Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of wind turbine blades, in particular to an automatic wire winding machine for a bolt sleeve of a wind turbine blade. Background Art

[0002] A wind turbine is a power generation device that converts wind energy into mechanical energy and then into electrical energy through blades. The blades are the key components of a wind turbine. Generally, a high-strength bolt sleeve is embedded in the end face of the root of the blade and connected to the hub through bolts. In order to enhance the strength of the bolt sleeve embedded in the blade, glass fiber is wound on the surface of the bolt sleeve. In the prior art, the process of winding glass fiber on the bolt sleeve mainly adopts a semi-automatic winding scheme, that is, manually inserting a bolt sleeve into a mandrel with rotating power, and manually fixing several strands of glass fiber heads on the bolt sleeve, and then starting the mandrel to rotate, and the glass fiber is wound on the bolt sleeve. After the winding is completed, the tail of the glass fiber is manually cut off, and the tail of the glass fiber is manually tied on the bolt sleeve to prevent the glass fiber from scattering from the bolt sleeve. However, in the above process, when the glass fiber is manually fixed to the bolt sleeve, the length reserved for the head of the glass fiber is inconsistent due to the proficiency of the operator and the stability of the operation. After the winding is completed, there is a risk of the knot being detached due to the different quality of manual knotting. Moreover, the glass fiber is very sharp and can easily scratch fingers during manual winding. At the same time, glass fiber dust is very harmful to the human body if inhaled. In addition, the winding process has a low degree of automation, requiring one person to focus on the loading, winding, knotting and unloading processes of a production line, but not on the handling of the bolt sleeves, which requires a lot of labor and has low results.

Detailed implementation mode

[0029] The following further describes the present utility model with reference to the accompanying drawings through specific embodiments:

[0030] As Figures 1 to 12 shown, an automatic wire winding machine for a bolt sleeve of a wind power blade includes a frame 1. A support assembly 10, a wire guiding and tensioning assembly 40, and a knotting and wire winding assembly 70 are arranged on the frame 1. The support assembly 10 is used to fix the bolt sleeve 100 and drive the bolt sleeve 100 to rotate.

The movable seat 30 is connected with a first driving member 11, and the first driving member 11 is used to drive the movable seat 30 to move on the first slide rail 101. The first positioning sleeve 21 is connected with a second driving member 12, and the second driving member 12 is used to drive the first positioning sleeve 21 to rotate on the fixed seat 20. During use, the first driving member 101 drives the movable seat 30 and the second positioning sleeve 31 to move away from the fixed seat 20 on the first slide rail 101, so that the distance between the first positioning sleeve 21 and the second positioning sleeve 31 is greater than the length of the bolt sleeve 100 of the wind turbine blade. Then, the bolt sleeve 100 is placed between the first positioning sleeve 21 and the second positioning sleeve 31. The first driving member 101 drives the movable seat 30 and the second positioning sleeve 31 to move toward the fixed seat 20 on the first slide rail 101, and the first positioning sleeve 21 and the second positioning sleeve 31 are clamped at both ends of the bolt sleeve 100. Then, the second driving member 12 drives the first positioning sleeve 21 to rotate on the fixed seat 20, and at the same time, the bolt sleeve 100 and the second positioning sleeve 31 rotate accordingly.

[0032] Furthermore, the fixed seat 20 is fixedly installed on the adjusting plate 22. Both sides of the adjusting plate 22 are slidably arranged on the first slide rail 101.

That is, the adjusting plate 22 is fixed to the frame 1 through the lead screw 23. In this way, the positions of the fixed seat 20 and the adjusting plate 22 on the frame 1 can be adjusted, and then fixed through the lead screw, so that it can be applicable to bolt sleeves of different lengths. A first mounting plate 24 is connected to the lower side of the adjusting plate 22. The second driving member 12 is fixed on the first mounting plate 24, and the second driving member 12 is connected to the first positioning sleeve 21 by belt drive. The position of the first driving member 11 is relatively fixed with respect to the fixed seat 20, which is convenient for adjustment. The movable seat 30 is fixedly installed on the sliding plate 32. Both sides of the sliding plate 32 are slidably arranged on the first slide rail 101. The first driving member 11 is fixed on the frame 1, and the output end of the first driving member 11 is fixedly connected to the movable seat 30.

[0033] As Figures 5 to 6As shown in the figure, the wire tensioning assembly 40 is arranged on one side of the support assembly 10. The wire tensioning assembly 40 includes a second slide rail 102 and a slide table 41. The second slide rail 102 is arranged in parallel with the first slide rail 101 on the frame 1. The slide table 41 is slidably arranged on the second slide rail 102. The driving device drives the slide table 42 to reciprocate on the second slide rail 102. An air-operated scissors 42 is arranged on the slide table 41. The air-operated scissors 42 can extend to the upper surface of the bolt sleeve 100 fixed on the support assembly 104. After the air-operated scissors 42 extends out and cuts off the fiberglass wire connected to the wire structure and the bolt sleeve 100, it retracts and resets. In this embodiment, the device 49 for driving the air-operated scissors 42 to reciprocate is preferably a cylinder.

