Description

Technical Field

[0001] The present invention belongs to the technical field of production of embedded blinds in air duct systems, and in particular relates to a controllable flexible assembly mechanism and its application in production of embedded blinds in air ducts. Background Art

[0002] Duct embedded shutters are one of the key components of the duct system. Most of them are made of thin-walled aluminum alloy. Figure 1 and Figure 2 As shown, it includes a rectangular frame composed of a transverse frame beam 9 and a longitudinal frame beam 8, a plurality of shutters are installed on the rectangular frame, and mounting holes are provided on both the transverse frame beam 9 and the longitudinal frame beam 8. The mounting holes on the longitudinal frame beam 8 are used to insert the shutters, and the mounting holes on the transverse frame beam 9 are used to insert the support ribs 7. The shutter includes a shaft 5, a blade is provided on the shaft 5, and a notch 6 is provided on the blade, and the notch 6 is used to insert the support ribs 7.

[0003] In the production process of duct-embedded blinds, manual assembly is currently the main method, and the main steps are: first weld the blind frame, then insert the blind support ribs, and then clip the blinds one by one on the support ribs and the blind frame. Among them, two operators are required to cooperate in the clipping of the blinds, one of whom first clips the blind shaft into the notch of the support rib, and then pushes the blind forward along the notch. When the blind shaft is about to reach the blind frame, the two operators insert the blind shaft ends into the corresponding mounting holes on the blind frame, and then flip the blind. However, as mentioned above, the existing operating method has many disadvantages: the assembly efficiency of the duct embedded blinds is low, and the assembly of a single duct embedded blinds with 88 blinds takes about forty minutes, of which the insertion of a single blind takes 18 to 25 seconds; since the inner wall width of the frame of the duct embedded blinds is 8 to 15 mm longer than the axis of the blinds, the blinds will inevitably bend flexibly during the assembly process, and the proportion of flexible bending of the blinds is as high as 100%. After the duct embedded blinds are assembled, they need to be corrected, which is troublesome; in the process of operating the blinds' shaft to fit into the notch of the support ribs, since the shaft needs to be inserted into the notches of multiple support ribs one after another, it is easy to cause the blinds and the support ribs to get stuck. In this case, the only way to continue is to adjust the insertion posture and angle of the blinds. Summary of the invention

[0004] At least in view of the problems mentioned in the background technology, one of the purposes of the present invention is to provide a controllable flexible assembly mechanism and its application in the production of duct-embedded blinds. The flexibility in the present invention should be understood as adjustable and programmable control, specifically, it means that the power system of the deflection limit assembly can be controlled by a program, thereby driving the connecting rod and the baffle to perform corresponding actions, and the blinds of the duct-embedded blinds can be adjusted and limited during the assembly process with the help of the deflection limit assembly, the sliding assembly and the wiring harness.

[0005] The present invention adopts the following technical solution.

[0007] In order to assemble the workpiece more stably and quickly, the sliding assembly includes a slide rail and a slide rod matched on the slide rail, and a plurality of arc-shaped limit grooves arranged in parallel are provided on the slide rod.

[0008] Furthermore, the deflection limiting assembly includes a power system, and a connecting rod is provided at the output end of the power system, and the connecting rod is fixedly connected to the baffle.

[0010] Preferably, the wiring harness uses a PE wire with a diameter not greater than 2 mm.

[0011] Preferably, the main structure of the sliding rod is cylindrical.

[0013] Furthermore, the application of the aforementioned controllable flexible assembly mechanism in the production of duct embedded blinds comprises the following steps:

[0014] Step 1: Adjust the distance between the two slide bars so that the axis of the blind can be placed on the two slide bars at the same time;

[0015] Step 2, firstly placing a plurality of shutters on the sliding rod at one time, and then controlling the power system of the deflection limit assembly to operate so that both baffles are in a state perpendicular to the sliding direction;

[0016] Step 3, spreading the louvers in a direction perpendicular to the sliding direction, so that the axes of all louvers are respectively inserted into the corresponding arc-shaped limiting grooves;

[0017] Step 4: Pull the wire harness and straighten it. The wire harness will be inserted into the gaps of all the blinds.

[0018] Step 5: Install the blinds' support ribs along the wiring harness, and then pull out the wiring harness;

[0019] Step 6, first insert the longitudinal frame beams at both ends of the shaft, then insert the transverse frame beams of the blinds, and then weld the frame beams to fix them;

[0020] Step 7, control the deflection limit assembly to reset and remove the blinds.

[0021] Preferably, in step 2, the number of louvers is not more than (not greater than) the number of arc-shaped limiting grooves on a single sliding rod.

[0022] Preferably, the depth of the arc-shaped limiting groove is equal to the diameter of the shaft.

[0023] Beneficial effect: The technical solution of the present invention not only fundamentally solves the problem of flexible bending of the blinds during the assembly / assembly of the duct embedded blinds, eliminating the tedious process of correction after the duct embedded blinds are assembled, but also significantly improves the assembly / assembly efficiency of the duct embedded blinds (taking the assembly of a single duct embedded blinds with 88 blinds as an example, it only takes less than ten minutes, of which all the blinds can be installed in less than three minutes), and can also effectively prevent the blinds from getting stuck with the supporting ribs.

