Description

Technical Field

[0001] The present invention relates to the technical field of blade grid structure forming, and in particular to a high-fault-tolerance linear motor drive assembly device and a fault-tolerance method. Background Art

[0002] In the airport baggage handling system, driving devices are required in the equipment related to transportation and sorting. At present, general conveying equipment uses rotary motors to provide conveying power. However, in baggage sorting equipment, the conveying power is mainly provided by linear motors. The general rotary motor converts the rotary motion into the linear motion of the moving parts, while the linear motor can achieve linear motion without intermediate conversion. Generally, the baggage sorting conveyor line is a circular conveyor line with strong continuity. If a rotary motor is used to provide power for it, the structure of the intermediate conversion device that converts the rotary motion into the linear motion will be more complicated. In contrast, if a linear motor is used to provide power for it, there is no need for an intermediate conversion device, the structure is relatively simple, and it can respond quickly and has good follow-up performance.

[0003] At present, there are two common linear motor drive methods, such as Figure 1 As shown, the driving mode 1 is the linear motor magnetic pole flat type, and the slide is driven to perform linear motion as the magnetic pole changes; Figure 2 As shown, the second driving mode is that the metal plate is driven by induction in the magnetic field formed by the magnetic pole pair of the linear motor. When using a linear motor, in the case of driving mode one, the gap between the linear motor and the slide is particularly important, which determines the size of the driving force. Therefore, the installation requirements of the linear motor are relatively high, that is, the distance between the linear motor and the slide needs to be guaranteed to be a certain distance, and the distance should not be too large. Due to this installation requirement, after the pallet carries goods many times, its slide may be too close to the linear motor due to deformation of the mounting frame or wear of the guide wheel, or tilted, and the loop conveying speed is fast. The above situation is very likely to cause the linear motor and the slide to collide in motion, causing damage to the equipment. Similarly, in the case of driving mode two, the distance between the magnetic poles N (S) and S (N) of the linear motor is also relatively narrow. The metal plate moving in the magnetic field will collide with the linear motor due to the tilt of the slide, causing damage.

[0004] Chinese patent (CN109277309A) discloses an anti-collision device and a cross-belt sorting system, and Chinese patent (CN108355978B) discloses a linear motor anti-collision device and a cross-belt sorting machine. The above-mentioned prior art only uses the change of the motion state of the mechanical structure to determine whether the linear motor will be hit. The detection method is single and the fault tolerance rate is low. This method lacks protection against sudden situations. If the slide table rises and falls or tilts too much instantly, even if it is detected that the corresponding linear motor will be hit, it cannot avoid damage to the linear motor.

[0005] Therefore, how to provide a high fault tolerance linear motor drive assembly device and fault tolerance method with multiple protection structures, high fault tolerance, and the ability to avoid collision between the slide and the linear motor is an urgent problem that needs to be solved by technical personnel in this field. Summary of the invention

[0006] In view of this, the present invention proposes a high-tolerance linear motor drive combination device and a fault-tolerant method, aiming to solve the technical problem that the traditional linear motor anti-collision device has a low fault tolerance and cannot effectively avoid collision between the slide and the linear motor.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] On one hand, the present invention provides a high-tolerance linear motor drive assembly device, wherein the linear motor is connected to a slide table to drive the slide table to move and transport above the linear motor; the assembly device comprises:

[0009] A frame, wherein the frame is arranged below the linear motor;

[0010] An anti-collision guide lifting assembly, the anti-collision guide lifting assembly is installed on the frame and arranged corresponding to the starting end of the conveying direction of the linear motor; a guide plate structure is provided on the top of the anti-collision guide lifting assembly, and the guide plate structure is configured to slide against and guide and lift the slide to the top of the corresponding linear motor when the operating height of the slide is lower than its preset height;

[0011] An over-proximity detection mechanism, the over-proximity detection mechanism is mounted on the frame; the trigger end of the over-proximity detection mechanism is arranged corresponding to the upper side of the guide plate structure; when the slide slides over the upper surface of the guide plate structure, it can abut against the trigger end, so that the over-proximity detection mechanism sends an emergency stop signal;

[0012] A lifting and lowering adjustment mechanism, wherein the lifting and lowering adjustment mechanism is mounted on the frame and is located below the linear motor, and a lifting end of the lifting and lowering adjustment mechanism is transmission-connected to the linear motor to perform lifting and lowering adjustment on the linear motor;

[0013] A controller is provided, wherein the controller is electrically connected to the over-proximity detection mechanism and the lifting and adjusting mechanism, so as to control the linear motor to descend and avoid the slide table through the lifting and adjusting mechanism when an emergency stop signal is received from the over-proximity detection mechanism.

