Description

Technical Field

[0001] The invention belongs to the technical field of automobile interior trim manufacturing automation, and in particular relates to a feeding device for automobile roof covering. Background Art

[0002] Currently, laminating the soft fabric of a car roof onto the car roof frame often requires independent operations such as cutting, rolling glue, and spraying water, which has poor continuity and low efficiency, that is, there is a problem of scattered processes.

[0003] In addition, the existing technology for laminating soft fabrics for automobile roofs still has the following problems:

[0004] (1) Low positioning accuracy: Traditional manual laying can easily cause the fabric to deviate on the conveyor belt, affecting the accuracy of the lamination position.

[0005] (2) Poor turning efficiency and safety: Automobile roof fabrics generally have an adhesive surface and a fabric surface. In order to prevent the adhesive surface from sticking to the conveyor line during transportation, they are generally laid with the adhesive surface facing up and the fabric surface facing down. Later, in order to press the automobile roof fabric down onto the inverted automobile roof frame, it is generally necessary to turn the automobile roof fabric over so that the adhesive surface of the automobile roof fabric faces down, making it easier for the adhesive surface to fit with the automobile roof frame after being pressed down. However, at present, manually turning over the fabric with the adhesive surface facing down can easily cause contamination or damage to the adhesive layer.

[0006] (3) Insufficient bending adaptability: The soft fabric required for the car roof needs to be pressed onto the curved car roof frame. Currently, before pressing the soft fabric (fabric surface + adhesive surface) onto the car roof frame, the curvature of the soft fabric needs to be adjusted to match the car roof frame. Traditional processes rely on manual or semi-automatic equipment. This can easily lead to wrinkles or loose fit. Summary of the Invention

These sensors are used to detect the distance between the edge of the soft fabric B on one side of the first and second material diverting sections 51a, 52b and the edge of the conveyor line C adjacent to the edge. The distance measured by the first distance measuring sensor 531 is designated as a first offset, and the distance measured by the second distance measuring sensor 532 is designated as a second offset.

When the third detection sensor 65 detects that there is no soft fabric B above the side of the conveying end of the first conveyor line C1 close to the flip plate 632, it means that the rear end has reached above the area where the flip plate 632 is located.

When the ninth motor 753 is running, the gear on it rotates to engage with different positions in the length direction of the ninth rack 752, thereby driving the ninth movable member 751 and the ninth rack 752 to slide in the x-axis direction relative to the eighth movable member 743.

[0155] The third telescopic mechanism 76 includes a tenth moving member 761 , a tenth rack 762 , and a tenth motor 763 .

[0157] The tenth rack 762 is disposed on the tenth moving member 761 and has a length direction along the x-axis.

[0158] The tenth motor 763 is fixed on the tenth movable member 761. The power output shaft of the tenth motor 763 has a gear that matches and engages with the tenth rack 762. When the tenth motor 763 is running, the gear on it rotates to engage with different positions in the length direction of the tenth rack 762, thereby driving the tenth movable member 761 to slide in the x-axis direction relative to the ninth movable member 751.

[0159] There are four bending control mechanisms 77, one at each of the two third telescopic mechanisms 76 in the x-axis direction and capable of displacement along the z-axis.

[0163] The lifting member 774 is embedded and slidably connected to the slide rail 771a on the fixing member 771, and the sliding direction is along the z-axis direction. The lifting member 774 has a fixed nut 774a, and the nut 774a has an internal threaded hole that matches the external thread of the screw rod 772 so that the screw rod 772 can pass through.

[0164] When the screw motor 773 is running, it drives the screw 772 to rotate, thereby driving the lifting member 774 to move along the z-axis direction through the screw nut 774a thereon.

[0165] The clamping mechanism 78 includes a plurality of clamping cylinders 781 and corresponding pairs of clamping jaws 782.

[0166] Specifically, in this embodiment, the number of the clamping mechanisms 78 is 18.

[0167] The number of the clamping claw cylinders 781 is 18. The clamping claw cylinders 781 are arranged on the third telescopic mechanism 76 and the lifting member 774.

