[0001] The present application relates to the technical field of conveying devices, in particular to a transport vehicle track divergence and confluence device for reducing vibration. BACKGROUND

[0002] In a high-precision manufacturing environment such as a semiconductor factory, an OHT (Overhead Hoist Transport) crane system as a key automatic conveying device undertakes the high-frequency transfer task of sensitive carriers such as chip wafers and process materials. In a conventional OHT track system, in order to realize the divergence and confluence of the logistics path, a large-angle intersection design is generally adopted, which causes the crane vehicle to need to perform a large-angle two-way turning operation during operation.

[0003] However, during the turning of the vehicle, due to the rigid vehicle body structure and the differential control ability of the multiple wheels, there is a significant speed difference and rolling track deviation between the driving wheels on both sides of the vehicle body. This speed change and wheel interference will cause the vehicle body attitude to be unstable, vibration to be intensified, and long-term operation will also cause non-uniform wear between the guide wheels and the track, thereby affecting the stability and quality assurance of the conveyed products. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a transport vehicle track divergence and confluence device for reducing vibration, which aims to at least partially alleviate the above-mentioned problems.

A turning guide strip is arranged at the turning track. The crane body is provided with a pair of left and right sliding guide assemblies comprising guide wheels, which slide to one side to contact the corresponding guide strip to complete the path turning when the vehicle drives to the turning track, and return to the initial position in the track segment after confluence. A transition track is arranged between the two sections of turning tracks, the transition track being arranged in the extension direction of the turning track and connected to the straight track b at the other end.

[0011] Preferably, one end of the sleeve rod extending into the sleeve is fixedly connected with a connecting plate, a plurality of communication openings are arranged in the connecting plate, a spring a is connected between the connecting plate and the sleeve, and a damping liquid is filled in the sleeve.

[0012] Preferably, a connecting frame is fixedly arranged in the driving table, a guide rod is connected with the connecting frame, two guide supports are slidably connected with the guide rod, a connecting opening is arranged in the guide rail, a pushing frame is connected with the bottom of the sliding block, the pushing frame extends into the driving table through the connecting opening and is located between the two guide supports, a guide rod is connected with the bottom of the guide support, a worm gear is connected with the connecting rod, a worm is rotatably connected with the connecting frame and engaged with the worm gear, a spiral opening is arranged in the worm, the guide rod is matched with the spiral opening, and a spring b is connected between the guide support and the connecting frame.

[0013] In summary, the present application mainly has the following beneficial effects: The application adopts a symmetric small-angle turning track matched with an integrated guide strip design, and a transversely-slidable guide assembly is arranged on the crown block body. The guide wheel is actively slid and adheres to the corresponding side guide strip before turning, so as to realize accurate guidance and lateral constraint of the vehicle in the path conversion process.

[0014] The application realizes automatic linkage response between the guide assembly action and the opposite magnetic attraction structure by arranging a magnetic attraction limiting part at the bottom of the driving table and cooperating with the guide sliding mechanism and the worm and gear linkage device. During the turning process, the guide wheel sliding triggers the opposite magnetic attraction limiting part to rotate and automatically dive, thereby enhancing the adhesion of the corresponding driving wheel through magnetic force and avoiding idling and slipping caused by the difference in turning radius. At the same time, the buffer mechanism of the spring and damping liquid is arranged inside the magnetic attraction part, which effectively absorbs the vibration impact when the guide wheel first contacts the guide strip, thereby improving the magnetic attraction stability and overall running stability. The structure responds quickly without the need for an additional control system, has self-adaptive, self-recovery and motion assistance capabilities, and significantly improves the running reliability of the crown block in the track split-flow turning section and the product carrying accuracy.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0018] Reference Figures 1-11 In the embodiment, a track divergence confluence device for reducing vibration includes a headstock body 100 and a track structure 101 cooperating with the headstock body 100.