[0014] When the high-tolerance linear motor drive combination device of the present invention is in use, the trigger end of the proximity detection mechanism is higher than the guide plate structure, and can preferentially touch the trigger end when the slide operation height gradually decreases and approaches the preset height, so that the proximity detection mechanism sends an emergency stop signal, and then the controller controls the linear motor to stop and stop driving the slide; when the height of the running slide changes greatly, the running height is lower than the preset height and preferentially touches the guide plate structure, the guide plate structure of the anti-collision guide lifting assembly can guide the slide to move and lift the slide height to avoid the slide from colliding with the linear motor; and the slide will inevitably touch the trigger end when sliding along the upper surface of the guide plate structure to stop, so as to prevent the slide from crossing the guide plate structure and hitting the linear motor; after receiving the emergency stop signal sent by the proximity detection mechanism, the controller can control the linear motor to urgently descend through the lifting and adjusting mechanism to avoid the slide, so as to prevent the slide from inertia overshooting to the top of the linear motor and pressing on the linear motor.

[0015] As a further improvement of the above technical solution, the anti-collision guide lifting assembly includes a detection plate mounting bracket arranged corresponding to the starting end of the conveying direction of the linear motor; an arc-shaped guide plate 1 is provided on the top of the detection plate mounting bracket; the top surface of the arc-shaped guide plate 1 close to one end of the linear motor is higher than the top surface of the linear motor, and can guide and gradually lift the running slide;

[0016] The over-proximity detection mechanism includes a detection plate and an emergency trigger switch; the middle portion of the detection plate is rotatably mounted on the detection plate mounting bracket; the top end of the detection plate extends upward to above the arc-shaped guide plate to form a trigger end, and the slide can abut against and push the trigger end to drive the detection plate to rotate; the detection plate is transmission-connected to the emergency trigger switch to turn on the emergency trigger switch when rotating; the emergency trigger switch is electrically connected to the controller to send an emergency stop signal.

[0017] The beneficial effects of the above technical solution are: the arc-shaped guide plate acts together to buffer the collision of the slide, so that the slide can be gradually lifted along its arc-shaped top surface to avoid direct collision with the side end of the linear motor; and when the slide slides along the upper surface of the arc-shaped guide plate, it will inevitably touch and push the upper end of the detection plate to make the detection plate rotate, and the rotating detection plate turns on the emergency trigger switch to make it send an emergency stop signal; the detection plate acts as a mechanical switch for shutdown control, which improves the reliability of anti-collision.

[0018] As a further improvement of the above technical solution, the anti-collision guide lifting assembly also includes an anti-collision guide assembly; the anti-collision guide assembly is installed on the frame and is located on the side of the detection plate mounting bracket away from the linear motor, and an arc-shaped guide plate 2 is provided on the top of the anti-collision guide assembly; the arc-shaped guide plate 2 is smoothly connected with the arc-shaped guide plate 1 to jointly form the arc-shaped guide plate structure.

[0019] The beneficial effect of the above technical solution is that the arc-shaped guide plate 2 and the arc-shaped guide plate 1 are smoothly connected to form a longer arc-shaped guide and lifting track, further mitigating the impact of the slide.

[0020] As a further improvement of the above technical solution, it also includes a mounting frame; a mounting hole is set at the upper end of the frame; the mounting frame blocks the mounting hole correspondingly and one end of it is hinged on the frame, and the other end of it is detachably connected to the frame; the detection plate mounting bracket and the lifting adjustment mechanism are both installed on the upper end of the mounting frame; the mounting frame can be flipped open to the bottom of the frame to construct a maintenance work area corresponding to the bottom of the frame.

[0021] The beneficial effects of the above technical solution are: the detection plate mounting bracket and the lifting and adjusting mechanism are both installed at the upper end of the mounting frame. After the other end of the mounting frame is disassembled from the frame, the mounting frame can be flipped downward and opened, so that the detection plate mounting bracket, the arc-shaped guide plate installed on the detection plate mounting bracket, the proximity detection mechanism, the lifting and adjusting mechanism and the linear motor installed on the lifting and adjusting mechanism are all moved out to the bottom of the frame, and a maintenance work area is constructed under the frame for maintenance personnel to carry out maintenance and maintenance operations, that is, convenient maintenance and maintenance of various components can be achieved without disassembling the slide.

[0022] As a further improvement of the above technical solution, a gas spring is installed at the other end of the mounting frame to drive the mounting frame to elastically return to the flipped open state.

[0023] The beneficial effect of the above technical solution is that after the maintenance is completed, the mounting frame can be quickly restored to its original position under the action of the gas spring, and the maintenance personnel can connect the other end of the mounting frame to the frame. The gas spring makes it more time-saving and labor-saving to flip the mounting frame.

