A fully automated assembly mechanism for multiple components of automotive interior carpets

Abstract

This invention discloses a fully automated assembly mechanism for multiple components of automotive interior carpets, including a base. A lower mold and an upper mold are sequentially arranged on the base, forming a molding space for processing carpet raw materials. The mechanism also includes: multiple positioning platforms symmetrically arranged around the base; positioning rods movably mounted on the positioning platforms and capable of displacement along the X-axis and Y-axis via a guide assembly. The guide assembly provides resistance to prevent the positioning rods from approaching the molding space. The edges of the carpet raw materials have through holes that match the positioning rods. This invention uses positioning rods, with the carpet raw material positioned by the through holes at its edges. During mold closing, the carpet raw material retracts into the molding space, and the guide rods move closer to the molding space under the influence of the carpet raw material. However, because the movement of the positioning rods is restricted by the positioning platforms to outside the molding space, the edges of the carpet raw material are prevented from retracting into the molding space.

Description

Technical Field

[0001] This invention relates to the field of automotive carpet technology, and more specifically to a fully automated assembly mechanism for multiple components of automotive interior carpets. Background Technology

[0002] Automotive carpet assembly refers to the process of assembling automotive carpets according to specified technical requirements and then adjusting and inspecting them to make them qualified products. Among them, some plastic parts, sound-absorbing cotton, and shock-absorbing felts on automotive carpets can be assembled simultaneously during the carpet molding process. Specifically, by pre-setting the positions in the carpet molding mold and applying glue to the accessories, each pre-set component can automatically adhere to the carpet and complete the assembly when the carpet is pressed to fit the inner wall of the mold cavity.

[0003] Patent document CN105856477A, ​​published on August 17, 2016, discloses a cold-forming mold for automotive carpets. The technical solution includes: an upper mold base, an upper mold, a lower mold, a lower mold base, and a pressing device. The pressing device is a pressing arm hinged to the lower mold. A torsion spring is mounted on the hinge shaft of the pressing arm, and the two torsion arms of the torsion spring respectively abut against the outer wall of the lower mold and the pressing arm. The lower mold has a cavity, and at least two movable support frames are symmetrically arranged on both sides of the cavity on the lower mold. The lower mold has receiving holes that slide with the movable support frames, and springs connected to the movable support frames are installed inside the receiving holes. The upper ends of the movable support frames protrude from the top surface of the lower mold. This prior art demonstrates that a carpet product is formed by pressing a flat blank onto the forming surface of a mold to create a carpet product with a specified spatial shape.

[0004] Patent document CN113021849A, published on June 25, 2021, discloses a molding device and a manufacturing process for automotive carpets. The technical solution includes an upper mold and a lower mold. The top of the lower mold is used to place a semi-finished automotive carpet, and a partial concave area at the top of the lower mold is used to place anti-slip felt, with its top surface serving as the adhesive layer. An upward-pushing cylinder is provided. The upper mold presses down on the top surface of the semi-finished automotive carpet on the lower mold to form the carpet. In this state, the upward-pushing cylinder pushes the anti-slip felt upwards to the bottom surface of the semi-finished automotive carpet, which serves as the adhesive layer, thereby bonding the top surface of the anti-slip felt to the bottom surface of the semi-finished automotive carpet. The advantage of this prior art is that the molding device can also accommodate the assembly of other accessories for the automotive carpet.

[0005] In the prior art of the aforementioned patent, during the molding process, the flat carpet material is larger than the horizontal plane of the mold in order to fit the inner wall of the mold. During the molding process, the carpet material shrinks into the mold and fits the inner wall of the mold cavity to meet the requirements. However, due to the complex shape and structure of the mold cavity, the force on the surrounding area is not balanced during the shrinkage of the carpet material, which can easily cause excessive shrinkage on one side, thereby affecting the product quality. Therefore, there is an urgent need for a fully automatic assembly mechanism for multi-component automotive interior carpets to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automated assembly mechanism for multiple components of automotive interior carpets, in order to overcome the aforementioned shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A fully automated assembly mechanism for multi-component automotive interior carpets includes a base, on which a lower mold and an upper mold are sequentially arranged, forming a molding space for processing carpet raw materials. The mechanism also includes: multiple positioning platforms symmetrically arranged around the base; positioning rods movably mounted on the positioning platforms and capable of displacement in the X-axis and Y-axis directions via a guide assembly; the guide assembly providing resistance to prevent the positioning rods from approaching the molding space; and through holes on the edges of the carpet raw materials that match the positioning rods.