[0019] The track structure 101 includes: two parallel straight tracks a 102 before confluence; two sections of turning tracks 103 respectively connected between the two parallel straight tracks a 102 and one straight track b 104 after confluence, and the two sections of turning tracks 103 are symmetrically arranged; one straight track b 104 after confluence, used for the headstock body 100 to continue running after completing path confluence; A transition track 107 is further arranged between the two sections of turning tracks 103, the extension direction of the transition track 107 is consistent with the direction of the foregoing turning track 103, and the transition track 107 is used for improving the running stability of the path switching process.

[0020] The turning track 103 is provided with a turning guide strip 105 for providing path constraint and lateral support to the overhead crane body 100 during the turning operation. In the embodiment, the guide strip 105 is an integral structure, which is consistent with the curvature of the turning track 103, and the length of the guide strip 105 matches the arc length of the corresponding turning track 103 to ensure the continuity and accuracy of the guide path.

[0021] The overhead crane body 100 is provided with a pair of guide assemblies which can slide in the left-right direction of the vehicle body, each guide assembly including a guide wheel 106, a lateral slide 202 and a cooperating guide rail 201 mechanism. In normal straight driving, the guide wheel 106 is in the middle position; when the overhead crane enters the turning track 103 section, the guide wheel 106 slides to one side and abuts against the corresponding guide strip 105, thereby completing the path guidance and lateral constraint. After completing the merging and entering the straight track b104 after merging, the guide wheel 106 automatically returns to the initial position.

[0022] Further, in order to reduce the vibration and noise generated by impact or friction during the guiding process, the wheel body surface of the guide wheel 106 is coated with a layer of elastic material, which can be polyurethane, rubber or thermoplastic elastomer, etc., having good cushioning and damping performance, effectively improving the stability and operation accuracy of the vehicle during the turning process.

[0023] Through the above arrangement, when the overhead crane body 100 normally drives along the parallel straight track a102, the guide wheel 106 in the guide assembly is in the middle position, at which time it does not contact any guide strip 105. As the vehicle travels to the divergence point of the track, the path enters the turning track 103 area. Since the track structure 101 is designed as a small-angle symmetric bifurcation, the overhead crane body 100 enters the turning track 103 according to the target path selection needs.

[0024] When the overhead crane body 100 enters the front section of the turning track 103, the guide assembly provided on the vehicle body starts to perform the sliding action, and the guide wheel 106 slides to the selected turning direction under the drive of the control mechanism, so that the guide wheel 106 abuts against the guide strip 105 on the corresponding side. Since the guide strip 105 is completely matched with the curvature of the turning track 103, and the inner side of the guide strip 105 is provided with an arc-shaped guide surface, the guide wheel 106 can smoothly enter the guide groove and realize smooth guiding along the guide strip 105.

[0025] During the whole turning process, the guide wheel 106 is in contact with and slides along the guide strip 105, thereby achieving lateral constraint and guidance for the overhead crane body 100, avoiding deviation or abnormal posture of the crane body due to turning. In order to prevent impact and vibration during the guiding process, the surface of the guide wheel 106 is provided with an elastic material coating structure, which has a certain buffering capacity when contacting the guide strip 105. After the overhead crane body 100 completes the first turning, it enters the transition track 107 arranged in the middle, and finally converges into the straight track b104 after merging, and the guide wheel 106 also slides back to the initial position in the middle, restoring the normal driving state.

[0026] In the embodiment, a set of sliding components for guiding is arranged on the overhead crane body 100, which includes a driving table 200, a guide rail 201, a sliding block 202 and a guide wheel 106. The driving table 200 is installed on the overhead crane body 100 through a bearing and can rotate during operation. The top of the driving table 200 is provided with a transverse guide rail 201, which is used to limit the movement of the sliding block 202 in the lateral direction of the overhead crane. The sliding block 202 is slidingly connected to the guide rail 201 and can reciprocate on the guide rail 201, thereby driving the guide wheel 106 to realize left and right sliding movement.

[0027] The guide wheel 106 is installed on the sliding block 202 through a bearing and can slide integrally with the sliding block 202, and has a rotational freedom degree when turning. This structure enables the guide wheel 106 to actively slide to one side in the turning track area, thereby being in contact with the integrated guide strip 105 arranged on the upper part of the turning track 103, and realizing path guidance.

