Description

Technical Field

[0001] This utility model relates to the field of tire tube valve technology, specifically an automatic assembly device for tire tube valves. Background Technology

[0002] As an independent valve body device, the valve has important applications in modern life, such as in the tires of bicycles, motorcycles, electric vehicles, cars, trucks, buses, agricultural and engineering vehicles. When the valve opens, it allows gas to enter the space of the tubeless tire or inner tube, and then automatically closes and seals to retain the gas and generate air pressure to prevent gas from escaping from the tire or inner tube. The valve consists of a valve body and an air core. When the air core is installed inside the valve body, it is generally screwed in or pressed in.

[0003] Currently, valve bodies and valve cores require manual placement during installation, which is inefficient. Alternatively, robotic arms can be used, but one set of robotic arms reduces assembly efficiency during the picking and placing process, while setting up two sets of robotic arms is too costly. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic assembly device for tire tube valves, which solves the problems of low efficiency when valve housings and valve cores need to be placed by workers during installation, or the low efficiency when a robotic arm is used, which reduces assembly efficiency during the picking and placing process, and the high cost of setting up two robotic arms.

[0005] This application provides an automatic assembly device for tire tube valves, including a worktable. A circular hole is provided on the upper side of the worktable. A working cylinder is fixedly installed on the upper end of the worktable above the circular hole. An inlet hole is provided on the outer wall below the working cylinder. Conveying mechanisms for clamping and conveying air core components are respectively provided on the upper ends of the worktable on both sides of the inlet hole. A U-shaped frame is fixedly installed on the lower end of the worktable below the circular hole. An electric push rod is fixedly installed on the upper end of the U-shaped frame. A stop post is fixedly installed on the telescopic end of the electric push rod. An L-shaped frame is fixedly installed on the upper end of the worktable on one side of the working cylinder. A hydraulic rod is installed in the inner wall of the L-shaped frame. The telescopic end of the hydraulic rod corresponds to the side of the working cylinder. An adsorption and pressure mechanism is provided above the L-shaped frame.

[0006] By adopting the above technical solution, two sets of conveying mechanisms are used to convey the valve housing and valve core. The valve housing can be directly conveyed into the inlet hole. In the conveying mechanism, the latter valve housing will push the former valve housing into the working cylinder. Then, the electric push rod drives the abutment column to move vertically. The abutment column drives the valve housing to move vertically. Then, the adsorption and pressing mechanism can adsorb the valve core and press it into the valve housing. After the valve nozzle is installed, the hydraulic rod pushes the valve nozzle to unload, thereby reducing the material loading and unloading time and speeding up the installation efficiency of the valve nozzle.

[0007] Optionally, each of the two sets of conveying mechanisms includes two sets of vertical plates. The two sets of vertical plates are fixedly installed on the upper end of the workbench. A fixing plate is fixedly installed on the opposite side of the two sets of vertical plates. A conveying roller is rotatably installed on the opposite side of each fixing plate and the workbench. A conveyor belt is drivenly installed on the outer wall of each set of conveying rollers.

[0008] By adopting the above technical solution, the workbench can fix the vertical plate, the vertical plate can fix the fixed plate, the fixed plate and the workbench can provide rotational support for the conveyor roller, and the conveyor roller and the conveyor belt can transport the air core and valve shell.

[0009] Optionally, two sets of housings are fixedly installed at the lower end of the worktable. Each set of housings is rotatably mounted with a set of gears on the inner wall of the worktable. Each set of gears meshes with each other. The gears are fixedly connected to the corresponding conveyor rollers. A drive motor is installed at the lower end of each housing. The output shaft of the drive motor is fixedly connected to the gear.

[0010] By adopting the above technical solution, the workbench can fix the shell, and the shell and workbench can provide rotational support for the gear. The shell can also enclose the gear, ensuring the safety of the workers. The drive motor can drive the gear to rotate, and the gear can drive the conveyor roller to rotate.

[0011] Optionally, the adsorption and pressure mechanism includes two fixed blocks, which are respectively fixedly installed on the inner top wall of the L-shaped frame. A lead screw is rotatably installed on one side of the two fixed blocks that are opposite to each other. A threaded block is threaded on the outer wall of the lead screw, and the threaded block is slidably connected to the inner top wall of the L-shaped frame.

[0012] By adopting the above technical solution, the L-shaped frame can fix the fixed block, and the fixed block can provide rotational support for the lead screw. When the lead screw rotates, it can drive the threaded block to move.

