Quick linkage shrinking mechanism, shrinking method and parts processing equipment in the mechanism

Abstract

The invention discloses a fast linkage retraction mechanism, a retraction method and a part processing device in the mechanism. The retraction mechanism includes two core components: a wind-adaptive flip actuator and a linkage descending mechanism. The wind-adaptive flip actuator realizes the directional flipping of the display frame through an elastic telescopic member, a sliding hinge shaft and a limit connecting rod. Under the action of wind, the telescopic member contracts to drive the rotating shaft to move, so that the display frame is flipped from an upright state to a horizontal folded state. The linkage descending mechanism includes a linkage belt arranged at the hinge of the rotating arm. When the display frame flips, the linkage belt changes from a taut state to a loose state, releasing the locking state of the rotating arm. Under the action of its own weight, the rotating arm quickly rotates downward to lower the display frame from a high position to a low position. The invention also provides an automatic production line for processing parts of a display frame mounting seat. The production line adopts a linear transmission mechanism and is provided with a clamping and flipping component, which can automatically and continuously perform processing on both sides, thereby improving production efficiency.

Description

[0002] The fast linkage retracting mechanism of the present invention can realize the rapid folding and storage of the display frame, and improve the wind resistance of the equipment; the matching automated processing equipment realizes the efficient and precise processing of the display frame mounting seat, greatly improving the manufacturing efficiency. The present invention integrates and uses multiple technologies such as machinery, automation, and materials, and provides an effective solution for improving the wind resistance of display equipment and significantly improving manufacturing efficiency. Background Art

[0003] With the promotion of intelligent and modular design concepts, the demand for rapid installation and disassembly of various types of equipment is increasing. For example, in temporary scenes such as outdoor activities and touring performances, it is necessary to quickly build and dismantle smart display equipment. Such equipment needs to be installed quickly and can automatically retract under the influence of external environments such as wind changes to ensure structural stability and safety.

[0004] Traditional outdoor display equipment mostly adopts a large-volume integral fixed or manually folding structure, such as the invention patent publication number CN 116072018 A, which is a promotional display stand that is easy to fold and store. The patent adopts a push mechanism and a folding mechanism to adjust the display layout to meet different marketing display needs. However, this type of display stand has the problem of a complex folding and storage structure and poor wind resistance. When encountering strong winds, the entire display stand may be blown down by the wind, causing secondary damage to surrounding personnel and facilities, and the safety of use cannot be guaranteed.

[0005] To solve this problem, a linkage retraction mechanism for wind-resistant display equipment has been designed. This mechanism is used in outdoor display equipment to achieve rapid and intelligent retraction to protect the display equipment. Part of the components in the entire linkage retraction mechanism are known modules that can be purchased on the market, such as multi-section support arms, and the other part are parts with smaller structures, which can be easily automated. There are also parts with larger individual volumes, such as the display frame mounting seat, which has a large overall volume and requires processing of holes on both sides and the fixing screws in the holes for assembly. Since it is located on two opposite sides, larger devices are required to achieve automated processing of the assembly line, so the production line requires a large investment cost.

[0006] In order to reduce the processing cost of the display frame mounting seat, it is necessary to design a simple and efficient assembly line for processing the display frame mounting seat. Summary of the invention

[0007] In view of the above problems, the present invention designs a rapid linkage retracting mechanism, which can quickly fold and store the display frame through wind monitoring to avoid damage by strong winds; and also designs an automatic processing equipment for the display frame mounting seat with automatic transportation, positioning clamping, and two-side flipping processing, so as to realize rapid and accurate processing of the display frame and greatly improve the wind resistance and manufacturing efficiency of the display frame.

[0008] The invention objective of the present invention is achieved through the following technical solution: A fast linkage retracting mechanism is arranged in a support arm assembly composed of a first rotating arm, a second rotating arm and a third rotating arm, comprising:

[0020] In view of the above problems, the present invention further provides a contraction method of a rapid linkage contraction mechanism, wherein the rapid linkage contraction mechanism comprises: a support arm assembly, a flip actuator, and a linkage descending mechanism, and the method comprises:

[0021] When the wind force reaches a preset threshold, the wind force pushes the elastic expansion member set in the flip actuator to contract, driving the hinge shaft and the mounting seat to flip quickly, so that the display frame can be flipped from the upright state to the horizontal folded state. This method can effectively avoid structural damage to the display frame under strong wind conditions by monitoring the wind force to trigger contraction.

