Description

Technical Field

[0001] The present application relates to the field of automatic grille production, and in particular to a wire laying device for grille production with an anti-wire-stripping component. Background Art

[0002] In the field of industrial production, composite grille products are widely used in many fields due to their unique advantages. With the continuous advancement of science and technology, its production technology is also constantly developing. Existing composite grille production equipment mainly optimizes the production process through automation technology. For example, the fully automated production line of molded grilles can realize the automation of all processes in the production cycle of molded grilles, shorten the process interval, improve product production efficiency, and facilitate the large-scale production of molded grilles. The production line adopts a new weaving device and injection molding device, which makes the fiber weaving more reasonable, reduces the repetition rate, and accurately quantifies the resin injection, which improves the resource utilization rate and the overall quality of molded grille products.

[0003] However, although these automation technologies have improved production efficiency and product quality to a certain extent, some problems are still exposed in practical applications. In the production process, fiber placement and compaction are key steps, but the automation and accuracy of existing equipment in these two links still need to be improved. Especially when the wire is laid to the outer corner, the change in the laying direction is prone to wire shedding. This wire shedding phenomenon not only affects the completion of the automated production of the product, but may also cause the mechanical properties of the product to deteriorate, affecting its stability and reliability in practical applications. Summary of the invention

[0004] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a wire laying device for grille production with an anti-wire-stripping component.

[0005] To achieve the above-mentioned purpose, the present application discloses a wire laying device for grille production with an anti-wire-stripping function, the wire laying device comprising a supporting base, a rotating wire laying mechanism and a rotating drive unit.

[0006] Among them, the supporting base is a rigid support frame, and the rotating wire laying mechanism is rotatably installed in the middle of the supporting base through a slewing support assembly, and the angle adjustment around the horizontal axis is realized through a rotating drive unit; a wire pressing assembly corresponding to the motion trajectory of the rotating wire laying mechanism is provided on the supporting base, and the assembly includes a main wire pressing mechanism arranged along the same linear direction and auxiliary wire pressing mechanisms symmetrically distributed on both sides thereof, and each mechanism independently realizes axial telescopic movement through a linear drive module.

[0007] The rotary wire routing mechanism is provided with a plurality of wire guide channels which are equidistantly distributed along a horizontal axis, and a directional guiding structure is formed at the end of each wire guide channel.

[0008] The main wire pressing mechanism comprises an elastic pressing unit, a linear transmission device and a pressing actuator, wherein the pressing actuator realizes linear displacement in a vertical direction through the linear transmission device.

[0009] The pressing actuator is located at the periphery or one side of the outer wire guide channel. At the same time, a bundling groove extending and opening along the distribution direction of the wire guide channel is opened on one side of the pressing actuator to gather and constrain the wire arrangement trajectory.

[0010] The bottom of the pressing actuator is provided with a guiding structure extending downward and used to guide the wire, and the guiding structure includes two guiding rods or blocks arranged with the opening of the clustering groove as the center. The bottom surface of the pressing actuator under the guiding rod cooperates to form a guiding channel, the axis of which is consistent with the arrangement direction of the clustering groove, and cooperates with the original wire guide channel to complete the directional guidance of the wire during the pressing operation.

[0011] Furthermore, the guide structure is detachably mounted on the bottom of the pressing actuator.

[0012] Furthermore, the opening of the clustering groove in the pressing actuator is a V-shaped gradual structure.

[0013] Furthermore, the elastic top pressure unit includes a pre-tensioning spring, the two ends of which are respectively connected to the top of the pressing actuator and the output end of the linear transmission device, providing elastic pre-tensioning force when the pressing actuator moves downward to prevent excessive downward pressure on the pressing actuator and reduce the impact load at the moment of contact with the mold cavity.

[0014] Furthermore, the symmetry axis of the auxiliary wire pressing mechanism is arranged orthogonally to the arrangement direction of the wire guide channel, and its downward pressing actuator adopts a sheet structure. The two sets of auxiliary wire pressing mechanisms are driven by independent control units, and abut against the surface of the mold cavity in stages during the turning process to form a relay pressing area with the main wire pressing mechanism to ensure the continuity constraint at the turning point of the wire.

[0028] Refer to the attached Figures 1 to 6 This embodiment relates to a wire laying device for grille production with a wire-stripping prevention function, which is mainly composed of a bearing base 1, a rotating wire laying mechanism 2 and a rotating driving unit 3. The bearing base 1 serves as a rigid support frame for the entire device.

