Abstract

This invention discloses an automatic foam coating device for automotive hoses, aiming to solve the problems of low efficiency, poor coating quality, inaccurate positioning, and lack of reference for subsequent cable ties in existing manual operations. The device includes a support structure, an adhesive bonding mechanism, and a coating mechanism: the support structure precisely positions the transparent hose and its two end connectors at multiple points and presets the cable tie positions; the adhesive bonding mechanism automatically completes the sponge picking, adhesive backing paper peeling, and precise bonding through the coordinated action of vacuum suction cups and needle suction cups; the coating mechanism uses a C-shaped coating plate that reciprocates around the hose axis to achieve uniform and tight coating of the sponge. The entire process eliminates the need for manual film tearing, pasting, or pressing, significantly improving work efficiency and consistency. Simultaneously, the device integrates automatic waste collection, intelligent material supply, and cable tie positioning functions, making it suitable for automated production lines with high-speed, high-quality requirements, such as those in automotive manufacturing, effectively replacing traditional manual operations.

Description

Technical Field

[0001] This invention relates to the technical field of automotive parts manufacturing, specifically to an automatic protective sponge wrapping device for automotive hoses. Background Technology

[0002] In the assembly of automotive wiring harnesses or fluid lines, it is often necessary to wrap the outer perimeter of transparent flexible tubing with adhesive-backed protective foam to achieve functions such as cushioning, heat insulation, and noise reduction. Currently, this process is generally done manually: workers must manually peel off the protective paper from the back of the foam one by one, align and stick the foam to the designated position on the tubing, then press and wrap it with their fingers or simple tools, and finally tie it with cable ties with buckles at a specific workstation to secure the structure.

[0003] However, this manual method has significant drawbacks: First, manually tearing the film easily causes adhesive contamination, protective paper residue, or misalignment, resulting in low positioning accuracy and poor product consistency; second, relying on manual pressing makes it difficult to ensure the uniformity and tightness of the wrapping, often resulting in wrinkles, bubbles, gaps, or even detachment, affecting the protective performance; third, when multiple sponge segments need to be wrapped on the tube, the efficiency of repetitive operations is extremely low, severely restricting the production line cycle time and making it difficult to meet the needs of large-volume, high-efficiency production.

[0004] Therefore, there is an urgent need for an automated device that integrates automatic material handling, protective paper peeling, precise pasting, and mechanical wrapping to replace manual operation and significantly improve wrapping efficiency, quality stability, and overall assembly automation level. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic foam wrapping device for automotive hose protection, so as to solve the problems of low efficiency, unstable wrapping quality and poor positioning accuracy caused by relying on manual sponge pasting and wrapping in the prior art.

Multiple pieces of adhesive-backed sponges are neatly stacked inside the storage box. The dual-axis cylinders (first and second) work together to drive the vacuum suction cup to pick up one sponge from the storage box and peel off its protective adhesive paper. Subsequently, the telescopic cylinder drives the needle-type suction cup to pick up the sponge with the exposed adhesive surface and adhere it to the outer wall of the transparent tube. The covering mechanism, located below the pasting mechanism, includes a dual-axis cylinder three, a dual-axis cylinder four, a C-shaped covering plate, and a motor. The dual-axis cylinder three and the dual-axis cylinder four work together to coaxially sleeve the covering plate onto the outside of the pasted sponge. Subsequently, the motor drives the covering plate to reciprocate around the axis of the transparent tube, thereby tightly covering the outer circumference of the transparent tube with the sponge.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 10 As shown, this embodiment provides an automatic protective sponge covering device for automotive hoses, comprising: The support structure 10 is used to support and position the transparent hose 40. The support structure 10 includes a support platform 101. The upper side of the support platform 101 is provided with a plurality of support members and positioning members arranged at intervals along the axial direction of the transparent hose 40. This support structure can stably support and accurately position the transparent hose 40, avoid displacement or shaking during subsequent pasting and wrapping, provide a reliable benchmark for automated operation, and ensure that the sponge 50 is pasted accurately and wrapped evenly. The adhesive applicator 20, positioned above the support platform 101, includes a telescopic cylinder 204, a storage box 208, a dual-axis cylinder 211, a dual-axis cylinder 213, a vacuum suction cup 215, and a needle-type suction cup 217. Multiple pieces of adhesive-backed sponges 50 are neatly stacked inside the storage box 208. The dual-axis cylinders 211 and 213 work together to drive the vacuum suction cup 215 to pick up a piece of sponge 60 from the storage box 208 and peel off its adhesive backing paper 60. Subsequently, the telescopic cylinder 204 drives the needle suction cup 217 to adsorb the exposed adhesive surface of the sponge 50 and attach the sponge 50 to the outer wall of the transparent tube 40. Through the step-by-step coordinated action of the vacuum suction cup 215 and the needle suction cup 217, the entire process from picking up the sponge 50, automatically peeling off the adhesive backing paper 60 to pasting the adhesive surface is fully automated, completely replacing manual film tearing and pasting operations, significantly improving pasting efficiency and consistency, and avoiding problems such as adhesive surface contamination and misalignment caused by human operation.