[0168] The paired clamping jaws 782 are correspondingly arranged on the clamping jaw cylinder 781 and driven to open and close.

[0169] In the pair of clamping jaws 782, one of the clamping jaws located on the lower side in the z-axis direction is provided with a plurality of ejector pins 782a, and the plurality of ejector pins are arranged along the x-axis direction.

[0170] When the clamping jaw mechanism 78 clamps the soft fabric B, the ejector pin 782 a is used to penetrate the adhesive surface of the soft fabric B to prevent the adhesive thereon from directly adhering to the clamping jaw 782 .

[0171] The press 80 is pre-installed with a car roof frame. The press 80 is used to press the soft fabric B with the adhesive surface facing downwards, the curvature of which is adjusted by the fabric feeding and matching mechanism 70, down and onto the car roof frame.

[0175] Figure 24 This is a schematic diagram of the material shifting strategy of the material shifting portion when the calibration mechanism in this embodiment is used; Figure 25 This is a schematic diagram of the process of turning over a soft fabric by the fabric conveying and turning mechanism in an embodiment of the present invention; Figure 26 It is a diagram illustrating the process of bending soft fabric by the fabric feeding and matching mechanism in an embodiment of the present invention.

[0176] like Figures 1 to 26 As shown, the operation process of the automobile roof covering feeding device 100 and the control process of the controller in this embodiment include the following steps S10 to S90:

[0177] S10, manually pulling out a portion of the soft fabric B in the material roll A, and pressing the lower pressing roller shaft 12 onto the abutting plate 11.

[0178] S20, the fifth control unit controls the pressing roller shaft 12 to operate so as to unroll and transport the soft fabric B in the roll A.

[0179] At step S30, the fifth control unit controls the pulling mechanism 20 to clamp and pull the leading end of the soft fabric B delivered by the cutting mechanism 10. After the pulling reaches a set value, the cutting mechanism 10 cuts the soft fabric B delivered by the set distance through the cooperation of the guillotine 13 and the guillotine 14.

[0180] S40 , the fifth control unit controls the glue rolling mechanism 30 to roll glue on the upper surface of the cut soft fabric B conveyed by the conveyor belt M to form a glue surface.

[0181] S50 , the fifth control unit controls the water spraying mechanism 40 to spray a catalyst and water on the adhesive surface of the soft fabric B after adhesive rolling that is transported by the conveyor belt M.

[0182] S60, when the soft fabric B after the adhesive surface is sprayed with catalyst and water is transferred to the conveyor line C area of ​​the conveyor belt M, the first control unit and the second control unit control the calibration mechanism 50 to perform position calibration on the soft fabric B, specifically including the following steps S61 to S63:

[0183] S61: During the conveyor line C conveying the soft fabric B, the second control unit detects via the first detection sensor 52 that the soft fabric B has been conveyed to a predetermined position, thereby controlling the driver of the conveyor line C to stop operating. Specifically, when the second control unit detects via either of the two first detection sensors 52 that the soft fabric B conveyed by the conveyor line C has been conveyed to the predetermined position, the driver is controlled to stop operating.

[0184] S62, when the first control unit detects through the second control unit that the conveyor line C stops running, it controls the four material-selecting parts 51 to cooperate with each other, and adjusts the offset of the soft fabric B according to the preset strategy based on the offset measured by the first distance measuring sensor part 531 and the second distance measuring sensor part 532.

[0185] Specifically, the first control unit (not shown in the figure) is connected to the four first motors 5114, the four second motors 5124, the four lifting cylinders 5131, the first ranging sensor unit 531, the second ranging sensor unit 532 and the second control unit. When the first control unit detects through the second control unit that the conveyor line C stops running, it receives the first offset and the second offset, and compares the differences between the first offset and the second offset and the preset values, which are recorded as Δd1 and Δd2 respectively.