[0029] The rotary wire-laying mechanism 2 is rotatably mounted on the bottom of the bearing base 1 through a slewing support assembly. The slewing support assembly includes a mounting seat with an inner ring fixed to the rotary wire-laying mechanism 2, a high-precision ball bearing with an outer ring connected to the bearing base 1, and a high-temperature resistant rubber sealing ring for sealing grease, so as to ensure that the rotary wire-laying mechanism 2 can stably and accurately adjust the angle around the horizontal axis. The rotary drive unit 3 uses a combination of a servo motor and a reducer. The servo motor is installed on one side of the bearing base 1, and its output shaft is connected to the reducer through a coupling. The output end of the reducer is then connected to the inner ring of the slewing support assembly of the rotary wire-laying mechanism 2. The precise positioning and smooth rotation of the rotary wire-laying mechanism 2 are achieved through precise motor control.

[0030] The bearing base 1 is provided with a wire pressing assembly that precisely corresponds to the motion trajectory of the rotating wire laying mechanism 2. The assembly includes a main wire pressing mechanism 4 arranged along the same straight line direction and auxiliary wire pressing mechanisms 5 symmetrically distributed on both sides thereof. Each mechanism independently realizes axial telescopic movement through a linear drive module. The linear drive module adopts a screw-nut transmission structure. One end of the screw is fixed to the bearing base 1, and the other end is supported by a bearing seat. The nut is connected to the mounting seat of the wire pressing mechanism, and cooperates with a high-precision ball screw to ensure the straightness and stability of the wire pressing mechanism in the axial telescopic movement. The main wire pressing mechanism 4 includes an elastic top pressing unit, a linear transmission device and a pressing actuator 6, wherein the pressing actuator 6 realizes linear displacement in the vertical direction through a linear transmission device. The elastic top pressure unit adopts a pre-tensioning spring, and the two ends of the pre-tensioning spring are respectively connected to the top of the pressing actuator 6 and the output end of the linear transmission device. During the downward process of the pressing actuator 6, the pre-tensioning spring can provide a stable elastic pre-tensioning force, effectively preventing the pressing actuator 6 from causing damage to the wire and the mold due to excessive downward pressure, while reducing the impact load generated when contacting the mold cavity, thereby extending the service life of the equipment.

[0031] According to the needs, during implementation, the pressing actuator 6 is made of hard alloy material with high hardness and high wear resistance. It is located at the periphery or one side of the outer guide wire channel, and one side is provided with a cluster groove 7 extending along the distribution direction of the guide wire channel and being open. According to needs, the opening of the clustering groove 7 can be V-shaped and gradually changed (this structure is not shown in the attached drawings of this embodiment). The surface of the groove wall is finely polished and smooth without burrs, which can effectively gather and constrain the wire arrangement trajectory, so that the wires are closely arranged when passing through to avoid looseness, thereby improving the weaving density and overall strength of the grid product. The axis of symmetry of the auxiliary wire pressing mechanism 5 is arranged orthogonally to the arrangement direction of the wire guide channel. Its downward pressing actuator adopts a sheet structure, which is stamped and formed by a stainless steel sheet and has good toughness and deformation resistance. The two sets of auxiliary wire pressing mechanisms 5 are driven by independent control units, and abut against the mold cavity surface in stages during the turning process, forming a relay pressing area with the clustering groove 7 of the main wire pressing mechanism 4, ensuring that the wires are always subject to continuous and stable restraining force at the turning point, avoiding the wires from being detached or scattered during the turning process, and ensuring the continuity and stability of the grid weaving.

[0032] Based on the above structure, refer to the attached Figure 5 and 6 The key structure of the pressing actuator 6 includes a guide structure at the bottom. The guide structure is centered on the opening of the cluster groove and is provided with two guide blocks 8. The two guide blocks 8 extend downward from the bottom of the pressing actuator and cooperate with the bottom surface of the pressing actuator to form a guide channel 9. The axis of the guide channel 9 is consistent with the arrangement direction of the cluster groove, so that it replaces the original wire guide channel during the pressing operation to complete the directional guidance of the wire.

[0033] The two guide blocks 8 are symmetrically distributed on both sides of the clustering slot opening, and the distance between them is precisely set according to the diameter of the wire and the process requirements to ensure that the wire can smoothly pass through the guide channel 9 .

[0034] Refer to the attached Figure 7 There is another form of the guiding structure, in which a guiding rod 10 is used. The guiding rod 10 and the guiding block 8 are only different in form, but have the same function, effect and purpose. Therefore, the specific functions refer to the guiding block 8 and will not be described in detail.

