Description

Technical Field

[0001] The invention relates to the technical field of wheel rim processing, in particular to an automatic installation device for wheel rim accessories. Background Art

[0002] With the development of the automobile industry, the demand for vehicles is increasing, and the performance requirements for vehicles are getting higher and higher, especially in terms of quietness and comfort. At present, the common solution for driving system quietness is to avoid the generation and transmission of resonance in the vehicle, add quiet cotton to absorb sound and reduce noise. The most significant of this technology is tire quiet cotton, that is, a layer of quiet cotton is pasted on the inside of the tire for noise reduction. With the development of industry, this technology has gradually been monopolized by tire companies. In order to alleviate the profit loss caused by this technology to the OEM, the technology of pasting quiet cotton on the rim has been introduced. The effect is the same as pasting it on the tire, and it has a significant effect on the cavity sound of the vehicle in the frequency band of 180-250Hz.

[0003] The pasting of silent cotton on the rim is different from that on the tire. The inside of the tire is relatively flat and can be pasted by equipment or manually, but the pasting of silent cotton on the rim needs to take into account the trend of the rim part required by regulations. If it is pasted purely by hand, the efficiency and effect will be reduced, and the silent cotton may not be firmly pasted to the rim after pasting, resulting in the problem of falling off later. The existing manual auxiliary equipment is slow to install and requires special personnel to carry, wipe, clean, assemble, etc. In addition, the manual auxiliary tool assembly does not have a pre-heating step for the rim, which may cause the adhesion of the paste after assembly to be unreliable.

[0004] Currently, there is no automatic pasting tool or device for pasting the silent cotton on the rim. In addition, the common way of producing the valve stem line body is to install it manually, and then assemble the line body tire and the tire, but this installation method is relatively inefficient. Summary of the invention

[0005] In view of the shortcomings of the prior art mentioned above, the purpose of the present invention is to provide an automatic rim accessories installation device to solve the problem that there is no device in the prior art for automatically sticking silent cotton on the rim and installing the valve stem at the same time, as well as to solve the problem of automatically cleaning and pre-heating the rim when assembly is required.

[0030] For example, see Figure 1 and Figure 2The present invention provides an automatic installation device for rim accessories, including a silent cotton storage table 802, an installation unit 3 and a conveying mechanism 1. The silent cotton storage table 802 is used to store the silent cotton 8; the installation unit 3 includes a first workbench 13, a high-definition camera 6 and a silent cotton installation component. The high-definition camera 6 is set at any position on the top of the first workbench 13. The photo data obtained from the high-definition camera 6 is used to determine and calculate the rotation angle of the silent cotton installation component. The silent cotton installation component rotates the rim to the corresponding angle according to the calculation result to paste the silent cotton 8; the conveying mechanism is used to transport the rim 5 to the installation unit 3 for the installation of the silent cotton 8; the silent cotton storage table 802 and the conveying mechanism 1 are respectively located on different sides of the installation unit 3. The controller for controlling the operation of the above-mentioned automatic installation device is not shown.

[0031] Specifically, the conveying mechanism 1 includes a conveying roller (which may also be a conveyor belt), and the conveying roller is driven by a cylinder (not shown) to convey the rim. The silent cotton installation assembly includes a rolling device 11, a first cylinder 9 and a second cylinder 10. Two second rollers 112 positioned with a contoured belt are arranged at the end of the silent cotton rolling device 11, and the second roller 112 is a plastic roller (for example, an extrusion wheel). Because the rim 5 has a certain curve in its movement, the wheel head of the second roller 112 has a certain elasticity and can change its shape with the movement of the rim 5. A first cylinder 9 is arranged at the top of the first workbench 13, and a second cylinder 10 is arranged at the bottom, wherein the first cylinder 9 is located above the first conveyor belt workbench 131, and the second cylinder 10 is located below the first conveyor belt workbench 131. The first conveyor belt workbench 131 is connected to the first workbench 13 using screws or welding technology. The first conveyor belt workbench 131 drives the conveyor belt 121 through the motor 12 to provide power for the transmission of the conveyor belt 121 and transport the rim 5, thereby facilitating the assembly between the rim 5 and the silent cotton 8.