[0009] Preferably, the guide assembly includes two guide rods that movably pass through the positioning rod, the two guide rods extending along the X-axis and Y-axis directions respectively, and the two ends of the guide rods are slidably connected to the positioning platform and slide radially.

[0010] Preferably, the guide assembly includes sliding members at both ends of the guide rod, the side wall of the positioning platform is provided with sliding grooves that match the sliding members, and a first spring is sleeved on the side of the guide rod near the forming space, with the two ends of the first spring respectively abutting against the guide rod and the sliding members.

[0011] Preferably, the lower mold edge is provided with a first frame, and the upper mold is fitted with a second frame that can be elastically raised and lowered relative to it.

[0012] Preferably, a guide sleeve is fixedly provided on the side wall of the upper mold, and a guide rod that vertically moves through the guide sleeve is connected to the outer wall of the second frame through an extension. A second spring is sleeved on the guide rod, and the two ends of the second spring are respectively connected to the guide sleeve and the extension.

[0013] Preferably, a cutting groove is provided in the first frame, the cutting groove is connected to the upper end face of the first frame, and a cutting blade is movably disposed in the cutting groove.

[0014] Preferably, the outer wall of the first frame is provided with an inclined guide groove, and the cutter is fixedly provided with a guide block that matches the guide groove.

[0015] Preferably, a lifting member is fixedly provided on the side wall of the upper mold, and a support block is movably provided at the lower end of the lifting member near the upper mold. A protrusion that movably penetrates the outer wall of the first frame is fixedly provided on the cutting blade.

[0016] Preferably, the lower side of the support block is provided as an inclined surface, and the end of the protrusion is rotatably provided with a roller.

[0017] Preferably, a lifting groove is provided at the lower end of the blade groove, and a reset rod is elastically lifted and lowered in the lifting groove, with the upper end of the reset rod slidingly connected to the cutting blade.

[0018] In the above technical solution, the beneficial effects of the present invention are:

[0019] This fully automated assembly mechanism for multi-component automotive interior carpets uses positioning rods. Before the carpet material is molded in the molding space, it is positioned by the positioning rods through the through holes on the edge of the carpet material. Then, when the upper mold descends and closes with the lower mold, the molding space is compressed, causing the carpet material to conform to the shape of the mold and shrink into the molding space. The guide rods move towards the molding space in the X and Y directions under the action of the carpet material. However, since the movement of the positioning rods is restricted outside the molding space by the positioning table, it is ensured that the edges of the carpet material will not shrink into the molding space. This ensures that the shrinkage of each edge of the carpet material is appropriate and balanced, thereby avoiding product defects caused by excessive shrinkage of the carpet material.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0037] Please see Figure 1-11 This invention provides a fully automatic assembly mechanism for multiple components of automotive interior carpets, including a base 1, with a lower mold 2 and an upper mold 3 arranged sequentially above the base 1, forming a molding space for processing carpet raw materials between the lower mold 2 and the upper mold 3. The mechanism also includes: multiple positioning platforms 4 symmetrically arranged around the base 1; positioning rods 5 movably mounted on the positioning platforms 4, and having displacement in the X-axis direction and the Y-axis direction via a guide assembly. The guide assembly provides resistance to prevent the positioning rods 5 from approaching the molding space, and the edges of the carpet raw materials are provided with through holes matching the positioning rods 5.

