DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 2-15 As shown, the present invention discloses an automatic material strip laying device, including a laying workbench 1, an alignment drive mechanism 2, an unwinding mechanism 3, a conveying component 5, a cutting mechanism 6, a pulling-out mechanism 7 and a liftable compacting roller 8.

[0038] The unwinding mechanism 3, the conveying assembly 5, the cutting mechanism 6 and the pulling mechanism 7 are arranged in sequence. The unwinding mechanism 3 is used to unwind the material strip. The conveying assembly 5 is used to guide and convey the material strip displayed from the unwinding mechanism 3. The cutting mechanism 6 is used to cut the material strip so as to cut the material strip after the material strip is laid and to lay the next workpiece. The pulling mechanism 7 is used to pull the end of the material strip to pass directly under the compaction roller 8. After the end of the material strip is pulled out, the compaction roller 8 can be used to press the end of the material strip down and fix it on the workpiece for subsequent laying.

[0039] The paving workbench 1 is used to support the workpiece, and a slot 11 for clamping and fixing the workpiece is provided on the top of the paving workbench 1. The compaction rollers 8 are located above the paving workbench 1 and are arranged along the material strip laying path. The position of one of the compaction rollers 8 corresponds to the position where the conveying assembly 5 outputs the material strip. Each compaction roller 8 is controlled to rise and fall by a cylinder and can press down the workpiece. The alignment drive mechanism 2 is used to drive the paving workbench 1 to move, thereby causing the compaction rollers 8 to roll relative to the workpiece along the material strip laying path, thereby laying and compacting the material strip on the workpiece.

[0040] Through the sequential actions of the unwinding mechanism 3, the conveying assembly 5 and the pulling-out mechanism 7, the material strip can be automatically guided and transmitted, and the end of the material strip can be guided under the compaction roller. In combination with the moving alignment action of the alignment drive mechanism 2 and the rolling compaction action of the compaction roller 8, the material strip can continue to be drawn out and accurately laid and compacted on the workpiece.

[0041] When used in the preforming process of bicycle rims, that is, when the preforming mold 1' is used as a workpiece, the above-mentioned slot 11 is in a circular ring shape that matches the preforming mold 1'. The above-mentioned unwinding mechanism 3 can place a composite material roll with a material tape and a backing film. The side of the unwinding mechanism 3 is also provided with a reeling mechanism 4 for reeling in the backing film. The reeling mechanism 4 includes a reeling shaft 41 and a reeling motor (not shown) for driving the reeling shaft 41 to rotate. The compacting roller 8 includes a first roller 81 and a plurality of second rollers 82, wherein the position of the first roller 81 corresponds to the position where the conveying assembly 5 outputs the material tape, and the second rollers 82 are arranged directly above the preforming slot 11'. The alignment drive mechanism 2 includes a vertical rotating drive member 21 and a lifting drive member 22, and the vertical rotating drive member 21 is drivingly connected to the lifting drive member 22. The paving workbench 1 is drivingly connected to the vertical rotating drive member 21 or the lifting drive member 22. The alignment drive mechanism 2 can drive the preform mold 1' on the paving workbench 1 to rise and fall close to the compacting roller 8, and drive the preform mold 1' to rotate, so that the compacting roller 8 rolls along the preform groove 11' to compact the material belt.

[0042] The conveying assembly 5 includes a tension roller group 51 and a plurality of roller conveying mechanisms 52, wherein the tension roller group 51 is used to unfold the material strip and control the tension, and the roller conveying mechanisms 52 are located directly above the material laying workbench 1 and are arranged one by one downstream of the tension roller group 51 to guide and convey the material strip. In this embodiment, the roller conveying mechanisms 52 are arranged at intervals along the arc-shaped or spiral material strip conveying path to connect the arc-shaped or annular material strip laying path, so as to better adapt to the application scenario with a large laying curvature such as bicycle rim preforming.

