Description

Technical Field

[0001] This invention relates to the field of handling equipment technology, and more specifically to a transect and merging device for transport vehicle tracks to reduce vibration. Background Technology

[0002] In high-precision manufacturing environments such as semiconductor factories, OHT (Overhead Hoist Transport) systems serve as critical automated handling equipment, undertaking high-frequency transport tasks for sensitive carriers such as chip wafers and process materials. In conventional OHT track systems, large-angle intersection designs are commonly used to achieve the divergence and merging of material paths, which requires the crane vehicles to perform large-angle bidirectional turning operations during operation.

[0003] However, during vehicle turning, due to the rigid body structure and multi-wheel differential control capability, there is a significant difference in rotational speed and rolling trajectory deviation between the drive wheels on both sides of the vehicle. This speed change and wheel interference can cause problems such as unstable vehicle posture and increased vibration. Long-term operation can also cause uneven wear between the guide wheels and the track, thereby affecting the stability and quality assurance of the transported products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vehicle track branching and merging device for reducing vibration, aiming to alleviate the aforementioned problems to at least some extent.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A turning guide bar is provided at the turning track;

[0008] The crane body is equipped with a pair of guide components that can slide left and right, including guide wheels. When the vehicle travels to the turning track, the guide wheels slide to one side and contact the corresponding guide bar to complete the path turning, and return to the initial position after merging.

[0009] A transition track is provided between the two turning tracks. The transition track is located in the extension direction of the turning track, and its other end is connected to the straight track b.

[0011] Preferably, a drive shaft is connected to the drive platform via bearings, and drive wheels are connected to the two ends of the drive shaft. A servo motor a is connected to the drive platform, and its drive shaft is connected to the drive shaft via a chain mechanism.

[0012] Preferably, the drive platform is connected to a mounting base, on which a servo motor b is mounted. A meshing plate is connected to the output shaft of the servo motor b. A support plate is fixed on the slider, corresponding to the position of the meshing plate. A plurality of meshing pins adapted to the meshing plate are connected to the support plate.

[0013] Preferably, the bottom of the drive platform is provided with a connection opening, and a set of magnetic limiting parts are provided inside the drive platform. The magnetic limiting parts can rotate inside the drive platform and contact the track structure through the connection opening.

[0014] Preferably, the magnetic limiting part includes a connecting rod rotatably connected to the drive platform, a sleeve fixedly connected to the connecting rod, a sleeve rod slidably connected inside the sleeve, a magnetic element inside the sleeve rod, and a plurality of ball bearings rotatably connected to the end of the sleeve rod that contacts the track structure.

[0015] Preferably, a connecting plate is fixed to one end of the sleeve extending into the sleeve, the connecting plate has multiple communication ports, a spring a is connected between the connecting plate and the sleeve, and the sleeve is filled with damping fluid.

[0016] Preferably, a connecting frame is fixed inside the drive platform, a guide rod is connected to the connecting frame, two guide brackets are slidably connected to the guide rod, a connection port is opened on the guide rail, a push frame is connected to the bottom of the slider, the push frame extends through the connection port into the drive platform and is located between the two guide brackets, a guide rod is connected to the bottom of the guide bracket, a worm gear is connected to the connecting rod, a worm that meshes with the worm gear is rotatably connected to the connecting frame, a helical opening is opened on the worm, the guide rod cooperates with the helical opening, and a spring b is connected between the guide bracket and the connecting frame.

[0017] In summary, the present invention has the following main beneficial effects:

[0018] This invention employs a symmetrical, small-angle turning track design combined with an integrated guide bar, and incorporates laterally sliding guide components on the crane body. By actively sliding and engaging with the corresponding side guide bar before turning, precise guidance and lateral constraint are achieved during path transitions. Due to the reduced turning angle, the vehicle requires minimal attitude adjustments during bidirectional turns, significantly reducing the speed difference between the drive wheels and preventing instantaneous impacts. The guide wheel surface is covered with an elastic coating that absorbs the impact force from minute displacements between the guide rails, effectively mitigating vibrations caused by structural deformation. Simultaneously, the small-angle turning path reduces the traction difference between wheel sets, decreasing lateral stress on the crane axle and traveling components, reducing wear, extending service life, and overall improving operational stability and structural durability.

