Description

Hydrogen tank near-infrared heat welding device {HYDROGEN TANK NEAR INFRARED HEAT-MELTING}

The present invention relates to a near-infrared thermal fusion device for a hydrogen tank, and more particularly, a hydrogen tank that melts the bonding surfaces of a hydrogen tank manufactured separately into upper and lower parts with near-infrared rays and fuses them integrally so that the upper and lower parts can be quickly and firmly joined. It relates to a near-infrared thermal fusion device.

In recent years, fuel cell electric vehicles have been attracting attention in terms of the environment, such as suppressing the emission of carbon dioxide, which causes global warming. A fuel cell electric vehicle is equipped with a fuel cell that generates power by electrochemically reacting hydrogen and oxygen in the air, and generates driving force by supplying electricity generated by the fuel cell to a motor.

A hydrogen storage device for a fuel cell vehicle must be lightweight, highly efficient, and economical. As a hydrogen storage device that satisfies these conditions, a high-pressure gaseous hydrogen storage method using a composite pressure vessel is used, and research has been conducted to improve volumetric efficiency by increasing the working pressure. A hydrogen tank of a fuel cell vehicle uses an ultra-light composite tank in which a liner is reinforced with a carbon fiber/epoxy composite material, and these are divided into a tank using a metal liner and a tank using a non-metallic liner. A tank using a non-metal liner can reduce the weight of a container because it uses a non-metal liner such as plastic, unlike a composite material container with a metal liner. Due to the characteristics of the liner material, it has excellent environmental resistance and durability, so it is safe for long-term use and relatively inexpensive. You can make a liner for a price.

However, when a metal such as aluminum is used as a hydrogen tank liner, it has excellent gas barrier properties, but has a problem of absorbing hydrogen and causing brittle fracture due to low temperature. Further, when high-density polyethylene is used, airtightness is exhibited against natural gas having a large relative molecular weight, but there is a problem that gas barrier properties are inferior to hydrogen having a small molecular weight.

Therefore, it has been proposed to use various polymer materials with better gas barrier properties than high-density polyethylene as materials for the hydrogen tank liner. However, when a strong impact is applied to the hydrogen tank liner during use, cracks or the like cause gas leakage. Therefore, it is necessary to develop a polymer material having higher impact resistance in order to be used as a material for a hydrogen tank liner. In addition, attempts are being made to increase the mileage of fuel cell vehicles, etc., but when the internal pressure of the hydrogen tank becomes high at 70 MPa, the hydrogen tank becomes very low temperature during high-speed driving, so it has excellent mechanical properties even at extremely low temperatures of -40 ° C or lower. It is required to have physical properties and impact resistance.

Such a hydrogen tank is not integrally molded at once, but is manufactured with two or more separate parts and attached integrally. There are problems such as damage.

A process of integrally shaping a hydrogen tank made of upper and lower parts by the hydrogen tank near-infrared thermal fusion device of forward and reverse transfer heating method according to the first embodiment of the present invention configured as described above will be described.

First, with the upper fixture 120 located on the upper part and the lower fixture 220 located on the lower part, lift the upper end of the upper part of the hydrogen tank to align it with the upper fixture 120, and operate the electric control panel 900 to air chuck. 110, that is, when the air cylinder connected to the air chuck 110 is operated, the upper end of the upper part of the hydrogen tank is chucked to the air chuck 110 by the air pressure supplied from the air cylinder.

Subsequently, when the pair of guide cylinders 331 and 332 are driven by operating the electric control panel 900, the pair of clampers 311 and 312 together with the pair of guide cylinders 331 and 332 The upper part of the hydrogen tank is clamped on the side by advancing in opposite directions.

In addition, in order to fix the lower part of the hydrogen tank, after aligning the lower part of the lower part of the hydrogen tank with the lower fixture 220, the electric control panel 900 is operated to use the air chuck 210, that is, the air cylinder connected to the air chuck 210. When is operated, the lower end of the lower part of the hydrogen tank is chucked to the air chuck 210 by the air pressure supplied from the air cylinder.

Subsequently, when the pair of guide cylinders 431 and 432 are driven by operating the electric control panel 900, the pair of clampers 411 and 412 together with the pair of guide cylinders 431 and 432 The hydrogen tank lower part is clamped on the side by advancing in opposite directions.

In this way, after fixing the upper and lower parts of the hydrogen tank to the upper and lower fixtures 120 and 220, respectively, by operating the electric control panel 900 and operating the start switch to start the process of integrally molding the upper and lower parts, the servo motor 540 Driven, the near-infrared heating module 510 moves forward by 670 mm along the LM guide 520 at a speed of 200 mm/s to the space between the upper and lower parts of the hydrogen tank.

Subsequently, the servo motor 660 of the upper up-down unit 600 is driven so that the upper part of the hydrogen tank fixed to the upper fixture 120 descends by 85 mm at a speed of 50 mm/sec, and the servo motor 660 of the lower up-down unit 700 moves down. 760 is driven, and the lower part of the hydrogen tank fixed to the lower fixture 220 rises by 85 mm at a rate of 50 mm/sec, so that the welding surfaces of the upper and lower parts of the hydrogen tank are positioned close to the near infrared heating module 510. .

Next, when the electric control panel 900 is operated to drive the near-infrared heating module 510, the lower and upper parts of the upper and lower parts of the hydrogen tank are melted by the near-infrared heating module 510, respectively.

Here, since the 16 heating lamps (2KW) constituting the near infrared heating module 510 are arranged at 23 mm intervals, heat cannot be uniformly transferred to the upper and lower parts of the hydrogen tank due to the 23 mm interval, so the near infrared heating module 510 is set to 2.3 It heats while moving forward and backward at a rate of mm/sec.