[0024] As a further improvement of the above technical solution, the lifting and lowering adjustment mechanism includes a driving motor, a main transmission wheel, a secondary transmission wheel, a transmission structure fixing frame, a transmission screw, a transmission screw sleeve and a lifting frame; the driving motor and the transmission structure fixing frame are both installed at the bottom end of the mounting frame, the main transmission wheel is coaxially sleeved on the rotating shaft of the driving motor, one end of the transmission screw is rotatably connected to the transmission structure fixing frame, the secondary transmission wheel is coaxially sleeved on the transmission screw and is connected to the main transmission wheel in transmission engagement; the other end of the transmission screw movably passes through the mounting frame and is threadedly connected to the transmission screw sleeve; the lifting frame is fixed on the transmission screw sleeve; the linear motor is installed on the lifting frame.

[0025] The beneficial effects of the above technical solution are: the driving motor drives the main transmission wheel to rotate, the main transmission wheel drives the auxiliary transmission wheel to rotate, the auxiliary transmission wheel drives the transmission screw to rotate, and the rotating transmission screw can make the transmission screw sleeve rise and fall along the length direction of the transmission screw; the rising and falling transmission screw sleeve further drives the lifting frame to rise and fall, thereby realizing the lifting and lowering control of the linear motor installed on the lifting frame.

[0026] As a further improvement of the above technical solution, the auxiliary transmission wheel, the transmission screw and the transmission screw sleeve are all multiple.

[0027] The plurality of auxiliary transmission wheels are evenly distributed along the circumference of the main transmission wheel and are all meshed with the main transmission wheel; one ends of the plurality of transmission screws are rotatably connected to the transmission structure fixing frame, and the plurality of auxiliary transmission wheels are coaxially sleeved and fixed on the plurality of transmission screws one by one; the other ends of the plurality of transmission screws movably penetrate the mounting frame and are threadedly connected to the plurality of transmission screw sleeves one by one; the plurality of transmission screw sleeves are fixedly connected to the lifting frame.

[0028] The beneficial effects of the above technical solution are: multiple transmission screws jointly construct the lifting and lowering guide structure of the linear motor, which has good stability; the driving motor synchronously drives the transmission screw to rotate through the main transmission wheel, thereby realizing precise lifting and lowering control of the linear motor, which can facilitate the adjustment of the installation distance between the linear motor and the slide, and can also control the linear motor to descend to avoid the slide in an emergency.

[0029] As a further improvement of the above technical solution, it also includes a distance sensor component, which is arranged below the slide to monitor the running height and tilt angle of the slide, and the distance sensor component is electrically connected to the controller.

[0030] The beneficial effect of the above technical solution is that the distance measuring sensor component can measure the running height and tilt angle of the slide without contact, so as to provide early warning and monitoring of the operation status of the slide.

[0031] Another aspect of the present invention provides a fault-tolerant method for a linear motor drive assembly device with a high fault-tolerant rate, comprising the following fault-tolerant measures:

[0032] S1: Set up the too-close distance detection and triggering mechanical switch between the slide and the linear motor: install the too-close detection mechanism on the frame, and make the trigger end of the too-close detection mechanism arranged at a height lower than the normal operating height of the slide and higher than the top surface height of the linear motor; judge whether the distance between the slide and the linear motor is too close by whether the running slide touches the trigger end; when the running height of the slide is lower than the arrangement height of the trigger end and touches the trigger end, the too-close detection mechanism sends an emergency stop signal to the controller, and the controller controls the linear motor to stop urgently;

[0033] S2. Set up anti-collision guide: arrange anti-collision guide lifting components on the frame at the beginning of the conveying direction of the linear motor; when the running height of the slide is lower than the top surface of the linear motor, the guide plate structure is used to guide and lift the slide height to prevent the slide from colliding with the linear motor;

[0034] S3: Set up a distance adjustment mechanism between the slide and the linear motor: arrange a lifting and adjusting mechanism on the frame below the linear motor; after the controller receives the emergency stop signal sent by the too-close detection mechanism, it sends a command signal to the lifting and adjusting mechanism to lower the height of the linear motor. The lifting and adjusting mechanism controls the linear motor to descend to avoid the running slide to prevent collision.

[0035] As a further improvement of the above technical solution, the following fault tolerance measures are also included:

[0036] S4: a distance measuring sensor assembly for monitoring the distance between the slide and the linear motor is arranged below the slide, and the distance between the slide and the linear motor and the tilt angle of the slide are monitored in real time;

[0037] S5: Setting a flippable mounting frame to construct a flip maintenance structure: During maintenance, flip the mounting frame downward to rotate the lifting adjustment mechanism and the detection plate mounting bracket installed on the mounting frame out of the rack, and construct a maintenance work area under the corresponding rack.

