Description

Technical Field

[0001] This utility model relates to the field of automatic wheel assembly technology, and in particular to a wheel assembly device. Background Technology

[0002] Traditional wheel and support component assembly relies heavily on manual operation, resulting in low efficiency, high cost, and poor product consistency. In existing processes, workers must manually perform steps such as wheel orientation identification, bearing positioning, and adjusting the spacing between bearing rings. Due to the precision structure of wheel components and the need for multiple specification variations, manual operation is prone to problems such as misalignment and insufficient positioning accuracy, leading to increased rework rates. Especially when dealing with multi-variety production, repeated adjustments to tooling fixtures and retraining of operators are necessary, resulting in long changeover cycles and low flexibility. While existing semi-automatic equipment can mechanize some processes, key steps still rely on manual intervention, limiting the overall efficiency improvement. Furthermore, traditional assembly lines require multiple operators, leading to high labor costs and issues such as high labor intensity and safety hazards in the working environment. Therefore, we provide a wheel assembly equipment to address these problems. Utility Model Content

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0040] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figure 1 — Figure 19 The example shown.

[0042] Please see Figure 18 and Figure 19 As shown, the wheel to be assembled in this application mainly includes a first bearing a, a spacer ring b, a second bearing c, a roller d, a wheel axle e, and a bolt f. Roller d has a central hole at its center, spacer ring b is hollow, and wheel axle e has a threaded hole at the center of one end. The first bearing a, spacer ring b, and second bearing c are sequentially arranged in the central hole. Wheel axle e is located in the through hole formed by the inner rings of the first bearing a, spacer ring b, and second bearing c. Finally, the bolt f is screwed into the threaded hole of wheel axle e to fix wheel axle e to the first bearing a, thereby completing the assembly of the entire wheel.

[0043] It should be noted that in this embodiment, the first bearing and the second bearing are identical in model and size. Therefore, their inner and outer rings are also the same size. Specifically, the inner ring diameters of the first and second bearings should be the same as the inner diameter of the spacer ring. Furthermore, one end of the spacer ring abuts against the inner ring of the first bearing, and the other end abuts against the inner ring of the second bearing, thus facilitating the passage of the axle. Even further, the axle has a contact surface. During installation, when the axle passes through the first bearing and the spacer ring to the second bearing, the contact surface abuts against the inner ring of the first bearing. After being bolted to the axle, it is fixed to the second bearing.

[0044] To complete the assembly of the aforementioned components, this application provides a wheel assembly device. The wheel assembly device includes a turntable device 100, which includes a disc body 110. Multiple fixtures 120 are spaced apart on the disc body 110, and each fixture 120 has a temporary storage rod 130 on one side. A first feeding device 200, a second feeding device 300, a third feeding pressing device 400, and a discharge conveying device 500 are sequentially arranged along the rotation direction on the outer circumference of the disc body 110. The first feeding device 200 is used to sequentially transport a first bearing and a spacer ring onto the fixture 120, and to transport a second bearing onto the temporary storage rod 130. The second feeding device 300 is used to transport a roller onto the fixture 120. The third feeding pressing device 400 is used to install the second bearing into the center hole of the roller. The discharge conveying device 500 is used for… The material is transported and unloaded by rollers equipped with a first bearing, a second bearing, and a spacer ring, and the rollers are then mounted onto axles. A clamping and unloading conveying device 900 is provided at the unloading position of the unloading conveying device 500. The clamping and unloading conveying device 900 has a conveyor line and at least one clamping and fixing component 920 for clamping axles. A fourth feeding device 700 is provided at the feeding end of the clamping and fixing component 920, providing axles to the clamping and fixing component 920. A transport and transfer device 600 is provided on one side of the clamping and fixing component 920, used to transport the rollers with axles to the conveyor line. A screwing device 800 is provided on the other side of the clamping and fixing component 920, used to screw bolts onto the axles for fixing them.