[0028] In the embodiment, a driving shaft 203 is connected to the driving table 200 through a bearing, and the driving shaft 203 is arranged in the lateral direction of the driving table 200 and supported by the driving table 200. A set of driving wheels 204 is fixedly connected to both ends of the driving shaft 203, which is used to contact the track and drive the overhead crane body 100.

[0029] In order to realize active driving control, a servo motor a 205 is installed on the driving table 200, and the output shaft of the servo motor a 205 is connected to the driving shaft 203 through a chain mechanism 206.

[0030] Through the above arrangement, the traction required for the operation of the overhead crane body 100 is provided by the servo motor a 205 on the driving table 200. The output shaft of the servo motor is connected to the driving shaft 203 arranged in the lateral direction through the chain mechanism 206. When the servo motor is started, the output power is transmitted to the driving shaft 203 through the chain, and the driving shaft 203 rotates and drives the driving wheels 204 connected to both ends to rotate synchronously.

[0031] Since the driving shaft 203 is mounted on the driving table 200 through bearings, the frictional resistance is small during rotation, the operation is stable, and the transmission efficiency is high. The chain transmission mechanism has good mechanical matching performance and can accurately transmit the rotation speed and torque of the motor to the driving wheel 204, thereby ensuring the stable power response of the headstock body 100 in the acceleration, deceleration or low-speed uniform speed running state.

[0032] In the embodiment, in order to realize the lateral sliding function of the guide wheel 106 in the guide assembly of the headstock body 100, a sliding block 202 driving mechanism is arranged, which comprises a mounting seat 207, a servo motor b 208, an engagement plate 209 and a linkage engagement structure connected with the sliding block 202. Specifically: The mounting seat 207 is fixedly arranged on the side wall of the driving table 200 of the headstock body 100; A servo motor b 208 is arranged on the mounting seat 207, and the output end of the servo motor b 208 is connected with an engagement plate 209 through a flange; The engagement plate 209 is arranged horizontally below the bottom of the sliding block 202 and can rotate to form reciprocating swing; The lower part of the sliding block 202 is fixedly connected with a support plate 210, and the bottom surface of the support plate 210 is provided with a plurality of engagement columns 211 at equal intervals along the sliding direction; The lower end of the engagement column 211 can be engaged with the toothed structure on the engagement plate 209.

[0033] Through the above arrangement, during the working process, when the servo motor b 208 is started, the engagement plate 209 starts to rotate or eccentrically swing, the toothed area on the surface thereof is in point-by-point contact with the engagement column 211, the sliding block 202 is pushed to slide laterally along the guide rail 201 through continuous engagement action, so as to realize the lateral sliding of the guide wheel 106 from the middle position to the target side, and after completing the track turning and guiding, the motor reverses to make the guide wheel 106 return.

[0034] In the embodiment, in order to further improve the running stability of the vehicle during track turning or merging, prevent the vehicle body from yawing or driving from slipping due to uneven force on the inner and outer wheels during turning, a magnetic attraction limiting auxiliary structure is arranged at the bottom of the driving table 200. Specifically: A plurality of connecting openings 300 are formed in the bottom of the driving table 200, and the openings are downwardly arranged towards the running direction of the vehicle; Inside the driving platform 200, a set of rotatably arranged magnetic attraction limiting parts 301 are provided. When it is necessary to enhance the friction force of a certain side or limit the lateral drift of the vehicle, the magnetic attraction limiting parts 301 can be extended through the connecting opening 300 and contact the track structure 101 to achieve magnetic attraction. When attracted, additional vertical or lateral restraint force can be provided without increasing the mechanical contact burden, thereby improving the traction of the vehicle at the turning point or inhibiting the change in attitude. After completing the turning path, the magnetic attraction limiting parts 301 can be rotated to reset to the inside of the driving platform 200.