[0019] This invention achieves automatic linkage response between the guide component's movement and the opposite magnetic attraction structure by setting a magnetic attraction limiting part at the bottom of the drive platform, in conjunction with a guide sliding mechanism and a worm gear linkage device. During turning, the guide wheel slides, triggering the opposite magnetic attraction limiting part to rotate, flip, and automatically lower itself. The magnetic force enhances the adhesion of the corresponding drive wheel, preventing slippage and spinning caused by differences in turning radius. Simultaneously, a buffer mechanism with springs and damping fluid inside the magnetic attraction part effectively absorbs vibration and impact when the guide wheel first contacts the guide bar, improving magnetic stability and overall operational smoothness. This structure offers rapid response, requires no additional control system, and possesses adaptive, self-recovering, and motion-assisted capabilities, significantly improving the reliability of the overhead crane's operation and the accuracy of product handling in track merging and diverging turning sections.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] refer to Figures 1-11 In this embodiment, a transport vehicle track branching and merging device for reducing vibration includes: a crane body 100, and a track structure 101 that operates in cooperation with the crane body 100.

[0039] The track structure 101 includes:

[0040] Two parallel straight tracks a102 before the confluence;

[0041] Two turning tracks 103 are respectively connected between two parallel straight tracks a102 and a merging track, and the two turning tracks 103 are arranged symmetrically.

[0042] A straight track b104 after merging is used for the crane body 100 to continue running after completing the path merging;

[0043] A transition track 107 is also provided between the two turning tracks 103. The extension direction of the transition track 107 is consistent with the direction of the aforementioned turning track 103, which is used to improve the operational stability of the path switching process.

[0044] A turning guide bar 105 is provided at the turning track 103 to provide path constraint and lateral support for the crane body 100 during vehicle turning. In this embodiment, the guide bar 105 is an integral structure that maintains the same curvature as the turning track 103, and its length matches the arc length of the corresponding turning track 103 to ensure the continuity of the guiding path and the guiding accuracy.

[0045] The overhead crane body 100 is equipped with a pair of guide components that can slide along the left and right directions of the crane body. Each guide component includes a guide wheel 106, a transverse slider 202, and a cooperating guide rail 201 mechanism. During normal straight-line travel, the guide wheel 106 is in the middle position; when the crane enters the turning track 103, the guide wheel 106 slides to one side and abuts against the corresponding guide bar 105, thereby completing path guidance and lateral constraint. After completing the merging and entering the merging straight track b104, the guide wheel 106 automatically returns to its initial position.

[0046] Furthermore, to reduce vibration and noise caused by impact or friction during the guiding process, the surface of the guide wheel 106 is covered with an elastic material layer, which can be polyurethane, rubber or thermoplastic elastomer, etc., and has good buffering and vibration reduction performance, effectively improving the stability and running accuracy of the vehicle during the steering process.

[0047] With the above setup, when the crane body 100 travels normally along the parallel straight track a102, the guide wheel 106 in the guide assembly is in the middle position and does not contact any guide bar 105. As the vehicle travels to the bifurcation point of the track, the path enters the turning track 103 area. Since the track structure 101 is designed with a small-angle symmetrical bifurcation, the crane body 100 selects the turning track 103 to enter according to the target path.

[0048] When the vehicle body 100 enters the front section of the turning track 103, the guide assembly on the vehicle body begins to slide. Under the drive of the control mechanism, the guide wheel 106 slides in the selected turning direction, so that the guide wheel 106 abuts against the guide bar 105 on the corresponding side. Since the curvature of the guide bar 105 is perfectly matched with that of the turning track 103, and the inner side of the guide bar 105 is provided with an arc-shaped guide surface, the guide wheel 106 can smoothly enter the guide groove and be smoothly guided along the guide bar 105.

[0049] Throughout the turning process, the guide wheel 106 continuously contacts and slides against the guide bar 105, thereby providing lateral constraint and guidance for the crane body 100 and preventing the vehicle from deviating or exhibiting abnormal posture due to turning. To prevent impact and vibration during the guiding process, the surface of the guide wheel 106 is covered with an elastic material, providing a certain degree of cushioning when in contact with the guide bar 105. After completing the first stage of turning, the crane body 100 enters the transition track 107 located in the middle and finally merges into the straight track b104 after confluence. The guide wheel 106 then slides back to its initial middle position, resuming normal driving.

