[0056] In other embodiments, the hot-melting device 42 and the gripping device 44 can also move independently of each other.

[0057] Please see Figure 1 , Figure 7 and Figure 8The wheel mounting unit 5 includes a second assembly fixture 52 for fixing the vehicle base, a wheel feeding mechanism 54 for providing the wheel 50, and two pressure roller mechanisms 56 correspondingly arranged on both sides of the second assembly fixture 52. The pressure roller mechanisms 56 are used to install the wheel 50, and the wheel feeding mechanism 54 provides the wheel 50 to the two pressure roller mechanisms 56. After the gripping device 44 of the fixing and gripping unit 4 grips the vehicle base after the wheel axle fixing is completed, it is transferred to the second assembly fixture 52 for fixing. The end of the pressure roller mechanism 56 near the second assembly fixture 52 is provided with a positioning groove (not shown) for accommodating the wheel 50. The positioning groove (not shown) is adapted to the wheel 50. The pressure roller mechanism 56 includes a push rod device for pressing the wheel 50 into both ends of the wheel axle 30. The wheel feeding mechanism 54 transports the wheel to the positioning groove of the pressure roller mechanism 56, and the push rod device presses the wheel 50 in the positioning groove into both sides of the wheel axle 30 on the vehicle base on the second assembly fixture 52. The wheel feeding mechanism 54 includes a wheel screening device 542 and a wheel guide rail 544 that guides the positioning groove; the wheel guide rail 544 is adapted to the wheel 50.

[0058] In this embodiment, the wheel mounting unit 5 further includes a third frame 51, and the wheel sorting device 542 is disposed on the third frame 51, located on one side of the assembly platform 22. The wheel sorting device 542 includes a wheel material trough 5422 for accommodating the wheel 50, a wheel spiral conveyor (not shown) disposed inside the wheel material trough 5422, and a fourth vibrator (not shown) connected to the wheel spiral conveyor. The end of the wheel spiral conveyor is connected to the beginning of the wheel guide rail 544. The end of the wheel guide rail 544 guides the positioning groove 562. The pressure roller mechanism 56 is fixed on the main frame 21, and the second assembly fixture 52 can move relative to the pressure roller mechanism 56. Specifically, the second assembly fixture 52 is controlled by a servo motor and moves perpendicular to the pressure roller direction of the pressure roller mechanism 56. Under the vibration of the fourth vibrator, the wheels 50 in the wheel feeder 5422 automatically and orderly move upward along the wheel spiral conveyor to the end of the wheel spiral conveyor and enter the wheel guide rail 544. Then, they enter the positioning groove one by one along the wheel guide rail 544. The second assembly fixture 52 moves relative to the pressure roller mechanism 56 so that the two ends of the front wheel axle on the base of the second assembly fixture 52 are aligned with the center of the wheel 50 in the positioning groove. The push rod device presses the wheel 50 in the positioning groove into both sides of the front wheel axle on the base of the second assembly fixture 52 and then resets, and the new wheel 50 enters the positioning groove. Subsequently, the second assembly fixture 52 moves relative to the pressure roller mechanism 56 so that the two ends of the rear wheel axle on the base of the second assembly fixture 52 are aligned with the center of the wheel 50 in the positioning groove. Similarly, the push rod device presses the wheel 50 in the positioning groove into both sides of the rear wheel axle on the base of the second assembly fixture 52 and then resets, and the new wheel 50 enters the positioning groove, thereby completing the installation of the wheel 50. Specifically, the push rod device includes a push rod and a cylinder for controlling the movement of the push rod. The installation sequence of the front and rear axles of the wheels 50 on the chassis (i.e., the direction of movement of the second assembly fixture 52) can be changed according to actual production requirements.

[0059] In other embodiments, the end of the pressure wheel mechanism 56 near the second assembly fixture 52 may be provided with two positioning grooves, the distance between the centers of the wheels 50 in the two positioning grooves being the same as the distance between the front and rear axles of the vehicle base; the pressure wheel mechanism 56 includes two push rod devices corresponding to the positioning grooves, the push rod devices pressing the wheels 50 in the corresponding positioning grooves into both sides of the axles 30 on the vehicle base on the second assembly fixture 52. In other embodiments, the end of the pressure wheel mechanism 56 near the second assembly fixture 52 may be provided with two positioning grooves 562, the distance between the centers of the wheels 50 in the two positioning grooves being the same as the distance between the front and rear axles of the vehicle base; the push rod device of the pressure wheel mechanism 56 has two ends corresponding to the positioning grooves, the push rod devices simultaneously pressing the wheels 50 in the positioning grooves into both sides of the front and rear axles on the vehicle base on the second assembly fixture 52.