[0034] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0035] Combination Figures 3 to 10 As shown, a controllable flexible assembly mechanism includes two sets of sliding components 1 arranged in parallel and capable of adjusting the spacing toward each other, two sets of deflection limit components 2 are arranged on the outside of the sliding components 1, and the deflection limit components 2 in the limited state are perpendicular to the sliding direction of the sliding components 1; a wire harness 3 that can be straightened and stored is arranged on the inside of the two sets of sliding components 1, and the straightened wire harness 3 is perpendicular to the sliding direction. Among them, the sliding assembly 1 includes a sliding rail 10 and a sliding rod 11 matched on the sliding rail 10. The main structure of the sliding rod 11 is cylindrical. A plurality of arc-shaped limit grooves 12 arranged in parallel are arranged on the sliding rod 11. The depth of the arc-shaped limit grooves 12 is equal to the diameter of the shaft 5, and the spacing between adjacent arc-shaped limit grooves 12 is just equal to the spacing between adjacent blinds of the duct embedded blinds; the deflection limit assembly 2 includes a power system 22 (specifically a motor), and a vertically arranged connecting rod 20 is arranged at the output end of the power system 22. The connecting rod 20 is fixedly connected to the transversely arranged baffle 21. When the power system 22 is in operation, it drives the connecting rod 20 to rotate, thereby driving the baffle 21 to deflect.

[0036] In this embodiment, the stretched wire harness 3 is lower than the top surface of the slide bar 11, and the wire harness 3 uses a PE wire with a diameter not greater than 2 mm. An adjustment mechanism 15 is provided outside the slide bar 11, and the adjustment mechanism 15 can be operated by a hand wheel. The adjustment mechanism 15 is used to adjust the position of the slide bar 11. Fig.10As shown, a metal ring 16 is provided at the end of the wiring harness 3, and the head end of the wiring harness 3 is fixed on the column. A wiring harness fixing frame 17 is provided on the opposite side of the column. A card slot 18 is provided on the wiring harness fixing frame 17. The width of the card slot 18 is smaller than the diameter of the metal ring 16. When in use, the wiring harness 3 can be limited by the metal ring 16 after being inserted into the card slot 18. At this time, the metal ring 16 just presses against the side wall of the wiring harness fixing frame 17.

[0037] In this embodiment, the deflection limit assembly 2, the sliding assembly 1, the adjustment mechanism 15, and the column are all installed on the bracket 4, and the height of the space inside the bracket 4 and between the two sets of sliding assemblies 1 is set to one meter. Example 2

[0038] An application of the controllable flexible assembly mechanism in embodiment 1 in the production of duct embedded blinds, combined with Figures 1 to 10 As shown, the steps include:

[0039] Step 1, adjusting the distance between the two slide bars 11 so that the shaft 5 of the shutter can be placed on the two slide bars 11 at the same time, wherein the number of the shutters is not more than the number of the arc-shaped limiting grooves 12 on a single slide bar 11;

[0040] Step 2, first place multiple louvers on the slide bar 11 at one time, and then control the power system of the deflection limit assembly 2 to operate so that both baffles 21 are in a state perpendicular to the sliding direction; the purpose of this step is to quickly adjust the ends of all louvers to be in the same vertical plane;

[0041] Step 3, spread the shutters in a direction perpendicular to the sliding direction, so that the shafts 5 of all shutters are respectively inserted into the corresponding arc-shaped limit grooves 12. The state at this time is as follows: Figure 6 As shown; since the blades of the louver are connected to the shaft 5, as long as the two ends of the shaft 5 are placed in the arc-shaped limiting grooves 12, the blades of the louver will flip to a drooping posture, thereby ensuring that the notches 6 on the blades of the louver face downward; therefore, the main function of this step is to quickly put all the louvers in place at one time (essentially different from the existing solution of inserting the louvers one by one), and automatically adjust the posture of the louver, so as to facilitate the subsequent insertion of the wiring harness 3 and the supporting ribs 7 into the notches 6 of the louver;

[0042] Step 4: Pull the wire harness 3 and straighten it. The wire harness 3 will be inserted into the gaps 6 of all the blinds. Figure 7 and Figure 8 As shown; this step is very critical, and its main function is to guide the support rib 7 to quickly and smoothly fit into the notch 6, and the straightened wire harness 3 can also support and adjust the relative positions of different louver notches 6;

[0043] Step 5, follow the harness 3 to clamp the support rib 7 of the blinds, and then pull out the harness 3. The state at this time is as follows: Fig. 9 As shown;

[0044] Step 6, first insert the longitudinal frame beams 8 at both ends of the shaft 5, then insert the transverse frame beams 9 of the blinds, and then weld the frame beams to fix them;

[0045] Step 7, control the deflection limit assembly 2 to reset and remove the blinds.

[0046] In this application scheme, through the coordination of a specific controllable flexible assembly mechanism and each step, it is possible to eliminate the need to bend the blinds before inserting them during the assembly / assembly process of the duct embedded blinds. Instead, the frame beam is inserted from the end of the shaft 5 (this technical route is essentially different from the existing scheme); on the other hand, since a straight wire harness 3 is used to insert into the notches 6 of all blinds, the blinds are cleverly supported by the wire harness 3, thereby guiding the support ribs 7 to quickly and smoothly insert into the notches 6, and facilitating the removal of the wire harness 3 from the notches 6.

[0047] The solution of the embodiment not only fundamentally solves the problem of flexible bending of the blinds during the assembly / assembly of the duct embedded blinds, eliminating the tedious process of correction after the duct embedded blinds are assembled, but also significantly improves the assembly / assembly efficiency of the duct embedded blinds (taking the assembly of a single duct embedded blinds with 88 blinds as an example, it only takes less than ten minutes, of which all the blinds can be installed in less than three minutes), and can also effectively prevent the blinds from getting stuck with the supporting ribs.
