Description

TECHNICAL FIELD

[0001] The present invention relates to the field of wind turbine blades, and particularly relates to a mobile quick adhesive dispensing method for a wind turbine blade moulded by a large mould.BACKGROUND

[0002] A series of new energy industries represented by the wind power industry face industry challenges in cycle time reduction and efficiency improvement, especially in the production of wind turbine blades. Manufactured wind turbine blades on the market have varying lengths, which have reached and exceeded 100 meters, and simultaneously, the volume of adhesives dispensed increases, thereby causing longer adhesive dispensing time and reduction of production efficiency and influencing the quality of products because of curing risks caused by too much time for adhesive dispensing in the blade making process.

[0003] In the prior art, wind turbine blades are bonded with adhesives in a fixed-point manner. Equipment conveys mixed adhesives onto paper boards or into basins according to the required weight, and workers transfer the adhesives to designated places manually. In this transport process, a great deal of manpower is consumed while the mixed adhesives may be cured to produce lots of solid wastes, which would have an adverse effect on the environment and cause a great loss of materials. In many cases, an adhesive dispensing procedure is not completed yet on part of areas of a wind turbine blade while some places the adhesives have been cured, thereby causing a reduction of production efficiency and extremely unstable quality of products. Besides, an adhesive dispensing system is separated from two sides of an adhesive dispensing head, thereby causing poor adhesive dispensing efficiency due to a lack of coordination between the adhesive dispensing system and the adhesive dispensing head in the adhesive dispensing process.

[0004] For example, an automatic positioning wind turbine blade adhesive dispensing device and adhesive dispensing method disclosed in CN 114289269 B, comprising positioning guide rails, a power driven moving platform and an adhesive dispensing tool arranged on the power driven moving platform and synchronously moving along with the power driven moving platform, the positioning guide rails are arranged on both sides of front and back edges of a main blade mould, installation positions of the positioning guide rails are determined based on a parting line of the front and back edges of the main blade mould as a positioning standard in conjunction with positioning data of webs in a blade so that the shape of the positioning guide rail on each side is the same as that of a stream line on one corresponding side of the blade; the adhesive dispensing tool, the power driven moving platform and the positioning guide rails in a specific shape are integrated into an automatic positioning wind turbine blade adhesive dispensing device, which can implement accurate positioning and adhesive dispensing, solve the problems of uneven manual adhesive dispensing effects and large positional deviation, eliminate bonding defects caused by positioning deviation and improve quality of products. At the same time, the device can implement synchronous and automated adhesive dispensing on bonding regions of webs on the front and back edges and improve operational efficiency. However, in the actual operation process, wind turbine blades have large sizes, and the volume of adhesives dispensed is large, so the adhesive supplementation process is complicated, and part of adhesive dispensed areas of the wind turbine blade has been cured while part of areas of the wind turbine blade are not coated with adhesives. Moreover, the structure is high in cost and not suitable for various types of mould.

[0005] For another example, a device and method for automatically positioning adhesive dispensing positions of a wind turbine blade in the adhesive dispensing process disclosed in the Chinese patent CN 115646764 A belong to the field of wind turbine blade adhesive dispensing technology. The device comprises a wall-mounted track, a cross beam, an adhesive dispensing device and a follow-up carrying trolley, the wall-mounted track is mounted on an I-beam of a stand column in a production workshop of a factory and is divided into an upper track and a lower track, the upper track and the lower track are respectively provided with an upper square tube and a lower square tube, and the upper square tube and the lower square tube together support a cross beam walking component; the cross beam comprises a cross beam main body and the cross beam walking component, and the cross beam walking component is connected to the cross beam main body through a rotating shaft; the cross beam provides supporting and guiding for the adhesive dispensing device; the adhesive dispensing device comprises a waling servo hoist, a balancer and a rubber boot and is suspended onto the cross beam main body; and the follow-up carrying trolley is used for carrying an adhesive dispensing system and control system hardware. The present invention can meet the demands of different adhesive dispensing areas of blades for adhesive dispensing processes and improve the adhesive dispensing operation efficiency and quality. The adhesive dispensing device in this structure is high in cost and not suitable for various types of mould, and also has a problem of low adhesive dispensing speeds, so the adhesive supplementation process is complicated, part of adhesive dispensed areas of a wind turbine blade have been cured while part of areas are not coated with adhesives and the working efficiency is low.

[0006] Document CN 115 999 841 discloses an integrated refined gluing device and method for wind power blade manufacturing, in which a coordinated system of structural supports, rails, beams and gluing assemblies enables systematized and data-driven precise gluing by collecting and matching position and adhesive information during operation.SUMMARY

Step 6, receding from a turning arm when the turning arm is required to join the two halves of the large wind turbine blade mould, sending, by the PLC circuit, signals to the heavy-duty guided vehicle to allow the heavy-duty guided vehicle to move to an initial specified position, sending, by the PLC circuit, signals to air pumps to stop the air pumps from feeding gas into a left air cylinder and a right air cylinder, so that piston rods of the left air cylinder and the right air cylinder return to the insides of pistons, thereby allowing a Left receding mechanism and a Right receding mechanism to be disconnected under the action of the left air cylinder and the right air cylinder, wherein a disconnected distance between the Left receding mechanism and the Right receding mechanism is a width required for the turning of the turning arm; When the turning arm completes the joining of the two halves of the large wind turbine blade mould, sending, by the PLC circuit, signals to the air pumps to allow the piston rods of the left air cylinder and the right air cylinder to be pushed out to push the Left receding mechanism and the Right receding mechanism upward respectively, so that the Left receding mechanism and the Right receding mechanism are respectively connected to the two adjacent high-capacity adhesive mixer rail systems to allow the heavy-duty guided vehicle loaded with the high-capacity adhesive mixer to go into a space between the Left receding mechanism and the Right receding mechanism from the high-capacity adhesive mixer rail system, subsequently go into the next high-capacity adhesive mixer rail system and finally arrive at the guided vehicle bearing platform located at one end of the frontmost high-capacity adhesive mixer rail system; Step 7, landing of the high-capacity adhesive mixers sending, by the PLC circuit, signals to the driving motors to allow the driving motors to rotate anticlockwise to drive the self-locking screws connected thereto to rotate clockwise, so that the guided vehicle bearing platform horizontally and gradually moves downward to a specified position, sending, by the position sensors located on the frame mechanisms, signals to the PLC circuit, when the guided vehicle bearing platform moves downward to the specified position, sending, by the PLC circuit, rotating stop signals to the driving motors to allow the heavy-duty guided vehicle to land on the ground, and repeating the above actions until all the heavy-duty guided vehicles land on the ground;
