Description

Technical Field

[0001] The present invention relates to the technical field of alloy plastic car models, and particularly relates to an automatic wheel - inserting device for a giant wheel toy car. Background Art

[0002] An alloy plastic car model is a simulation - scale model that is completely in accordance with the shape and color of a real car and is disassembled into a varying number of components according to the real - car structure, and is assembled in strict proportion. The whole model is composed of different components, such as components of structures like the body, doors, car bottom, wheels, etc. After mold - making, processing, and decorative coloring, employees use tooling tools / equipment to assemble each component into a highly - simulated car model product with collection value.

[0003] Since the design and development of car models are based on real cars for structural design, like real cars, each component needs to be assembled together through worker production. Workers repeating the same work for a long time is not only boring but also greatly increases the workers' work intensity and makes them prone to fatigue. For example, in the design of wheel models, they are generally designed as two main components, namely the tire and the wheel hub. During the assembly process, such as in the assembly of engineering - vehicle models and farmer - vehicle models, workers need to manually use tools to fit them together and assemble them individually by hand.

[0032] The present invention will be further described in detail below in conjunction with the specification drawings and specific embodiments.

[0033] As Figure 1 、 Figure 2 shown, an automatic wheel-inserting device for a giant wheel toy car includes a tire feeding device 1 and a wheel core feeding device 2. Among them, the tire feeding device 1 and the wheel core feeding device 2 are respectively connected with a first screening device 3 and a second screening device 4. The structures of the first screening device 3 and the second screening device 4 are the same, and they are composed of a funnel iron trough 16, a screening track 17, a vibration mechanism A, a feeding trough 18, a limiting device, and a vibration mechanism B. The specific structure and working principle have been disclosed in the Chinese patent with the application number 202021365729.6. According to the vibration principle generated by the vibration mechanism A, the funnel iron trough vibrates at a certain vibration frequency to screen products from the funnel iron trough along the unique spiral channel of the screening track to select products in the correct orientation. When the product passes through the screening track and gradually rises in the spiral design, the screening track is provided with special obstacles at a certain position, so as to identify the products in the required correct orientation, enable the products meeting the orientation requirements to pass through the special obstacles in the screening track and be sent into the feeding trough, while the products with incorrect orientations fall into the funnel iron trough to repeat the work process. The product (tire or wheel core) enters the feeding trough after passing through the screening track. In the feeding trough, the vibration source generated by the vibration mechanism B pushes the product towards the end of the feeding trough 18; an inductor is arranged at an appropriate position in the feeding trough to sense the quantity of products in the feeding trough and confirm whether the screening device needs to work; the inductor at the end of the feeding trough is used to sense whether there is a product, and feedback the information to the feeding device A or the feeding device B. At the same time, to ensure that the feeding device A5 or the feeding device B6 can grab the product in the feeding trough 18, at the same time, a limiting mechanism is arranged at the end of the feeding trough 18 to limit that only one product is suitable for the feeding device A5 or the feeding device B6 to grab each time.

[0034] Above the ends of the feeding troughs 18 of the first screening device 3 and the second screening device 4, a feeding device A5 and a feeding device B6 are respectively arranged. The feeding device B6 grabs the wheel cores and places the wheel cores screened by the second screening device 4 into the tires screened by the first screening device 3, so that the wheel cores are preliminarily stacked on the tires. Then, the feeding device A5 grabs the tires with the wheel cores placed thereon and places the tire-wheel core assembly onto the conveying device 7. That is, the feeding device B6 grabs the wheel cores from the end of the feeding trough 18 in the second screening device 4 and places them on the tires at the end of the feeding trough 18 in the first screening device 3. When the feeding device B6 is working, the feeding device A5 grabs the wheel core-tire assembly that has been stacked well from the end of the feeding trough 18 in the first screening device 3 and places it onto the conveying device 7, synchronously completing the actions of one grab and one release.

Moreover, the first slide rail 20 and the second slide rail 23 partially overlap at the end feeding trough 18 of the first screening device 3. When the first electric fixture 19 grabs the wheel core-tire assembly, during the process of moving downward under the drive of the first air cylinder 18, it can also apply a certain pressure to the wheel core, so that the wheel core is effectively sleeved into the tire.

[0036] Continue to refer to Figure 4 , in the present invention, the conveying device includes a conveying conveyor belt 24 for receiving and conveying the wheel core-tire assembly grabbed and sent by the feeding device A5.

The first in-position confirmation device 8 is located in the downstream direction of the second electric fixture 22, and the feeding device C26 is located in the downstream direction of the first in-position confirmation device 8. The conveying conveyor belt 24 is also provided with a quantity sensor for sensing the quantity of the wheel core-tire assembly. After the feeding device A5 grabs and places the stacked wheel core-tire assembly onto the receiving end of the conveying device 7, the wheel core-tire assembly is conveyed along with the conveying conveyor belt 24 towards the end direction of the conveying device, and the quantity sensor senses the quantity of the products on the conveying device to confirm whether the feeding device A5 needs to grab and send the wheel core-tire assembly onto the conveying device 7. During the process of the wheel core-tire assembly from the feeding end to the end of the conveying device 7, the first in-position confirmation device 8 on the conveying device can correct the wheel core-tire assembly that has deviated during the grabbing process of the feeding device A5. A quantity sensor is arranged at the end of the conveying device 7, and a feeding device C26 is arranged above the end.