[0022] Preferably, the hinge shaft of the flip actuator is hinged at both ends to the display frame mounting seat, and the movement direction is rotation around the Z axis; a limit link is also provided, one end of which is slidably connected to the guide groove and the other end is hinged to the display frame mounting seat, for limiting the rotation of the display frame mounting seat. The limit link plays a supporting role and can accurately control the storage angle of the display frame to avoid excessive flipping.

The descending mechanism allows the display frame to be quickly stored in a low position, reducing the impact of wind.

[0025] Preferably, the stop block is disengaged from the meshing teeth on the third rotating arm by the elastic force of multiple spring sheets arranged at different circumferential positions. The spring elastic force design enables the stop block to be disengaged smoothly and achieve rapid contraction.

[0070] Example 1

[0071] See all attached drawings

[0072] The quick-link retracting mechanism of this embodiment is arranged in a multi-section support arm assembly 2 with adjustable height and angle. Usually, the first section of the support arm assembly 2 is fixed to the wall or the ground through a base or a frame, and the last section of the support arm assembly 2 is installed on the display frame 5 through the components in the support arm assembly 2.

[0073] The quick linkage retraction mechanism includes:

[0074] A wind-adaptive flip actuator 3. The flip actuator 3 is one of the core components of the retracting mechanism, which realizes the installation and automatic flipping functions of the display frame 5;

[0075] A linkage descending mechanism 4. When the wind force exceeds the threshold, it can quickly trigger the support arm assembly to retract, so that the display frame moves down to close to the ground, greatly reducing the wind load overturning arm. This mechanism cooperates with the flipping mechanism to further enhance the responsiveness to wind force and is a key component for achieving fast and intelligent wind-resistant retraction.

[0076] By setting a simple and reliable linkage descending module and cooperating with the flip module, this embodiment realizes the rapid positioning and adjustment of the display frame, so that it can remain stable in a strong wind environment and avoid tipping over. The double insurance design ensures the safety of the display equipment.

[0077] The support arm assembly 2 is composed of multiple rotating arms connected in series, including a first rotating arm 21, a second rotating arm 22, and a third rotating arm 23. The flip actuator 3 is arranged in the third rotating arm 23. In order to clearly describe the flip mechanism, a coordinate system is established in this embodiment for explanation.

[0078] Display frame mounting seat 31, which is mounted on the third arm 23, can only rotate around the Z axis;

[0079] 2. An elastic telescopic member 32 with a U-shaped groove at one end, and a conversion transition surface 321 at the other end of the elastic telescopic member 32, which can slide relative to the third rotating arm 23 along the X-axis; the U-shaped groove is slidably matched with the corresponding guide groove in the third rotating arm 23 to form a parallel guide groove 06; the elastic telescopic member 32 provides a reset force through a spring;

[0080] 3. A hinge shaft 33, the middle part of which is arranged in the parallel guide groove 06, with both ends exposed and hinged to the display frame mounting seat 31, and the hinge shaft 33 can slide in the X-axis direction;

[0081] 4. The limiting link 34 has one end slidably / lockably connected to the parallel guide groove 06 by setting a sliding seat 07, and the other end is hinged to the display frame mounting seat 31; it limits the rotation of the display frame mounting seat 31 in the display state and the retracted state.

[0082] The mechanism realizes the directional rotation of the mounting seat 31 through the hinge shaft 33, the limit connecting rod 34 and the parallel guide groove 06. Upward flipping is used for display; downward flipping is restricted to avoid collision with other parts. This simple mechanism realizes the controllable flipping of the display frame. The function of the limit connecting rod 34 is to pull or support the display frame 5 so that the hinged mounting shaft 33 is maintained in two stable positions; the setting position of the limit connecting rod 34 enables the display frame 5 to flip upward only. This is because when the display frame 5 flips downward, the hinged mounting shaft 33 needs to move toward the far end in the parallel guide groove 06, and the far end is restricted by the closed end of the channel. This design is because the space for the display frame 5 to flip downward will be limited by other components such as the second rotating arm, and the two will collide, so it is not allowed to flip downward.

