 504 close to the vehicle body conveying mechanism 2, thereby isolating the second feeding cylinder 506 from the front side slot 102. The internal space of the front side slot 102 is formed into a staggered Z shape through the support plate 507. The first feeding cylinder 505 is located in the Z shape. In the middle position of the Z-shaped front slot 102, the pressure sensor is arranged on the other side of the feeding channel opposite to the piston rod of the first feeding cylinder 505 and the piston rod of the second feeding cylinder 506, that is, on the other side of the middle position of the Z-shaped front slot 102. When the piston rod of the first feeding cylinder 505 pushes the body part a1 opposite to it to move to the other side of the front slot 102, after the body part a1 touches the pressure sensor, the PLC control cabinet controls the operation of the second feeding cylinder 506, and its piston rod pushes the body part a1 to move to the transmission belt 504 on the other side, and then the transmission belt 504 drives it to move to the bottom of the wheel conveying mechanism 3 and the axle conveying mechanism 4 on the approaching side.

[0054] like Figures 11 to 12As shown, the rear sliding mechanism 6 includes a third feeding cylinder 601, a clamping block 602, a fourth feeding cylinder 603, a fifth feeding cylinder 604, a plurality of limit cylinders 605, a push plate 606, a plurality of paddles 607, two third position sensors and a fourth position sensor, wherein a vertical plate 104 extending downward is provided below the table 1, a horizontal bar 105 is provided on one side of the vertical plate 104, and the horizontal bar 105 is arranged in a direction parallel to the rear side groove of the feeding channel, the third feeding cylinder 601 is located on one side of the vertical plate 104, and the clamping block 602 is provided on the third feeding cylinder 601, which is concave in shape, and the clamping block 602 is clamped on the horizontal bar 105 through the notch and is slidably connected to it, thereby supporting the third feeding cylinder 601 through the horizontal bar 105, and it can reciprocate along the horizontal bar 1 05 sliding, it should be mentioned that the third feeding cylinder 601 is arranged with its piston rod facing upward, the fourth feeding cylinder 603 is arranged on the vertical plate 104, and its piston rod is connected to the third feeding cylinder 601, so that when the fourth feeding cylinder 603 is running, it can push the third feeding cylinder 601 to slide along the cross bar 105, the fifth feeding cylinder 604 is connected to the piston rod of the third feeding cylinder 601, and the push plate 606 is arranged on the piston rod of the fifth feeding cylinder 604, and each paddle 607 is arranged at one end of the push plate 606 above the table 1, and a guide groove 106 opposite to the push plate 606 is opened on the table 1, and the guide groove 106 is located on one side of the feeding channel, and one end of the paddle 607 passes through the guide groove 106 to the top of the table 1 and extends to the back of the feeding channel. In the side slots 103, the space in the rear slots 103 between adjacent paddles 607 is used for the entry of the finished toy car A1. A return slot opposite to the paddle 607 and connected to the guide slot 106 is provided on the table 1. It can be understood that when the piston rod of the fourth feeding cylinder 603 is in the initial state, that is, the third feeding cylinder 601, the fifth feeding cylinder 604, the push plate 606 and the paddle 607 are opposite to the paddle 607 in the initial state, when the finished toy car A1 enters, the PLC control cabinet controls the operation of the fourth feeding cylinder 603, and the movement of its piston rod pushes the third feeding cylinder 601 to slide along the cross bar 105. When the third feeding cylinder 601 slides, it drives the fifth feeding cylinder 604, the push plate 606 and the paddle 607 to slide. Then, the toy car finished product A1 in the rear slot 103 can be pushed to the other side by the moving paddle 607 to complete the transportation. When the toy car finished product A1 is about to enter the rear slot 103, the PLC control cabinet controls the piston rod of the fourth feeding cylinder 603 to return, driving the third feeding cylinder 601, the fifth feeding cylinder 604, the push plate 606 and the paddle 607 to move to the initial position. At this time, the paddle 607 is opposite to the corresponding return slot, and then the PLC control cabinet controls the third feeding cylinder 601 to operate, and its piston rod extends outward to drive the fifth feeding cylinder 604, the push plate 606 and each paddle 607 to lift upward until the height of the paddle 607 exceeds the height of the toy car finished product A1. After that, the PLC control cabinet controls the fifth feeding cylinder 604 to operate.The piston rod moves away from the rear slot 103 until the push plate 606 and the paddle 607 move into the return slot, so that the paddle 607 is disengaged from the rear slot 103. At this time, the finished toy car A1 can enter the rear slot 103. When the finished toy car A1 is to be pushed to move, the PLC control cabinet controls the fifth feeding cylinder 604 to operate, and the fifth feeding cylinder 604 drives the push plate 606 and the paddle 607 to move back, so that the paddle 607 can be inserted into the finished toy car A1. 1, the paddle 607 can drive the toy car finished product A1 to move when the fourth feeding cylinder 603 is driven. In addition, a limit plate opposite to the paddle 607 is provided on the platform 1 on one side of the feeding channel.

The two third Position sensors are located on one side of the rear slot 103 of the feeding channel near the front sliding mechanism 5 and on the other side of the rear slot 103. When the finished toy car A1 enters the rear slot 103, the third position sensor near the side of the vehicle body conveying mechanism 2 can detect the position of the finished toy car A1, and then the PLC control cabinet controls the operation of the rear sliding mechanism 6. When the finished toy car A1 is pushed out, another third position sensor detects the position of the paddle 607, and the PLC control cabinet controls the return of the third feeding cylinder 601, the fourth feeding cylinder 603, and the fifth feeding cylinder 604. The fourth position sensor is located below the wheel conveying mechanism 3 and the axle conveying mechanism 4 away from the vehicle body conveying mechanism 2, and is used to detect the position of the semi-finished toy car A2. When the semi-finished toy car A2 moves below the wheel conveying mechanism 3 and the axle conveying mechanism 4 away from the vehicle body conveying mechanism 2, the PLC control cabinet interrupts the operation of the fourth feeding cylinder 603.

The crimping cylinder 804 is located above the feeding channel and is opposite to the clamping cylinder 801. The pressing block 805 is arranged at the lower end of the piston rod of the crimping cylinder 804. The crimping cylinder 804 is used to clamp the axle component a3. When the cylinder 801 controls the grasped axle component a3 to move to the bottom thereof, the axle component a3 is pressed into the wheel component a2 and the vehicle body component a1 in the feeding channel below by the pressure block 805 through the movement of its piston rod. The seventh position sensor is provided on the side of any clamping jaw 802 on the clamping cylinder 801 close to the card slot 802a, and is used to detect the position of the axle component a3 relative to the card slot 802a.