[0038] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a high fault tolerance linear motor drive assembly device and a fault tolerance method, which have the following advantages and beneficial effects:

[0039] 1. The lifting and lowering adjustment mechanism of the present invention can automatically adjust the distance between the linear motor and the slide, thereby ensuring the safe distance installation requirements between the linear motor and the slide.

[0040] 2. In order to avoid collision between the linear motor and the slide, the present invention provides a high fault tolerance linear motor drive assembly with four protection measures. The first protection measure is to set a distance measuring sensor assembly. The distance measuring sensor assembly has three functions. First, it is used to detect the accuracy of the height position of the linear motor when the drive device is installed. Secondly, it is used to monitor the change in the distance between the slide and the linear motor during the operation of the drive device. Finally, it monitors the inclination angle of the slide perpendicular to the conveying direction. When it is detected that the distance between the slide and the linear motor is lower than the set value or the inclination angle of the slide exceeds the set value, the vehicle will stop, alarm, and wait for maintenance. The second protection measure is to set an emergency trigger switch to control the on and off of the emergency trigger switch through mechanical touch. When mechanical touch occurs, the on and off state of the emergency trigger switch changes, and it is judged that the distance between the linear motor and the slide is too close, that is, the vehicle will stop, alarm, and wait for maintenance. The third protection measure is the aforementioned lifting and adjusting mechanism. When the aforementioned first or second protection measures are triggered, the automatic adjustment mechanism will move the linear motor downward away from the slide to avoid such collisions. Figure 1 The fourth protection measure is to add an anti-collision guide lifting component at the front end relative to the movement direction of the slide. When the slide deviates too much in the direction of the linear motor, the guide plate structure will guide the slide away from the linear motor, allowing the slide to slide close to the linear motor, so that the linear motor will not be fundamentally damaged.

[0041] 3. Aiming at the problem of convenient maintenance, the present invention designs a flip structure of the mounting frame, which can rotate the linear motor as a whole out of the original working position and can quickly restore it with the help of the elastic force of the gas spring after maintenance is completed.

[0061] In the conveying equipment that uses linear motor 7 to drive slide 8 to move and transport luggage and other items, slide 8 is horizontally arranged and slidably connected to the guide rail 91 of running track 9 through guide wheel 81. Linear motor 7 is connected to slide 8 to drive slide 8 to move and transport above linear motor 7. The mover of linear motor 7 is fixedly connected and drives slide 8. There are two forms of driving structure of the mover and stator of linear motor 7: one is that the mover is parallel to the upper end of the stator, and there are high requirements for the installation and operation accuracy of the distance between slide 8 and the upper end surface of the stator and the inclination of slide 8, see Figure 1 The other is that the mover is inserted vertically into the gap of the vertically arranged stator, which mainly requires the installation and operation accuracy of the slide 8 inclination, see Figure 2 Drive mode two is shown.

[0062] like Figures 3 to 12 As shown, a high fault tolerance linear motor drive assembly device comprises:

[0063] A frame 1, which is mounted on a running track 9 and is arranged below a linear motor 7;

[0064] An anti-collision guide lifting assembly 2 is installed on the frame 1 and arranged at the beginning of the conveying direction of the linear motor 7; a guide plate structure 23 is provided on the top of the anti-collision guide lifting assembly 2, and the guide plate structure 23 is configured to slide against and guide the lifting slide 8 to the top of the corresponding linear motor 7 when the operating height of the slide 8 is lower than its preset height;

[0065] The over-proximity detection mechanism 3 is mounted on the frame 1; the trigger end 311 of the over-proximity detection mechanism 3 is arranged above the guide plate structure 23; when the slide 8 slides over the upper surface of the guide plate structure 23, it can abut against the trigger end 311, so that the over-proximity detection mechanism 3 sends an emergency stop signal;

[0066] A lifting adjustment mechanism 4, which is mounted on the frame 1 and is located below the linear motor 7. The lifting end of the lifting adjustment mechanism 4 is connected to the linear motor 7 to adjust the lifting of the linear motor 7;

[0067] The controller is electrically connected to the over-proximity detection mechanism 3 and the lifting and adjusting mechanism 4, so as to control the linear motor 7 to descend to avoid the slide 8 through the lifting and adjusting mechanism 4 when receiving the emergency stop signal sent by the over-proximity detection mechanism 3.