[0045] See Figure 1 , Figure 2 as well as Figure 3As shown, during wheel assembly, the first bearing and spacer ring are first stacked from bottom to top onto the fixture 120 via the first loading device 200. Next, the second bearing is placed onto the temporary storage rod 130 via the first loading device 200, thus completing the loading of the first bearing, spacer ring, and second bearing. Then, the disc 110 rotates the fixture 120 containing the first bearing and spacer ring to the unloading position of the second loading device 300. The second loading device 300 then places the roller onto the temporary storage rod 130. At this point, the first bearing and spacer ring are located at the center hole of the roller. Next, the disc 110... The roller is rotated to the position of the third feeding and pressing device 400. The third feeding and pressing device 400 transports the second bearing on the temporary storage rod 130 to the fixture 120. At this time, the fixture 120 is located at the position of the center hole of the roller. At this time, the fixed-distance ring is located between the first bearing and the second bearing. The third feeding and pressing device 400 presses down towards the position of the center hole of the roller, so that the outer rings of the first bearing and the second bearing are interference-fitted with the inner wall of the center hole of the roller, thereby completing the installation of the first bearing and the second bearing. As the disc 110 rotates, the roller with the first bearing, the fixed-distance ring and the second bearing installed is rotated to the position of the unloading and conveying device 500.

[0046] Please continue reading. Figure 1 , Figure 2 as well as Figure 3 The fourth feeding device 700 transports the axle to the clamping and fixing component 920 of the clamping and unloading conveying device 900. The clamping and fixing component 920 clamps and fixes the axle. The unloading and conveying device 500 transports the roller to the clamping and fixing component 920. The axle passes through the first bearing and the spacer ring to the second bearing. At this time, the abutting surface of the axle abuts against the inner ring of the first bearing. Then, the bolt is screwed onto the axle by the screwing device 800 to fix the axle to the inner ring of the second bearing, thereby completing the assembly of the entire wheel.

[0047] Please see Figure 4 As shown, in this embodiment, the fixture 120 includes a base plate 121 mounted on the disc body 110. A fixing post 122 is fixedly mounted on the upper surface of the base plate 121. A first sleeve post 1221 is provided on the top of the fixing post 122. The diameter of the first sleeve post 1221 is smaller than that of the fixing post 122. A stepped surface is formed between the first sleeve post 1221 and the fixing post 122. The fixing post 122 and the first sleeve post 1221 are integrally formed. A sliding disk 124 is slidably mounted on the fixing post 122. A compression spring 125 is sleeved on the outer surface of the guide post 123. One end of the compression spring 125 abuts against the base plate 121, and the other end of the compression spring 125 is grounded to the sliding disk 124. A driven disk 126 is fixedly mounted on the upper surface of the sliding disk 124. A placement groove 127 is opened at the center of the upper surface of the driven disk 126.

[0048] It should be noted that the diameter of the first set of setting column 1221 is smaller than the inner diameter of the first bearing, the spacer ring and the second bearing, the outer diameter of the fixing column 122 is larger than the inner diameter of the first bearing and the second bearing, and further, the diameter of the placement groove 127 is larger than the outer diameter of the first bearing and the second bearing.

[0049] When the first feeding device 200 feeds and transports the first bearing, the spacer ring and the second bearing, the first bearing and the spacer ring are fitted onto the outer surface of the first sleeve column 1221, and the first bearing is abutted by the stepped surface to prevent it from falling further downward.

[0050] The temporary storage rod 130 includes a fixed rod 131 fixedly installed on the disc body 110. The top of the fixed rod 131 has a second sleeve post 132. The fixed rod 131 and the second sleeve post 132 are integrally formed. The outer diameter of the fixed rod 131 is larger than the outer diameter of the second sleeve post 132. For this reason, a stepped surface is formed between the fixed rod 131 and the second sleeve post 132. It should be noted that the diameter of the second sleeve post 132 is smaller than the inner ring of the second bearing, so that the second bearing can be fitted onto the second sleeve post 132.

[0051] The first feeding device 200 includes a first vibratory feeder assembly 210 and a second vibratory feeder assembly 220. A robot arm 230 is provided on one side of the first vibratory feeder assembly 210. A first gripper cylinder 240 is installed on the moving end of the robot arm 230. The first vibratory feeder assembly 210 provides a first bearing and a second bearing for the first gripper cylinder 240, and the second vibratory feeder assembly 220 provides a fixed-distance ring for the first gripper cylinder 240.

