Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an RGV shuttle. Background Technology

[0002] RGV (Automated Guided Vehicle) trolleys are intelligent vehicles that run along tracks and can connect multiple processing stations within a workshop. They can transport workpieces from one station to the next, completing the workpiece transfer process for the entire production line. Generally, RGV trolleys are relatively easy to position at processing stations when transporting small items, but the heavier the item, the more difficult it becomes to position the RGV. While existing RGV trolleys can transport goods, they cannot automatically pick up and place heavy items if the location where the goods are placed lacks automatic loading / unloading capabilities, affecting their usability. Furthermore, existing RGV trolleys suffer from poor loading stability, are prone to slipping during transport, and have low loading and unloading efficiency.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses an RGV trolley [CN201910859027.9], which includes a track, a trolley body mounted on the track, a drive device mounted at one end of the trolley body, a lifting device mounted in the middle of the trolley body, a multi-stage fork assembly mounted above the lifting device, a hydraulic device mounted at the end of the trolley body away from the drive device, a lateral positioning device mounted below the lifting device on the trolley, multiple positioning plates mounted on both sides of the track and cooperating with the lateral positioning device, and a communication device for controlling the movement of the trolley body.

[0004] The above solution has solved the problem of RGV trolleys being unable to accurately position the processing station in the existing technology to a certain extent. However, the solution still has many shortcomings, such as poor loading stability, easy slippage during the process, and low loading and unloading efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an RGV shuttle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an RGV shuttle, comprising a frame body, drive wheels at the bottom of both ends of the frame body, assembly positioning plates at both ends of the frame body, forming a workpiece loading gap between the assembly positioning plates, a drive guiding mechanism inside the frame body for driving the drive wheels to rotate on the guide rail groove on the ground to realize the movement of the frame body, a workpiece in-and-out conveying structure inside the workpiece loading gap, and a workpiece positioning component circumferentially provided in the workpiece loading gap, the workpiece in-and-out conveying structure being driven by a conveying drive mechanism provided inside the frame body.

[0007] In the aforementioned RGV shuttle, the two sides of the frame body are closed by sealing plates. The sealing plates and the assembly positioning plate form a circumferential wrap around the frame body, and the outer wall of the assembly positioning plate is provided with several polyurethane buffers.

[0008] In the aforementioned RGV shuttle, the workpiece in-and-out conveying structure includes several workpiece support end plates disposed within the workpiece loading gap and located on the upper end face of the frame body, and a conveying roller assembly is provided between two adjacent workpiece support end plates.

[0009] In the aforementioned RGV shuttle, an auxiliary conveying support rod is provided between the conveying roller assembly and the workpiece support end plates located on both sides, and auxiliary rollers are provided at both ends of the auxiliary conveying support rod.

[0010] In the aforementioned RGV shuttle, the conveying drive mechanism includes a conveying drive motor disposed within the frame body. The output end of the conveying drive motor is connected to a linkage shaft disposed on the frame body via a linkage pulley. Both ends of the linkage shaft are connected to the end of one of the conveying rollers in the conveying roller assembly via a linkage drive belt.

[0011] In the aforementioned RGV shuttle, the workpiece positioning assembly includes a workpiece guide plate disposed at both ends of the workpiece loading gap and in contact with the assembly positioning plate, and a blocking mechanism is provided at both ends of the workpiece support end plate located in the middle. In the aforementioned RGV shuttle, the blocking mechanism includes a clearance through-hole disposed on the workpiece support end plate, a blocking plate connected to the clearance through-hole via a rotating lifting seat, rollers disposed at both ends of the blocking plate, and auxiliary conveying rollers disposed on both sides of the clearance through-hole, with the auxiliary rollers and auxiliary conveying rollers located on the same axis.

[0012] In the aforementioned RGV shuttle, the bottom of the rotating lifting seat is connected to a rotating drive linkage via a linkage support rod. The two ends of the rotating drive linkage are rotated and positioned via rotating connecting seats set on the frame body. A pressing drive motor is installed inside the frame body, and the pressing drive motor is connected to the linkage wheel on the rotating drive linkage via a linkage belt.