[0068] When the high-tolerance linear motor drive assembly device of this embodiment is used, the trigger end 311 of the proximity detection mechanism 3 is arranged higher than the guide plate structure 23. When the operating height of the slide 8 gradually decreases and approaches the preset height, the trigger end 311 is preferentially touched, so that the proximity detection mechanism 3 sends an emergency stop signal, and then the controller controls the linear motor 7 to stop and stop driving the slide 8; when the height of the running slide 8 changes greatly, the operating height is lower than the preset height and preferentially touches the guide plate structure 23, the anti-collision guide lifting component The guide plate structure 23 of 2 can guide the slide 8 to move and raise the height of the slide 8 to prevent the slide 8 from colliding with the linear motor 7; and when the slide 8 slides along the upper surface of the guide plate structure 23, it will inevitably touch the trigger end 311 to stop the slide 8, so as to prevent the slide 8 from crossing the guide plate structure 23 and hitting the linear motor 7; after receiving the emergency stop signal sent by the too-close detection mechanism 3, the controller can control the linear motor 7 to urgently descend through the lifting and adjusting mechanism 4 to avoid the slide 8, so as to prevent the slide 8 from hitting the linear motor 7 when it inertia overrushes to the top of the linear motor 7.

[0069] In some embodiments, the anti-collision guide lifting assembly 2 includes a detection plate mounting bracket 21 arranged at the starting end of the conveying direction of the linear motor 7; an arc-shaped guide plate 211 is provided on the top of the detection plate mounting bracket 21; the top surface of the arc-shaped guide plate 211 close to one end of the linear motor 7 is higher than the top surface of the linear motor 7, and can guide and gradually lift the running slide 8;

[0070] The over-proximity detection mechanism 3 includes a detection plate 31 and an emergency trigger switch 32; the middle part of the detection plate 31 is rotatably mounted on the detection plate mounting bracket 21 through a detection plate shaft 312 arranged horizontally and vertically in the conveying direction of the slide 8; the top end of the detection plate 31 extends upward to above the arc-shaped guide plate 211 to form a trigger end 311, and the slide 8 can abut and push the trigger end 311 to drive the detection plate 31 to rotate; the detection plate 31 is transmission-connected to the emergency trigger switch 32 to turn on the emergency trigger switch 32 when rotating; the emergency trigger switch 32 is electrically connected to the controller to send an emergency stop signal.

[0071] The arc-shaped guide plate 211 plays the role of buffering the collision of the slide 8, and can make the slide 8 gradually rise along its arc-shaped top surface to avoid directly colliding with the side end of the linear motor 7; and when the slide 8 slides along the upper surface of the arc-shaped guide plate 211, it will inevitably touch and push the upper end of the detection plate 31 to make the detection plate 31 rotate, and the rotating detection plate 31 turns on the emergency trigger switch 32 to make it send an emergency stop signal; the detection plate 31 serves as a mechanical switch for shutdown control, which improves the reliability of anti-collision.

[0072] Specifically, the proximity detection mechanism 3 also includes a spring 33, an electrical installation base plate 34 and an electrical support 35; the electrical installation base plate 34 is fixedly mounted on the upper end of the frame 1, and the electrical support 35 is mounted on the upper end of the electrical installation base plate 34; the emergency trigger switch 32 is fixedly mounted on the electrical support 35 and corresponds to a side surface of the lower end of the detection plate 31; one end of the spring 33 is fixedly connected to the lower end of the detection plate 31, and the other end is fixedly connected to the electrical support 35, so as to elastically press the lower end of the detection plate 31 against the emergency trigger switch 32, so that the emergency trigger switch 32 is in a normally closed or normally open state under force. When the distance between the slide 8 and the linear motor 7 is too close and it slides over the detection plate 31, the slide 8 will push the trigger end 311 of the detection plate 31 and overcome the pulling torque of the spring 33, so that the detection plate 31 rotates around the detection plate shaft 312 in the opposite direction of the pulling direction of the spring 33, thereby changing or separating the force state of the detection plate 31 and the emergency trigger switch 32, and switching the emergency trigger switch 32 to the normally closed or normally open state, thereby feeding back the state of the emergency to the controller.

[0073] In some embodiments, the anti-collision guide lifting assembly 2 also includes an anti-collision guide assembly 22; the anti-collision guide assembly 22 is installed on the frame 1 and is located on the side of the detection plate mounting bracket 21 away from the linear motor 7, and an arc-shaped guide plate 221 is provided on the top of the anti-collision guide assembly 22; the arc-shaped guide plate 221 is smoothly connected with the arc-shaped guide plate 1 211 to jointly form an arc-shaped guide plate structure 23.

[0074] The arc-shaped guide plate 221 and the arc-shaped guide plate 1 211 are smoothly connected to form a longer arc-shaped guide and lifting track, further mitigating the impact of the slide 8.