[0050] In this embodiment, the overhead crane body 100 is provided with a set of guiding sliding components, which include a drive platform 200, a guide rail 201, a slider 202, and a guide wheel 106. The drive platform 200 is mounted on the overhead crane body 100 via bearings and can rotate during operation. A transverse guide rail 201 is provided on the top of the drive platform 200, which limits the movement of the slider 202 along the transverse direction of the overhead crane. The slider 202 is slidably connected to the guide rail 201 and can reciprocate on the guide rail 201, thereby driving the guide wheel 106 to perform left and right sliding movements.

[0051] The guide wheel 106 is mounted on the slider 202 via bearings, allowing it to slide as a whole with the slider 202 and maintain its own rotational freedom during turns. This structure enables the guide wheel 106 to actively slide to one side as needed within the track turning area, thereby making contact with the integrated guide strip 105 located on the upper part of the turning track 103 to achieve path guidance.

[0052] In this embodiment, a drive shaft 203 is connected to the drive platform 200 via bearings. The shaft is arranged along the transverse direction of the drive platform 200, with the drive platform 200 as a supporting member. A set of drive wheels 204 are fixedly connected to both ends of the drive shaft 203, which are used to contact the track and drive the crane body 100.

[0053] To achieve active drive control, a servo motor a205 is installed on the drive platform 200, and its output shaft is connected to the drive shaft 203 through a chain mechanism 206 via a sprocket.

[0054] With the above configuration, the traction force required for the operation of the overhead crane body 100 is provided by the servo motor a205 on the drive platform 200. The output shaft of the servo motor is connected to the horizontally arranged drive shaft 203 via a chain mechanism 206. When the servo motor starts, its output power is transmitted to the drive shaft 203 via the chain, and the drive shaft 203 then rotates, causing the drive wheels 204 connected to its two ends to rotate synchronously.

[0055] Because the drive shaft 203 is mounted on the drive platform 200 via bearings, it experiences low frictional resistance during rotation, resulting in smooth operation and high transmission efficiency. The chain drive mechanism has excellent mechanical matching performance, enabling it to accurately transmit the motor's speed and torque to the drive wheel 204, thereby ensuring stable power response of the crane body 100 during acceleration, deceleration, or low-speed constant-speed operation.

[0056] In this embodiment, to achieve the lateral sliding function of the guide wheel 106 in the guide assembly on the crane body 100, a slider 202 driving mechanism is provided. This mechanism includes: a mounting base 207, a servo motor b208, a meshing plate 209, and a linkage meshing structure connected to the slider 202. Specifically:

[0057] The mounting base 207 is fixedly installed on the side wall of the drive platform 200 of the crane body 100;

[0058] A servo motor b208 is mounted on the mounting base 207, and its output end is connected to a meshing plate 209 via a flange.

[0059] The meshing plate 209 is arranged horizontally and located below the bottom of the slider 202, and can rotate with the motor conveying shaft to form a reciprocating swing.

[0060] A support plate 210 is fixedly connected to the lower part of the slider 202. Multiple meshing pins 211 are evenly spaced on the bottom surface of the support plate 210 along the sliding direction.

[0061] The lower end of the meshing post 211 can engage with the toothed structure on the meshing plate 209.

[0062] With the above settings, during operation, when the servo motor b208 starts, the meshing plate 209 begins to rotate or make an eccentric swing motion. Its surface toothed area contacts and engages with the meshing column 211 point by point. Through continuous meshing action, the slider 202 is pushed to slide laterally along the guide rail 201, thereby realizing the guide wheel 106 sliding from the middle position to the target side. After completing the track turning guidance, the motor reverses its action to return the guide wheel 106 to its original position.

[0063] In this embodiment, to further improve the vehicle's operational stability during track turning or merging, and to prevent vehicle body swaying or drive slippage due to uneven force on the inner and outer wheels during turning, a magnetic limiting auxiliary structure is provided at the bottom of the drive platform 200. Specifically:

[0064] The bottom of the drive platform 200 has multiple connection openings 300, which face downwards in the direction of vehicle travel.

[0065] Inside the drive platform 200, there is a set of rotatably arranged magnetic retaining parts 301. When it is necessary to enhance the friction on one side or limit the lateral drift of the vehicle, the magnetic retaining parts 301 can extend through the connection opening 300 and contact the track structure 101 to achieve magnetic adsorption. During adsorption, additional vertical or lateral constraint forces can be provided without increasing the mechanical contact burden, thereby improving the traction of the vehicle at the turning point or suppressing attitude changes. After completing the turning path, the magnetic retaining parts 301 can be rotated back into the drive platform 200.