[0032] The conveying mechanism 1 transfers the rim 5 to the first conveyor belt workbench 131. The second cylinder 10 is provided with a sleeve that cooperates with the center hole of the rim 5 to lift the rim 5. The high-definition camera 6 is used to take pictures and calculate the conveying position of the rim 5 and the lifting position of the second cylinder 10. The photographed photo signal is transmitted to the controller (not shown). The controller calculates and judges, and directs the motor (not shown) to drive the second cylinder 10 to move to the center hole position of the rim 5. The second cylinder 10 lifts the rim 5, and then the first cylinder 9 above the first conveyor belt workbench 131 presses it tightly, takes pictures through the high-definition camera 6, and determines and compares it through the control system to confirm the current installation position of the silent cotton on the rim 5. The control system starts the silent cotton installation program. There is a release paper on the back of the silent cotton 8. There is a rolling slide rail at the first roller 801, which can be controlled by the cylinder (not shown) to peel off the release paper. During the process of the first roller 801 rotating and conveying forward, the silent cotton 8 after peeling off the release paper is glued to the rim 5 and starts to stick. The second cylinder 10 drives the rim 5 to rotate and paste the silent cotton 8. After the pasting is completed, the rolling device 11 advances to the rolling position through the slide rail 111 according to the pre-set program. The second cylinder 10 drives the rim 5 to rotate, and the second roller 112 at the end of the rolling device 11 rotates to roll the silent cotton 8. After the silent cotton 8 is pasted, the first cylinder 9 and the second cylinder 10 release the rim 5, and the rim 5 is transferred to the next step through the conveying mechanism 1 to assemble the tire rim.

[0033] For example 2, please refer to Figure 1 and Figure 3 , a valve installation assembly is added on the basis of the first embodiment. The valve installation assembly includes a valve installation robot arm 7, a second slide 701 and a cylinder (not shown in the figure). The second slide 701 is used to install the valve (not shown in the figure). The second slide 701 is installed on the first conveyor workbench 131, and the valve installation robot arm 7 is slidably arranged on the second slide 701. The high-definition camera 6 captures the rim 5 and determines the wheel type, and sets the moving position according to the wheel type. The second slide 701 can be set in advance according to the size of the rim, and can be adjusted to move away from the rim or close to the rim, and automatically slide to the corresponding position.

[0034] During operation, a picture is taken through the high-definition camera 6 on the top of the first workbench 13, and the control system is used to determine and compare to confirm the current position of the valve nozzle, and the valve nozzle position is rotated by a certain angle to reach the valve nozzle installation position on the rim 5. At this time, the valve nozzle installation robot arm 7 installs the pre-grabbed valve nozzle, and then the rim is rotated 180° through the cylinder to turn the valve nozzle position to the silent cotton 8 installation position. The control system starts the silent cotton installation program, removes the release paper on the back of the silent cotton 8, and starts pasting at a preset distance from the valve nozzle.

[0035] For example 3, please refer to Figures 1 to 4 , a temperature maintenance unit 4 is added on the basis of the first embodiment. The temperature maintenance unit 4 includes a second workbench 14 and a temperature lamp 401. The temperature lamp 401 is arranged on the top of the second workbench 14 to keep the temperature maintenance unit 4 at a constant temperature. The second workbench 14 is provided with a second conveyor belt workbench 141. After the rim 5 is preheated in the temperature maintenance unit 4, it is transferred to the installation unit 3 through the second conveyor belt workbench 141. Specifically, the silent cotton 8 is placed on the silent cotton storage table 802. The conveying mechanism 1 includes a first conveying slide rail 101 and a second conveying slide rail 102. The rim 5 is transferred into the first workbench 13 through the slide rail 101. The first workbench 13 is provided with a first conveyor belt workbench 131. The temperature lamp 401 is installed on the top of the first workbench to provide a constant temperature and ensure that the operating space of the first workbench 13 is kept at a certain temperature. For example, the temperature is set at 50°C and the heating time is 2 minutes to preheat the rim 5. The temperature lamp 401 can adjust the temperature of the rim 5 to any temperature suitable for pasting the silent cotton 8 before pasting according to requirements to ensure the pasting effect. The preheated rim 5 is conveyed to the first workbench 13 through the conveying mechanism 1 for pasting and installation of the silent cotton 8. It should be noted that the temperature lamp 401 can be set according to the production line conditions and the ambient temperature, and the power size and preheating time can be adjusted.

