Description

Technical Field

[0001] This invention relates to the field of molding technology in the production of wind turbine blades, and particularly to an automated feeding device for a sheet uncoiling frame used in the plastic processing of fiber pultruded sheets. Background Technology

[0002] As is well known, to maximize power generation, the length and swept air volume of wind turbine blades are increasing daily, resulting in an increase in blade weight. To overcome this challenge, the blade manufacturing process in the wind power industry is constantly being innovated. The presence of the main beam in the wind turbine blade increases the overall strength of the blade and also ensures its toughness, flexibility, and bending resistance. However, the weight of the main beam itself cannot be ignored. To reduce the blade's weight while increasing its overall strength, the traditional cast-in-place beam has been replaced by the current pultruded beam. To better integrate the pultruded plates into the blade, further processing and shaping are required.

[0003] The post-processing equipment for pultruded beams developed and manufactured both domestically and internationally all employ a semi-automatic, manual intervention method. Currently, the operation is as follows: the uncoiling process is entirely manual. Workers hoist the pultruded coil to the uncoiling frame, manually install it onto the frame, and then use mechanical rotation of the tensioning components to install and tighten the pultruded coil. The binding tape on the coil is then manually cut. Each uncoiling operation requires a dedicated person; one person must be assigned to this workstation. Furthermore, manual uncoiling at this station carries the risk of uneven uncoiling, inadequate tensioning after uncoiling, and instability, potentially leading to coil bursting due to unstable tension or insufficient compaction of the coil exit before cutting the binding tape. Simultaneously, the labor intensity is high, and the work efficiency is unsatisfactory. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of existing devices. This invention provides an automated feeding device for uncoiling sheet for plastic processing of fiber pultruded sheets.

[0005] This invention is achieved through the following technical solution:

[0006] An automated feeding device for uncoiling pultruded sheets in plastic processing includes a storage and adjustment platform and an uncoiling frame mechanism. The storage and adjustment platform includes a support base plate, a grooved strip support platform, and a robotic arm. The grooved strip support platform is disposed on the support base plate and is used to store the pultruded coil to be processed. The robotic arm is used to slide and move the pultruded coil from the grooved strip support platform to the uncoiling frame mechanism. The uncoiling frame mechanism includes a support platform base, a tensioning mechanism moving bottom slide rail assembly, an uncoiling drive disc drive motor assembly, a toothed drive disc, multiple screw tensioning mechanisms, and multiple L-shaped tensioning metal blocks. The multiple screw tensioning mechanisms... All mechanisms are connected to the edge tooth transmission disk. Multiple L-shaped tensioning metal blocks correspond one-to-one with multiple screw tensioning mechanisms. One end of each L-shaped tensioning metal block is connected to the screw tensioning mechanism. The tensioning mechanism's moving bottom slide rail assembly acts on the L-shaped tensioning metal block, causing the other end of the L-shaped tensioning metal block to extend into the inner hole of the pultruded coil. The uncoiling drive disc drive motor assembly is connected to the edge tooth transmission disk and is used to drive the rotation of the edge tooth transmission disk and synchronously drive the rotation of the multiple screw tensioning mechanisms, so that the movement of the L-shaped tensioning metal blocks achieves the tensioning and unwinding actions of the pultruded coil.

[0007] Furthermore, the robotic arm includes a first five-axis robotic arm and a robotic arm mounting base. The robotic arm mounting base is used to fix the robotic arm to the ground. The first five-axis robotic arm is connected to the robotic arm mounting base. The first five-axis robotic arm is used to slide the pultruded coil from the grooved strip support platform to the uncoiling frame mechanism, and to clamp the pultruded coil on the pallet and place it on the grooved strip support platform.

[0008] Furthermore, the storage and adjustment platform also includes a first slide rail assembly, which is connected to the bottom of the bearing base plate and is used to drive the movement of the bearing base plate so that the groove-shaped strip bearing platform matches the corresponding feeding docking position on the uncoiling frame mechanism.

[0009] Furthermore, the uncoiling frame mechanism also includes a second slide rail assembly, which is connected to the bottom of the support platform base and is used to drive the movement of the support platform base.