[0041] In addition, a second positioning confirmation device 28 is fixedly installed on the wheel entry frame 12. The second positioning confirmation device 28 has the same structure as the first positioning confirmation device 8, and the second positioning confirmation device 35 corrects the posture of the tire wheel core assembly grabbed by the loading device C26 and placed into the wheel clamp 11.

[0048] In addition, the following devices are also provided in the present invention:

[0049] 1. Function control screen 44: It is placed at one end of the frame close to the staff. The operation and use of the equipment are realized through the function control screen.

[0050] 2. Safety protection device 45: It is placed on one side of the frame close to the staff to prevent the operator's hand or other limbs from accidentally entering the feeding device C and the wheel entering frame during the mechanical operation, resulting in mechanical injury. In the full-automatic mode of the equipment, when the operator's hand or other limbs enter this area, the equipment will stop.

[0052] 4. Circuit control system 47: It is connected to all mechanisms and devices to meet the realization of the required functions.

[0053] The working principle of the present invention is as follows:

[0054] 1. The feeding device quantitatively conveys the products (wheel core, tire) to the hopper iron trough in the screening device according to the conveying amount set by the hopper iron trough through the quantity sensor. After meeting the requirement, the feeding device stops feeding.

[0055] 2. The screening device screens the products from the hopper iron trough according to the material shortage signal given by the feeding trough along the screening track at a certain vibration frequency set by the vibration mechanism A and sends them into the feeding trough. Then, the vibration mechanism B vibrates the feeding trough at a certain frequency to send the products to the end of the feeding trough. Until the capacity of the feeding trough is reached and the full material sensor is touched, the hopper iron trough, the screening track, and the vibration mechanism A stop feeding.

[0056] 3. After the product is sent to the end of the feeding chute by the vibration mechanism B, it touches the sensor, which transmits a signal to the feeding device A or the feeding device B. The feeding device B grabs the wheel core from the end of the feeding chute in the second screening device and places it on top of the tire at the end of the feeding chute in the first screening device. When the feeding device B is working, the feeding device A grabs the stacked wheel core and tire assembly from the end of the feeding chute in the first screening device and places it on the conveying device.

[0057] 4. After the wheel core and tire assembly is grabbed by the feeding device A and placed on the conveying device, it is conveyed towards the end of the conveying device by the conveying conveyor belt. The sensor confirms the number of wheel core and tire assemblies at the end of the conveying device to meet the requirements for the feeding device C to grab. The sensor on the conveying device confirms the number of products on the conveying device and feeds back a signal to the feeding device A or the feeding device B to confirm whether it is still necessary to grab and send wheel core and tire assemblies to the conveying device. During the process of the wheel core and tire assembly being conveyed on the conveying conveyor belt to the end of the conveying device, after the position is confirmed correctly by the first positioning confirmation device, it is confirmed that the wheel core has been sleeved into the tire.

[0058] 5. The feeding device C receives the signal transmitted by the sensor, drives the feeding device C to grab the wheel core and tire assembly from the end of the conveying device, and places it in the wheel fixture in the assembly platform.

[0059] 6. After the assembly platform receives the signal indicating that the feeding by the feeding device C is completed, it rotates the assembly platform and the wheel fixture already loaded with the wheel core and tire assembly to be directly below the second positioning confirmation device. After the second positioning confirmation device receives the signal indicating that the rotation of the assembly platform is completed, it pats the product to confirm that the wheel core has been sleeved into the tire and to confirm that the tire is in an effective posture in the wheel fixture.

[0060] 7. After the assembly platform receives the signal indicating that the patting by the second positioning confirmation device is completed, it rotates the assembly platform and the wheel fixture that has patted the product to be directly below the wheel insertion assembly device. After the wheel insertion assembly device receives the signal indicating that the rotation of the assembly platform is completed, the positioning device, clamping device, prying-in device, and wheel insertion rotation device in the wheel insertion assembly device synchronously complete five actions of positioning, clamping, inserting the rod, fixing, and rotating according to the program flow, realizing the insertion of the wheel core into the tire and completing the assembly of the wheel.

[0061] 8. After the assembly platform receives the signal indicating that the wheel insertion is completed transmitted by the wheel insertion assembly device, it rotates the assembly platform (driven by the other motor to rotate) and the wheel fixture with the product that has completed the wheel insertion to be directly below the discharging device. After the discharging device receives the signal indicating that the rotation of the assembly platform is completed, it grabs the wheel and places it in the discharging chute, and the product falls into the collection basin along the discharging chute.

[0062] 9. Multiple wheel fixtures are placed on the assembly platform, which can continuously receive products from the feeding device C in a cycle. The assembly platform, the feeding device C, the wheel assembly device, and the discharging device form a continuous cyclic production process. The products are fed from the feeding device, screened by the screening device, the preliminary wheel insertion of the wheel core and the tire is completed by the feeding device, and the final wheel insertion is completed on the assembly platform.

[0063] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