[0038] Specifically, the base 1 supports the lower mold 2 and fixes its position; the upper mold 3 is connected to the hydraulic system and is raised and lowered by the hydraulic system, and the upper mold 3 is positioned directly above the lower mold 2; the upper end of the lower mold 2 and the lower end of the upper mold 3 are set as forming surfaces for carpet production and are matched with each other; a preset groove is opened on the upper forming surface of the lower mold 2 for pre-placing various accessories for carpet assembly. The forming space is the gap between the lower mold 2 and the upper mold 3. When the upper mold 3 descends to close the mold, the forming space is compressed and tends to the actual size of the carpet; when the upper mold 3 rises to separate the mold, the forming space expands to facilitate the entry of carpet raw materials or the removal of carpet products. Positioning platforms 4 are preferably four, symmetrically arranged at the four corners of the base 1; the horizontal cross-section of the positioning platform 4 is preferably rectangular; a groove is provided at the upper end of the positioning platform 4, and the positioning rod 5 is vertically arranged, with its lower end moving within the groove, which restricts the range of movement of the positioning rod 5; the height of the upper surface of the positioning platform 4 is similar to the closing height of the lower mold 2 and the upper mold 3. The guide assembly guides the movement of the positioning rod 5 in two branches: the X-axis and the Y-axis. These two branches can operate independently or in combination, thus adapting to the actual movement of a corner of the carpet material. The guide assembly also obstructs the positioning rod 5 through these two branches, ensuring that when no force is applied, the positioning rod 5 automatically remains at the corner furthest from the forming space within the groove at the upper end of the positioning platform 4. Four through holes are preferably located at the four corners of the carpet material. In practical use, the upper mold 3 rises and remains separated from the lower mold 2, and the forming space is relatively large, allowing the carpet material to easily pass through the forming space and be placed on the upper side of the lower mold 2. Then, the carpet material is positioned by the through holes at the four corners and the positioning rods 5. Next, the upper mold 3 descends under the drive of the hydraulic system and closes with the lower mold 2, compressing the forming space. This causes the carpet material to conform to the shape of the mold and shrink into the forming space. The guide rods 6 move towards the forming space in the X and Y directions under the drive of the carpet material. However, since the movement of the positioning rods 5 is restricted by the positioning table 4 and is outside the forming space, it is ensured that the edges of the carpet material will not shrink into the forming space. This ensures that the shrinkage of each edge of the carpet material is appropriate and balanced, thereby avoiding product defects caused by excessive shrinkage of the carpet material.

[0039] Compared with the prior art, the fully automatic assembly mechanism for multi-component automotive interior carpets proposed in this embodiment of the invention uses positioning rods 5. Before the carpet material is molded in the molding space, the positioning rods 5 position the carpet material through the through holes on the edge of the carpet material. Then, when the upper mold 3 descends and closes with the lower mold 2, the molding space is compressed, causing the carpet material to conform to the shape of the mold and shrink into the molding space. The guide rods 6 move closer to the molding space in the X and Y directions under the drive of the carpet material. However, since the movement of the positioning rods 5 is restricted outside the molding space by the positioning table 4, it is ensured that the edges of the carpet material will not shrink into the molding space. This ensures that the shrinkage of each edge of the carpet material is appropriate and balanced, thereby avoiding product defects caused by excessive shrinkage of the carpet material.

[0040] As a preferred technical solution in this embodiment, the guiding assembly includes two guide rods 6 that movably pass through the positioning rod 5. The extension directions of the two guide rods 6 are respectively along the X-axis and Y-axis. The two ends of the guide rods 6 are slidably connected to the positioning platform 4 and slide radially. Specifically, the guide rods 6 are horizontally arranged, and the axial directions of the two guide rods 6 are perpendicular to the axial direction of the positioning rod 5. The two guide rods 6 are staggered vertically and are arranged perpendicular to each other in their axial directions. The X-axis and Y-axis directions broadly refer to two mutually perpendicular directions on the horizontal plane, but here, they specifically refer to the direction in which the positioning rod 5 moves along the axial direction of the two guide rods 6. The guide rods 6 are movably arranged in the groove of the positioning platform 4. The guide rods 6 are perpendicular to the two opposite inner walls of the groove and parallel to the other two opposite inner walls. When the positioning rod 5 moves along the axial direction of one of the guide rods 6, it drives the other guide rod 6 to move radially to achieve movement in the X-axis or Y-axis direction. When the positioning rod 5 drives the two guide rods 6 to move radially, it achieves a combined movement in the X-axis and Y-axis directions.

