Description

Technical Field

[0001] The invention relates to the field of conveying equipment, and more particularly to an assembly line for charging automobiles. Background Art

[0002] There are three main types of charging lines for cars in existing automobile assembly workshops:

[0003] The first is to use an ordinary hanging conveyor to hang the charging tray and run it synchronously with the production line. This form cannot adjust the spacing between the charging trays. Since the spacing between cars in the production line is uncertain, it cannot guarantee that the cars in front and behind the charging tray can be reliably charged. In addition, since the spacing between the charging trays is fixed, the number of charging trays will increase, which will increase the production and operation costs.

[0004] The second method is to use a non-powered track and a cart chain. This method requires a synchronous chain to push the charging tray. In addition to setting up a quick return line, the charging tray cannot be stored. The charging tray has no power before entering the charging station, and manual operation is inconvenient.

[0005] The third method is to use a light-duty accumulation conveyor to hang the charging pallet and run it synchronously with the production line. The existing light-duty accumulation conveyors are relatively large in size and complex in structure, and cannot achieve the slow operation of the charging pallet synchronous with the production line when charging, and the rapid return of the charging pallet after charging is completed.

[0006] Therefore, how to provide a charging line for automobiles that can overcome the above-mentioned problems is an issue that those skilled in the art urgently need to solve. Summary of the invention

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention discloses an assembly line for charging cars. The present invention sets a slow conveying line and a fast return line, and a stacking trolley equipped with a charging tray 1 can run on the slow conveying line and the fast return line. The above setting ensures that the charging tray 1 can be accumulated on the slow conveying line, and the spacing of the charging tray 1 can be adjusted to adapt to different charging spacings. At the same time, the charging tray 1 can quickly return through the fast return line after charging is completed; in the present invention, a revolving bearing rail 13 and a trolley turntable 14 are set, so that the car body can walk on the slow bearing rail 8, the fast bearing rail 12 and the two revolving bearing rails through the wheels 19. The closed load-bearing track 13 is formed by the accumulation sprocket 20 and the slow traction chain 6 or the fast traction chain 10. When the accumulation sprocket 20 is out of mesh with the slow traction chain 6 or the fast traction chain 10, the push teeth 15 on the trolley turntable 14 can push the car body to move along the rotary load-bearing track 13 to ensure the continuity of the car body operation. The two trolley turntables 14 are both connected to the dual-output shaft reduction motor 2 in transmission, and there is no need to design a separate drive device to drive the trolley turntable 14, which further simplifies the structure and reduces the failure rate and installation and maintenance costs. The accumulation trolley adopts the friction between the friction ring 1 22 and the friction ring 2 23 to achieve accumulation. The structure is simple and reliable and is suitable for the transportation and accumulation of small weight objects.

[0041] See attached Figure 1-11 The overall and partial structural schematic diagram of an embodiment of the present invention specifically discloses an assembly line for charging a car, on which a charging tray 1 for charging a car is running, including:

[0042] A driving device, the driving device having a low speed output end and a high speed output end;

[0043] Slow conveyor line, the slow conveyor line includes a slow traction chain 6, a slow traction track 7, a slow load-bearing track 8 and a stopper 9, the slow traction chain 6 is transmission-connected to the low-speed output end, the slow traction chain 6 travels on the slow traction track 7 through the chain travel wheel, the slow load-bearing track 8 is arranged along the slow traction track 7 and is limited directly below the slow traction track 7, and the stopper 9 is arranged on one side of the slow load-bearing track 8 to realize the accumulation of the accumulation trolley;

[0044] A fast return line, the fast return line includes a fast traction chain 10, a fast traction track 11 and a fast load-bearing track 12. In addition, the fast return line may also include a stopper 44, which is arranged on one side of the fast load-bearing track 12 and is used to store the accumulation trolley on the fast load-bearing track. The fast traction chain 10 is transmission-connected to the high-speed output end, and the fast traction chain 10 travels on the fast traction track 11 through the chain running wheel. The fast load-bearing track 12 is arranged along the fast traction track 11 and is limited directly below the fast traction track 11. The stopper 9 and the stopper 44 have the same structure and both belong to the prior art, so they will not be specifically described in this embodiment;

The traction segment 1 is arranged lower than the separation segment 1 and the two have a smooth inclined transition. The two separation segments 1 correspond to the positions of the two rotary bearing tracks 13 respectively.

[0047] The fast traction track 11 includes a traction section 2 and two separation sections 2. The traction section 2 is limited between the two separation sections 2. The traction section 2 is arranged lower than the separation section 2 and the two have a smooth inclined transition. The two separation sections 2 correspond to the positions of the two rotary bearing tracks 13 respectively.

[0048] Two cart turntables 14 are horizontally arranged and each is limited on the inner side of two rotating bearing rails 13. Both cart turntables 14 are transmission-connected to the high-speed output end. Two push teeth 15 are installed on the outer side wall of each cart turntable 14.

[0049] The accumulation trolley includes a vehicle body, wheels 19 and accumulation components. The wheels 19 are installed on the vehicle body, and a charging tray 1 is fixed under the vehicle body. The vehicle body can travel on a closed load-bearing track composed of a slow load-bearing track 8, a fast load-bearing track 12 and two rotary load-bearing tracks 13 through the wheels 19. The end of the vehicle body can abut against the baffle of the stopper 9, the baffle of the stopper 44, and the push tooth 15.