Further, a wire clamping tensioner is arranged in front of the wire passing hole 47. The fiberglass wire reaches the bolt sleeve 100 through the wire passing hole 47. The slide table 41 drives the wire passing hole 74 to reciprocate while the bolt sleeve 100 rotates, so as to wind the fiberglass wire evenly around the bolt sleeve 100. A second wire clamping part 60 is arranged between the wire winding rollers 46 and the wire passing hole 47. A second tensioning part 5 is arranged at the rear side of the first tensioning part 4.

The wire winding roller is arranged between the second pulley and the second wire clamping part. The wire winding roller 46 is arranged between the second pulley 51 and the second wire clamping part 60. When the wire winding and knotting are completed, the second wire clamping part 60 presses the fiberglass wire to prevent the fiberglass wire on the first tensioning part 4 from being pulled. After the knotting is completed, the first tensioning part 4 retracts to tighten the knotted coil and tighten the fiberglass wire, so that the fiberglass wire is fixed on the bolt sleeve 100. The second wire clamping part 60 rises, and the first wire clamping part 50 presses the fiberglass wire tightly, and the pressing rod 55 moves downward to press the fiberglass wire between the first pulley 51 and the second pulley 52, further tightening the fiberglass wire.

[0035] In a preferred case, the first wire clamping part 50 includes a first fixing plate 53 and a first clamping plate 54 arranged vertically. The first fixing plate 53 and the first clamping plate 54 are arranged oppositely.

The second clamping plate 62 is connected with a fifth driving part 44, and the fifth driving part 44 is used to drive the second clamping plate 62 to move vertically to press the glass fiber yarn against the second fixing plate 61. The wire passing hole 47 is arranged vertically at one end of the second fixing plate 61. The lower side of one end of the pressure rod 55 is connected with a sixth driving part 45, and the sixth driving part 45 is used to drive the pressure rod 55 to move up and down. Further, wire passing rings 56 are arranged on the upper and lower sides of the first wire clamping part 50, and a wire guiding hole 57 is also arranged on the lower side of the lower wire passing ring 56. The wire passing rings 56 are used to prevent the glass fiber yarn from coming out of the first wire clamping part 50, and the wire guiding hole 57 is used to guide the opened glass fiber yarn on the coil to the lower side of the first wire clamping part 50.

[0036] In a preferred case, a tensioning slideway 63 is arranged on the sliding table 41. The bottom of the second fixing plate 61 is fixedly connected with a moving plate 64. The moving plate 64 is connected with a tensioning cylinder 48, and the tensioning cylinder 48 is used to drive the first tensioning part 4 to move on the tensioning slideway 63.

[0037] As Figures 7 to 12 shown, the knotting and winding component 70 is arranged on one side of the movable seat 30 of the supporting component 10. The knotting and winding component 70 includes a winding clamp 80, a knotting support rod 90 and a knotting clamp 2. The winding clamp 80 and the knotting support rod 90 can rotate relative to the axis of the second positioning sleeve 31 and can move along the axis of the second positioning sleeve 31. The knotting clamp 2 is arranged on one side of the supporting component 10 and cooperates with the knotting support rod 90 to pull the glass fiber yarn 200 to complete knotting.

[0038] After the winding clamp 80 clamps the end of the glass fiber yarn and moves forward to the middle of the bolt sleeve, the winding clamp 80 rotates clockwise around the axis of the second positioning sleeve 31 to wind the end of the glass fiber yarn around the bolt sleeve. Then the winding clamp 80 moves backward. The wire guiding and tensioning component 40 moves in the same direction as the winding clamp 80. At the same time, the bolt sleeve 100 rotates clockwise to wind the wire and press the end of the previously wound glass fiber yarn. The winding clamp 80 releases the clamped glass fiber yarn, and then the wire winding can start.

[0039] The knotting and winding component 70 includes a base 71 which is slidably arranged on the first slide rail 101. A support base 72 is fixedly provided on the base 71. A rotating shaft sleeve 73 is rotatably arranged on the support base 72.

The other end of the linkage plate 84 is hinged to a pull rod 85. The other end of the pull rod 85 is connected to a ninth driving member 75. The ninth driving member 75 drives the pull rod 85 to reciprocate. The pull rod 85 drives the movable clamp 83 to move through the linkage plate 84. Thus, the movable clamp 83 moves away from the fixed clamp 82 to open the winding clamp 80 to clamp the glass fiber yarn, or the movable clamp 83 moves close to the fixed clamp 82 to bite the winding clamp 80 to clamp the glass fiber yarn.