[0052] See Figure 6 As shown, the first vibratory feeder assembly 210 arranges the randomly arranged first and second bearings into an ordered output. It should be noted that the first and second bearings have the same specifications. Therefore, both the first and second bearings are provided by the first vibratory feeder assembly 210. The second vibratory feeder assembly 220 provides a spacer ring. In order to place the first bearing and the spacer ring on the first mounting post 1221 and to mount the second bearing on the second mounting post 132, a robot arm 230 is set on one side of the first vibratory feeder assembly 210. The moving end of the robot arm 230 is equipped with a first gripper cylinder 240. The first gripper cylinder 240 clamps the first bearing, the second bearing, and the spacer ring. Finally, the robot arm 230 moves and places the clamped first bearing, the second bearing, and the spacer ring.

[0053] The second feeding device 300 includes a rotating disk 310, on which a plurality of columns 320 are evenly spaced. Each column 320 is stacked with a plurality of rollers. A first two-axis transfer module 330 is provided on one side of the rotating disk 310. The first two-axis transfer module 330 drives a driven plate mounted on its moving end. A second gripper cylinder 340 is fixedly mounted on the driven plate. A clamping plate 350 is mounted on the gripper of the second gripper cylinder 340.

[0054] See Figure 7 As shown, the first two-axis transfer module 330 can drive the second gripper cylinder 340 to move in both the horizontal and vertical directions, thereby enabling the clamping and transport of rollers at different heights. Specifically, when it is necessary to clamp and transport the rollers, the first two-axis transfer module 330 first moves the second gripper cylinder 340 to the position of the roller, and then the second gripper cylinder 340 drives the two clamping plates 350 to move closer to each other, thereby clamping the rollers. Finally, the first two-axis transfer module 330 transports the rollers to the position of the fixture 120. It should be noted that at this time, the inner ring of the roller is fitted onto the first set of mounting posts 1221.

[0055] Please continue reading. Figure 7 As shown, in order to continuously supply rollers to the second gripper cylinder 340, the rotating disk 310 is configured to be rotatable, and the column 320 has multiple rollers evenly spaced on the rotating disk 310. The column 320 has multiple rollers stacked from top to bottom. When the roller on one of the columns 320 has finished loading, the rotating disk 310 drives the column 320 to rotate, so that the column 320 with rollers moves to the loading position of the second gripper cylinder 340, thereby clamping and feeding the second gripper cylinder 340 without stopping the machine.

[0056] For example, the first two-axis transfer module 330 can be assembled from two motor lead screw linear modules, thereby enabling the second gripper cylinder 340 to move in two dimensions.

[0057] A front and back detection component 370 is fixedly installed on the driven plate. The front and back detection component 370 includes a fixing block 371 installed on the driven plate. A first slide rod 372 is slidably installed in the through hole of the fixing block 371. A first abutting plate 373 is fixedly provided on the outer surface of the first slide rod 372. The first abutting plate 373 is located below the fixing block 371. A first compression spring 374 is sleeved on the outer surface of the first slide rod 372. The first compression spring 374 is located between the first abutting plate 373 and the fixing block 371. A first photoelectric sensor 375 is also fixedly installed on the driven plate. When the first slide rod 372 moves against the elastic force of the first compression spring 374, the end of the first slide rod 372 is sensed by the first photoelectric sensor 375. A guide plate 360 ​​is provided on the transfer path of the first biaxial transfer module 330.

[0058] See Figure 8 and Figure 9 As shown, since the roller has a front and a back, it is necessary to assemble the roller with the front facing up. Specifically, in this embodiment, the front and back detection component 370 is used to detect and distinguish the front and back of the roller.

[0059] In this embodiment, one side of the roller has a boss, while the other side does not. It should be noted that the side without the boss is the front. For details, please refer to the following documentation. Figure 8 and Figure 9 As shown, after the second gripper cylinder 340 moves the clamping plate 350 to clamp the roller, if the lower end of the first slide rod 372 touches the boss and slides upward against the elastic force of the first compression spring 374, which is detected by the first photoelectric sensor 375, it means that the back of the roller is facing up (the side with the boss). Therefore, when the first two-axis transfer module 330 transfers the roller past the guide plate 360, the second gripper cylinder 340 moves the clamping plate 350 in the opposite direction to release the clamping of the roller, so that the roller is conveyed to one side of the frame or conveyor belt through the guide plate 360. Conversely, if the first slide rod 372 does not move under force after the second gripper cylinder 340 moves the clamping plate 350 to clamp the roller, it means that the front of the roller is facing up (the side without the boss). At this time, the clamped roller can be normally transported to the fixture 120 by the first two-axis transfer module 330.