[0010] Furthermore, each of the toothed drive discs has four lead screw tensioning mechanisms, which are respectively located at the four positions of the toothed drive disc.

[0011] Furthermore, the uncoiling frame mechanism also includes a pneumatic lifting and braking device. The pneumatic lifting and braking device and the storage and adjustment platform are located on both sides of the screw tensioning mechanism. The bottom of the pneumatic lifting and braking device is connected to the base of the bearing platform, and the top of the pneumatic lifting and braking device is used to abut against the pultruded coil to brake and stop the rotation of the pultruded coil.

[0012] Furthermore, the pneumatic lifting and braking device includes a telescopic pneumatic component and a rigid rubber material. The bottom of the telescopic pneumatic component is connected to the base of the support platform, and the top of the telescopic pneumatic component is connected to the rigid rubber material. The rigid rubber material abuts against the pultruded coil.

[0013] Furthermore, the uncoiling mechanism also includes a second five-axis robotic arm, which is connected to the support platform base and is used to remove the binding straps from the pultruded coil.

[0014] Furthermore, the storage and adjustment platform also includes a pneumatic lifting stop, which can extend into the trough-shaped support platform or retract outside the trough-shaped support platform.

[0015] Furthermore, the automated feeding device for uncoiling sheet for plastic processing of fiber pultruded sheet also includes an outer frame, which covers the uncoiling frame mechanism.

[0016] The beneficial effects of this invention are as follows:

[0017] The automated feeding device for pultruded sheet uncoiling in this invention will realize automatic feeding and uncoiling of pultruded sheets without human intervention, completely changing the drawbacks of previous manual assistance and laying a solid foundation for automated production. It also avoids the risk of accidents during manual operation and improves production efficiency. Attached Figure Description

[0042] 29 Second five-axis robotic arm Detailed Implementation

[0043] The following description of the embodiments is taken with reference to the accompanying drawings, which illustrate specific embodiments in which the invention can be implemented.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment discloses an automated feeding device for uncoiling sheet plastic processing of fiber pultruded sheets. The automated feeding device for uncoiling sheet plastic processing of fiber pultruded sheets includes a storage and adjustment platform 1 and an uncoiling mechanism 2. The storage and adjustment platform 1 includes a support base plate 11, a grooved strip support platform 12 and a robot arm 13. The grooved strip support platform 12 is disposed on the support base plate 11 and is used to store the pultruded coil to be processed. The robot arm 13 is used to slide and move the pultruded coil from the grooved strip support platform 12 to the uncoiling mechanism 2.

[0045] In this embodiment, the supporting base plate 11 is a square metal base with a length of 2700mm, a width of 1600mm, and a thickness of 30mm. Ten sets of grooved strip-shaped supporting platforms 12 with moving and sliding rail devices are installed on it. The grooved strip-shaped supporting platform 12 can simultaneously support and hold 10 rolls of pultruded sheet with a diameter of 2800mm, a width of 120mm, and an inner diameter of 1550mm. The grooved strip-shaped supporting platform 12 is designed with ten grooved strip-shaped supporting platforms with a length of 2000mm, a width of 130mm, a height of 200mm, and a single-sided thickness of 10mm. The grooved strip-shaped supporting platform 12 always stores the pultruded rolls to be processed. The robot arm 13 mainly performs the functions of handling, pushing, and stabilizing the sheet.

[0046] The uncoiling frame mechanism 2 includes a support platform base 21, a tensioning mechanism moving bottom slide rail assembly 22, an uncoiling drive disc drive motor assembly 23, a toothed drive disc 24, multiple screw tensioning mechanisms 25, and multiple L-shaped tensioning metal blocks 26. The multiple screw tensioning mechanisms 25 are all connected to the toothed drive disc 24. The multiple L-shaped tensioning metal blocks 26 correspond one-to-one with the multiple screw tensioning mechanisms 25. One end of the L-shaped tensioning metal block 26 is connected to the screw tensioning mechanism 25. The tensioning mechanism moving bottom slide rail assembly 22 acts on the L-shaped tensioning metal block 26 so that the other end of the L-shaped tensioning metal block 26 extends into the inner hole of the pultruded coil. The uncoiling drive disc drive motor assembly 23 is connected to the toothed drive disc 24 and is used to drive the rotation of the toothed drive disc 24 and synchronously drive the rotation of the multiple screw tensioning mechanisms 25, so that the movement of the L-shaped tensioning metal blocks 26 realizes the tensioning and unwinding action of the pultruded coil.