[0066] In this embodiment, to improve the adhesion between the overhead crane and the track during track changes such as turning and merging, and to suppress slippage or insufficient friction of one drive wheel 204 due to load changes, a set of retractable magnetic attraction limiting mechanisms is installed inside the drive platform 200 to achieve magnetic-assisted attraction and limiting control when needed. Specifically:

[0067] The magnetic attraction limiting part 301 includes a connecting rod 302, which is rotatably disposed inside the drive stage 200.

[0068] A sleeve 303 is fixed on the connecting rod 302. The sleeve 303 can be rotated and flipped out to the connection opening 300 position at the bottom of the drive table 200 under the drive of the connecting rod 302.

[0069] A sleeve rod 304 is slidably connected inside the sleeve 303, and the sleeve rod 304 can extend out along the axial direction of the sleeve 303;

[0070] A magnetic component 305, such as a rare earth permanent magnet or an electromagnet assembly, is embedded inside the sleeve rod 304. The magnetic component 305 faces the track direction and can achieve magnetic adsorption when it is close to the track.

[0071] The end of the sleeve 304, that is, the end that contacts the track structure 101, is provided with a plurality of balls 306, which are connected in a rotatable manner. These balls provide rolling support when the sleeve 304 is pressed down or adsorbed into contact with the track surface, preventing wear and reducing resistance.

[0072] With the above setup, when the vehicle enters the turning track 103 area, the connecting rod 302 rotates, and the magnetic component 305 approaches the track via the sleeve rod 304. The magnetic attraction force enhances the downward pressure on that side, thereby increasing the friction or adhesion of the drive wheel 204 on that side, and preventing the vehicle from slipping, becoming unstable, or experiencing increased vibration due to load transfer during the turning process.

[0073] After the turn is completed, the sleeve 304 can retract into the sleeve 303 and be rotated back to the drive platform 200 by the connecting rod 302. The magnetic limit part 301 then disengages from the track and returns to the normal state, ensuring that it does not interfere with the track and other structures during operation.

[0074] In addition, the magnetic component 305 generates a downward attractive force during the process of attracting the track metal material, which in turn drives the sleeve rod 304 to slide downward under the combined action of gravity and magnetic force, so that the magnetic component 305 approaches or contacts the track surface, realizing the automatic extension and adsorption process without external thrust.

[0075] Due to the limited internal and bottom space of the drive platform 200, the magnetic limiting part 301 needs to be stored inside the drive platform 200 when not in operation to avoid interference with the track and causing movement resistance to the crane body 100 when traveling in a straight line. Therefore, it is designed as a telescopic sleeve 303 and a sleeve rod 304 structure, so that the magnetic limiting part 301 can remain compact when not in operation and automatically release its stroke when in operation, effectively balancing structural compactness and functional release requirements. Through the rolling contact between the ball bearing 306 and the track, not only is direct hard contact between the magnetic component 305 and the track surface avoided, which would cause jamming, but the crane body 100 can also continue to move along the track direction while maintaining the attraction force, effectively preventing the magnetic attraction force from causing obstruction or dragging burden on the operation, and achieving a balance between enhanced adhesion and freedom of movement.

[0076] In this embodiment, to further improve the dynamic response stability of the overhead crane in the turning path and prevent structural vibration caused by the contact between the guide wheel 106 and the guide bar 105, a damping mechanism is further provided. Specifically:

[0077] One end of the sleeve rod 304 extending into the sleeve 303 is fixedly connected to a connecting plate 307, and the connecting plate 307 is provided with a plurality of evenly arranged communication ports 308.

[0078] A spring a309 is connected between the connecting plate 307 and the sleeve 303 to provide return or buffering force.

[0079] The sleeve 303 is filled with a damping fluid, preferably hydraulic oil or silicone oil of suitable viscosity.

[0080] With the above setup, during actual operation, before the crane body 100 enters the turning section of the track structure 101, the guide wheel 106 on the crane body first slides laterally to the target side under the action of the servo motor b208, and prepares to cooperate with the guide bar 105 on the turning track 103. Subsequently, the corresponding connecting rod 302 on the opposite side drives the sleeve 303 to rotate and flip, generating an attraction between the magnetic attraction component and the track structure 101.