[0186] The first control unit controls the lifting cylinder 5131 of at least one of the four material-discharging parts 51 according to Δd1 and Δd2, so as to drive the lifting moving part 5132 to press down along the z-axis direction and make the material-discharging needle 514 penetrate the soft fabric B and then pull the soft fabric B toward the outside of the conveyor line C along the y-axis direction, so that the first offset and the second offset finally reach roughly the same preset value (the preset value is set according to the y-axis width of the conveyor line C and the width of the soft fabric B, so that the soft fabric B can be adjusted to the center of the conveyor line C).

[0187] Each time the first control unit controls the first material digging part 51a, the second material digging part 51b, the third material digging part 51c or the fourth material digging part 51d to press down along the z-axis direction and make the material digging needle 514 penetrate the soft fabric B and then pull the soft fabric B along the y-axis direction toward the outside of the conveyor line C, it controls the corresponding first material digging part 51a, the second material digging part 51b, the third material digging part 51c or the fourth material digging part 51d to move upward along the z-axis direction and return to its original position.

[0188] The control conditions of the first control unit are as follows:

[0189] (1) When Δd1>0, the first control unit controls the first material-discharging portion 51a to drive the material-discharging needle 514 thereon to press downward along the z-axis direction, so that the material-discharging needle 514 penetrates the soft fabric B and then pulls the soft fabric B toward the outside of the conveyor line C along the y-axis direction, thereby ultimately making the first offset measured by the first distance-measuring sensor 531 approximately reach the preset value.

[0190] (2) When Δd1<0, the first control unit controls the third material-discharging portion 51c to drive the material-discharging needle 514 thereon to press down along the z-axis direction and make the material-discharging needle 514 penetrate the soft fabric B and then pull the soft fabric B toward the outside of the conveyor line C along the y-axis direction, so that the first offset measured by the first distance measuring sensor portion 531 finally reaches approximately the preset value.

[0191] (3) When Δd1 = 0, both the first material shifting portion 51 a and the third material shifting portion 51 c do not operate.

[0192] (4) When Δd2>0, the first control unit controls the second material-discharging portion 51b to drive the material-discharging needle 514 thereon to press down along the z-axis direction and make the material-discharging needle 514 penetrate the soft fabric B and then pull the soft fabric B toward the outside of the conveyor line C along the y-axis direction, so that the second offset measured by the second distance measuring sensor portion 532 finally reaches approximately the preset value.

[0193] (5) When Δd2<0, the first control unit controls the fourth material-discharging portion 51d to drive the material-discharging needle 514 thereon to press down along the z-axis direction and make the material-discharging needle 514 penetrate the soft fabric B and then pull the soft fabric B toward the outside of the conveyor line C along the y-axis direction, so that the second offset measured by the second distance measuring sensor portion 532 finally reaches approximately the preset value.

[0194] (6) When Δd2=0, the second material shifting portion 51b and the fourth material shifting portion 51d are not in operation.

[0195] (7) When Δd1 = 0 and Δd2 = 0, the first control unit stops controlling the first material shifting portion 51 a , the second material shifting portion 51 b , the third material shifting portion 51 c or the fourth material shifting portion 51 d .

[0196] In the above control process / conditions, since the offset measured by the first distance measuring sensor part 531 and the second distance measuring sensor part 532 is not the offset of the soft fabric B directly below the material needle 514 (there is a certain deviation in the distance in the x-axis direction), the first control unit will drive the corresponding second motor 5124 in advance according to the installation status of the first distance measuring sensor part 531 and the second distance measuring sensor part 532 before controlling the material needle 514 to press down along the z-axis direction, so that the material needle 514 is displaced in the x-axis direction to eliminate the deviation.

[0197] S63, after the adjustment is completed, the second control unit controls the conveyor line C to continue running to perform subsequent processes.

[0198] S70, the third control unit controls the fabric conveying and turning mechanism 60 to turn over the soft fabric B adjusted in step S63, including the following steps S71 to S76:

[0199] S71, after the second detection sensor 62 detects that the front end has been transported via the second conveyor line C2 and drooped along the yz plane to the opening of the front end clamp 6132, the front end clamp is driven by the front end clamp cylinder 6131 to control the front end clamp 6132 to clamp the front end. Subsequently, the third motor 6114 is operated to control the third moving member 6113 to drive the front end clamped by the front end clamp 6132 to move along the x-axis in the direction opposite to the transport direction. During the displacement process, the first rotary drive motor 6122 is operated in conjunction to drive the first roller 6121 to rotate, thereby driving the front end clamped by the front end clamp 6132 thereon to rotate around the y-axis so that the front end is finally moved along the x-axis in the direction opposite to the transport direction.