[0040] In a preferred case, the pull rod 85 is horizontally arranged on the clamp seat 81. The linkage plate 84 is vertically arranged on the clamp seat 82, and a sliding block 86 is arranged between the linkage plate 84 and the clamp seat 81. The sliding block 86, the linkage plate 84 and the pull rod 85 are hinged together through a triangular plate 861. When the pull rod 85 moves horizontally, the sliding block 86 and the linkage plate 84 move up and down, and the sliding block 86 and the linkage plate 84 limit each other to prevent tilting. Further, an avoidance groove 851 cooperating with the sliding block 86 is provided on the pull rod 85.

[0041] In a preferred case, an installation seat 87 is further provided on the base 71. A through hole 871 is provided in the middle of the installation seat 87. The rotating shaft sleeve 73 passes through the through hole 871. A ninth driving member 75 is fixedly connected to the installation seat 87. The output end of the ninth driving member 75 is connected to an arc-shaped sliding groove 88. The arc-shaped sliding groove 88 is coaxially arranged with the second positioning sleeve 31. A clamping plate 89 is provided at the end of the pull rod 85 away from the movable clamp 83. The clamping plate 89 is slidably clamped in the arc-shaped sliding groove 88. The ninth driving member 75 drives the arc-shaped sliding groove 88 to move along the axis of the second positioning sleeve 31, thereby driving the clamping plate 89 clamped in the arc-shaped sliding groove 88 to reciprocate, and further realizing the reciprocating movement of the pull rod 85, that is, realizing the opening or closing of the winding clamp. When the winding clamp 80 rotates, the clamping plate 89 slides in the arc-shaped sliding groove 88. Further, the middle of the pull rod 85 is hinged to the clamp seat 81.

[0042] In a preferred case, a third driving member 77 is provided on the base 71. The output end of the third driving member 77 is fixedly connected to the sliding plate 32, and the third driving member 77 drives the base 71 to slide on the first slide rail 101.

The first support rod 91 is arranged on one side of the clamping seat 81, and the first support rod 91 is height-matched with the fixed clamp 81. At this time, the fixed clamp 82 is used as the second support rod 92. After the wire winding is completed, the rotating shaft sleeve 73 drives the knotting support rod 90 to move to the vicinity of the fiberglass wire between the wire passing hole 47 and the bolt sleeve 100. Rotate the knotting support rod 90 clockwise to wind the fiberglass wire around the first support rod 91 and the second support rod 92 to form a knotting loop. Move the wire guiding and tensioning assembly 40 so that the fiberglass wire between the wire passing hole 47 and the bolt sleeve 100 misses the first support rod 91 and obliquely passes through the knotting loop. The knotting clamp 2 extends and passes through the knotting loop from inside the knotting loop to clamp the fiberglass wire. Then the knotting clamp 2 retracts to pull the fiberglass wire through the knotting loop, and the knotting clamp 2 drives the fiberglass wire to rise and cross over the knotting loop from the outside of the knotting loop to facilitate knotting. The knotting support rod 90 resets and retracts from the knotting loop. The second wire clamping part 60 presses down to clamp the fiberglass wire. Rotate the bolt sleeve 100 to tighten the knotting loop and wind it around the bolt sleeve 100 to form a knot, and at the same time, it can also make the two crossing points of the knotting loop and the fiberglass wire move away from each other. Then the knotting clamp 2 releases the fiberglass wire and resets and retracts. The second wire clamping part 60 retracts to tighten the fiberglass wire pulled up by the knotting clamp 2 to complete the knotting. Then the second wire clamping part 60 rises to release the fiberglass wire. The first wire clamping part 50 clamps the fiberglass wire, and the pressing rod 55 moves downward to further tighten the fiberglass wire. The second wire clamping part 60 presses down again to clamp the fiberglass wire. The wire winding clamp 80 rotates counterclockwise to make the fixed clamp 82 pick and press the fiberglass wire to facilitate the moving clamp 83 to lift and close to clamp the fiberglass wire. Then the pneumatic scissors 42 extend to cut the fiberglass wire between the wire winding clamp 80 and the bolt sleeve 100 and then reset to complete the wire winding.

A storage space is provided on the lower side of the frame 1. The coil 210 of glass fiber yarn is placed in the storage space, and the glass fiber yarn released from the coil 210 passes through the discharge port 103 and then enters the wire guiding hole 57.

[0047] In a preferred case, the first driving member, the third driving member, the fourth driving member, the fifth driving member, the sixth driving member, the seventh driving member, and the ninth driving member are preferably cylinders, and the second driving member and the eighth driving member are preferably servo motors.