[0029] The covering mechanism 30, located below the pasting mechanism 20, includes a dual-axis cylinder 303, a dual-axis cylinder 305, a C-shaped covering plate 307, and a motor 310. The dual-axis cylinders 303 and 305 work together to coaxially sleeve the covering plate 307 onto the outside of the pasted sponge 50. Subsequently, the motor 310 drives the covering plate 307 to reciprocate around the axis of the transparent flexible tube 40, thereby tightly covering the sponge 50 onto the outer circumference of the transparent flexible tube 40. The C-shaped covering plate 307 applies circumferential pressure to the sponge 50 through reciprocating deflection, ensuring it adheres tightly to the curved surface of the transparent flexible tube 40, eliminating wrinkles and gaps, and ensuring a firm covering and a smooth appearance. This mechanical covering method is more uniform and efficient than manual pressing, and is particularly suitable for mass production scenarios where high covering quality stability is required.

[0030] In this embodiment, nozzles 41 and quick connectors 42 are respectively connected to both ends of the transparent flexible tube 40; the support member is a support block 102, and the upper side of the support block 102 is provided with a support groove 102a that matches the outer contour of the transparent flexible tube 40; the positioning member includes a positioning block 103 and a positioning block 2 104, the upper side of the positioning block 103 is provided with a positioning groove 103a that matches the shape of the nozzle 41, and the upper side of the positioning block 2 104 is provided with a positioning groove 2 104a that matches the shape of the quick connector 42. Special positioning grooves are designed for the irregular structures at both ends of the transparent flexible tube 40 (nozzle 41 and quick connector 42) to achieve quick and precise clamping of the entire transparent flexible tube 40, preventing deviation in the adhesive position of the sponge 50 due to end suspension or misalignment.

[0031] Furthermore, the positioning component also includes multiple positioning blocks 105 spaced apart along the axial direction of the transparent flexible tube 40, each positioning block 105 having a positioning groove 105a on its upper side. The position of the positioning groove 105a corresponds to the designated work position where the cable ties with buckles need to be tied later. After the sponge covering process is completed, operators or automated equipment can quickly and accurately tie the cable ties with buckles to the predetermined position of the transparent flexible tube 40 according to the positioning groove, ensuring assembly consistency and work efficiency.