[0081] At this point, the magnetic component 305 generates a downward attractive force, and simultaneously, under the combined action of gravity and magnetism, the sleeve 304 slowly slides downward within the sleeve 303. Since the sleeve 303 is filled with damping fluid, and the connecting plate 307 at the tail of the sleeve 304 has multiple connecting ports 308, as the sleeve 304 slides, the fluid is forced to flow through these ports 308, generating viscous resistance and thus creating a damping buffer effect. Finally, under the action of magnetism, the magnetic component 305 drives the sleeve 304 to slowly slide downward, completing the flexible contact between the ball bearing 306 and the track.

[0082] During the crane's movement on the turning track, the initial contact between the guide wheel 106 and the guide bar 105 will inevitably generate a certain impact or vibration transmission. This vibration will be transmitted step by step through the car body structure to the magnetic attraction limiting part 301. When the crane body 100 is subjected to vibration, the magnetic component 305 attempts to adhere to the track, but due to the dynamic disturbance of the car body at this time, it may cause the magnetic component to sway or unstable downward pressure. The function of the spring a309 is to form a flexible constraint. The damping fluid flows through the connecting port 308 on the connecting plate 307 at the tail of the sleeve rod 304, providing viscous resistance, forming buffer damping when the magnetic component 305 attempts to press down quickly or sways due to vibration.

[0083] In summary, the above mechanism can effectively absorb the vibration and impact of the crane body 100 at the moment when the guide wheel 106 contacts the guide bar 105, preventing the disturbance from causing structural impact on the magnetic attraction limiting part 301 or affecting the adsorption stability.

[0084] In this embodiment, to ensure that the magnetically limiting part 301 on the corresponding side automatically magnetically engages with the track structure 101 after the guide wheel 106 slides, a synchronous response structure is provided inside the drive platform 200. Specifically:

[0085] A connecting frame 400 is fixedly installed inside the drive platform 200;

[0086] The connecting frame 400 is provided with a horizontally arranged guide rod 401, and two guide brackets 402 are slidably connected to the guide rod 401;

[0087] The bottom of the guide rail 201 has a connection port 403. A pusher 404 is connected below the slider 202. The pusher 404 extends through the connection port 403 into the drive table 200 and is arranged between the two guide supports 402.

[0088] Each guide bracket 402 has a guide rod 405 at its bottom, and the guide rod 405 is inserted downward into the spiral opening 408;

[0089] A worm gear 406 is fixed on the connecting rod 302, and a worm 407 that cooperates with the worm gear 406 is rotatably mounted on the connecting frame 400, with a helical opening 408 formed on the worm 407.

[0090] With the above setup, during the operation of the overhead crane body 100 along the straight track, the slider 202 and the guide wheel 106 are in the middle position. At this time, the pusher frame 404 is located between the two guide supports 402, and the magnetic attraction structure maintains its initial position without interfering with the operation of the vehicle. When the overhead crane enters the bifurcation section and needs to run along the turning track 103, the slider 202 where the guide wheel 106 is located slides to one side, and at the same time, its bottom pusher frame 404 also moves accordingly, contacting and pushing the guide support 402 on that side to cause axial displacement.

[0091] During the sliding process, the guide rod 405 connected to its bottom also slides forward synchronously, and generates axial thrust by cooperating with the helical opening 408 on the worm 407, thereby driving the worm 407 to rotate. The rotation of the worm 407 will drive the worm wheel 406 meshing with it to rotate, and the worm wheel 406 will drive the connecting rod 302 to rotate, so that the magnetic attraction assembly (including the sleeve 303 and the sleeve rod 304) located on the opposite side of the steering completes the angular rotation, and the magnetic surface faces the track structure 101.

[0092] At this time, due to the magnetic attraction, the sleeve 304 slides downward under the combined action of gravity and magnetic force, causing the magnetic component 305 to gradually approach or contact the track surface, thereby enhancing the magnetic attraction and increasing the friction between the drive wheel 204 on this side and the track, preventing the drive wheel 204 from spinning or slipping due to the difference in turning radius between the inner and outer sides of the vehicle.

[0093] This linkage structure utilizes the structural action caused by the slippage behavior of the guide wheel 106 to achieve automatic adjustment of the magnetic attraction applied to the opposite side. The linkage mechanism, which is automatically triggered by changes in the crane's attitude, has the advantages of simple structure and timely response. It can automatically enhance the adhesion of the opposite drive wheel 204 during vehicle turning, effectively avoiding wheel slippage and attitude drift.

[0094] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