[0083] The key to the wind-adaptive flipping of the flip actuator is the matching assembly of the components. During assembly, the elastic telescopic member 32 should be fully extended first, and the sliding seat 07 should be adjusted so that the hinged mounting shaft 33 is located at the far end of the guide groove 06, leaving a small gap between the conversion transition surface 321 and the display frame mounting seat 31.

[0084] In this way, under normal circumstances, the elastic force of the elastic telescopic member 32 will keep the rotating shaft 33 at the far end position, and the display frame mounting seat 31 will be in an upright display state. When the wind force in the environment increases, the wind force will overcome the elastic force and push the elastic telescopic member 32 to shrink, and the rotating shaft 33 will move in the guide groove, driving the mounting seat 31 to rotate and flip to the shrinking and folding state.

[0085] Through the cooperation of the elastic expansion member and the rotating mechanism, the sensing and mechanical response to the environmental wind force are realized, so that the display frame can be automatically turned over and retracted. This simple mechanism has a compact structure and reliable movement, which is the core of this embodiment.

[0086] The action principle of the flip actuator is:

[0087] Under normal conditions, the elastic telescopic member 32 is in an extended state, so that the rotating shaft 33 is fixed at the far end, and the display frame is in an upright display position. When the wind force increases, the rotating torque compresses the spring 04 and pushes the elastic telescopic member 32 to contract, and the rotating shaft 33 moves accordingly. As the wind force increases, the compression accumulates to a critical value, and the return force when the spring is released quickly drives the rotating shaft and the mounting seat to rotate and flip, and the display frame folds to a horizontal state. At this time, the limit link 34 enters the upper edge of the conversion surface 321 to prevent complete separation, and the wind load is greatly reduced.

[0088] The mechanism achieves wind sensing and mechanical response through the combination of spring retention and quick release flipping, allowing the display frame to fold and shrink stably and reliably. The conversion surface design facilitates smooth resetting. This simple mechanism is the key to achieving intelligent wind-resistant shrinkage.

[0089] The linkage descending mechanism 4 uses a mechanical linkage method to realize the rapid descending and positioning of the display frame 5. It includes a flexible elastic linkage belt 41 arranged around the hinge of the second rotating arm 22 and the third rotating arm 23, one end of the linkage belt 41 is connected to the flip mechanism 3 through an extended connecting portion 43, and the other end is fixed to the third rotating arm 23. A stop block 44 and a corresponding stop shaft 45 are also provided below the linkage belt 41. The more specific structure of the linkage descending mechanism 4 also includes: a notch 42: arranged at the hinge of the second rotating arm 22 and the third rotating arm 23, for the linkage belt 41 to pass through; an extended connecting portion 43: located on the side of the hinge mounting shaft 33 facing the rotating arm, for connecting the linkage belt 41; one end of the linkage belt 41 is fixed to the third rotating arm 23, and the other end passes through the notch 42 and is connected to the extended connecting portion 43; a stop block 44: having an inverted cone shape, a downward pressing meshing tooth 441 is provided at the bottom, and a spring sheet 442 extending outward is provided in the middle section; the spring sheet 442 causes the stop block 44 to bounce toward the distal direction and constrains the stop block 44 to a certain activity space. The stopper block 44 is located below the linkage belt 41; the stopper shaft 45 is fixed to the third rotating arm 23, and has a surrounding meshing tooth 451 on its outer ring that matches the downward meshing tooth 441; the stopper block mounting portion 46 is a fixed portion disposed on the second rotating arm 22, matching the shape of the stopper block 44, and also includes a mounting portion for the spring sheet 442. Its position corresponds to the surrounding meshing tooth 451.

[0090] When the display frame 5 is in the vertical display state, refer to Figure 1-2 , the linkage belt 41 is in a tensioned state, at which time, the meshing teeth 441 of the stop block 44 mesh with the surrounding meshing teeth 451, so that the third rotating arm 23 is in a locked stable state.

[0091] When the display frame 5 is turned to a horizontal state by the wind, the hinged mounting shaft 33 moves toward the side of the rotating arm, driving the extended connecting portion 43 to move synchronously, so that the linkage belt 41 changes from the original tightened state to the loosened state. At this time, the stopper 44 is disengaged from the meshing state with the surrounding meshing teeth 451 under the action of the spring sheet 442, and the third rotating arm 23 also changes from the locked state to the rotatable state.