[0215] According to the present embodiment, a feeding device for covering a car roof is provided, which is arranged on a whole conveyor belt, and is used to convey the soft fabric in the material roll and cover it on the car roof frame after corresponding processing. The soft fabric is initially made of fabric material, because it includes: a pulling mechanism, which is used to pull the soft fabric in the material roll onto the conveyor belt; a cutting mechanism, which is located between the pulling mechanism and the material roll, and is used to unwind and cut the soft fabric pulled to a preset length by the pulling mechanism; a glue rolling mechanism, which is used to roll glue on the upper surface of a whole rectangular piece of soft fabric after cutting to form a glue surface; a water spraying mechanism, which is used to spray glue on the glue Catalyst and water are sprayed on the surface; a calibration mechanism is used to calibrate the plane position of the soft fabric material treated by the water spraying mechanism on the conveyor belt to the center of the conveyor belt; a fabric conveying and turning mechanism is used to turn over the soft fabric material calibrated by the calibration mechanism so that its glue side faces downward and is conveyed to the next station; a fabric feeding and matching mechanism is used to adjust the bending degree of the soft fabric material in the length direction to match the bending degree of the automobile roof frame and convey it to the next station; a press is pre-installed with an automobile roof frame, which is used to press the soft fabric material with adjusted bending degree and glue side facing downward and cover it in the shown automobile roof frame.

[0216] Therefore, the feeding device for covering the automobile roof of this embodiment has the following beneficial effects: it integrates eight major mechanisms (cutting mechanism, pulling mechanism, glue rolling mechanism, water spraying mechanism, calibration mechanism, fabric conveying and flipping mechanism, fabric feeding and matching mechanism, and press) into a conveyor belt, realizing the automation of the entire process from unwinding the fabric to covering the automobile roof frame, reducing manual intervention.

[0217] Furthermore, the length direction of the conveyor belt is recorded as the x-axis direction, the width direction of the conveyor belt is recorded as the y-axis direction, and the direction perpendicular to the xy plane is recorded as the z-axis direction. The material pulling mechanism includes: a material pulling guide rail and a material pulling rack, which are fixed to the top of the conveyor belt next to the cutting mechanism through an external bracket, and its length direction is along the x-axis direction; a material pulling movable part, the track is embedded in the material pulling guide rail so that it can move along the x-axis direction; a material pulling motor, which is fixed on the material pulling movable part, and the power output shaft of the material pulling motor has a gear that matches and engages with the material pulling rack. When the material pulling motor is running, the gear on it rotates to engage with different positions in the length direction of the material pulling rack, thereby driving the material pulling movable part to move in the x-axis direction; a material pulling claw driving cylinder, which is distributed along the y-axis direction on the material pulling movable part and is driven by it to move along the x-axis direction; a material pulling claw, which is correspondingly arranged on the material pulling claw driving cylinder and is driven by it to clamp the soft fabric fabric that passes through the cutting mechanism. With this arrangement, the pulling distance can be precisely controlled by the pulling mechanism driven by the rack and pinion.

[0218] The cutting mechanism further includes an abutment plate for laying the soft fabric from the feed roll onto it; a pressure roller for pressing the soft fabric on the abutment plate and rolling it so that it is pulled by the pull mechanism; and a guillotine and a shearing mouth for cooperating to unwind and cut the soft fabric, which has been pulled to a predetermined length by the pull mechanism. This arrangement, through the combination of guillotine cutting and pressure roller transmission, ensures smooth and continuous cutting.