[0043] The pair of roller conveying mechanisms 52 each include a conveying seat 521, a driving motor 522, and two conveying rollers 523 arranged up and down; the conveying rollers 523 are rotatably arranged on the conveying seat 521, and a first material passage 524 for the material supply belt to pass through is formed between the two conveying rollers 523; the driving motor 522 is fixedly connected to the conveying seat 521, and drives the conveying rollers 523 to rotate. Among the two conveying rollers 523, at least one conveying roller 523 is a conical roller, so that the material belt can be pre-bent before laying, and the material belt can be guided to move along the spiral conveying path, thereby better connecting the arc-shaped and annular material belt laying path, and laying the material belt in place. In this embodiment, both conveying rollers 523 are conical rollers, one of which is an active roller connected to the driving motor 522, and the other is a passive roller.

[0044] The transmission seat body 521 includes a main body 5211 and a hanger 5212. The hanger 5212 is in an inverted U shape and is slidably connected to the main body 5211. One of the two transmission rollers 523 is directly rotatably arranged on the main body 5211, and the other is rotatably mounted on the hanger 5212. Correspondingly, the pair of roller transmission mechanism 52 is also provided with an adjustment drive member 525, which is fixedly connected to the main body 5211 and can drive the hanger 5212 to slide. The driving direction of the adjustment drive member 525 is perpendicular to the rotation axis of the transmission roller 523 mounted on the hanger 5212. By adjusting the drive member 525, the hanger 5212 and the transmission roller 523 thereon can be driven to move and move closer to or away from the other transmission roller 523, thereby adjusting the distance between the two transmission rollers 523 to adapt to the transmission operation of material strips of different thicknesses.

[0045] A supporting platform 53 is provided between each pair of roller conveying mechanisms 52. The supporting platform 53 can be provided separately from the pair of roller conveying mechanisms 52, or can be fixedly connected to the main body 5211 of the conveying seat body 521. Two limiting bosses 531 are provided at intervals on the top of the supporting platform 53. The two limiting bosses 531 are respectively located on both sides of the material belt conveying path, and the opposite side wall surfaces are vertically arranged arc surfaces. A second material transfer channel 532 for the feed belt to pass through is formed between the two limiting bosses 531, and the position of the first material transfer channel 524 corresponds to the position of the second material transfer channel 532. Through each supporting platform 53, each pair of roller conveying mechanisms 52 can be connected, so that the material belt conveying path is smooth and the material belt is guided smoothly.

[0046] Furthermore, the conveying seat body 521 in each pair of roller conveying mechanisms 52 is rotatably arranged, and the rotation axis of the conveying seat body 521 is perpendicular to the material belt conveying path. By rotating and adjusting the position of the conveying seat body 521, the first material transfer channel 524 can be rotated accordingly, and then the material belt conveying path can be fine-tuned, further ensuring a smooth connection between each first material transfer channel 524.

[0047] When the material strip to be laid is a narrow strip, a plurality of annular feeding grooves 5231 are provided on the outer wall of the conveying roller 523. The feeding grooves 5231 are arranged with the rotation axis of the conveying roller 523 as the center, and are arranged at intervals along the rotation axis of the conveying roller 523. The two conveying rollers 523 are in rolling contact with each other, and the positions of the feeding grooves 5231 on the two conveying rollers 523 are staggered with each other. The feeding grooves 5231 on any conveying roller 523 and the outer wall of the other conveying roller 523 are combined to form a first material transfer channel 524. Through each first material transfer channel 524, multiple material strips can be accommodated, guided, and conveyed, and the material strips can be separated and limited to avoid overlapping between the material strips and affecting the conveying.

[0048] Two baffle plates 526 are also provided in the roller conveying mechanism 52. The two baffle plates 526 are arranged up and down and are detachably connected to the sides of the conveying seat body 521. The positions of the baffle plates 526 correspond to the positions of the conveying rollers 523 one by one, and the two baffle plates are adjustably mounted on the seat body along directions perpendicular to the rotation axes of the corresponding conveying rollers 523. The sides of the baffle plates 526 extend toward the conveying direction of the material belt to form a plurality of limiting comb teeth 5261. The limiting comb teeth 5261 are arranged one by one in the feeding trough 5231, and can divide the first material transfer channel 524 up and down. By changing the positions of the limiting comb teeth 5261, the size of the space in the first material transfer channel 524 where the material belt passes can be changed to adapt to material belts of different thicknesses for better guidance and transmission.

