Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a transfer device for separating the EMS trolley from the lifting device in the storage area of ​​the reverse roller bed. Background Technology

[0002] In the existing production process of automotive welding workshops, door and side panel workpieces are typically transported from one workstation to the next via conveyor trolleys on EMS aluminum rail conveyor lines. Most automotive welding workshops need to accommodate the production of multiple vehicle models on the same line, therefore, workpieces such as door and side panel workpieces require a storage area during production. Since the lifting fixtures used to suspend workpieces in most automotive plants are inseparable from the EMS trolleys in current technology, the storage area in the workshop mostly uses EMS aluminum rails as the storage line. Each stored workpiece requires a set of EMS trolleys and lifting fixtures. This occupies a large space, requires a large investment, and results in a small number of workpieces stored within the same factory area. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the existing technology and provide a transfer device for separating the lifting device from the EMS trolley and the lifting device in the reverse roller bed storage area. The lifting device and the EMS trolley can be separated; the overall structure is stable: the stability of the structure is achieved through a symmetrical fixed frame; the vertical lifting stop position is accurate; the operation is stable; the operation speed is fast; and the structure is simple.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] This utility model provides a transfer device for separating the lifting device between the EMS trolley and the storage area of ​​the reverse lifting roller bed, including: a fixed frame assembly, a lifting drive assembly, a left lifting roller bed assembly, a right lifting roller bed assembly, and a gap detection assembly;

[0006] The fixed frame assembly is used to fix the entire device below the primary beam of the steel structure in the first workshop; the fixed frame assembly includes: a horizontal frame, diagonal braces, and a vertical frame; the horizontal frame is fixed below the primary beam of the steel structure in the first workshop, the vertical frame is connected to the diagonal braces, and the vertical frame is installed below the horizontal frame; ensuring the integrity of the frame, while ensuring the horizontality of the horizontal frame and the perpendicularity of the vertical frame to the horizontal frame;

[0007] The lifting drive assembly includes: a lifting drive motor, a double-row drive sprocket, and a lifting module. The lifting drive motor is mounted on a vertical frame, and the double-row drive sprocket is mounted on the output shaft of the lifting drive motor. The double-row drive sprocket drives the lifting module to lift the lifting roller assembly.

[0008] The left and right lifting roller bed assemblies use lifting actions to detach the suspended sled from the EMS trolley, or to detach the suspended sled from under the EMS trolley for suspension; the suspended sled is horizontally transported and stored via rollers, or the suspended sled in the reverse roller bed storage area is horizontally transported to the transfer position to realize the picking function; the reverse roller bed is located below the reverse roller bed hanger, which is located below the primary beam of the steel structure in the second workshop;

[0009] The left and right lifting roller bed assemblies are symmetrical components; all the parts used are identical or symmetrical; both the left and right lifting roller bed assemblies include: a drag chain mounting plate, a safety wire rope, a maintenance locking pin module, a lifting module, and a roller bed module.

[0010] The lifting module includes: a lifting detection sensor, a first guide bar, a second guide bar, a roller, a first lifting scale, a second lifting scale, a first lifting pointer, a second lifting pointer, a first lifting slide rail, a second lifting slide rail, and a lifting slider; the first guide bar is the side guide bar for horizontal transport of the suspended sled on the roller bed, and the second guide bar is the side guide bar for horizontal transport of the suspended sled on the EMS trolley into the transfer device;

[0012] The gap detection component includes a gap detection bracket, a photoelectric sensor, and a reflector, used to detect whether the sled has completely left the lifting roller bed during horizontal transport. Lifting or lowering can only be performed when it has completely left the roller bed; otherwise, it cannot be performed.

[0013] Furthermore, the horizontal frame is fixed below the primary beam of the steel structure in the first workshop by a mounting plate, and the vertical frame is connected to the diagonal brace by bolts.

[0014] Furthermore, the driving double-row sprocket includes: a double-row chain, a steering sprocket, and a driven sprocket. The double-row chain, through the steering sprocket, ultimately drives the driven sprocket to drive the lifting drive shaft.

[0015] Furthermore, the lifting module is a crank-connecting rod module, comprising: a lifting drive shaft, a lifting crank, a spherical bearing, and a lifting connecting rod. The driving double-row sprocket drives the lifting drive shaft, which in turn drives the lifting roller assembly to rise and fall via the lifting crank, the spherical bearing, and the lifting connecting rod. A tightening bolt is provided on the lifting crank.

[0016] Furthermore, the maintenance locking pin module includes: a maintenance pin hole and a maintenance pin.

[0017] Furthermore, due to different installation locations, some components are installed on the left and right lifting roller beds respectively. The left lifting roller bed assembly is also equipped with a frequency converter and an end dead stop.

[0021] Furthermore, the EMS trolley is mounted on the EMS aluminum rail C-shaped hook, and the EMS aluminum rail C-shaped hook is also equipped with a cable tray bracket.

[0022] Working principle:

[0023] This invention, through the combination of an EMS trolley, a reverse-suspension roller bed storage area, and a suspended sled, enables the suspended sled to be stored separately from the EMS trolley and retrieved when needed.

[0024] During the sled storage process, when the left and right lifting roller bed assemblies are in the low position, the EMS trolley transports the suspended sled to the transfer position, and then the lifting action is performed to detach the suspended sled from the EMS trolley. The suspended sled is then horizontally transported on the roller bed perpendicular to the EMS track direction. After the suspended sled leaves, the EMS trolley drives away from the transfer position, thus realizing the independent storage of the suspended sled detached from the EMS trolley.

[0025] When the EMS trolley retrieves the suspended sled from the reverse roller bed storage area, it performs a reverse operation. The empty EMS first moves to the grab position, the left and right lifting roller bed assemblies rise to the high position, and then the suspended sled is transported from the reverse roller bed storage area to the transfer device roller bed. Then the left and right lifting roller bed assemblies fall to the low position, hooking the suspended sled under the EMS trolley. Then the EMS trolley drives away with the suspended sled, and the retrieval is completed.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] (1) The lifting device and the EMS trolley can be separated. This meets the needs of multi-model co-production.

[0028] (2) Overall structural stability: The stability of the structure is achieved through a symmetrical fixed frame.

[0029] (3) Accurate vertical and horizontal stopping positions: The lifting mechanism is a crank-connecting rod-slider mechanism, which is finely adjusted by joint bearings. The vertical and horizontal stopping positions are dead points, ensuring the accuracy of the vertical and horizontal stopping positions.

[0030] (4) Stable operation: The overall structure of the transfer device is symmetrical, and there is no relative movement of the horizontal mechanism except for the conveying component, so the center of gravity is relatively stable.

[0031] (5) Fast operation: The lifting action only requires the drive shaft to rotate half a turn, which takes about 2 seconds. When the roller bed is conveyed horizontally, it relies on the friction between the rubber-coated roller and the sled for conveying. The speed can reach 15m / min. The sled length is 880mm, and the conveying length is 1240mm when it is being rotated. It only takes 5 seconds, which can realize relatively fast storage and retrieval of sleds.

[0032] (6) Simple structure: The overall structure consists only of a crank connecting rod slider mechanism and a horizontal conveying roller bed. The structure is simple, reliable, easy to install and maintain. Attached Figure Description