[0013] In the aforementioned RGV shuttle, the drive and guide mechanism includes a rotary drive motor disposed within the frame body, a linkage gear disposed at the output end of the rotary drive motor, the linkage gear being connected to the drive shaft via a linkage chain, and drive wheels disposed at both ends of the drive shaft. A horizontally disposed guide wheel is disposed at the bottom of the frame body, the guide wheel contacting the inner wall of a guide rail groove disposed on the ground, and the drive wheel being disposed within the guide rail groove.

[0014] In the aforementioned RGV shuttle, a laser rangefinder is installed on the assembly positioning plate at one end of the frame body, and an optical communication module is installed on the assembly positioning plate at the other end of the frame body.

[0015] Compared with the prior art, the advantages of this utility model are as follows: By setting workpiece guide plates and blocking mechanisms in the circumferential direction of the workpiece loading gap, the workpiece is constrained in the circumferential direction, which limits the lateral and longitudinal displacement of the workpiece during the movement of the RGV and avoids slippage. Secondly, the polyurethane buffer on the outer wall of the assembly positioning plate absorbs the impact when the RGV docks with the loading and unloading station, reducing the shaking of the workpiece caused by the collision and improving the stability during transportation and start-up and shutdown. The workpiece in-and-out conveying structure adopts a conveying roller group in combination with auxiliary rollers and auxiliary conveying support rods to form a multi-point supported rolling conveying surface, which greatly reduces the frictional resistance between the workpiece and the conveying surface and speeds up the loading and unloading of the workpiece.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figs. 1-3As shown, an RGV shuttle includes a frame body 1, with drive wheels 11 at the bottom of both ends of the frame body 1, and assembly positioning plates 12 at both ends of the frame body 1, forming a workpiece loading gap 13 between the assembly positioning plates 12. A drive guide mechanism 2 is provided inside the frame body 1 to drive the drive wheels 11 to rotate on the guide rail groove on the ground, thereby realizing the movement of the frame body 1. A workpiece in-and-out conveying structure 3 is provided inside the workpiece loading gap 13, and a workpiece positioning component 4 is provided around the workpiece loading gap 13. The workpiece in-and-out conveying structure 3 is driven by a conveying drive mechanism 5 provided inside the frame body 1.

[0022] The frame body 1 is closed on both sides by sealing plates 14. The sealing plates 14 and the assembly positioning plates 12 form a circumferential wrap around the frame body 1, and the outer wall of the assembly positioning plates 12 is provided with several polyurethane buffers 15.

[0023] The sealing plate 14 is used for dust prevention and protection of both sides of the frame body 1, while the polyurethane buffer 15 is used to prevent damage caused by rigid collisions and provides flexible protection.

[0024] As can be seen, the workpiece in-and-out conveying structure 3 includes several workpiece support end plates 31 arranged in the workpiece loading gap 13 and located on the upper end face of the frame body 1, and a conveying roller group 32 is provided between two adjacent workpiece support end plates 31.

[0025] The workpiece support end plate 31 supports the workpiece, and the conveying rollers in the conveying roller group 32 are connected at one end by a synchronous belt to ensure synchronous conveying.

[0026] Furthermore, an auxiliary conveying support rod 33 is provided between the conveying roller assembly 32 and the workpiece support end plates 31 located on both sides, and auxiliary rollers 34 are provided at both ends of the auxiliary conveying support rod 33.

[0027] The auxiliary conveying support rod 33 improves the support strength and expands the support area, preventing material from sinking locally due to support gaps.

[0028] Furthermore, the conveying drive mechanism 5 includes a conveying drive motor 51 disposed within the frame body 1. The output end of the conveying drive motor 51 is connected to a linkage shaft 53 disposed on the frame body 1 via a linkage pulley 52. ​​Both ends of the linkage shaft 53 are connected to the end of one of the conveying rollers in the conveying roller assembly 32 via a linkage drive belt 54.

[0029] The conveyor drive motor 51 drives the linkage shaft 53 to rotate through the linkage pulley 52. ​​When the linkage shaft 53 rotates, it drives one of the conveyor rollers in the conveyor roller group 32 to rotate through the linkage drive belts 54 set at both ends. Since one end of the conveyor roller in the conveyor roller group 32 is connected by a synchronous belt, all the conveyor rollers in the conveyor roller group 32 rotate synchronously.