[0092] Under the action of its own weight, the third rotating arm 23 rapidly rotates downward around the hinge. This downward rotation process tightens the loosened linkage belt 41 again and closely fits around the hinge. Finally, the display frame 5 moves downward to a low stable state, and the third rotating arm 23 is locked again.

[0093] In this way, the display frame 5 can be rapidly lowered from the high horizontal state to the low vertical state, and can continue to be displayed while avoiding overturning.

[0094] In order to prevent the spring sheet 442 from being easily separated after multiple uses, the middle section of the stop block 44 can be separated into two parts, that is, the spring sheet 442 and the stop block body are separated structures. The two are connected by a hinge or other connection method. In this way, when the spring sheet 442 undergoes elastic deformation, it will not cause the entire stop block 44 to be displaced, thereby ensuring the normal function of the spring sheet 442.

[0095] In addition, the spring sheet 442 can be arranged in a multi-piece distribution mode, that is, multiple spring sheets are arranged at different positions around the stop block 44. This can make the stop block 44 have better balance and stability. The elastic force of each spring sheet can also be optimized and balanced by design.

[0096] The steps of the retraction method of the quick linkage retraction mechanism are as follows:

[0097] 1. In a normal state, the elastic telescopic member 32 is in an extended state, so that the rotating shaft 33 is fixed at the far end, and the display frame is in an upright display position.

[0098] When the wind force increases, the wind force compresses the spring 04 and pushes the elastic telescopic member 32 to contract, and the rotating shaft 33 moves in the parallel guide groove 06 accordingly.

[0099] When the wind force increases to a critical value, the return force of the released spring will quickly drive the rotating shaft 33 and the mounting seat 31 to rotate and flip, and the display frame will be folded to a horizontal state.

[0100] When the display frame is turned over to the horizontal state, the linkage belt 41 changes from the original tightened state to the relaxed state.

[0101] The stop block 44 is disengaged from the surrounding meshing teeth 451 under the action of the spring sheet 442, and the third rotating arm 23 becomes rotatable.

[0102] Under the action of its own weight, the third rotating arm 23 rapidly rotates downward around the hinge to complete the descent, and at the same time, the loosened linkage belt 41 is tightened again.

[0103] The display frame moves down to a low stable state, and the third rotating arm 23 is locked again.

[0104] Finally, the display frame quickly dropped from a high horizontal state to a low vertical state, achieving rapid contraction.

[0105] A processing device for a part display frame mounting seat 31 in a rapid linkage shrinking mechanism adopts a linear transmission method so that the overall processing flow is convenient to form a fully automatic processing line by adding a loading and unloading mechanism.

[0106] The equipment includes:

[0107] 1. Workbench 100;

[0108] 2. Two groups of processing machines 200 with tools arranged in a straight line feeding from top to bottom, each group of processing machines 200 corresponds to processing the holes on one side of the display frame mounting seat, and one group of processing machines includes a drilling machine 210, a tapping machine 220 and a screw driving machine 230;

[0114] (4) A workpiece dynamic stabilization assembly 340, disposed between two sets of processing machines 200, is used to stabilize the transmission of the workpiece.

[0115] Linear transport track 300, see Figure 5 Its main working surface, i.e., the contact surface that mainly bears the weight of the display frame mounting seat 31, has an array of rollers 01; a track support plate 301 is provided on the side facing the processing machine tool, and the track support plate 301 is disconnected at the position section of the workpiece flipping assembly 330 and leaves a gap for the display frame mounting seat 31 to be taken out. At the same time, the track support plate 301 is also used to install the workpiece clamping assembly 320;

[0116] Display frame mounting seat 31, refer to Figure 7 As shown, it has flanges on both sides, and the flanges have holes 311 for positioning connected to the display frame. Generally, fastening bolts need to be installed in the holes, and the bolts are used to fix the display frame; refer to Figure 1-2 When the display frame mounting seat 31 is in assembly line processing, multiple display frame mounting seats 31 enter the conveying track 300 continuously and closely, and their flanges collide with the roller 01 to generate friction, so that the driving force of the forward driving component 310 can easily and smoothly push the display frame mounting seat 31.