[0035] Furthermore, the guide structure is detachably mounted at the bottom of the pressing actuator. The specific implementation method is to set a threaded connection structure between the guide block 8 and the bottom of the pressing actuator. The guide block 8 is provided with a threaded hole, which cooperates with the stud at the bottom of the pressing actuator and is fastened by a nut. This detachable design facilitates the quick replacement of the guide block 8 or adjustment of the position of the guide block 8 when necessary to adapt to wires of different specifications or process requirements.

[0036] In actual application, when the pressing actuator is pressed down, the guide block 8 and the guide groove 9 formed by the bottom surface of the pressing actuator can accurately guide the wire to move in a predetermined direction, ensuring the position accuracy and stability of the wire during the pressing process. At the same time, due to the detachable nature of the guide structure, maintenance personnel can easily inspect, maintain or replace the guide block 8, which improves the flexibility and maintenance efficiency of the equipment.

[0037] In the actual production process, when the grid production line is started, the rotating wire laying mechanism 2, driven by the rotating drive unit 3, adjusts the angle around the horizontal axis according to the preset process parameters, so that each wire guide channel can accurately guide the wire to the specified position. At the same time, the main wire pressing mechanism 4 and the auxiliary wire pressing mechanism 5 in the wire pressing assembly independently control the axial telescopic movement through the linear drive module according to the weaving process. The pressing actuator 6 of the main wire pressing mechanism 4 stably presses and constrains the wire under the preload force of the elastic top pressure unit. The clustering groove 7 and the guide channel 9 effectively gather the wires so that they are closely arranged and enter the mold cavity. At the turning stage of the wire, the auxiliary wire pressing mechanism 5 abuts against the surface of the mold cavity in stages, and relays the main wire pressing mechanism 4 to constrain the wire, ensuring the continuity and stability of the turning point of the wire, effectively preventing the occurrence of wire shedding, and improving the quality and production efficiency of the grid products.

[0038] In particular, the wire laying device can make the wire guide channel perform corresponding rotational adjustments in the vertical direction through the horizontal rotation of the rotating wire laying mechanism 2, thereby changing the wire outlet angle of the wire. This angle adjustment helps to reduce the stress concentration at the wire outlet and prevent the wire from being broken due to excessive stress during the wire outlet process. Specifically, when the rotating wire laying mechanism 2 rotates around the horizontal axis, the vertical position of the wire guide channel changes accordingly, so that the angle of the wire when it is led out from the wire guide channel changes. By reasonably controlling the rotation angle of the rotating wire laying mechanism 2, the wire outlet angle of the wire can be optimized, so that the wire is more evenly stressed during the lead-out process, avoiding the problem of wire breakage caused by excessive local stress, and further improving the stability of the production process and the quality of the product.

[0039] In the case of laying multiple wire bundles at the same time, when an angle shift is required, the rotating wire laying mechanism 2 is first rotated so that the wires of multiple wire guide channels are pressed and guided together by the pressing actuator 6. The pressing actuator 6 gathers the wires from the side through its bunching groove 7 and guide groove 9 and guides them to the bottom surface together, while the auxiliary wire pressing mechanism 5 presses the wire bundles on the side according to the direction of the angle to ensure the continuity and stability of the wires at the turning point. For example, when the wires need to turn from the side to the bottom surface, the bunching groove 7 of the pressing actuator 6 first gathers the wires and guides them to the bottom surface, and then the auxiliary wire pressing mechanism 5 presses the wire bundles on the side according to the direction of the angle to prevent the wires from becoming loose or falling off during the turning process, thereby ensuring the continuity and stability of the grid weaving.

[0040] It should be noted that the specific selection and installation methods of the servo motor, reducer, ball screw and other components used in this embodiment, as well as the assembly process of the high-precision ball bearing of the slewing support assembly, are all well-known technologies and existing technologies for those skilled in the art, and will not be described in detail here. In addition, the electrical control parts such as the control circuit of the linear drive module and the drive circuit of the servo motor are also conventional technical means in this field and are not described in detail in this embodiment.

[0041] Compared with the traditional wire laying device, the wire laying device in the embodiment of the present invention shows significant advantages in actual production scenarios. In a comparative test conducted by a grille production enterprise, the grille products produced using the device of the present invention have significantly improved the neatness of the wire arrangement, greatly reduced the damage to the mold cavity caused by impact, and significantly improved the wire laying efficiency, effectively reducing production costs and improving production efficiency, which fully proves the practicality and superiority of the device in the field of grille production.

[0042] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims.