[0047] The support platform base 21 is the mounting base plate used to support the entire uncoiling frame mechanism 2. After the pultruded coil to be processed is placed on the grooved strip support platform 12 and enters the designated position of the uncoiling frame mechanism 2, the motor on the tensioning mechanism moving bottom slide rail assembly 22 runs, driving the gear installed on the motor. The gear runs forward on the rack and stops after reaching the set position. At this time, the L-shaped tensioning metal block 26 on the tensioning plate moves forward under the force of the tensioning mechanism moving bottom slide rail assembly 22, so that the L-shaped tensioning metal block 26 enters the inner hole of the pultruded coil. Because the forward stroke set by the program just exceeds the width value of the pultruded coil to be processed, it ensures that the L-shaped tensioning metal block 26 smoothly exceeds the width value. Then the screw tensioning mechanism 25 runs, so that the screw tensioning mechanism 25 drives the L-shaped tensioning metal block 26 to move in the opposite direction (outward), completing the tensioning work of the pultruded coil.

[0048] The uncoiling drive disc motor assembly 23 is connected to the edge gear drive disc 24. When the uncoiling drive disc motor assembly 23 starts working, it will directly drive the edge gear drive disc 24 to rotate. Powered by the uncoiling drive disc motor assembly 23, it can achieve stepless speed regulation according to the main control and program control of the equipment, and can also perform forward and reverse rotation.

[0049] In this embodiment, each toothed drive disc 24 has four lead screw tensioning mechanisms 25, which are respectively located at the four positions of the toothed drive disc 24. The lead screw tensioning mechanism 25 is designed and manufactured by imitating the internal structure of the lathe headstock. The four lead screw tensioning mechanisms 25 are controlled by a set of geared motors. The rotating shaft of the geared motor is designed to be installed on the main shaft core of the four lead screw tensioning mechanisms 25. When the geared motor rotates, it drives the rotating structure behind the lead screw tensioning mechanism 25 and designed to be installed inside the disc. The rotating structure can synchronously drive the rotation of the four lead screw tensioning mechanisms 25, thereby driving the L-shaped tensioning metal block 26 designed to be installed on the lead screw. The L-shaped tensioning metal block 26 moves up and down on the toothed drive disc 24, thereby realizing the tensioning and loosening of the pultruded coil.

[0050] In this embodiment, the L-shaped tensioning metal block 26 is designed and assembled on the screw tensioning mechanism 25. When the screw tensioning mechanism 25 rotates in the forward or reverse direction, it drives the L-shaped tensioning metal block 26 to move upward or downward. At the same time, when the L-shaped tensioning metal block 26 moves upward, it completes the work of supporting and tensioning the inner diameter of the pultruded sheet roll. When the L-shaped tensioning metal block 26 moves downward, it loosens the already tensioned pultruded roll.

[0051] Compared with existing technologies, the automated feeding device for pultruded sheet uncoiling in this embodiment fully automates the feeding and uncoiling processes of pultruded sheets. It replaces the conventional method of using a cantilever crane to lift and feed the pultruded sheets with a robotic arm 13 that automatically clamps the roll into a specially designed structural component. Through automatic program control, the roll is automatically transported to the designated position on the uncoiling mechanism 2. This not only ensures consistent and accurate positioning of the roll during feeding but also achieves unmanned automated operation. Furthermore, the automated method is faster, more precise in feeding position, and more accurate in controlling the internal tension of the roll after feeding. This completely avoids the unpredictable and serious consequences such as roll bursting or damage caused by the uncertainty of tension due to manual mechanical tensioning of pultruded sheets. At the same time, it lays a solid foundation for the automation of the entire pultruded sheet processing equipment. This system enables automated loading and unwinding of pultruded coils without any human intervention, completely eliminating the drawbacks of traditional manual assistance and laying a significant foundation for automated production. It also mitigates the risks of accidents that can occur during manual operations, thereby improving production efficiency.