[0060] The third feeding and pressing device 400 includes a second two-axis transfer module 410. A third gripper cylinder 420 is fixedly installed on the moving end of the second two-axis transfer module 410. A bracket 430 is fixedly provided on one side of the second two-axis transfer module 410. A first lifting drive component 440 is fixedly installed on the bracket 430. A pressing plate 450 and a pressing rod 460 are fixedly installed on the telescopic end of the first lifting drive component 440.

[0061] See Figure 10 As shown, when the second bearing located on the temporary storage rod 130 needs to be installed into the center hole of the roller, the fixture 120, which has the first bearing, the spacer ring, and the roller, is rotated to the position of the third feeding and pressing device 400. During installation, the third gripper cylinder 420 first drives the second two-axis transfer module 410 to the position of the temporary storage rod 130 to clamp the second bearing. Then, the second bearing is put on the first mounting column 1221. At this time, the spacer ring is located between the first bearing and the second bearing. Next, the first lifting drive component 440 is activated to drive the pressing plate 450 and the pressing rod 460 to move downward, so that the outer rings of the first bearing and the second bearing are pressed and installed with the center hole of the roller. It should be noted that the outer rings of the first bearing and the second bearing are slightly larger than the center hole of the roller. Therefore, the outer rings of the first bearing and the second bearing are interference-fitted with the center hole of the roller.

[0062] Please see Figure 4 and Figure 10 As shown, when pressed down, the pressing plate 450 presses down on the roller, and the pressing rod 460 presses down on the second bearing. Due to the downward pressure, the driven plate 126 and the sliding plate 124 slide downward against the elastic force of the compression spring 125 until the first bearing, the spacer ring, and the second bearing are installed in the center hole of the roller. After the first lifting drive 440 drives the pressing plate 450 and the pressing rod 460 to return to the initial position, the sliding plate 124 and the driven plate 126 move upward to return to the initial position under the elastic force of the compression spring 125.

[0063] In this embodiment, the third gripper cylinder 420 is formed by assembling two cylinders. Of course, the third gripper cylinder 420 can also be formed by assembling two other linear modules, which is not limited here.

[0064] The material handling device 500 includes a first linear drive 510, a second linear drive 520 is fixedly installed on the moving end of the first linear drive 510, and a gripper assembly 530 is fixedly installed on the moving end of the second linear drive 520.

[0065] Please see Figure 11 As shown, after the first bearing, the spacer ring, and the second bearing are installed on the roller, the installed roller is rotated to the loading position of the unloading and conveying device 500 via the disc body 110. Specifically, the gripper assembly 530 is moved to the roller position by the cooperation of the first linear drive member 510 and the second linear drive member 520. Then, the gripper assembly 530 clamps the roller, and finally, the roller is moved and unloaded by the cooperation of the first linear drive member 510 and the second linear drive member 520.

[0066] In this embodiment, the gripper assembly 530 is a three-jaw cylinder, which is used to grip, transport, and unload the roller.

[0067] The fourth feeding device 700 includes a third vibratory feeder assembly 710, which is used to arrange and transport randomly arranged wheel axles in an orderly manner. A carrier block 720 is fixedly provided at the discharge end of the third vibratory feeder assembly 710. A second lifting drive component 730 is provided on one side of the carrier block 720. A first rotary gripper cylinder 740 for clamping the wheel axle located in the carrier block 720 is fixedly installed at the telescopic end of the second lifting drive component 730. A third two-axis transfer module 750 is provided on one side of the second lifting drive component 730. A second rotary gripper cylinder 760 is fixedly installed at the moving end of the third two-axis transfer module 750. The second rotary gripper cylinder 760 is used to clamp the wheel axle from the first rotary gripper cylinder 740.