[0049] The cutting mechanism 6 includes a cutting seat 61, a lifting and pressing plate 64, a cutter 65, a cutter driving member 66 and other components. The cutting seat 61 is provided with a material feeding trough 62 for supporting the material strip, and the material feeding trough 62 is connected to the first material feeding channel 524 located at the most downstream, and a cutter avoidance groove 63 is provided at the bottom of the material feeding trough 62. The lifting and pressing plate 64 is arranged above the side of the cutter avoidance groove 63 away from the pull-out mechanism 7, and after the laying is completed, the material strip fixed in the material feeding trough 62 can be pressed down for cutting. The cutter driving member 66 can drive the cutter 65 to pass through the cutter avoidance groove 63, thereby cutting the material strip and ending the laying operation.

[0050] The pull-out mechanism 7 includes a pull-out guide rail 71, a lifting jaw 72 and a pull-out drive 73, wherein the pull-out drive 73 is used to drive the lifting jaw 72 to slide along the pull-out guide rail 71, the pull-out guide rail 71 is located between the cutting mechanism 6 and the first roller 81, and the shape matches the material strip laying path, and is used to guide the lifting jaw 72 to move between the cutting mechanism 6 and the first roller 81, and the lifting jaw 72 is used to grab the end of the material strip from the cutting mechanism 6. The pull-out mechanism 7 can pull the material strip from the cutting mechanism 6, and guide the end of the material strip to the bottom of the first roller 81 for preliminary compaction so as to be laid. In this embodiment, the pull-out guide rail 71 is set on the side of the preformed groove 11', and the guide track is in the shape of an arc coaxial with the preformed groove 11'.

[0051] Since there is a certain distance between the position where the lifting clamp 72 is located after pulling out the material strip and the cutting mechanism 6, in order to prevent the section of the material strip from being offset or deformed during laying, the device is also provided with a correction mechanism 9. The correction mechanism 9 includes an arc-shaped vertical plate 91, a correction baffle 92 and a correction drive 93. The arc-shaped vertical plate 91 and the correction baffle 92 are both arranged on the output side of the cutting mechanism 6. The correction baffle 92 is in the shape of an arc strip, and the cross-section of the correction baffle 92 perpendicular to its own length direction is in the shape of a U-shaped opening for the material strip to enter and exit. The entire correction baffle 92 is tilted, with one end facing the material trough 62 and the other end facing the first roller 81. One side of the opening on the correction baffle 92 faces the arc-shaped vertical plate 91. The correction drive 93 is used to drive the correction baffle 92 to approach or move away from the arc-shaped vertical plate 91. When the deflection correcting driving member 93 drives the deflection correcting baffle 92 away from the curved vertical plate 91, the lifting clamp 72 can be avoided so as to pull out the material strip. When laying the material strip, the deflection correcting driving member 93 can drive the deflection correcting baffle 92 close to the curved vertical plate 91 to prevent the material strip from deflecting and deforming.

[0052] When the laying equipment is in operation, the material strip can be unwound, conveyed, pulled out and preliminarily compacted by the unwinding mechanism 3, the conveying assembly 5, the pulling-out mechanism 7 and the first roller 81, and then the material strip can be accurately laid by the laying workbench 1, the first roller 81, the second roller 82 and the deviation correction mechanism 9. After that, the material strip can be cut by the cutting mechanism 6 to end the laying. It can be seen that the material strip can be accurately laid by the equipment, which effectively improves the quality and efficiency of the material strip laying, ensures the stability of the production process and the consistency of the products, and at the same time reduces the labor intensity of employees, reduces labor costs, and eliminates the safety hazards of manual operations. It is especially suitable for use scenarios with large laying curvatures such as bicycle rim preforming.