[0052] The robotic arm 13 includes a first five-axis robotic arm 131 and a robotic arm mounting base 132. The robotic arm mounting base 132 is used to fix the robotic arm 131 to the ground. The first five-axis robotic arm 131 is connected to the robotic arm mounting base 132 and is used to slide the pultruded coil from the channel-shaped strip support platform 12 to the uncoiling frame mechanism 2, and to clamp and place the pultruded coil on the pallet onto the channel-shaped strip support platform 12.

[0053] Specifically, the robotic arm mounting base 132 is directly fixed to the ground using expansion bolts, the number of which depends on the actual situation. The robotic arm mounting base 132 is installed on the right side of the support base plate 11, with the specific installation position and distance determined by the working radius of the first five-axis robotic arm 131 and the actual application requirements of this scenario. The first five-axis robotic arm 131 is mainly used for assisting in the sliding and lateral movement of coiled material from the storage and adjustment platform 11 to the uncoiling frame mechanism 2. It also clamps and places pultruded coiled material from the pallet onto the trough-shaped support platform 12, preparing it for the next material loading cycle. The first five-axis robotic arm 131 will perform various tasks such as moving, pushing, lifting, and transferring pultruded sheets from the pallet onto the trough-shaped support platform 12. The first five-axis robotic arm 131 is a mature standard product, with its control program integrated with the host computer.

[0054] The storage and adjustment platform 1 also includes a first slide rail assembly 14, which is connected to the bottom of the supporting base plate 11 and used to drive the movement of the supporting base plate 11 so that the trough-shaped strip supporting platform 12 matches the corresponding feeding docking position on the uncoiling frame mechanism 2. By designing and installing the first slide rail assembly 14 at the bottom of the supporting base plate 11, the supporting base plate 11 can move back and forth, so that the trough-shaped strip supporting platform 12 matches the corresponding feeding docking position on the uncoiling frame mechanism 2, and the pultruded coil in the trough-shaped strip supporting platform 12 can be smoothly moved laterally into the feeding position on the uncoiling frame mechanism 2.

[0055] The uncoiling frame mechanism 2 also includes a second slide rail assembly 27, which is connected to the bottom of the support platform base 21 and is used to drive the movement of the support platform base 21. By designing and installing the second slide rail assembly 27 at the bottom of the support platform base 21, the forward and backward movement function of the support platform base 21 is realized. The second slide rail assembly 27 together completes the function of precise forward and backward movement of the support platform base 21 and all the uncoiling frame mechanisms 2 on it under the pre-set program, thereby completing the uncoiling and feeding of pultruded sheet by the uncoiling frame mechanism 2.

[0056] The first slide rail assembly 14 and the second slide rail assembly 27 each include two slide rail assemblies. Each slide rail assembly consists of a gear and rack system, a transmission motor assembly, a guide rail, and a corresponding slider. The movement of the first slide rail assembly 14 and the second slide rail assembly 27 is powered by a 2.5KW servo motor, and the conversion of output power into movement is achieved through gear and rack transmission. A metal locating pin is designed and installed on each end face of the two slide rail assemblies as a safety protection device to prevent the movable platform above it from overshooting during lateral movement.

[0057] The storage and adjustment platform 1 also includes a pneumatic lifting stop 15, which can extend into or retract out of the channel-shaped strip support platform 12. A set of pneumatic lifting stops 15 is designed and installed on the left end face of each channel-shaped strip supporting the pultruded sheet in the channel-shaped strip support platform 12. When fully extended or retracted, the pneumatic lifting stops 15 extend into the channel to prevent the pultruded sheet from moving or rolling, thus preventing the pultruded coil from rolling back and forth without damaging the coil itself. When fully retracted, the pneumatic lifting stops 15 are activated, so that the highest point of the pneumatic lifting stops 15 is lower than the bottom surface of the channel-shaped strip support platform 12, thereby ensuring that the pultruded coil can smoothly move to the next process and complete subsequent work.