[0048] To better illustrate the working method of the present invention, the working steps of the automatic wire winding machine for the bolt sleeve of a wind turbine blade are as follows:

[0049] (1) The end of the glass fiber yarn sequentially passes through the wire guiding hole 57, the wire threading loop 56, and the first wire clamping part 50, then bypasses above the first pulley 51 and the second pulley 52, and after being guided by the wire winding roller 46, passes through the second wire clamping part 60 and the wire passing hole 47, and is clamped by the wire winding clamp 80.

[0050] (2) The bolt sleeve 100 is placed on the positioning blocks 302 of the feeding component 3. The feeding component 3 drives the bolt sleeve 100 to rise to be coaxial with the support component 10. The first driving member 11 drives the movable seat 30 to approach the fixed seat 20, and the bolt sleeve 100 is tightly pressed and fixed between the first positioning sleeve 21 and the second positioning sleeve 31.

[0051] (3) The third driving member 77 drives the wire winding clamp 80 to move to the middle of the bolt sleeve 100. The eighth driving member 74 drives the wire winding clamp 80 to rotate clockwise, and the end of the glass fiber yarn is wound around the bolt sleeve 100.

[0052] (4) The wire winding clamp 80 retracts, and the wire guiding and tensioning component 40 moves in the same direction. At the same time, the second driving member 12 drives the bolt sleeve 100 to rotate clockwise for wire winding to press the previously wound glass fiber yarn. The wire winding clamp 80 releases the glass fiber yarn and resets.

[0053] (5) The second driving member 12 drives the bolt sleeve 100 to rotate rapidly for wire winding. The wire guiding and tensioning assembly 40 reciprocates on the second slide rail 102 for wire feeding, and evenly winds the fiberglass wire around the entire surface of the bolt sleeve 100;

[0054] (6) After the wire winding is completed, the bolt sleeve 100 stops rotating, and the wire guiding and tensioning assembly 40 stops at the middle position of the bolt sleeve 100;

[0055] (7) The third driving member 77 drives the knotting support rod 90 to move to the middle of the bolt sleeve 100, and the eighth driving member 74 drives the knotting support rod 90 to rotate clockwise, so that the fiberglass wire winds around the first support rod 91 and the second support rod 92 to form a knotting loop;

[0056] (8) Move the wire guiding and tensioning assembly 40 so that the fiberglass wire between the wire passing hole 47 and the bolt sleeve 100 misses the first support rod 91 and obliquely passes through the knotting loop;

[0057] (9) The knotting clamp 2 extends and passes through the knotting loop to clamp the fiberglass wire 200. Then the knotting clamp 2 retracts to pull the fiberglass wire 200 through the knotting loop, and the knotting clamp 2 drives the fiberglass wire to rise and cross over the knotting loop from the outside of the knotting loop for convenient knotting;

[0058] (10) The knotting support rod 90 resets and retracts from the knotting loop, the second wire clamping part 60 presses down to clamp the fiberglass wire, and the bolt sleeve 100 is rotated to tighten the knotting loop and wind it around the bolt sleeve 100 to form a knot;

[0059] (11) The knotting clamp 2 releases the fiberglass wire 200 and resets and retracts. The tensioning cylinder 48 drives the first tensioning part 4 to slide backward on the tensioning slide rail 63, so that the fiberglass wire 200 retracts to tighten the knot, and the second wire clamping part 60 rises;

[0060] (12) The first wire clamping part 50 clamps the fiberglass wire, and the pressing rod 55 moves downward to further tighten the fiberglass wire 200, completing the knotting.

[0061] (13) The second wire clamping part 60 presses down again to clamp the fiberglass wire, and the winding clamp 80 rotates counterclockwise, so that the fixed clamp 82 picks and presses the fiberglass wire to the lower side of the fixed clamp 82, and the moving clamp 83 rises and closes to clamp the fiberglass wire;

[0062] (14) The first clamping plate 54 of the first wire clamping part 50 resets to release the fiberglass wire, and at the same time the pressing rod 55 moves upward to reset. The second clamping plate 62 of the second wire clamping part 6 rises to reset and release the fiberglass wire;

[0063] (15) The pneumatic scissors 42 extend to cut the fiberglass wire 200 between the winding clamp 80 and the bolt sleeve 100 and then reset, completing the wire winding; the tensioning cylinder 48 drives the first tensioning part 4 to slide forward on the tensioning slide rail 63 to reset.

[0064] (16) Repeat the process in (2) to (15) above to wind the wire for the next bolt.

[0065] The above embodiments are only several descriptions of the concept and implementation of the present utility model, and do not limit it. Under the concept of the present utility model, technical solutions without substantial transformation are still within the protection scope.