[0036] Example 4, please refer to Figure 4 and Figure 5 , a cleaning unit 2 is added on the basis of the third embodiment, and the cleaning unit 2 is arranged before the temperature maintaining unit 4. The rim 5 is conveyed from the product online point 15 into the cleaning unit 2 through the conveying mechanism 1. The cleaning equipment is arranged on the working platform to clean and wipe the rim 5. The cleaning unit 2 includes a first slide 201, a cleaning roller 202 and a sponge 203. The sponge 203 is installed on two cleaning rollers 202. The first slide 201 is driven by a cylinder (not shown) to slide to the position of the rim 5, and the cleaning roller 202 drives the sponge 203 to clean the rim 5. After cleaning, the rim 5 is transferred to the temperature maintaining unit 4 through the conveying mechanism 1. When temperature maintenance is not required, the temperature maintaining unit 4 can be removed and directly transferred to the installation unit 3. The rim 5 flows out from the product offline point 16 after the installation of the silent cotton and the valve nozzle.

[0037] For example 5, please refer to Figures 1 to 3 The temperature maintaining unit 4 and the cleaning unit 2 in the fourth embodiment may also be arranged in the same workbench, and the temperature lamp 401 may be turned on after the rim 5 is cleaned.

[0038] Example 6, please refer to Figures 1 to 5 The rim 5 in any one of the above embodiments 1 to 5 can be delivered by grabbing and delivering it by a robot arm gripper.

[0039] As can be seen from the above, the applicability of the present invention is very high. Before the rim 5 is pasted with the silent cotton 8, it can be decided whether to set the temperature maintenance unit 4 to preheat the rim 5 according to the actual needs such as the ambient temperature at that time. The temperature lamp 401 can be added to any upper position in the temperature maintenance unit 4 to ensure that the adhesion between the silent cotton 8 and the rim 5 can be better exerted during assembly. Each part can be adjusted in steps according to the actual production situation and the position of each component or unit can be adjusted. Each workbench can be a closed dust-proof space or a semi-enclosed space. The silent cotton 8 is pasted by driving two rollers driven by a motor to pull up the silent cotton 8 and drive it forward, separating the release paper while moving, saving the time of removing the release paper during production. The rollers then deliver the silent cotton 8 without the release paper to the rim 5. The rolling device 11 can rotate the rim 5 according to the photo comparison to ensure the starting position of the silent cotton 8. It can not only start pasting from the set position, but also press the silent cotton 8 while pasting to ensure the pasting effect and position accuracy. The rotation of the rim 5 can also ensure the assembly accuracy of the valve. From the incoming materials to the end, it is an automatic line, without manual intervention, which greatly saves manpower and improves efficiency.

[0040] In summary, the rolling device provided in the present invention can play the role of side-by-side pasting and pressing, shortening the production cycle. From the incoming materials to the end, it is an automatic line, and no manual intervention is required, which greatly saves manpower and improves efficiency. The release paper can be separated before the input of the silent cotton, saving the time of removing the release paper during production. The automatic installation device for silent cotton can also rotate the rim according to the photo comparison to ensure the starting point device for installing the silent cotton, that is, it can start pasting from a predetermined position to ensure the accuracy of the pasting effect and position. The rotation of the rim can also ensure the assembly accuracy of the valve. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