[0068] See Figure 13 and Figure 14 As shown, when the axle needs to be installed, it first needs to be fed by the fourth feeding device 700. Specifically, the third vibratory feeder assembly 710 arranges the disordered axles into an orderly manner until the third vibratory feeder assembly 710 conveys the arranged axles into the groove of the carrier block 720. Then, the second lifting drive component 730 drives the first rotary gripper cylinder 740 to move to the position of the carrier block 720. The first rotary gripper cylinder 740 clamps and rotates the axle. Next, the third two-axis transfer module 750 drives the second rotary gripper cylinder 760 to move to the position of the first rotary gripper cylinder 740. The second rotary gripper cylinder 760 clamps the axle held by the first rotary gripper cylinder 740. After the first rotary gripper cylinder 740 releases the grip, the axle held by the second rotary gripper cylinder 760 is placed in the position of the clamping and fixing component 920 under the transfer of the third two-axis transfer module 750, thus completing the feeding of the axle.

[0069] It should be noted that after the axle is clamped and fixed by the clamping and fixing component 920, the unloading and conveying device 500 unloads the roller to the position of the clamping and fixing component 920. Specifically, the first bearing inner ring, the spacer ring and the second bearing inner ring at the center hole position of the roller are fitted onto the axle. At this time, the end of the axle is located at the position of the second bearing inner ring, and the threaded hole of the axle is facing upward, waiting for the bolt to be screwed into the threaded hole.

[0070] Please continue reading. Figure 13As shown, in order to determine whether there is a wheel axle in the groove of the carrier block 720, a positioning sensing component 770 is provided on one side of the carrier block 720 for detection. Specifically, the positioning sensing component 770 includes a mounting block 771 located on one side of the carrier block 720. A second slide rod 772 is slidably installed in the inner hole of the mounting block 771. One end of the second slide rod 772 extends into the groove of the carrier block 720, and the other end extends to one side of the mounting block 771. A second photoelectric sensor 775 is fixedly installed on one side of the mounting block 771. The second photoelectric sensor 775 is used to detect the second slide rod 772. A second abutment plate 773 is fixedly provided on the outer surface of the mounting block 771. A second compression spring 774 is sleeved on the outer surface of the 72. The second compression spring 774 is located between the second abutment plate 773 and the mounting block 771. It can be understood that when there is an axle in the groove of the carrier block 720, the third vibrating plate assembly 710 continues to deliver the axle. Under the action of the force delivered by the axle, the second slide rod 772 moves towards the second photoelectric sensor 775, overcoming the elastic force of the second compression spring 774. If the second photoelectric sensor 775 detects the presence of the second slide rod 772, it indicates that there is an axle in the groove of the carrier block 720. Conversely, if the second photoelectric sensor 775 does not detect the presence of the second slide rod 772, it indicates that there is no axle in the groove of the carrier block 720.

[0071] The transport and transfer device 600 includes a third linear drive 610 located at the unloading position of the unloading transport device 500. The moving end of the third linear drive 610 is fixedly mounted with a mounting plate 620, and at least one fourth gripper cylinder 630 is fixedly mounted on the mounting plate 620.

[0072] See Figure 12 As shown, in this embodiment, there are two fourth gripper cylinders 630. After the roller is placed into the clamping and fixing assembly 920, the fourth gripper cylinder 630 clamps the axle and drives the axle to move to the next station. It can be understood that since the axle passes through the first bearing, the spacer ring and the second bearing, the roller moves at the same time as the third linear drive 610 drives the axle clamped by the fourth gripper cylinder 630. Specifically, the axle is moved to the position of the screwing device 800 to lock the bolt.

[0073] The screwing device 800 includes a fourth two-axis transfer module 810. An electric screwdriver 820 is fixedly installed on the moving end of the fourth two-axis transfer module 810. A torque tester 830 and a bolt feeder 840 for providing bolts to the electric screwdriver 820 are provided on the moving path of the fourth two-axis transfer module 810.

[0074] Please see Figure 15As shown, in order to fix the axle, bolts are screwed into the threaded holes of the axle, thereby fixing the axle to the second bearing. Specifically, when it is necessary to tighten the bolts, the electric screwdriver 820 is first moved to the position of the torque tester 830 through the fourth two-axis transfer module 810. The torque tester 830 measures the torque of the electric screwdriver 820 to prevent the output torque of the electric screwdriver 820 from being too high and damaging the bolts, and to prevent the output torque of the electric screwdriver 820 from being too low and unable to tighten. Furthermore, the bolt feeder 840 provides bolts to the electric screwdriver 820.