[0050] The accumulation component is installed on the vehicle body, and the accumulation component includes an accumulation sprocket 20. The slow traction chain 6 and the fast traction chain 10 can both engage with the accumulation sprocket 20. The slow traction chain 6 and the fast traction chain 10 can both drive the vehicle body to move through the accumulation sprocket 20. When the accumulation sprocket 20 corresponds to the position of the separation segment 1 or the separation segment 2, the accumulation sprocket 20 has a gap with the separation segment 1 and the separation segment 2 respectively.

[0051] When the accumulation sprocket 20 is limited below the traction section 1 or the traction section 2, the accumulation sprocket 20 can engage with the slow traction chain 6 or the fast traction chain 10.

[0052] To be more specific, the accumulation component also includes an accumulation shaft 21, a friction ring 1 22, a friction ring 23, a pressure cover 24, a spring 25 and a clamping nut 26.

The cylindrical shaft portion is penetrated by the through hole 1, and the milled flat shaft portion is slidably penetrated by the through hole 2. The accumulation sprocket 20, the friction ring 1 22, the friction ring 23, the pressure cover 24 and The spring 25, the accumulation sprocket 20, the friction ring 1 22 and the friction ring 23 are all limited between the through hole 1 and the through hole 2.

The two ends of the spring 25 are respectively in contact with the pressure cover 24 and the clamping nut 26, and the friction ring 1 22 is in contact with the friction ring 23.

[0053] By screwing the clamping nut 26, the accumulation shaft 21 and the accumulation sprocket 20 can be displaced in the direction of the clamping nut 26, so that the friction ring 1 22 and the friction ring 2 23 abut. By tightening the clamping nut 26, the friction between the friction ring 1 22 and the friction ring 2 23 increases. When the slow traction chain 6 or the fast traction chain 10 is running, it can drive the accumulation sprocket 20 to move. When the baffle of the stopper 1 9 or the stopper 2 44 is extended and abuts against the front anti-collision block, due to the continuous operation of the slow traction chain 6 or the fast traction chain 10, the accumulation sprocket 20 overcomes the friction between the friction ring 1 22 and the friction ring 2 23 and starts to rotate, and the vehicle body stops moving, thereby achieving the stop of the vehicle body; when the baffle of the stopper 1 9 or the stopper 2 44 is retracted, due to the friction between the friction ring 1 22 and the friction ring 23, the accumulation sprocket 20 stops rotating, and the slow traction chain 6 or the fast traction chain 10 drives the accumulation sprocket 20 to move again.

[0054] To be more specific, the accumulation trolley further includes a front anti-collision block and a rear anti-collision block, which are respectively fixed at both ends of the vehicle body, the front anti-collision block can abut against the baffle of stopper 9 or stopper 2 44, and the rear anti-collision block can abut against the push tooth 15. The front anti-collision block on one accumulation trolley can abut against the rear anti-collision block on another adjacent accumulation trolley.

[0055] To be more specific, the vehicle body includes a connecting plate 16, a connecting plate 17 and a connecting shaft 18. The connecting plate 16 and the connecting plate 17 are arranged in parallel and are jointly penetrated by two connecting shafts 18. The connecting plate 16 and the connecting plate 17 are both limited between the two ends of the connecting shaft 18. The two connecting shafts 18 are arranged in parallel, and both ends of each connecting shaft 18 are rotatably connected to a wheel 19.

[0061] More specifically, it also includes a mounting plate 41, a pin 42 and a tension spring 43. Two notches 140 are provided on the side wall of the cart turntable 14. Two mounting plates 41 are respectively fixed on the upper and lower disk surfaces of the cart turntable 14. The four mounting plates 41 correspond to each other in the upper and lower positions. The two mounting plates 41 at the corresponding positions are connected by a pin 42. A pin 42 is limited in each notch 140. The push tooth 15 is wedge-shaped as a whole and is provided with two. A push tooth 15 is limited between each two mounting plates 41 corresponding to the upper and lower positions. A hole is opened on the plate surface of the push tooth 15 away from the sharp end thereof and a pin 42 is sleeved thereon. One end of the tension spring 43 is fixed to the disk surface of the cart turntable 14, and the other end is fixed to the push tooth 15.

[0062] When the cart turntable 14 rotates in a certain direction, one side wall of the push tooth 15 abuts against one side wall of the notch 140.

As the cart turntable 14 rotates, the push tooth 15 rotates around the pin shaft 42, the distance of the tension spring 43 becomes longer, and the push tooth 15 cannot push the vehicle body to move.

[0063] A charging tray 1 is connected under the vehicle body. When the vehicle body runs on the slow-speed load rail 8, the vehicle body is accumulated through a stopper 9, so as to adjust the position of the charging tray 1 and the interval between the front and rear charging trays 1 to ensure that the charging tray 1 can charge the vehicles in front and behind it;

[0064] The car body moves on the slow load-bearing track 8. When the car body runs to the inclined transition position where the traction section 1 is connected to the separation section 1, the accumulation sprocket 20 is separated from the slow traction chain 6. At this time, the car body is no longer driven by the slow traction chain 6, and the cart turntable 14 corresponding to the position of the separation section 1 begins to push the car body to move along the revolving load-bearing track 13 corresponding to the position of the traction section 1; when the car body runs to the inclined transition position where the separation section 2 is connected to the traction section 2, the accumulation sprocket 20 begins to engage with the fast traction chain 10, and the cart turntable 14 corresponding to the position of the traction section 1 no longer pushes the car body to move. At this time, the car body starts to move along the fast load-bearing track 12; the process of the car body running from the fast load-bearing track 12 to the slow load-bearing track 8 is similar to the above process, so it will not be described in detail.