[0041] As a preferred technical solution of this embodiment, the guide assembly includes sliding members 7 at both ends of the guide rod 6, and a sliding groove 8 matching the sliding member 7 is provided on the side wall of the positioning table 4. A first spring 9 is sleeved on the side of the guide rod 6 near the forming space. The two ends of the first spring 9 are respectively abutted against the guide rod 6 and the sliding member 7. Specifically, the sliding member 7 includes two baffles provided on the inner and outer sides of the groove of the positioning table 4. The two baffles are fixedly connected to the end of the guide rod 6. The sliding groove 8 is a horizontal through groove opened on the side wall of the groove of the positioning table 4. The end of the guide rod 6 moves through the sliding groove 8, and the two baffles respectively fit against the inner and outer walls of the groove to form a limit and guide, so that the guide rod 6 can move radially in the groove. One end of the first spring 9 abuts against the inner baffle of the sliding member 7 on one side. The first spring 9 prevents the positioning rod 5 from approaching the molding space from the X-axis or Y-axis. That is, when the edges of the carpet material connect with the positioning rod 5, it prevents the carpet material from shrinking into the molding space, ensuring more even shrinkage of each edge under external resistance and preventing excessive shrinkage. After the carpet is molded, the edges of the carpet material separate from the positioning rod 5, and the positioning rod 5 automatically returns to the corner furthest from the molding space within the groove under the action of the first spring 9. Furthermore, the first spring 9 ensures that when the carpet material is subjected to the tightening force generated during the mold closing process of the lower mold 2 and the upper mold 3, the positioning rod 5 can also tighten the four corners of the carpet material, thereby keeping the carpet material in a tensile state during molding and making it easier to fit tightly and accurately against the inner wall of the molding space.

[0042] In another embodiment of the present invention, a first frame 10 is provided on the edge of the lower mold 2, and a second frame 11 that can be elastically raised and lowered relative to the upper mold 3 is sleeved on it. Specifically, the first frame 10 is fixedly connected to the base 1 and surrounds the outside of the lower mold 2; the first frame 10 is rectangular; the second frame 11 is also rectangular and has the same horizontal cross-sectional size as the first frame 10; the elastic connection between the second frame 11 and the upper mold 3 allows the upper mold 3 to lower, causing the second frame 11 to first abut against the first frame 10, and then the upper mold 3 continues to lower relative to the second frame 11 to close with the lower mold 2; the arrangement of the first frame 10 and the second frame 11 can clamp the carpet. The carpet material is held in place by the four sides of the first frame 10. However, due to the elastic lifting of the second frame 11, the first frame 10 and the second frame 11 do not clamp the carpet material tightly. Instead, they generate frictional resistance that hinders the carpet material from moving between the mating surfaces of the first frame 10 and the second frame 11. As a result, the carpet material can be pressed and positioned before the lower mold 2 and the upper mold 3 are closed. On the other hand, during the process of the lower mold 2 and the upper mold 3 being closed, the shrinkage of the carpet material into the shaping space can be resisted by the clamping resistance of the four sides between the first frame 10 and the second frame 11. This ensures that the carpet material is in a state of being stretched to the four sides for molding, making it easier for the carpet material to adhere tightly and accurately to the inner wall of the molding space.