[0075] It should be noted that the torque tester 830 and the bolt feeder 840 are existing components, and their working principles will not be elaborated here.

[0076] A clamping and unloading conveying device 900 is provided on one side of the fourth feeding device 700. The clamping and unloading conveying device 900 includes a mounting base 910, on which at least one clamping and fixing component 920 is fixedly mounted. The clamping and fixing component 920 is the clamping position of the clamping and unloading conveying device 900. The clamping and fixing component 921 includes a fifth gripper cylinder 921, on which clamping blocks 922 for clamping the wheel shaft are fixedly mounted. The clamping block 922 is also provided with a limiting groove 923. A fourth linear drive member 924 is fixedly installed on one side of the fifth gripper cylinder 921. A moving plate 925 is fixedly installed on the moving end of the fourth linear drive member 924. The moving plate 925 is slidably installed on the mounting base 910. A driven fork 926 is provided on the moving plate 925. The fourth linear drive member 924 drives the moving plate 925 to move so that the driven fork 926 extends into the limiting groove 923.

[0077] See Figure 16 and Figure 17 As shown, there are three workstations on the mounting base 910. The first and second workstations are both equipped with clamping and fixing components 920, that is, there are two clamping and fixing components 920. One of them is located at the unloading position of the fourth feeding device 700, which is the first workstation. The other clamping and fixing component 920 is located at the screwing position of the screwing device 800. Specifically, when the bolt is screwed, the wheel axle needs to be stable. Since the wheel axle passes through the first bearing, the spacer ring and the second bearing, plus the weight of the rolling track, it is easy to cause positional displacement. Therefore, the clamping and fixing component 920 is needed to clamp and fix the wheel axle.

[0078] Please continue reading. Figure 17As shown, the axle from the fourth feeding device 700 is first clamped and fixed by the clamping and fixing assembly 920 at the first station. Then, a roller with a first bearing, a spacer ring, and a second bearing is installed. Next, the fourth gripper cylinder 630 clamps and transports the axle from the first station to the clamping and fixing assembly 920 at the second station. The bolt is screwed onto the axle by the screwing device 800, thereby fixing the axle and forming a complete wheel. Then, the axle is clamped by the mounting plate 620. After clamping, the wheel is transported to the third station for inspection with the cooperation of the third linear drive 610.

[0079] In this embodiment, in order to prevent the axle from shifting, the fifth gripper cylinder 921 first drives the two limiting grooves 923 to move closer to each other to clamp the axle located between them. After clamping, the fourth linear drive member 924 drives the moving plate 925 to move, thereby extending the driven fork 926 into the limiting groove 923. The driven fork 926 fixes the position of the clamping block 922, thereby preventing the clamping block 922 from moving and causing the axle to shift.

[0080] In this embodiment, both the fifth gripper cylinder 921 and the fourth linear drive component 924 are cylinders.

[0081] The conveyor line includes a first conveyor line 930 located on one side of the mounting base 910, a second conveyor line 940 is provided at the end of the first conveyor line 930, and a fifth linear drive member 950 is provided at the feed end of the second conveyor line 940.

[0082] See Figure 16 As shown, the third station of the mounting base 910 is located at the loading position of the first conveyor line 930 and the second conveyor line 940. The assembled wheel is transported to the third station by the cooperation of the third linear drive 610 and the mounting plate 620. At this position, the entire wheel assembly can be inspected manually to see if it is qualified, or a visual inspection device can be used to check if it is qualified. There is no limitation here. If the wheel fails the inspection, the fifth linear drive 950 pushes the unqualified wheel to the first conveyor line 930. If the wheel is qualified, it is transported downstream through the second conveyor line 940.

[0083] It is understandable that the first conveyor line 930 and the second conveyor line 940 have the same structure. Specifically, the first conveyor line 930 can be composed of two roller conveyor lines with a certain gap between them to avoid the wheel axle and prevent motion interference.

[0084] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