[0030] Specifically, the workpiece positioning assembly 4 includes a workpiece guide plate 41 disposed on the workpiece support end plate 31 at both ends of the workpiece loading gap 13 and in contact with the assembly positioning plate 12, and a blocking mechanism 42 is provided at both ends of the workpiece support end plate 31 located in the middle. The main function of the workpiece guide plate 41 is to guide the workpiece during loading and unloading, prevent misalignment, and allow for position adjustment to achieve clamping of both ends of the workpiece.

[0031] In detail, the blocking mechanism 42 includes a clearance through hole 421 provided on the workpiece support end plate 31. A blocking plate 423 is connected to the clearance through hole 421 through a rotating lifting seat 422. Rollers 424 are provided at both ends of the blocking plate 423. Auxiliary conveying rollers 425 are provided on both sides of the clearance through hole 421, and the auxiliary rollers 34 and the auxiliary conveying rollers 425 are located on the same axis.

[0032] The auxiliary rollers 34 and 425 ensure smooth feeding and unloading, prevent jamming, and increase loading and unloading speed.

[0033] More specifically, the bottom of the rotating lifting seat 422 is connected to a rotating drive link 427 via a linkage support rod 426. The two ends of the rotating drive link 427 are rotated and positioned via rotating connecting seats 428 set on the frame body 1. A pressing drive motor 429 is set inside the frame body 1. The pressing drive motor 429 is connected to the linkage wheel 4271 on the rotating drive link 427 via a linkage belt 4291.

[0034] The clamping drive motor 429 drives the rotating drive link 427 to rotate. When the rotating drive link 427 rotates, it drives the rotating lifting seat 422 and the blocking plate 423 to extend out of the clearance through hole 421 through the linkage support rod 426 and press the workpiece on both sides towards the inward direction.

[0035] Preferably, the drive guide mechanism 2 includes a rotary drive motor 21 disposed in the frame body 1, a linkage gear 22 disposed at the output end of the rotary drive motor 21, the linkage gear 22 being connected to the drive shaft 23 via a linkage chain, and the aforementioned drive wheel body 11 being disposed at both ends of the drive shaft 23. A horizontally disposed guide wheel 24 is disposed at the bottom of the frame body 1, the guide wheel 24 being in contact with the inner wall of the guide slide rail groove disposed on the ground, and the drive wheel body 11 being disposed in the guide slide rail groove.

[0036] The drive motor 21 drives the drive shaft 23 to rotate via the linkage chain, and the drive wheel 11 rotates synchronously, thereby driving the RGV shuttle to move in the guide rail groove. The guide wheel 24 contacts the inner wall of the guide rail groove to form a locking engagement, preventing derailment.

[0037] The output end of the drive motor 21 is connected to the linkage gear 22 via a bevel gear, and the drive shaft 23 is provided with a synchronous gear for connecting the linkage chain.

[0038] In addition, a laser rangefinder 16 is installed on the assembly positioning plate 12 at one end of the frame body 1, and an optical communication module 17 is installed on the assembly positioning plate 12 at the other end of the frame body 1.

[0039] The laser rangefinder 16 is used to detect position and distance, and the optical communication module 17 is used to set and control the movement position of the RGV shuttle to achieve precise loading and unloading position adjustment.

[0040] In summary, the principle of this embodiment is as follows: the auxiliary conveying support rod 33 between the conveying roller assembly 32 and the workpiece support end plates 31 on both sides enhances the support strength and expands the support area. The auxiliary rollers 34 at both ends cooperate with the conveying roller assembly 32 to form a rolling conveying surface, reducing the frictional resistance between the workpiece and the conveying structure, avoiding jamming, and improving the smoothness of conveying. The workpiece guide plate 41 guides the workpieces during loading and unloading, preventing misalignment, and its position can be adjusted to press the two ends of the workpiece. The pressing drive motor 429 drives the drive link 427 to rotate through the linkage belt 4291. The drive linkage 427 drives the rotating lifting seat 422 through the linkage support rod 426, so that the blocking plate 423 extends or retracts from the clearance through hole 421. When the workpiece is being transported, the retraction does not affect the passage. After the workpiece is in place, the extension contacts the workpiece through the rollers 424 at both ends, pressing the workpiece axially to restrict its movement, prevent slippage, and improve the stability of the workpiece during transportation. In addition, when the frame body 1 moves along the ground guide slide rail groove, the guide wheel 24 at the bottom of the frame body 1 contacts the inner wall of the slide rail groove to form a locking, restricting lateral deviation, avoiding derailment, and ensuring accurate movement trajectory.