[0075] Specifically, there are two arc-shaped guide plates 211, which are symmetrically arranged on both sides of the detection plate mounting bracket 21 in the width direction; the detection plate 31 is arranged between the two corresponding arc-shaped guide plates 211; the upper part of the arc-shaped guide plate 221 and the middle part of the detection plate 31 in the width direction have avoidance gaps for avoiding the mover of the linear motor 7.

[0076] In some embodiments, a mounting frame 5 is also included; a mounting hole 11 is set at the upper end of the frame 1; the mounting frame 5 blocks the mounting hole 11 and one end of the mounting frame 5 is hinged to the frame 1 through a hinge shaft 54, and the other end of the mounting frame 5 is detachably connected to the frame 1 through a fixing screw 52; the detection plate mounting bracket 21 and the lifting adjustment mechanism 4 are both installed at the upper end of the mounting frame 5; the mounting frame 5 can be flipped open to the bottom of the frame 1 to construct a maintenance work area under the corresponding frame 1.

[0077] The detection plate mounting bracket 21 and the lifting and adjusting mechanism 4 are both mounted on the upper end of the mounting frame 5. After removing the fixing screws 52 to separate the other end of the mounting frame 5 from the frame 1, the mounting frame 5 can be flipped downward to open, so that the detection plate mounting bracket 21, the arc-shaped guide plate 211 mounted on the detection plate mounting bracket 21 and the over-proximity detection mechanism 3, the lifting and adjusting mechanism 4 and the linear motor 7 mounted on the lifting and adjusting mechanism 4 are all moved out to the bottom of the frame 1, and a maintenance work area is constructed under the frame 1 for maintenance personnel to perform maintenance and repair operations, that is, convenient maintenance and repair of various components can be achieved without disassembling the slide.

[0078] In some embodiments, a gas spring 51 is installed at the other end of the mounting frame 5 to elastically return the mounting frame 5 to the flipped open state.

[0079] After the maintenance is completed, the mounting frame 5 can be quickly restored to its original position under the action of the gas spring 51, and the maintenance personnel can simply connect the other end of the mounting frame 5 to the rack 1. The gas spring 51 makes it more time-saving and labor-saving to flip the mounting frame 5.

[0080] Specifically, the mounting hole 11 is a rectangular strip hole opened along the length direction of the frame 1. A gas spring mounting bracket 12 is fixed to one end of the bottom end of the frame 1 corresponding to the length direction of the mounting hole 11, and a gas spring mounting plate 53 is fixed to the bottom surface of the other end of the mounting bracket 5; one end of the gas spring 51 is hinged to the gas spring mounting bracket 12, and the other end is hinged to the gas spring mounting plate 53.

[0081] In some embodiments, the lifting and adjusting mechanism 4 includes a driving motor 41, a main transmission wheel 42, a secondary transmission wheel 43, a transmission structure fixing frame 44, a transmission screw 45, a transmission screw sleeve 46 and a lifting frame 47; the driving motor 41 and the transmission structure fixing frame 44 are both installed at the bottom end of the mounting frame 5, the main transmission wheel 42 is coaxially sleeved on the rotating shaft of the driving motor 41, one end of the transmission screw 45 is rotatably connected to the transmission structure fixing frame 44, the secondary transmission wheel 43 is coaxially sleeved on the transmission screw 45 and is connected to the main transmission wheel 42 in transmission engagement; the other end of the transmission screw 45 movably passes through the mounting frame 5 and is threadedly connected to the transmission screw sleeve 46; the lifting frame 47 is fixed on the transmission screw sleeve 46; the linear motor 7 is installed on the lifting frame 47.

[0082] The driving motor 41 drives the main transmission wheel 42 to rotate, the main transmission wheel 42 drives the auxiliary transmission wheel 43 to rotate, and the auxiliary transmission wheel 43 drives the transmission screw 45 to rotate. The rotating transmission screw 45 can make the transmission screw sleeve 46 rise and fall along the length direction of the transmission screw 45; the rising and falling transmission screw sleeve 46 further drives the lifting frame 47 to rise and fall, thereby realizing the lifting and lowering control of the linear motor 7 installed on the lifting frame 47.

[0083] In some embodiments, there are multiple auxiliary transmission wheels 43, transmission screws 45, and transmission screw sleeves 46.

[0084] Multiple auxiliary transmission wheels 43 are evenly distributed along the circumference of the main transmission wheel 42 and are all connected in transmission meshing with the main transmission wheel 42; one end of multiple transmission screws 45 are rotatably connected to the transmission structure fixing frame 44, and multiple auxiliary transmission wheels 43 are coaxially sleeved on the multiple transmission screws 45 in a one-to-one manner; the other ends of multiple transmission screws 45 all movably penetrate the mounting frame 5 and are threadedly connected to multiple transmission screw sleeves 46 in a one-to-one manner; multiple transmission screw sleeves 46 are fixedly connected to the lifting frame 47.