[0219] Furthermore, the conveyor belt in the area where the calibration mechanism is located is recorded as a conveyor line, the length direction of the conveyor line is recorded as the x-axis direction, the width direction of the conveyor line is recorded as the y-axis direction, and the direction perpendicular to the xy plane is recorded as the z-axis direction. One side of the soft fabric fabric is a rubber surface, the rubber surface of the soft fabric fabric is away from the conveyor line, and the fabric surface of the soft fabric fabric is close to the conveyor line. The calibration mechanism includes at least 4 material-dipping parts, and the material-dipping part has a material-dipping needle with a needle head pointing downward along the z-axis direction. The material-dipping part can be displaced along the x-axis direction, the y-axis direction and the z-axis direction. Several material-dipping parts are distributed above the edge areas on both sides of the soft fabric fabric along the x-axis direction and at least above the four corner areas of the soft fabric fabric. At least one of the material-dipping parts presses down along the z-axis direction and causes the material-dipping needle to penetrate the soft fabric fabric and then pull the soft fabric fabric toward the outside of the conveyor line along the y-axis direction, so that the plane position of the soft fabric fabric on the conveyor line is finally calibrated to the center of the conveyor line. The material-selecting part includes: an x-direction moving assembly, including a first guide rail, a first rack, a first moving part and a first motor. The first guide rail and the first rack are fixed to the area above the conveyor line through an external fixed position bracket. The length directions of the first guide rail and the first rack are both along the x-axis direction. The first moving part track is embedded in the first guide rail so as to be movable along the x-axis direction. The first motor is fixed on the first moving part. The power output shaft of the first motor has a gear that matches and meshes with the first rack. When the first motor is running, the gear on it rotates to mesh with different positions in the length direction of the first rack, thereby driving the first moving part to move in the x-axis direction; a y-direction moving assembly, including a second guide rail, a second rack, a second moving part and a second motor. The second guide rail and the second rack are fixed on the first moving part. The length directions of the second guide rail and the second rack are both along the y-axis direction. The second moving part The track is embedded in the second guide rail so that it can move along the y-axis direction. The second motor is fixed on the second moving part. The power output shaft of the second motor has a gear that matches and meshes with the second rack. When the second motor is running, the gear on it rotates to mesh with different positions in the length direction of the second rack, thereby driving the second moving part to move in the y-axis direction; the z-direction moving assembly includes a lifting cylinder and a lifting moving part. The lifting cylinder is arranged on a side of the second moving part close to the conveyor line and its running direction is along the z-axis direction. The lifting moving part is driven by the lifting cylinder to move in the z-axis direction; a material discharging needle is fixed on the lifting moving part and its needle head is facing downward along the z-axis direction; and a limiting roller is located next to the material discharging needle. The wheel surface of the limiting roller is parallel to the yz plane. In the z-axis direction, the bottom of the limiting roller is higher than the position of the needle tip of the material discharging needle, and the corresponding height difference is less than the thickness of the soft fabric. Such a setting has the following beneficial effects: (1) The feeding needle penetrates the edge of the fabric to correct the deviation, and adopts the strategy of "only pulling but not pushing" to effectively adjust the position of the soft fabric; (2) The three-axis movement + limiting roller design of the feeding part prevents the feeding needle from penetrating too deeply and tearing the fabric.