[0058] The storage and adjustment platform 1 also includes a baffle 16, which is installed on the support base plate 11 and located between the channel-shaped support platform 12 and the robot arm 13. The baffle 16 acts as a barrier for the pultruded coil on the channel-shaped support platform 12, effectively preventing the pultruded coil from swaying back and forth or shifting in position within the channel-shaped support platform 12.

[0059] The trough-shaped strip support platform 12 constantly stores pultruded coils to be processed. A pneumatic telescopic cylinder can be designed and installed below the trough-shaped strip support platform 12 to provide driving force. The pneumatic telescopic cylinder drives the trough-shaped strip support platform 12 to move laterally towards the uncoiling frame mechanism 2. The pneumatic telescopic cylinder enables the trough-shaped strip support platform 12 to move left and right. The trough-shaped strip support platform 12 can be moved to the front of the uncoiling frame mechanism 2, and the four L-shaped tensioning metal blocks 26 can be smoothly extended into the inner hole of the pultruded sheet roll when fully retracted. After the pultruded coil on the trough-shaped strip support platform 12 is lifted after being tensioned by the L-shaped tensioning metal blocks 26 and completely detached from the trough-shaped strip support platform 12, the pneumatic telescopic cylinder smoothly retracts the trough-shaped strip support platform 12 and returns it to the starting position of the storage and adjustment platform 1, thereby realizing a reciprocating operation mode.

[0060] The uncoiling mechanism 2 also includes a pneumatic lifting and braking device 28. The pneumatic lifting and braking device 28 and the storage and adjustment platform 1 are located on both sides of the screw tensioning mechanism 25. The bottom of the pneumatic lifting and braking device 28 is connected to the support platform base 21, and the top of the pneumatic lifting and braking device 28 is used to abut against the pultruded coil to brake and stop the rotation of the pultruded coil. The pneumatic lifting and braking device 28 is installed on the left end face of the support platform base 21. After being lifted, the pneumatic lifting and braking device 28 will directly contact the width surface of the pultruded coil to brake and stop the rotation of the pultruded coil. At the same time, it can also lift and squeeze the discharge plate of the pultruded coil outlet to ensure that the pultruded coil does not loosen or burst.

[0061] The pneumatic lifting and braking device 28 includes a telescopic pneumatic component 281 and a rigid rubber material 282. The bottom of the telescopic pneumatic component 281 is connected to the base 21 of the support platform, and the top of the telescopic pneumatic component 281 is connected to the rigid rubber material 282. The rigid rubber material 282 abuts against the pultruded coil. The telescopic pneumatic component 281 is responsible for the telescopic operation. The rigid rubber material 282 has a triangular cross-sectional shape. The telescopic pneumatic component 281 applies force to the rigid rubber material 282 and initiates direct contact between the side of the rigid rubber material 282 and the width surface of the pultruded coil. The side of the rigid rubber material 282 is a conformal surface with a rounded arc. The purpose is to conform to the outer curved surface of the pultruded sheet, so that during the lifting and damping action, the contact area between the rigid rubber material 282 and the pultruded coil is larger, which can more efficiently realize the damping action and avoid frictional damage to the pultruded sheet.

[0062] The uncoiling mechanism 2 also includes a second five-axis robotic arm 29, which is connected to the support platform base 21 and used to remove the strapping tape from the pultruded coil. A second five-axis robotic arm 29 is designed and installed on the outer right side of the edge gear drive disc 24. This second five-axis robotic arm 29 will cut and remove the strapping tape binding the pultruded sheet, and clamp the removed strapping tape into a designated recycling bin. This second five-axis robotic arm 29 can also be programmed with other functions (other functions are pending expansion).

[0063] The automated feeding device for uncoiling sheet assemblies used in the plastic processing of fiber pultruded sheets also includes an outer frame, which covers the uncoiling frame mechanism 2. The outer frame encloses the uncoiling frame mechanism 2, thereby providing safety protection for it. The outer frame can be constructed from aluminum profiles.