[0085] A plurality of transmission screws 45 together form a lifting and lowering guide structure for the linear motor 7, which has good stability; the driving motor 41 synchronously drives the transmission screw 45 to rotate through the main transmission wheel 42, thereby realizing precise lifting and lowering control of the linear motor 7, which can facilitate the adjustment of the installation distance between the linear motor 7 and the slide 8, and can also control the linear motor 7 to descend to avoid the slide 8 in an emergency.

[0086] Specifically, the lifting structure outer cover 48 is fixed by a cover buckle at the bottom end of the mounting frame 5, and the main transmission wheel 42, the auxiliary transmission wheel 43 and the transmission structure fixing frame 44 are all located inside the lifting structure outer cover 48; the driving motor 41 is fixedly installed at the bottom end of the lifting structure outer cover 48, and its rotating shaft movably passes through the inside of the lifting structure outer cover 48 and is connected to the main transmission wheel 42.

[0087] In some embodiments, a distance measuring sensor assembly 6 is also included. The distance measuring sensor assembly 6 is arranged below the slide 8 to monitor the running height and tilt angle of the slide 8. The distance measuring sensor assembly 6 is electrically connected to the controller.

[0088] The distance measuring sensor assembly 6 can measure the running height and tilt angle of the slide 8 without contact, so as to provide early warning and monitoring of the running condition of the slide 8 .

[0089] Specifically, the distance sensor assembly 6 is divided into two groups, each group is composed of two distance sensors 61, and the two distance sensors 61 in one group are installed on the side of the electrical bracket 35 close to the linear motor 7, and are arranged at intervals along the width direction of the slide 8. The sensing ends of the two distance sensors 61 are arranged upward to detect the running height on both sides of the width direction of the lower surface of the slide 8 passing above it, and after comparing with the installation height of the linear motor 7, the distances x1 and x2 between the two sides of the width direction of the lower surface of the slide 8 and the upper end surface of the linear motor 7 can be detected in real time. Another group of distance sensors 61 can be arranged on the running track 9 on the side of the anti-collision guide assembly 22 away from the detection plate mounting bracket 21, so as to provide early warning and monitor the running height of the slide 8 before the slide 8 moves close to the linear motor 7.

[0090] Another aspect of the present invention provides a fault-tolerant method for a linear motor drive assembly device with a high fault-tolerant rate, comprising the following fault-tolerant measures:

[0091] S1: Setting a too-close distance detection and triggering mechanical switch between the slide 8 and the linear motor 7: Installing the too-close detection mechanism 3 on the frame 1, and making the arrangement height of the trigger end 311 of the too-close detection mechanism 3 lower than the normal operating height of the slide 8 and higher than the top surface height of the linear motor 7; judging whether the distance between the slide 8 and the linear motor 7 is too close by whether the running slide 8 touches the trigger end 311; when the running height of the slide 8 is lower than the arrangement height of the trigger end 311 and touches the trigger end 311, the too-close detection mechanism 3 sends an emergency stop signal to the controller, and the controller controls the linear motor to stop urgently;

[0092] S2. Set up anti-collision guide: arrange anti-collision guide lifting assembly 2 on the frame 1 at the beginning of the conveying direction of the linear motor 7; when the running height of the slide 8 is lower than the top surface of the linear motor 7, the guide plate structure 23 is used to guide and lift the height of the slide 8 to prevent the slide 8 from colliding with the linear motor 7;

[0093] S3: Set up a distance adjustment mechanism between the slide 8 and the linear motor 7: arrange the lifting and lowering adjustment mechanism 4 on the frame 1 below the linear motor 7; after the controller receives the emergency stop signal sent by the too-close detection mechanism 3, it sends a command signal to the lifting and lowering adjustment mechanism 4 to lower the height of the linear motor 7. The lifting and lowering adjustment mechanism 4 controls the linear motor 7 to descend to avoid the running slide 8 to prevent collision.

[0094] In some embodiments, the following fault tolerance measures are also included:

[0095] S4: a distance measuring sensor assembly 6 for monitoring the distance between the slide 8 and the linear motor 7 is arranged below the slide 8 to monitor the distance between the slide 8 and the linear motor 7 and the tilt angle of the slide in real time;

[0096] S5: Setting a flippable mounting frame 5 to construct a flip maintenance structure: During maintenance, flip the mounting frame 5 downward to rotate the lifting adjustment mechanism 4 and the detection plate mounting bracket 21 installed on the mounting frame 5 out of the rack 1, and construct a maintenance work area under the corresponding rack 1.