[0035] In this embodiment, in order to improve the adhesion between the crown block and the track during track turning, merging, and other track turning processes, and to inhibit the problem of slipping or insufficient friction of the driving wheel 204 on one side due to load changes, a set of telescopic magnetic attraction limiting mechanisms are provided inside the driving platform 200 for magnetic auxiliary attraction and limiting control when needed. Specifically: The magnetic attraction limiting part 301 includes a connecting rod 302 rotatably arranged inside the driving platform 200; A sleeve 303 is fixed on the connecting rod 302, which can be rotated to the connecting opening 300 position at the bottom of the driving platform 200 under the driving of the connecting rod 302; A sleeve rod 304 is slidably connected inside the sleeve 303, which can extend axially along the sleeve 303; A magnetic member 305, such as a rare earth permanent magnet or an electromagnet assembly, is embedded inside the sleeve rod 304, which faces the track direction and can achieve magnetic attraction when approaching the track; A plurality of balls 306 are provided at the end of the sleeve rod 304, i.e. the end contacting the track structure 101, which are rotatably connected and can provide rolling support when the sleeve rod 304 is pressed or attracted to the track surface, preventing wear and reducing resistance.

[0036] Through the above arrangement, when the vehicle enters the turning track 103 area, the connecting rod 302 performs a rotating action, the magnetic member 305 approaches the track through the sleeve rod 304, and the downward pressure on that side is enhanced through the magnetic attraction force, thereby improving the friction or adhesion of the driving wheel 204 on that side, avoiding problems such as slipping, instability, and increased vibration during turning due to load transfer.

[0037] After turning is completed, the sleeve rod 304 can be retracted into the sleeve 303, and the connecting rod 302 is rotated to reset to the inside of the driving platform 200, and the magnetic attraction limiting part 301 is immediately separated from the track, returning to the normal state, ensuring that it does not interfere with the track and other structures during operation.

[0038] In addition, the magnetic part 305 generates a downward attractive force in the process of attracting the track metal material, thereby driving the sleeve rod 304 to slide downward under the joint action of gravity and magnetic force, so that the magnetic part 305 approaches or contacts the track surface, realizing the automatic extension and adsorption process without external thrust.

[0039] Since the inside and bottom space of the driving table 200 are limited, the magnetic attraction limiting part 301 needs to be accommodated in the driving table 200 in the inaction state, so as to avoid interference with the track to cause the moving resistance of the crown body 100 when moving in a straight line. Therefore, the sleeve 303 and the sleeve rod 304 structure are designed to be telescopic, so that the magnetic attraction limiting part 301 can be kept compact in the non-working state and automatically release the stroke in the working state, effectively balancing the compactness of the structure and the functional release demand. Through the rolling contact between the ball 306 and the track, not only the magnetic part 305 is avoided to directly contact the track surface to cause the jamming, but also the crown body 100 is allowed to continue to move along the track direction while maintaining the adsorption force, effectively preventing the magnetic attraction force from causing the blockage or drag burden to the operation, realizing the balance between the adhesion force enhancement and the movement freedom.

[0040] In the embodiment, in order to further improve the dynamic response stability of the crown in the turning path and prevent the structural vibration caused by the contact between the guide wheel 106 and the guide bar 105, a damping mechanism is further provided. Specifically: One end of the sleeve rod 304 extending into the sleeve 303 is fixedly connected with a connecting plate 307, and a plurality of communication openings 308 are uniformly arranged on the connecting plate 307; The connecting plate 307 is connected with the sleeve 303 through a spring a 309, which is used to provide a return or buffer force; The inside of the sleeve 303 is filled with damping liquid, preferably hydraulic oil or silicone oil with moderate viscosity.

[0041] Through the above setting, before the crown body 100 enters the turning section of the track structure 101, the guide wheel 106 on the vehicle body first slides transversely to the target side under the action of the servo motor b 208, and is ready to cooperate with the guide bar 105 on the turning track 103. Then, the connecting rod 302 on the corresponding side drives the sleeve 303 to rotate and overturn, and the attractive force between the magnetic attraction part and the track structure 101 is generated.

[0042] At this time, the magnetic part 305 generates downward suction force, and under the action of gravity and magnetic force, the sleeve rod 304 slowly slides downward in the sleeve 303. Since the sleeve 303 is filled with damping liquid, and a plurality of communication openings 308 are arranged on the connecting plate 307 at the tail of the sleeve rod 304, when the sleeve rod 304 slides, the liquid is forced to flow through the communication openings 308, generating viscous resistance, thereby forming damping buffering effect. Finally, the magnetic part 305 slowly slides downward under the action of magnetic force, driving the sleeve rod 304 to complete flexible contact of the ball 306 with the track.