[0220] Furthermore, the conveyor belt in the area where the fabric conveying and flipping mechanism is located is recorded as a conveyor line, one side of the soft fabric fabric is a rubber surface, the rubber surface of the soft fabric fabric is away from the conveyor line, and the fabric surface of the soft fabric fabric is close to the conveyor line, and the conveyor line has a driver for driving the transmission, and the conveyor line is divided into two sections along its transmission direction, which are recorded as the first conveyor line and the second conveyor line respectively. The soft fabric fabric is conveyed from the first conveyor line to the second conveyor line, and the length direction of the conveyor line is recorded as the x-axis direction, the width direction of the conveyor line is recorded as the y-axis direction, and the direction perpendicular to the xy plane is recorded as the z-axis direction. The fabric conveying and flipping mechanism includes: a front-end clamping assembly, including a first moving part, a first rotating part and a first clamping claw part, the first moving part is movably arranged below the conveyor line along the x-axis direction through a guide rail, the first rotating part is arranged on the first moving part and can rotate around the y-axis direction, and the first clamping claw part is arranged on the first rotating part. The first clamping portion is driven by the rotating portion to rotate, and the first clamping portion is used to clamp the front end of the soft fabric material that has been conveyed by the conveyor line and drooped to a specified position in the yz plane direction. The flap assembly is arranged between the first conveyor line and the second conveyor line, and is used to lift the rear end of the soft fabric material conveyed above it, with the lifted rear end oriented at an angle of not less than 90 degrees with the conveying direction. The rear end clamping assembly includes a second movable portion, a third movable portion, a second rotating portion, and a second clamping portion. The second movable portion is movable above the conveyor line along the x-axis via a guide rail, the third movable portion is movable along the z-axis via a guide rail on the second movable portion, the second rotating portion is mounted on the third movable portion and is rotatable about the y-axis, and the second clamping portion is mounted on the second rotating portion and driven by the second rotating portion to rotate, and the second clamping portion is used to clamp the lifted rear end of the flap assembly. In this arrangement, the front and rear end clamping portions cooperate with the flap assembly to achieve mid-air flipping of the fabric (with the rubber surface not contacting the equipment), thereby preventing contamination of the conveyor belt.

[0221] Furthermore, the initial positions of the calibration mechanism and the fabric conveying and turning mechanism are located at the same position on the conveyor belt. This arrangement allows the calibration and turning mechanism positions to be reused, shortening the production line length and saving space.

[0222] Furthermore, when the bending degree of the soft fabric is adjusted in the fabric feeding and matching mechanism, the fabric surface is facing upward and the rubber surface is facing downward, the length direction of the soft fabric is recorded as the x-axis direction, the width direction is recorded as the y-axis direction, and the z-axis direction is perpendicular to the xy plane. The fabric feeding and matching mechanism includes: a base, which is fixed in position; a first telescopic mechanism, which is telescopically arranged on the base along the x-axis direction through a guide rail; a tensioning mechanism, which is 2 in number and is movably arranged on the first telescopic mechanism along the y-axis direction through a guide rail and the distance between the two tensioning mechanisms in the y-axis direction is adjustable; a lifting mechanism, which is 2 in number and is correspondingly arranged on the tensioning mechanism in a liftable manner along the z-axis direction through a guide rail; a second telescopic mechanism, which is 2 in number and is telescopically arranged on the lifting mechanism along the x-axis direction through a guide rail; a third telescopic mechanism, which is 2 in number and is telescopically arranged on the lifting mechanism along the x-axis direction through a guide rail The second telescopic mechanism comprises at least four bending control mechanisms, each disposed at two ends of at least two third telescopic mechanisms in the x-axis direction and displaceable in the z-axis direction, with its initial z-axis position flush with the third telescopic mechanism; and a plurality of clamping mechanisms, disposed on the bending control mechanism and the third telescopic mechanism to form two rows arranged in the x-axis direction, with the jaw openings of the clamping mechanisms facing the interior of the automobile roof fabric feeding and matching device along the y-axis. The two rows of clamping mechanisms cooperate to clamp the ends of the soft fabric pre-delivered along the x-axis between the two rows of clamping mechanisms in the y-axis direction. The two rows of clamping mechanisms are indirectly driven by the tensioning mechanism, the first telescopic mechanism, the second telescopic mechanism, the third telescopic mechanism, the lifting mechanism, and the bending control mechanism to perform the respective processes of tensioning, three-stage conveying, lifting, and bending the soft fabric. This arrangement has the following beneficial effects: through the linkage of the multi-stage telescopic / lifting mechanisms, the bending curvature of the fabric can be precisely controlled.

[0223] Furthermore, the feeding device for covering the automobile roof also includes a conveying mechanism and a die-changing station. The conveying mechanism is used to continue to convey the automobile roof frame after it has been pressed with the soft fabric, and the die-changing station is used to store the automobile roof frame that has not been pressed with the soft fabric. Such an arrangement has the following beneficial effects: (1) the conveying mechanism extends the automation process and improves the overall production capacity; (2) the die-changing station pre-stores the frames to achieve uninterrupted feeding.