[0097] Specifically, by Figures 3 to 12As shown, during installation, the linear motor 7 is fixedly mounted on the lifting frame 47, and the frame 1 and the device as a whole are installed on the running track 9 and between the two corresponding guide rails. The preliminary installation and debugging contents include: installation and debugging of the anti-collision guide lifting component 2 and the too-close detection mechanism 3, installation and debugging of the lifting adjustment mechanism 4, and fixing screws 52 to connect the mounting frame 5 and the frame 1. The height position of the linear motor 7 is adjusted to a rough position, and then a common flat plate is placed on the linear motor 7 so that the distance from the measuring point of the distance sensor 61 to the upper surface of the linear motor 7 (i.e., the lower surface of the common flat plate) can be detected by the distance sensor 61. The controller compares and judges the detected distance data with the set threshold value to lift and adjust the linear motor 7 to a precise position. The judgment method can be as follows:

[0098] Example 1:

[0099] ①Altitude judgment and adjustment: Under normal circumstances,

[0100] like The linear motor automatically adjusts the rise

[0101] like The linear motor is automatically adjusted to descend

[0102] like or The alarm will remind the installer to readjust

[0103] ② Tilt judgment:

[0104] like or The alarm will remind the installer to adjust

[0105] a, b, c, d, e, and f are the set safety values.

[0106] Once all the above steps are completed, the preliminary debugging is complete.

[0107] During normal operation, the distance sensor 61 continues to work to detect the distance between the slide 8 and the linear motor 7. During this process, the guide wheel 81 may wear, the guide rail 91 may be compressed and deformed, and the slide 8 itself may deform, which may cause the distance between the slide 8 and the linear motor 7 to become closer, or the slide 8 may tilt. When the distance between the slide 8 and the linear motor 7 is too close, the slide and the linear motor may collide in the first drive mode; when the slide tilts, the metal plate (motor) used for the inductive drive may collide with the linear motor in the second drive mode. Therefore, the distance detection between the slide 8 and the linear motor 7 by the distance sensor 61 can provide early warning and realize automatic adjustment within a certain range. The specific implementation method is:

[0108] Example 2:

[0109] ①Altitude judgment and adjustment: Under normal circumstances,

[0110] like The linear motor automatically adjusts the rise

[0111] like The linear motor is automatically adjusted to descend

[0112] like or Then the alarm stops and waits for maintenance

[0113] a1, b1, e1, and f1 are set safety values.

[0114] ② Tilt judgment and alarm:

[0115] like or Then the alarm will sound, the car will stop and wait for maintenance.

[0116] In particular, a distance measuring sensor 61 can be added to the track along the moving direction of the slide and located at the front end of the driving assembly device proposed by the present invention, such as Figure 3 As shown, the distance measuring sensor 61 is placed in front to monitor in advance, so as to facilitate instant adaptive lifting height adjustment.

[0117] In order to prevent the distance measuring sensor 61 from not feeding back fault information in time, an over-close detection mechanism 3 is added to detect and trigger when the distance between the slide 8 and the linear motor 7 is too close, and a mechanical structure detection mode is adopted, wherein the arc surface of the arc guide plate 221 at the top of the anti-collision guide assembly 22 extends and smoothly transitions with the arc surface of the arc guide plate 1 211 of the detection plate mounting bracket 21, the height α of the top of the detection plate 31 is slightly higher than the highest point β of the arc surface of the arc guide plate 1 211, and the arc surface of the arc guide plate 1 211 is The highest point β is slightly higher than the top surface γ of the linear motor. When the distance between the slide 8 and the linear motor 7 is too close, the slide 8 will follow the arc surface of the arc guide plate 221 and the arc guide plate 1 211. During the process of following, the detection plate 31 will rotate around the detection plate shaft 312, so that the pressure state of the emergency trigger switch 32 will change, and the emergency will be triggered. Then the controller will automatically adjust the linear motor 7 to the maximum extent, so that the distance between the slide 8 and the linear motor 7 is increased to avoid the linear motor 7 from being damaged by collision, and at the same time, the alarm will be sounded to stop the car and wait for maintenance.

[0118] During the maintenance process, the maintenance personnel loosen the fixing screw 52 and move the other end of the mounting frame 5, so that the mounting frame 5 and the parts installed on the mounting frame 5 rotate as a whole around the rotation axis, so that the mounting frame 5 and the parts installed on the mounting frame 5 rotate as a whole and move out. After being moved out, it is convenient for maintenance. After the maintenance is completed, it is slowly released. Due to the action of the gas spring 51, it can be quickly restored. After tightening the fixing screw 52, ​​the maintenance work can be completed. Fig.13 A schematic diagram of the working process of the high fault tolerance linear motor drive assembly device of the present invention is given.
