The highest lifting and transporting height of the roller mechanism 25 is higher than or flush with the upper plane of the upper layer transporting line, and the lowest lifting and transporting height is lower than or flush with the upper plane of the lower layer transporting line.

By providing the roller mechanism 25 on the lift reflow bracket 24, the roller mechanism 25 is able to horizontally accept or transport parts to an assembly line when the lift reflow bracket 24 transports the roller mechanism 25 flush with the assembly line. Specifically, when the roller mechanism 25 is transported flush with the lower assembly line 13 by the lifting/lowering reflow bracket 24, the components can be transported from the lower assembly line 13 to the roller mechanism 25; then the lifting power mechanism 23 drives the lifting backflow bracket 24 to move upwards through the lifting slide rail mechanism 22, and further transports the roller mechanism 25 to a position which is flush with the upper plane of the upper assembly line 12; then, the roller mechanism 25 moves horizontally again to transport the components on the roller mechanism 25 to the upper assembly line 12, so as to realize the reflow of the components on the assembly line equipment 1.

In summary, when the parts are carried to the assembly line facility 1, they are fed through the upper assembly line 12 or the lower assembly line 13, and then the parts are processed at the respective assembly stations by being transported through the assembly lines through the respective assembly stations.

two supporting beam bodies 14 which are fixed on two sides of the assembly line rack 11 in the width direction and are arranged in parallel with each other, wherein the two supporting beam bodies 14 are both of a hollow structure.

As shown in fig. 1 and 2, the supporting beam bodies 14 are disposed on both sides of the assembly line frame 11 in the width direction and are parallel to each other, and together form a supporting frame of the double-speed assembly line; the two support beams 14 are both hollow structures and used for carrying the speed-multiplying chain mechanisms 15, and the running space of the two speed-multiplying chain mechanisms 15 is also formed.

The two speed chain mechanisms 15 are respectively arranged in the supporting beam body 14 along the length direction of each supporting beam body 14.

The speed multiplying chain mechanism 15 is a mechanism for accelerating the running of parts. By applying the speed increasing function of the speed-multiplying chain, the tooling plate bearing the goods on the speed-multiplying chain mechanism 15 can obtain the speed far exceeding the speed of the speed-multiplying chain so as to run quickly.

Referring to fig. 6, the speed-multiplying chain mechanism 15 includes a large-caliber outer roller, a small-caliber inner roller, and a speed-multiplying chain sleeved on the periphery of the small-caliber inner roller, wherein the large-caliber outer roller is coaxially connected with the small-caliber inner roller. As shown in fig. 6, the double-speed chain mechanism 15 is designed such that the large-diameter outer roller and the small-diameter inner roller rotate in the same manner due to the friction generated therebetween, and the speed of the conveyed material is 2.5 times the speed of the chain in accordance with the ratio of the diameters of the rollers.

When the speed multiplication chain runs at the speed v, the peripheral speed of the periphery of the small-caliber inner roller (the rotating speed when the chain runs on the guide rail) is v. At this time, the large-caliber outer roller and the small-caliber inner roller rotate at the same angular velocity, so the peripheral velocity of the outer periphery of the large-caliber outer roller can be determined according to the formula: v₁Calculated as (R/R) × ν, wherein V₁The peripheral speed of the outer periphery of the large-caliber outer roller, R the radius of the large-caliber outer roller, R the radius of the small-caliber inner roller and v the peripheral speed of the outer periphery of the small-caliber inner roller.

Thus, the conveying speed V of the parts on the speed-multiplying chain mechanism 15₂Equal to the sum of the peripheral speed (R/R) x v of the outer roller and the chain speed v. The formula is as follows:

V₂(R/R) × ν + ν, i.e.: v₂＝(R/r+1)×ν。

By arranging the speed-multiplying chain mechanism 15, the transportation speed of the parts on the speed-multiplying chain mechanism 15 can be increased, and the assembly speed of the parts is increased. The speed-doubling chain mechanism 15 is provided along the longitudinal direction of the support beam body 14, and horizontal transportation of parts in the upper assembly line 12 and the lower assembly line 13 can be realized by transportation of the speed-doubling chain mechanism 15.