[0043] As a preferred technical solution in this embodiment, a guide sleeve 12 is fixedly provided on the side wall of the upper mold 3. A guide rod 14 that vertically moves through the guide sleeve 12 is connected to the outer wall of the second frame 11 through an extension 13. A second spring 15 is sleeved on the guide rod 14. The two ends of the second spring 15 are respectively connected to the guide sleeve 12 and the extension 13. Specifically, there are preferably 2-6 guide sleeves 12, which are evenly and symmetrically arranged on opposite sides of the upper mold 3. The extension 13 corresponds one-to-one with the guide sleeve 12 and is vertically aligned. The extension 13 is fixedly connected to the outer wall of the second frame 11. The upper end of the guide rod 14 is slidably sleeved with the guide sleeve 12. The second spring 15 is provided with... The second frame 11 is positioned such that it remains at its lowest position relative to the upper mold 3 when not affected by external forces. At this time, the lower end face of the second frame 11 is lower than the lowest height of the lower end of the upper mold 3. Thus, when the upper mold 3 descends, before the upper mold 3 and the lower mold 2 close, or in other words, before the upper mold 3 presses down on the carpet material, the second frame 11 can press down on the carpet material and cooperate with the first frame 10 to begin clamping the carpet material. In addition, when the upper mold 3 rises and begins to separate from the lower mold 2, the second spring 15 remains in a compressed state. That is, in the initial stage of the separation between the upper mold 3 and the lower mold 2, the first frame 10 and the second frame 11 still clamp the edge of the carpet material.

[0044] In another embodiment proposed by the present invention, a knife groove 16 is provided in the first housing 10. The knife groove 16 communicates with the upper end surface of the first housing 10. A cutting knife 17 is movably arranged in the knife groove 16. Specifically, the knife groove 16 is generally in the shape of a "square" and is opened in the four solid wall thicknesses of the first housing 10. A cutting knife 17 is provided in each of the four surfaces of the knife groove 16, and the upper end of the cutting knife 17 is serrated. A relief groove matching the knife groove 16 is provided at the lower end of the second housing 11. When the first housing 10 and the second housing 11 clamp the carpet raw material, the cutting knife 17 moves upward to pass through the clamping gap between the first housing 10 and the second housing 11, so as to cut the carpet raw material. Thus, the cutting between the edge margin of the carpet raw material and the carpet product in the forming space is achieved.

[0045] As a preferred technical solution of this embodiment, inclined guide grooves 18 are provided on the outer wall of the first housing 10, and guide blocks 19 matching the guide grooves 18 are fixedly arranged on the cutting knife 17. Specifically, at least two guide grooves 18 are provided on each outer wall of the first housing 10. The two guide grooves 18 have the same inclined direction, the same height, and are arranged at intervals. The arrangement of the guide blocks 19 and the guide grooves 18 makes the cutting knife 17 move in an obliquely upward and obliquely downward direction in the knife groove 16, so as to better cut and sever the carpet raw material. In addition, the horizontal feed of the cutting knife 17 in the knife groove 16 can cover both ends in the horizontal direction on one surface of the knife groove 16. The combination of the surfaces of the knife groove 16 can form a cutting trajectory that is also in the shape of a "square", ensuring a complete cut between the edge margin of the carpet raw material and the carpet product in the forming space. Further, with the setting of the positioning rod 5 and the first spring 9, the edge margin of the cut carpet raw material can be immediately separated from the forming space under the action of the first spring 9 pushing the positioning rod 5 to reset, that is, it promotes the separation between the edge margin of the carpet raw material and the carpet product in the forming space, so as to facilitate the subsequent independent extraction of the carpet product from the forming space without sticking to the margin of the carpet raw material.