[0043] During the travel of the head sheave on the turning track, the first contact between the guide wheel 106 and the guide strip 105 will inevitably generate a certain impact or vibration transmission, which will be conducted to the magnetic suction limiting part 301 through the vehicle body structure. When the head sheave body 100 is subjected to vibration, the magnetic part 305 tries to generate adhesion relative to the track, but due to the dynamic disturbance of the vehicle body at this time, it may cause the magnetic suction part to shake or unstable downward pressing. The role of the spring a 309 is to form flexible constraint, and the damping liquid flows through the communication openings 308 on the connecting plate 307 at the tail of the sleeve rod 304 to provide viscous resistance, thereby forming buffering damping when the magnetic part 305 tries to quickly press downward or shakes due to vibration.

[0044] The above mechanism can effectively absorb the vibration impact of the head sheave body 100 at the moment when the guide wheel 106 contacts the guide strip 105, preventing the disturbance from causing structural impact or affecting the adhesion stability of the magnetic suction limiting part 301.

[0045] In the present embodiment, in order to realize automatic magnetic suction cooperation of the corresponding pair of magnetic suction limiting parts 301 with the track structure 101 after the sliding of the guide wheel 106, a synchronous response structure is arranged in the driving table 200. Specifically: The connecting frame 400 is fixedly installed in the driving table 200; The connecting frame 400 is provided with a horizontally arranged guide rod 401, and the guide rod 401 is slidably connected with two guide supports 402; The bottom of the guide rail 201 is provided with a connecting opening 403, and a pushing frame 404 is connected below the sliding block 202, the pushing frame 404 extends into the driving table 200 through the connecting opening 403 and is arranged between the two guide supports 402; The bottom of each guide support 402 is provided with a guide rod 405, and the guide rod 405 is inserted downward into the spiral opening 408; The connecting rod 302 is fixedly provided with a worm gear 406, the connecting frame 400 is rotatably provided with a worm shaft 407 matched with the worm gear 406, and the spiral opening 408 is arranged on the worm shaft 407.

[0046] Through the above setting, during the operation of the crown block body 100 along the straight track, the slider 202 is in the middle position with the guide wheel 106, at this time the push frame 404 is located between the two guide supports 402, the magnetic attraction structure keeps the initial position and does not interfere with the operation of the vehicle. When the crown block enters the branch 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 the bottom push frame 404 also moves, contacting and pushing the guide support 402 on the side to produce axial displacement.

[0047] During the sliding of the guide support 402, the guide rod 405 connected at the bottom also slides forward synchronously, and generates an axial thrust through cooperation with the spiral port 408 on the worm 407, thereby driving the worm 407 to rotate. The rotation of the worm 407 drives the worm gear 406 engaged therewith to rotate, and the worm gear 406 drives the connecting rod 302 to rotate, so that the magnetic attraction assembly (including the sleeve 303 and the sleeve rod 304) on the opposite side of the turning completes angular rotation, and the magnetic surface faces the track structure 101.

[0048] At this time, due to the magnetic attraction force, the sleeve rod 304 slides downward under the dual action of gravity and magnetic force, so that the magnetic part 305 gradually approaches or contacts the track surface, realizes the enhancement of the magnetic attraction, and further enhances the friction force between the driving wheel 204 on the side and the track, prevents the driving wheel 204 from idling or slipping due to the difference in turning radius between the inside and outside of the vehicle.

[0049] The linkage structure utilizes the structural action caused by the sliding behavior of the guide wheel 106 to realize automatic adjustment of the magnetic attraction force on the opposite side, and the linkage mechanism triggered automatically by the posture change of the crown block has the advantages of simple structure and timely response, and can automatically enhance the adhesion of the driving wheel 204 on the opposite side during the turning of the vehicle, effectively avoiding wheel slip and posture drift.

[0050] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