[0064] In this embodiment, a support platform base 21 with a length of 2800mm, a width of 1800mm, and a height and thickness of 20mm is designed and installed on the left side of the groove-shaped support platform 12. Two sets of slide rail assemblies are designed and installed below the support platform base 21, which can realize the support platform base 21 to slide in the front and back directions. Two independent rectangular metal blocks are installed on the support platform base 21. A set of unwinding drive disc drive motor assemblies 23 are installed on each of the two identical rectangular metal blocks. A toothed drive disc 24 is mounted on the unwinding drive disc drive motor assembly 23. One side of the toothed drive disc 24 (facing the external operating surface) is machined with a lead screw tensioning mechanism 25, divided into four equal parts in the radial direction, each with a thickness of 80mm and a depth of 25mm. Each of the four equally divided lead screw tensioning mechanisms 25 has an L-shaped tensioning metal block 26. The L-shaped tensioning metal block 26 is connected to the lead screw tensioning mechanism 25 with a length of 135mm, a thickness of 20mm, and a width of 100mm. The other end of the L-shaped tensioning metal block 26 has a length of 120mm, a width of 100mm, and a thickness of 20mm. On the other side of the toothed drive disc 24, a full-disc equally divided toothed groove with a thickness of 50mm and a tooth pitch of 73mm is machined. This toothed groove is machined across the entire disc. The lifting and tightening of the L-shaped tensioning metal block 26 is accomplished by a 1.5KW servo motor and a reduction gear.

[0065] When applying the automated feeding device for uncoiling sheet in the plastic processing of fiber pultruded sheets according to this embodiment, the method includes the following steps:

[0066] (1) Hoist the correct pultruded sheet in the work area onto the trough-shaped strip bearing platform 12, and open the rolling device (rolling limit lifting cylinder and rod mechanical crossbar) at both ends of the trough-shaped strip bearing platform 12;

[0067] (2) The host control storage and adjustment platform 1 is reset at the origin and confirmed;

[0068] (3) Open the door of the outer frame, retract the L-shaped tensioning metal block 26, and ensure that the L-shaped tensioning metal block 26 is lowered to the lowest position on the tensioning plate;

[0069] (4) Start the robot arm 13 on the right side of the storage and adjustment platform 1 and clamp it on the pultruded sheet material to be fed into the uncoiling frame mechanism 2; and clamp the pultruded sheet material throughout the process of the sheet material entering the uncoiling frame mechanism to ensure that it is safely and stably fed into the designated position in the uncoiling frame mechanism 2; after the conveying action is completed, the robot arm 13 will retract to the initial state.

[0070] (5) Open the pneumatic telescopic cylinder below the grooved strip bearing platform 12 and lift it onto the uncoiling frame mechanism 2;

[0071] (6) Start the tensioning device to lower the support seat and make the support seat move forward towards the working surface (the termination position of the forward movement is set in advance by the program);

[0072] (7) After the L-shaped tensioning metal block 26 on the tensioning plate reaches the designated position in the inner hole of the pultruded sheet roll (one end of the L-shaped tensioning metal block 26 connected to the screw tensioning mechanism 25 completely exceeds the thickness of the inner wall of the pultruded sheet roll), the four screw tensioning mechanisms 25 on the tensioning plate are started and linked with the L-shaped tensioning metal block 26 to complete the action of being lifted by the L-shaped tensioning metal block 26 on the tensioning plate and the tensioning action of the pultruded sheet;

[0073] (8) Retract the grooved strip bearing platform 12 to the starting position;

[0074] (9) Open and lift the telescopic pneumatic component 281, the hard rubber material 282 at the discharge port of the pultruded sheet, and complete the lifting damping and pressing work of the discharge position of the pultruded sheet. Its action is to ensure that the sheet will not explode after the binding strap on the roll is completely cut.

[0075] (10) Start the second five-axis robotic arm 29 and complete its work of cutting and removing the strapping of the pultruded sheet that is stretched on the uncoiling frame;

[0076] (11) Turn on and rotate the tensioning plate to allow the pultruded sheet to pass through the discharge unwinding damping block at low speed and be slowly guided to the next station. When the pultruded sheet is transmitted from between the hard rubber materials 282, the system program will control the lifting and pressing force of the damping block on the pultruded sheet roll to ensure that the sheet is output at a constant speed while being slow and safe without unwinding.

[0077] (12) Repeat the above steps until the task is completed.

[0078] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