[0046] As a preferred embodiment, a lifting member 20 is fixedly provided on the side wall of the upper mold 3, and a supporting block 21 is movably provided at the lower end of the lifting member 20 near the upper mold 3. A protrusion 22 that movably penetrates the outer wall of the first frame 10 is fixedly provided on the cutting blade 17. Specifically, the lifting member 20 includes a cantilever extending from the upper end of the upper mold 3 to the side and a hanging plate connected to the outer end of the cantilever. The hanging plate is spaced apart from the outer wall of the upper mold 3, and the side of the hanging plate near the upper mold 3 corresponds exactly to the outermost end of the protrusion 22. A retraction chamber 26 is provided at the lower end of the hanging plate, and the supporting block 21... One end is movably set inside the retraction chamber 26 and connected to the inner wall of the retraction chamber 26 via the third spring 27; the outer wall of the first frame 10 has a through groove for the movement of the protrusion 22, and the protrusion 22 moves with the cutter 17, that is, moves with the guidance of the guide groove 18 and the guide block 19; when the protrusion 22 is at its lowest position, it corresponds vertically to the support block 21, and when it is at its highest position, it deviates vertically from the support block 21; when the upper mold 3 descends to complete the mold closing with the lower mold 2, it drives the lifting member 20 to descend, so that the support block 21 corresponds to the lower height position of the protrusion 22 at its lowest position.

[0047] As a further preferred technical solution of this embodiment, the lower side of the support block 21 is set as an inclined surface, and the end of the protrusion 22 is rotatably provided with a roller 23. Specifically, the setting of the inclined surface on the lower side of the support block 21 allows the support block 21 to move into the retraction chamber 26 through the inclined surface squeezing action generated by the downward movement when it is driven down by the lifting member 20 and approaches the protrusion 22, so that the third spring 27 is compressed. Then, the support block 21 passes the protrusion 22 downward and is immediately ejected by the third spring 27 to be suspended directly below the protrusion 22. The setting of the roller 23 at the end of the protrusion 22 allows the upper mold 3 to rise and separate when it is driven up by the lifting member 20. The support block 21 rises, at which point it can directly lift the protrusion 22 upwards, thereby driving the cutter 17 to rise and cut the carpet material. At the same time, since the cutting blade 17 moves in an upward direction, the protrusion 22 also moves horizontally during its rise. The roller 23 can promote the horizontal movement of the protrusion 22 relative to the support block 21. In addition, when the protrusion 22 rises to its highest position, it deviates from the support block 21. As a result, the upper mold 3 continues to rise, and the cutter 17 completes the cutting and stops moving upwards. This achieves the operation of automatically cutting the edge excess of the carpet material by the cutter 17 in the early stage of carpet product forming and mold separation.

[0048] As a further preferred technical solution of this embodiment, a lifting groove 24 is provided at the lower end of the blade groove 16. A reset rod 25 is elastically lifted and lowered within the lifting groove 24. The upper end of the reset rod 25 is slidably connected to the cutting blade 17. Specifically, a fourth spring 28 is provided within the lifting groove 24. The upper and lower ends of the fourth spring 28 are respectively connected to the reset rod 25 and the lifting groove 24. The setting of the fourth spring 28 ensures that the reset rod 25 remains in the lowest position when no external force is applied, that is, it keeps the cutting blade 17 pulled down, so that the cutting blade 17 is kept entirely contained within the blade groove 16. Since the cutting blade 17 moves diagonally up and down, while the reset rod 25 moves vertically, the reset rod 25 is then slidably connected to the cutting blade 17 in the horizontal direction. This ensures that the cutting blade 17 and the reset rod 25 can rise and fall synchronously, while the relative horizontal displacement of the cutting blade 17 does not interfere with the rising and falling of the reset rod 25. In practical use, after the cutting blade 17 is driven by the upper mold 3 to cut the carpet material in the initial stage of mold separation, when the horizontal position of the protrusion 22 and the support block 21 deviates, the fourth spring 28 under tension can pull the reset rod 25 to descend and reset, thereby driving the cutting blade 17 to descend and reset, so as to automatically retract into the blade groove 16. Thus, after the upper mold 3 and the lower mold 2 separate, the cutting blade 17 is prevented from still extending out of the blade groove 16 to prevent the carpet product from being taken out of the forming space, thus avoiding the risk of injury from the cutting blade 17.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