[0117] Workpiece travel drive assembly 310, see Figure 4It is a cross slide structure composed of two telescopic cylinders, that is, it can move independently in the X-axis and Y-axis directions, wherein the telescopic end of the cylinder on the Y-axis has a vacuum suction cup, and the vacuum suction cup is used to temporarily adsorb the display frame mounting seat 31, so that the corresponding driving cylinder pushes the display frame mounting seat 31 to move intermittently in the X-axis direction, and the moving distance is alternately fed according to the spacing between the holes to be processed of two adjacent display frame mounting seats 31 and the spacing between the holes to be processed in a single display frame mounting seat 31, thereby cooperating with the workpiece turning component and the two groups of processing machines 200 to complete the processing successively until the display frame mounting seat 31 is output from the other end of the linear transmission track 300.

[0134] The rapid linkage retracting mechanism of this embodiment is applied to the wind-resistant protection of outdoor LED display screens.

[0135] The display screen body is mounted on a multi-section support arm with adjustable angles, and the end of the support arm is connected to the display screen through a quick linkage retraction mechanism. The structure of the retraction mechanism is basically the same as that of Example 1, and is mainly composed of a wind-adaptive flip actuator and a linkage descending mechanism.

[0136] When the display screen is working normally, the support arm lifts it to a high position, and the wind-adaptive flip actuator keeps the display screen upright. When the wind force increases, the wind force will flip the display screen to a horizontal folded state; at the same time, the linkage belt drives the support arm to drop rapidly, moving the display screen down to near the ground.

[0137] In this way, the display screen can avoid flipping and damage in strong wind conditions, and the rapid lowering of the height greatly reduces the wind load overturning moment, ensuring the safety of the equipment. At the same time, it can continue to play advertisements or prompt information in the folded state, ensuring business continuity.

[0138] This embodiment achieves intelligent wind-resistant protection for the display screen through a simple mechanical dynamic design, so that the device can adapt to a wider range of usage environments and improves the market applicability of the product.

[0139] Embodiment 3:

[0140] Application of rapid linkage retraction mechanism in solar tracking support system

[0141] The rapid linkage retraction mechanism of this embodiment is applied to a photovoltaic support system for solar power generation to achieve rapid retraction and flipping of hinged solar panels.

[0142] The solar panels are installed by lifting them with hinged support arms, which can rotate ±60° around the horizontal axis to track the position of the sun, thereby achieving higher power generation efficiency.

[0143] When strong winds come, the wind-adaptive flip actuator acts to cause the solar panel to translate and flip to a folded state parallel to the ground; at the same time, the linkage belt drives the support arm to rotate downward quickly, bringing the solar panel closer to the ground.

[0144] In this way, the solar panels can avoid being overturned, damaged or blown off in strong winds, and the wind load overturning moment is greatly reduced, ensuring the safety of the equipment. When the wind weakens, the solar panels can automatically return to the working state.

[0145] This embodiment increases the adaptability of the solar tracking system to severe weather, so that it can be applied to more places with harsh environmental conditions, improving the practicality of the device. At the same time, it also enhances the safety and reliability of the system.

[0146] Example 4: Rapid retraction of foldable carport

[0147] The retracting mechanism can be applied to a folding carport to achieve rapid folding and storage of the carport.

[0148] The carport roof is connected to the ground through a multi-section hinge bracket. Under normal conditions, the bracket lifts the roof for use. When encountering strong winds, the wind-adaptive flip mechanism drives the roof to flip to a vertical storage state; at the same time, the linkage mechanism drives the bracket to quickly retract, and the roof is stored close to the ground.

[0149] This can prevent the carport from being overturned and damaged by strong winds, ensuring the safety of the structure. It also enables the rapid storage of the carport.

[0150] Example 5: Quick storage of foldable caravan

[0151] The retracting mechanism is applied to a folding caravan to realize the rapid storage of the tarpaulin.

[0152] The roof tarpaulin is installed on the roof through a multi-section movable frame. Under normal conditions, the frame lifts the tarpaulin for use. When encountering strong winds, the flip mechanism drives the tarpaulin to fold; the linkage mechanism drives the frame to rotate downward quickly and put the tarpaulin into the car.

[0153] This can prevent the tarpaulin from being damaged by strong winds, ensuring the safety of the vehicle. It also enables the tarpaulin to be stored quickly and intelligently.
