Abstract
Description
Technical Field
[0001] The present invention relates to the fields of automobile manufacturing technology, logistics transportation, and the like, and in particular to a 90-degree flip EMS conveyor, which is suitable for handover stations where workpiece postures vary during transfer in automobile production lines and other industrial automation production lines. Background Art
[0002] In recent years, my country's production line equipment technology and market have experienced rapid development, with a rapid increase in the variety of conveying equipment and increasingly modernized conveying technology applications. Because EMS conveyors can operate in multiple stations within a single zone, achieve multiple operating positions such as left-right lateral movement and forward-backward swinging of workpieces, and are easily controlled, they are widely used in modern automotive pre-treatment electrophoresis production lines, where demand for increasingly complex and flexible processes is increasing.
[0003] Automotive pre-treatment electrophoresis lines often require the painted body to move horizontally and horizontally within the line, rise and fall vertically, and sway forward and backward. This means the body, carried by an EMS conveyor, can be moved in various positions within different workstations to meet production requirements. This functionality is primarily accomplished using a traveling trolley and front and rear hoist chains. EMS conveyors are primarily capable of handling complex workpiece positions during conveyance. Currently, commonly used EMS conveyors primarily feature a front-to-back lifting mechanism with either a front-to-back or left-to-right travel mechanism. During operation, a fixed overhead load rail serves as the lifting point for the spreader. Front and rear hoists, acting synchronously or asynchronously via chains, raise and lower the spreader, forming the lifting mechanism. This lifting mechanism primarily achieves its lifting function through the lifting of the hoists. In chain-lifting mechanisms, a hoist motor drives a turntable, which in turn drives a chain (with a chain storage bag beneath the turntable). The retraction and extension of the chain causes the conveyor to rise and fall vertically, while the asynchronous front and rear chains achieve the back-and-forth swing of the workpiece.
[0004] Conveying systems are a key component of automated production lines. The development of conveying system technology is showing trends toward intelligence, flexibility, lightweighting, energy conservation, and environmental friendliness. Across many industries, the demand for EMS conveying equipment with the same vertical and horizontal transfer capabilities varies significantly, depending on factors such as the shape and size of the conveying bodies, the length of the lift, the posture and swing angle of the bodies during the lift. Consequently, existing lifting mechanisms struggle to meet the diverse needs of these industries. Summary of the Invention

[0025] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0027] Example 1
[0028] like Figure 1-5 As shown, a 90-degree flip EMS conveyor includes a traveling device and a rotary drive device located below the traveling device. The traveling device includes a traveling trolley 105, which is mounted on a track via traveling wheels. The traveling wheels are driven by a traveling motor 104. An external sling frame 101 is provided below the traveling device, and the traveling device drives the external sling frame 101 to move horizontally.
[0029] A lifting mechanism is provided on the traveling device. In this embodiment, with the conveying direction of the track as the front and back, the lifting mechanism is respectively connected to the front and rear ends of the external spreader frame 101. The lifting mechanism includes two lifting hoists 103 arranged front and back above the external spreader frame 101. The lifting hoists 103 are connected to the external spreader frame 101 through a chain. When the two lifting hoists 103 rotate synchronously, the external spreader frame 101 is lifted. When the two lifting hoists 103 rotate asynchronously, the external spreader frame 101 is rotated in the front and back directions, and the rotation of the internal rotating spreader frame 102 is coordinated to further change the angle control of the vehicle body rotation.
[0030] An internal rotating sling frame 102 is mounted on the inner side of the external sling frame 101 via a rotating pin. The internal rotating sling frame 102 is provided with a sling and vehicle body positioning locking device 204. The worker fixes the vehicle body on the internal rotating sling frame 102 through the sling and vehicle body positioning locking device 204. The internal rotating sling frame 102 can drive the vehicle body to rotate while moving with the external sling frame 101, thereby performing the electrophoretic coating operation on the vehicle body, which saves space and is conducive to exhaust and drainage, avoiding the problem of bubbles in the vehicle body cavity.
[0031] The external sling frame 101 is provided with an internal and external sling locking device 203, which includes positioning holes provided on the external sling frame 101 and the internal rotating sling frame 102. The positioning holes are divided into external positioning holes provided on the external sling frame 101 and internal positioning holes provided on the internal rotating sling frame 102. A positioning pin is installed in the external positioning hole. When the internal rotating sling frame 102 is rotated to a predetermined position, the external positioning hole corresponds to the internal positioning hole. The staff inserts the positioning pin into the external positioning hole and the internal positioning hole to perform a secondary locking on the internal rotating sling frame 102. A detachable guardrail 205 is provided on the external sling frame 101. The guardrail 205 is a foldable guardrail for easy disassembly and assembly.
[0032] The conveyor further comprises a guide groove 106 and a travel guide wheel 206 or a guide pin cooperating with the guide groove 106. The travel guide wheel 206 or the guide pin is mounted on the external spreader frame 101. The guide groove is mounted above the external spreader frame 101 to make the external spreader frame 101 more stable when moving on the travel device.
[0033] The rotary drive device includes a rotary motor 208 that is arranged parallel to the axis of the rotary pin and is slidably installed along the axial direction. A coupling that cooperates with the rotary pin is installed on the output end of the rotary motor 208. After the internal rotary spreader frame 102 moves to a predetermined position, the rotary motor 208 and the rotary pin are located at a coaxial position. The rotary motor 208 is slid to connect the coupling with the rotary pin. The rotary motor 208 drives the rotary pin, which further drives the internal rotary spreader frame 102 to rotate.
[0034] The rotary drive device also includes a base frame 210, on which a rack traverse motor 209 is fixedly mounted. A rack meshing with a gear is mounted on the output end of the rack traverse motor 209, and the rack is mounted on the rotary motor 208. The rotary motor 208 is slidably mounted on the base frame 210 through a slider. The rack traverse motor 209 drives the rotary motor 208 to slide in a chute toward or away from the rotary pin through the gear rack.
[0035] A bottom guide rail 207 is provided on one side of the rotating drive device, and the bottom guide rail 207 is a vertical guide. A first guide wheel that cooperates with the bottom guide rail 207 is provided on the external sling frame 101. When the external sling frame 101 moves to a predetermined position, the lifting mechanism is controlled to lower the external sling frame 101 so that the first guide wheel enters the bottom guide rail 207 to fix the external sling frame 101 to prevent shaking. At the same time, when the first guide wheel enters the bottom guide rail 207, the rotating motor 208 and the rotating pin shaft are located in a coaxial position; it should be noted that the two lifting hoists 103 in the lifting mechanism can rotate asynchronously, thereby adjusting the external sling frame 101 to rotate to a specified angle in the front and rear directions. When the external sling frame 101 rotates to a specified angle in the front and rear directions, the bottom guide rail 207 can be installed according to the position of the first guide wheel after the external sling frame 101 rotates.
[0036] Working principle: When in use, the body is fixed in the internal rotating sling frame 102 through the sling and body positioning locking device 204, the walking device drives the external sling frame 101 to move to the predetermined position, and the lifting mechanism is controlled to lower the external sling frame 101. The first guide wheel enters the bottom guide rail 207, and at the same time, the rotating motor 208 and the rotating pin are located in a coaxial position. The rack transverse motor 209 is started to drive the rotating motor 208. After the rotating motor 208 is connected to the rotating pin through the coupling, the rack transverse motor 209 is self-locked, and the rotating motor 208 is started to drive the internal rotating sling frame 102 to rotate, that is, the body can achieve vertical lifting and horizontal continuous movement, the posture of the body in the sling is more diverse, and the electrophoresis process effect is more efficient.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