[0032] In this embodiment, the pasting mechanism 20 further includes a rodless cylinder 201, which is horizontally mounted above the support platform 101 via a pair of support plates 202. Its slider is connected to a transverse plate 203. A telescopic cylinder 204 is vertically mounted on the transverse plate 203, and its piston rod is connected downward to a U-shaped connecting frame 205. The storage box 208 is fixed to both ends of the connecting frame 205, and its bottom is provided with an X-shaped suction port 208a. A dual-axis cylinder 211 is vertically mounted on the rear side of the storage box 208, and its piston rod is connected downward to a lifting plate 212. A dual-axis cylinder 213 is horizontally mounted on the lower side of the lifting plate 212, and its piston rod is connected forward to a moving plate 214. A pair of vacuum suction cups 215 are symmetrically mounted on the moving plate 214, and a pair of needle suction cups 217 are symmetrically mounted on the front side of the storage box 208 via a fixing plate 216. The entire pasting mechanism 20 is driven by a rodless cylinder 201 to move precisely along the axis of the transparent tube 40, and can automatically complete the pasting of the sponge 50 at multiple preset positions in sequence. Upon reaching the target position, the piston rods of dual-axis cylinder 213 and dual-axis cylinder 211 retract sequentially, driving the vacuum suction cup 215 through the suction port 208a at the bottom of the storage box 208 to adsorb the adhesive protective paper 60 on the back of the bottom layer of sponge 50. Then, the piston rods of dual-axis cylinder 211 and dual-axis cylinder 213 extend sequentially, moving the adsorbed sponge 50 directly below the needle suction cup 217. Next, the needle suction cup 217 adsorbs the sponge 50 body. Then, the piston rods of dual-axis cylinder 213 and dual-axis cylinder 211 retract sequentially, causing the vacuum suction cup 215 to peel off the adhesive protective paper 60, completing the automatic film removal. Finally, the piston rod of the telescopic cylinder 204 extends, precisely attaching the sponge 50 with exposed adhesive to the outer wall of the transparent tube 40, achieving non-destructive, high-precision adhesion. This multi-stage coordinated action process completely replaces manual film removal and attachment operations, significantly improving work efficiency, consistency, and reliability.

[0033] In this embodiment, the covering mechanism 30 further includes a rodless cylinder 301, which is horizontally mounted on the upper side of the support platform 101. Its slider is connected to a Z-shaped transverse plate 302. A dual-axis cylinder 303 is horizontally mounted on the upper side of the transverse plate 302, and its piston rod is connected forward to a moving plate 304. A dual-axis cylinder 305 is vertically mounted on the front side of the moving plate 304, and its piston rod is connected downward to a T-shaped lifting plate 306. The lower side of the lifting plate 306 is provided with a U-shaped receiving groove 306a, and the covering plate 307 is movably connected within the receiving groove 306a. By driving the entire covering mechanism 30 precisely along the axial direction of the transparent tubing 40 with the rodless cylinder 301, the covering operation of the sponge 50 can be automatically completed sequentially at multiple preset positions. Upon reaching the target position, the piston rods of dual-axis cylinders 303 and 305 extend sequentially, causing the C-shaped covering plate 307 and the transparent hose 40 to be coaxially distributed and closely attached to the upper side of the sponge 50. This multi-degree-of-freedom collaborative positioning ensures that the initial posture of the covering is accurate and consistent, laying the foundation for the subsequent reciprocating deflection of the covering plate 307 by the motor 310 to achieve uniform and tight covering, effectively avoiding eccentricity or interference, and improving the covering quality and equipment operation stability.

[0034] In this embodiment, the covering plate 307 has an arc-shaped connecting strip 308 in the middle, and external gear rings 309 with notches are symmetrically connected to both sides of the connecting strip 308. The left and right sides of the lifting plate 306 are respectively equipped with motors 310 through fixing shells 311. Gear 312 is installed on the output shaft of each motor 310. A pair of connecting shafts 313 are rotatably connected to both sides of the receiving groove 306a. Gear 314 is symmetrically provided in the middle of each connecting shaft 313. Both gear 312 and gear 314 mesh with the external gear rings 309. After the left and right motors 310 are evenly driven by the corresponding gear 312 and external gear 309, they stably drive the C-shaped covering plate 307 to reciprocate around the axis of the transparent tube 40, thereby uniformly, flatly and wrinkle-free covering of the adhesive-backed sponge 50 on the outer circumference of the transparent tube 40, significantly improving the covering quality and consistency.