[0060] As a further improvement to the above solution, the wheel mounting unit 5 further includes a fixing device 58 disposed above the second assembly fixture 52; the fixing device includes a fixing top rod that presses the base against the second assembly fixture 52 and a cylinder that controls the fixing top rod. In this embodiment, the fixing device 58 is disposed between the wheel guide rails 544 that guide the positioning grooves on both sides of the second assembly fixture 52, and is fixedly connected to the two wheel guide rails 544. When the second assembly fixture 52 moves between the pressure wheel mechanism 56 so that the two ends of the wheel axle 30 on the base of the second assembly fixture 52 are aligned with the center of the wheel 50 on the positioning groove, the cylinder of the fixing device pushes the fixing top rod to press against the surface of the base of the second assembly fixture 52, so that the base of the second assembly fixture 52 cannot move; after the top rod device of the pressure wheel mechanism 56 presses the wheel 50 in the positioning groove into both sides of the wheel axle 30 on the base of the second assembly fixture 52, the cylinder of the fixing device controls the fixing top rod to move upward away from the surface of the base of the second assembly fixture 52. The fixing device 58 can prevent the wheel 50 from being misaligned on the base of the second assembly fixture 52 during the process of the push rod device of the pressure wheel mechanism 56 pressing the wheel 50 into both sides of the axle 30, which would prevent the wheel 50 from being installed smoothly.

[0061] As a further improvement to the above solution, the distance between the first assembly fixture 22 corresponding to the fixing and gripping unit 4 and the wheel mounting unit 5 and the second assembly fixture 52 is the same as the distance between the hot melt device 42 and the gripping device 44. Furthermore, the line connecting the first assembly fixture 22 and the second assembly fixture 52 is parallel to the moving direction of the slider 43. This allows the gripping device 44 of the fixing and gripping unit 4 to move above the second assembly fixture 52 of the wheel mounting unit 5, while the hot melt device 42 moves above the first assembly fixture 24. This allows the gripping device 44 to transfer the fixed car base while the hot melt device 42 completes the wheel axle fixing of the next first assembly fixture 22 onto the car base. Thus, the fixing and gripping unit 4 can simultaneously fix and transfer the wheel axles of two model car bases, reducing processes and improving processing efficiency.

[0062] As a further improvement to the above solution, the wheel feeding mechanism 54 further includes a fifth vibrator (not shown) fixedly connected to the wheel guide rail 544 and a second detection mechanism (not shown) disposed at the middle position and / or end of the wheel guide rail 544. The vibration of the fifth vibrator moves the wheel 50 on the wheel guide rail 544 to the end of the wheel guide rail 544. The second detection mechanism detects whether there is material at the middle position and / or end of the wheel guide rail 544 through a sensor and sends material presence / absence information to the second control device 26; when no material is detected at the middle position and / or end of the wheel guide rail 544, the second control device 26 controls the fourth vibrator and the fifth vibrator 546 to start vibrating; when material is detected at the end of the wheel guide rail 544, the second control device 26 controls the fourth vibrator and the fifth vibrator 546 to stop vibrating.

[0063] As a further improvement to the above solution, the wheel spiral conveyor is provided with special obstacles (not shown) to correct the orientation and direction of travel of the wheel 50. Specifically, the special obstacles and the wheel spiral conveyor form a transmission channel and a non-transmission channel that conform to the shape of the wheel 50. In addition, the special obstacles can flip the orientation of the wheel 50 and change the direction of travel of the wheel 50 by colliding with the axle 30, so that the wheel 50 enters the transmission channel in the correct orientation; while the wheel 50 that is not in the correct orientation re-enters the wheel trough 5422 from the non-transmission channel.

[0064] The automatic assembly equipment for model car wheel components of this utility model also includes a discharge device 6 for gripping and transferring the car base on the second assembly fixture 52.

[0065] In this embodiment, the discharge device 6 is disposed beside the second assembly fixture 52 and fixed to the main frame 21. After the wheel 50 is assembled, the second assembly fixture 52 moves out of the space between the pressure wheel mechanisms 56, and the discharge device 6 moves above the second assembly fixture 52, grabs the assembled vehicle base on the second assembly fixture 52, and slides it through a slide rail disposed on the edge of the main frame 21 into the loading box placed beside the main frame 21.