At this time, the near-infrared heating module 510 moves forward by 11.5 mm, moves backward by 23 mm, and moves forward by 11.5 mm again.

After the welding surfaces of the upper and lower parts of the hydrogen tank are melted through the above process, pressure is applied to weld the upper and lower parts.

That is, the rotational force of the servomotor 660 is transmitted to the upper fixture 120 so that the upper part of the hydrogen tank descends by 36mm at a speed of 50mm/sec, and the rotational force of the servomotor 760 is transmitted to the lower fixture 220 to lower the hydrogen tank. After the tank lower part rises 36 mm at a rate of 50 mm/sec, once again the upper fixture 120 lowers 1 mm at a reduced rate of 1 mm/sec, and the lower fixture 220 lowers 1 mm at a reduced rate of 1 mm/sec. do.

At this time, the electric control panel 900 converts the servo control position control of the upper fixture 120 and the lower fixture 220 to torque control. That is, the electric control panel 900 lowers the upper fixture 120 and raises the lower fixture 220 to apply pressure until the welding surfaces of the upper and lower parts of the hydrogen tank reach a predetermined appropriate torque.

In addition, the upper fixture 120 and the lower fixture 220 do not descend or rise until the pressurization of the welding surfaces of the upper part of the hydrogen tank and the lower part of the hydrogen tank is stopped at an appropriate torque and the welded part is hardened. do.

Next, the electric control panel 900 cancels the chucking of the air chuck 110 of the upper fixing part 100 and the air chuck 210 of the lower fixing part 200, and the upper clamping part holding the upper part of the hydrogen tank. The clamping of the clampers 311 and 312 is released by driving the guide cylinders 331 and 332 of the 300.

In order to take out the integrally combined hydrogen tank, the upper fixture 120 rises 116 mm at a speed of 50 mm/sec and the lower fixture 220 descends 116 mm at a speed of 50 mm/sec under the control of the electric control panel 900, By driving the guide cylinders 431 and 432 of the lower clamping part 400 holding the lower part of the hydrogen tank to release the clamping of the clampers 411 and 412, the operator can take out the integrally fused hydrogen tank. there is.

Next, when the electric control panel 900 is operated to drive the near-infrared heating module 510, the lower and upper parts of the upper and lower parts of the hydrogen tank are melted by the near-infrared heating module 510, respectively.

Here, since the 16 heating lamps (2KW) constituting the near-infrared heating module 510 are arranged at 23 mm intervals, heat cannot be uniformly transferred to the upper and lower parts of the hydrogen tank due to the 23 mm interval, so the upper and lower fixtures 120 and 220 Heats while rotating the upper and lower parts of the hydrogen tank fixed to the

That is, the rotational force of the servomotors 830 and 840 for product rotation is transmitted to the upper and lower fixtures 120 and 222 to rotate the upper and lower parts of the hydrogen tank at a predetermined rotational speed for a predetermined time. At this time, the upper and lower clamping parts 300 and 400 are clampers 311, 312, 411, and 412 while the servo motors 830 and 840 for product rotation are driven to rotate the upper and lower parts of the hydrogen tank. ) to release the clamping of the upper and lower parts of the hydrogen tank.

After the melting process of the upper and lower parts of the hydrogen tank by the near-infrared heating module 510 is performed for a predetermined time, the upper fixture 120 rises by 5 mm at a speed of 50 mm/sec to move the near-infrared heating module 510 backward. And, the lower fixture 220 descends 5 mm at a speed of 50 mm/sec.

Subsequently, the server motor 540 is driven so that the near-infrared heating module 510 moves backward by 670 mm at a speed of 200 mm/sec and moves to its original position.

After the welding surfaces of the upper and lower parts of the hydrogen tank are melted through the above process, pressure is applied to weld the upper and lower parts.

That is, the rotational force of the servomotor 660 is transmitted to the upper fixture 120 so that the upper part of the hydrogen tank descends by 36mm at a speed of 50mm/sec, and the rotational force of the servomotor 760 is transmitted to the lower fixture 220 to lower the hydrogen tank. After the tank lower part rises 36 mm at a rate of 50 mm/sec, once again the upper fixture 120 lowers 1 mm at a reduced rate of 1 mm/sec, and the lower fixture 220 lowers 1 mm at a reduced rate of 1 mm/sec. do.

At this time, the electric control panel 900 converts the servo control position control of the upper fixture 120 and the lower fixture 220 to torque control. That is, the electric control panel 900 lowers the upper fixture 120 and raises the lower fixture 220 to apply pressure until the welding surfaces of the upper and lower parts of the hydrogen tank reach a predetermined appropriate torque.

In addition, the upper fixture 120 and the lower fixture 220 do not descend or rise until the pressurization of the welding surfaces of the upper part of the hydrogen tank and the lower part of the hydrogen tank is stopped at an appropriate torque and the welded part is hardened. do.

Next, the electric control panel 900 cancels the chucking of the air chuck 110 of the upper fixing part 100 and the air chuck 210 of the lower fixing part 200, and the upper clamping part holding the upper part of the hydrogen tank. The clamping of the clampers 311 and 312 is released by driving the guide cylinders 331 and 332 of the 300.

In order to take out the integrally combined hydrogen tank, the upper fixture 120 rises 116 mm at a speed of 50 mm/sec and the lower fixture 220 descends 116 mm at a speed of 50 mm/sec under the control of the electric control panel 900, By driving the guide cylinders 431 and 432 of the lower clamping part 400 holding the lower part of the hydrogen tank to release the clamping of the clampers 411 and 412, the operator can take out the integrally fused hydrogen tank. there is.