[0013] Optionally, a reciprocating motor is mounted on the outer wall of one of the fixed blocks, and the output shaft of the reciprocating motor is fixedly connected to a lead screw.

[0014] By adopting the above technical solution, the fixing block can fix the reciprocating motor, and the reciprocating motor can drive the lead screw to rotate back and forth.

[0015] Optionally, a cylinder is fixedly installed on the outer wall of the threaded block, an installation block is fixedly installed on the telescopic end of the cylinder, and an electromagnet ring is fixedly installed on the lower end of the installation block. The position of the electromagnet ring corresponds to that of one of the conveying mechanisms and the working cylinder.

[0020] By adopting the above technical solution, the support legs can provide support for the workbench.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses two sets of conveying mechanisms to transport the valve housing and valve core. The valve housing can be directly transported into the inlet hole. In the conveying mechanism, the latter valve housing pushes the former valve housing into the working cylinder.

[0033] In the technical solution of this utility model, two sets of conveying mechanisms are used to convey the valve housing and the valve core. The valve housing can be directly conveyed into the inlet hole 3. In the conveying mechanism, the latter valve housing will push the former valve housing into the working cylinder 2. Then, the electric push rod 6 drives the abutment 4 to move vertically. The abutment 4 drives the valve housing to move vertically. Then, the adsorption and pressing mechanism can adsorb the valve core and press it into the valve housing. After the valve nozzle is installed, the hydraulic rod 20 pushes the valve nozzle to unload, thereby reducing the loading and unloading time and speeding up the installation efficiency of the valve nozzle.

[0034] In addition, the L-shaped frame 12 can fix the fixing block 13, and the fixing block 13 can provide rotational support for the lead screw 14.

[0035] In the technical solution of this utility model, such as Figure 1 and Figure 4 As shown, a guide shell 25 is fixedly installed on the outer wall of the working cylinder 2 away from the L-shaped frame 12. The guide shell 25 is inclined and can be fixed by the working cylinder 2. The guide shell 25 can guide the air nozzle to feed the material. Multiple sets of support legs 24 are fixedly installed at the lower end of the worktable 1. The support legs 24 can support the worktable 1.

[0036] In the technical solution of this utility model, such as Figures 1-5As shown, the two conveying mechanisms each include two sets of vertical plates 8, which are fixedly installed on the upper end of the workbench 1. A fixing plate 9 is fixedly installed on the opposite side of each set of vertical plates 8.

The workbench 1 can fix the vertical plates 8, and the vertical plates 8 can fix the fixing plates 9. The fixing plates 9 and the workbench 1 provide rotational support for the conveying rollers 10. The conveying rollers 10 and the conveyor belt 11 work together to convey the air core and valve housing. The lower end of the workbench 1 is fixed... Two sets of housings 23 are installed. Each set of housings 23 and the inner wall of the workbench 1 are respectively rotatably mounted with a set of gears 21. Each set of gears 21 meshes with each other and is fixedly connected to the corresponding conveyor roller 10. Each housing 23 is equipped with a drive motor 22 at its lower end. The output shaft of the drive motor 22 is fixedly connected to the gear 21. The workbench 1 can fix the housing 23, and the housing 23 and the workbench 1 can provide rotational support for the gear 21.

[0037] In use, two sets of drive motors 22 drive gears 21 to rotate, which in turn drive conveyor rollers 10 to rotate. The conveyor rollers 10 and conveyor belts 11 work together to clamp and convey the valve housing and valve core. The conveying end of the valve housing corresponds to the position of the inlet hole 3, allowing the valve housing to be directly conveyed into the inlet hole 3. Between each set of conveyor belts 11, the next valve housing pushes against the previous valve housing and enters the working cylinder 2. Then, the electric push rod 6 drives the abutment 4 to move vertically, and the abutment 4 drives the valve housing to move vertically. The reciprocating motor 15 drives the lead screw 14 to rotate back and forth, and the threaded block 16 drives the cylinder 17 to move. The electromagnet ring 19 below the cylinder 17 can attract the air core, making it easier for the electromagnet ring 19 to be pressed into the valve housing. Then the air nozzle is assembled, the abutment 4 rises, and the hydraulic rod 20 pushes the air nozzle to be unloaded. At this time, the valve housing is being transported, while the abutment 4 descends, making it easier for the valve housing to enter the working cylinder 2. At this time, the electromagnet ring 19 can also attract the material, thus speeding up the assembly of the air nozzle.