[0066] The working process of the automatic assembly equipment for model car wheel components of this utility model is as follows:

[0067] The raw material for the car base slides from the outlet of the car base hopper 124 to the conveying device 122 and is conveyed to the tray 144. The first vibrator 142 vibrates for 2 to 3 seconds, causing the car bases on the tray 144 to flip, rotate, move and be evenly distributed in the tray 144. After the first vibrator 142 stops vibrating, the first control device 19 identifies the placement status of the car base in the image captured by the visual input lens 162 and marks the car bases that meet the installation status. It then controls the car base gripping device 18 to grab the marked car bases and place and fix them on the first assembly fixture 24 located at the car base assembly position on the assembly platform 22. The divider drives the assembly platform 22 to rotate, causing the first assembly fixture 24, which holds the vehicle base, to rotate to the front axle assembly position. The axle fixture of the front axle mounting unit grasps the axle and moves it to the first assembly fixture 24 at the front axle assembly position, aligning the through hole 301 of the axle with the assembly shaft at the front of the vehicle base. The pressing device then mounts the axle onto the vehicle base by passing it through the assembly post 101 at the front of the vehicle base on the first assembly fixture 24. Similarly, the divider drives the assembly platform 22 to rotate, causing the first assembly fixture 24, which holds the vehicle base with the front axle installed, to rotate to the rear axle assembly position. The axle fixture of the rear axle mounting unit grasps the axle and moves it to the first assembly fixture 24 with the vehicle base with the front axle installed, aligning the through hole 301 of the axle 30 with the assembly shaft at the rear of the vehicle base. The pressing device then mounts the axle onto the vehicle base by passing it through the assembly post 101 at the rear of the vehicle base. The divider drives the assembly platform 22 to rotate, causing the first assembly fixture 24, which holds the vehicle base with the front and rear axle installation completed, to rotate to the wheel assembly position. The slider 43 moves along the transverse axis of the T-shaped frame 41 to the assembly platform 22, causing the hot melt device 42 to move first to the top of the first assembly fixture 24 with the vehicle base with the axle installation completed. The hot melt device 42 melts the assembly post 101 on the vehicle base to form a limiting part 1011 that restricts the movement of the axle, thereby achieving the fixation of the axle. After fixation, the slider 43 continues to move along the transverse axis of the T-shaped frame 41 to the assembly platform 22, causing the gripping device 44 to move above the first assembly fixture 24. The gripping device 44 grips the vehicle base with the axle fixed from the first assembly fixture 24 and transfers it to the second assembly fixture 52 of the wheel mounting unit 5. The second assembly fixture 52 is moved relative to the pressure roller mechanism 56 under the control of the servo motor, so that the two ends of the front wheel axle on the car base on the second assembly fixture 52 are respectively aligned with the center of the wheel 50 on the positioning groove 562 of the two pressure roller mechanisms 56. The cylinder of the fixing device 58 pushes the fixing rod to press against the surface of the car base on the second assembly fixture 52. The rod device presses the wheel 50 in the positioning groove of the pressure roller mechanism 56 into both sides of the front wheel axle on the car base on the second assembly fixture 52 and then resets, and the new wheel 50 enters the positioning groove. The cylinder of the fixing device 58 controls the fixing rod to leave the surface of the car base on the second assembly fixture 52.The second assembly fixture 52 continues to move relative to the pressure roller mechanism 56 under the control of the servo motor, aligning the two ends of the rear wheel axle on the base of the car on the second assembly fixture 52 with the center of the wheel 50 on the positioning groove. The cylinder of the fixing device 58 pushes the fixing rod to press against the surface of the car base on the second assembly fixture 52 again. The push rod device 564 presses the wheel 50 in the positioning groove 562 into both sides of the rear wheel axle on the car base of the second assembly fixture 52 and then resets, completing the wheel assembly of the car base on the second assembly fixture 52. The cylinder of the fixing device 58 controls the fixing rod to leave the surface of the car base on the second assembly fixture 52. Subsequently, the second assembly fixture 52 continues to move out from between the two pressure roller mechanisms 56 under the control of the servo motor and moves to the side of the discharge device 6. The discharge device 6 moves above the second assembly fixture 52, grabs the assembled car base on the second assembly fixture 52 and slides the car base into the loading box next to the main frame 21 through the slide rail. Thus, the automatic assembly of the model wheel axle and wheel components is completed. Operators only need to debug the equipment before assembly, add raw materials to the base hopper 124, axle trough 322, and wheel trough 5422, and start the automatic assembly equipment for model car wheel components described in this utility model to realize the automatic assembly of model car wheel axles and wheel components, which improves processing and production efficiency and reduces labor costs.

[0068] In addition, while the gripping device 44 transfers and fixes the wheel axle-mounted car base to the second assembly fixture 52, the divider drives the assembly platform 22 to rotate, causing the first assembly fixture 24, which is equipped with the next wheel axle-mounted car base, to rotate to the corresponding assembly position of the gripping unit 4. When the gripping device 44 moves above the second assembly fixture 52, the hot melt device 42 moves above the first assembly fixture 24, which is equipped with the next wheel axle-mounted car base, to fix the wheel axle on the next car base in the same way, saving processes and further improving production efficiency.

[0069] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