[0035] Furthermore, the support platform 101 is provided with a through groove 101a, and a trash can is arranged below the through groove 101a. After the adhesive protective paper 60 is peeled off, it can fall directly into the trash can through the through groove 101a, realizing automatic waste collection, keeping the work area clean, reducing the frequency of manual cleaning, and improving the continuous operation capability of the production line.

[0036] Furthermore, guide posts 206 are symmetrically arranged on the left and right sides of the connecting frame 205. Each guide post 206 extends upward and slides in cooperation with the transverse plate 203 through a guide sleeve 207. The guide posts 206 and the guide sleeves 207 form a guide pair, which effectively suppresses the shaking and deflection of the connecting frame 205 during the lifting process, ensures the smooth movement of the storage box 208 and the adsorption assembly, and improves the positioning accuracy of material picking and pasting.

[0037] Furthermore, the storage box 208 has a U-shaped stacking opening 208b on its front side. The U-shaped stacking opening 208b facilitates the operator to quickly replenish the sponge sheet 50, and at the same time allows direct observation of the remaining amount of sponge 50 in the storage box 208, facilitating timely replenishment.

[0038] Furthermore, the storage box 208 is equipped with an X-shaped pressure plate 209 inside, and a screw 210 is connected to the center of the pressure plate 209. The pressure plate 209 applies a constant downward pressure to the sponges 50 stacked inside the storage box 208, effectively preventing material retrieval failures or the accidental retrieval of multiple sponges due to loose stacking of the sponges 50, ensuring that only the bottommost sponge 50 is retrieved each time, thus guaranteeing stable material supply. Simultaneously, this downward pressure makes the sponges 50 more compactly arranged, increasing the loading capacity of the storage box 208 and reducing the frequency of manual replenishment. In addition, the screw 210 also serves as a handle, making it easy for operators to lift the pressure plate 209 for quick sponge replenishment.

[0039] The working principle of an automatic protective sponge covering device for automotive hoses is as follows: S1. Place the transparent hose 40 with nozzles 41 and quick connectors 42 at both ends on the support structure 10. Its body is supported by the support block 102, and its ends are precisely positioned by positioning block one 103 and positioning block two 104. The position of the middle cable tie is preset by multiple positioning blocks three 105. S2. Rodless cylinder 201 drives the pasting mechanism 20 to move axially along the transparent tube 40 to the first pasting station; dual-axis cylinder 213 works in coordination with dual-axis cylinder 211 to make the vacuum suction cup 215 pass through the suction port 208a at the bottom of the storage box 208 and adsorb the adhesive protective paper 60 on the back of the bottom layer of sponge 50; then it is moved to the bottom of the needle suction cup 217, where the needle suction cup 217 adsorbs the sponge 50 body; then the vacuum suction cup 215 peels off the adhesive protective paper 60; finally, the telescopic cylinder 204 descends to paste the sponge 50 to the outer wall of the transparent tube 40; S3. Rodless cylinder 2 301 drives the covering mechanism 30 to move to the corresponding work position; dual-axis cylinder 303 and dual-axis cylinder 4 305 actuate to make the C-shaped covering plate 307 coaxially sleeved on the outside of the pasted sponge 50; motor 310 starts, and through gear 1 312, gear 2 314 meshing with the external gear ring 309, drives the covering plate 307 to reciprocate around the axis of the transparent tube 40, so as to tightly and flatly cover the sponge 50 on the outer periphery of the transparent tube 40; S4. The peeled backing protective paper 60 falls into the trash can below through the through groove 101a on the support platform 101; S5. Repeat S2-S3 to complete the pasting and covering of multiple locations in sequence; S6. After the wrapping is completed, the operator or automated equipment quickly and accurately binds the cable ties with buckles at the designated position according to the positioning slot 3105a to ensure assembly consistency.

[0040] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
