Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind power blades, in particular to a large-mold forming wind power blade mobile rapid gluing method. BACKGROUND

[0002] A series of new energy industries represented by wind power are facing the industry problem of speeding up and increasing efficiency. In particular, in the production of wind power blades, the market produces wind power blades of various lengths, and the length of the blades has reached more than 100 meters. The amount of glue used for gluing is also increasing, resulting in longer gluing time and reducing production efficiency. Because of the time process, there is a risk of solidification during use, which affects the quality of the product.

[0003] In the prior art, the traditional wind power blade gluing and bonding adopts a fixed point method. The device delivers the mixed adhesive to the paperboard or basin according to the required weight, and the worker manually transports the glue to the designated location. This transportation process consumes a lot of manpower, and the mixed adhesive will solidify and produce a large amount of solid waste, which will have adverse effects on the environment. Therefore, the material loss is also great. Many times, the gluing process on some parts of the wind power blade has not been completed, and the places where the glue has been applied have already solidified, resulting in a decrease in production efficiency and extremely unstable product quality. At the same time, due to the separation of the glue machine and the glue head on both sides, the incoordination between the glue machine and the glue head during the gluing process leads to poor gluing efficiency.

[0004] For example, CN 114289269 B discloses a wind power blade gluing device and method that can automatically position, which includes a positioning guide rail, a self-walking platform, and a gluing tool set on the self-walking platform and moving synchronously with the self-walking platform. The positioning guide rail is set on both sides of the front and rear edges of the blade main mold, and its installation position is determined based on the parting line of the front and rear edges of the blade main mold and the positioning data of the web in the blade, so that the shape of each side of the positioning guide rail is the same as the corresponding side of the blade. By integrating the gluing tool, the self-walking platform, and the positioning guide rail with a specific shape into a wind power blade gluing device that can automatically position, accurate positioning and gluing can be achieved, the problem of uneven and large positional deviation of manual gluing can be solved, bonding defects caused by positional deviation can be eliminated, and product quality can be improved. At the same time, the device can realize synchronous automatic gluing of the adhesive in the web bonding area of the front and rear edges, and improve the work efficiency. However, in actual operation, due to the large size of the wind power blade and the large amount of glue, the gluing process is complicated, and after some parts of the wind power blade have solidified, some parts have not completed the gluing process. In addition, the cost of this structure is high, and it is not suitable for various types of molds.

[0005] For example, a wind power blade gluing process gluing position automatic positioning device and method disclosed in Chinese patent CN 115646764 A belongs to the technical field of wind power blade gluing. The device comprises a wall-mounted track, a crossbeam, a gluing device and a follow-up trolley. The wall-mounted track is installed on the column I-beam of the factory production workshop and is divided into an upper track and a lower track. The upper track and the lower track are respectively provided with an upper pipe and a lower pipe. The upper pipe and the lower pipe jointly support the walking part of the crossbeam. The crossbeam comprises a crossbeam main body and a crossbeam walking part, and the crossbeam walking part is connected with the crossbeam main body through a rotating shaft. The crossbeam provides support and guidance for the gluing device. The gluing device comprises a walking servo hoist, a balancer and a rubber shoe, and is suspended on the crossbeam main body. The follow-up trolley is used for carrying the gluing system and the control system hardware. The present application can meet the gluing process requirements of different gluing areas of the blade, improve the gluing operation efficiency and quality, the cost of the gluing device structure of the structure is high, it is not suitable for various types of molds, and the gluing speed is also slow, resulting in complicated glue supplementing process. After part of the glue injection position on the wind power blade has been solidified, part of the glue injection is not completed, and the work efficiency is poor. SUMMARY

[0006] The purpose of the application is to solve the problems of the prior art. The present application provides a large mold forming wind power blade mobile type rapid gluing method, which can realize rapid glue injection for large size wind power blades, accurate glue injection process and greatly improved operation quality and efficiency.

[0007] Technical scheme: In order to achieve the above purpose, the large mold forming wind power blade mobile type rapid gluing method comprises the following steps:

[0008] Step 1, installation

[0009] Place multiple large tonnage glue machines walking channels in the middle of two super large size wind power blade molds, install a spiral elevator at the end of the large tonnage glue machine walking channel, then install an avoiding device in the middle of the adjacent two large tonnage glue machine walking channels, and determine the number of large tonnage glue machines to be placed on the large tonnage glue machine walking channel according to the glue injection amount of the wind power blade;

[0010] Step 2, pre-checking large tonnage glue machine

[0011] The heavy load navigation vehicle carrying the large tonnage glue machine is transported to the navigation vehicle carrying platform, and then the central control console switch power supply is started. After the weight sensor on the navigation vehicle carrying platform receives the signal, the data is fed back to the PLC circuit. The PLC circuit determines whether the glue amount in the large tonnage glue machine meets the limited value according to the weight sensor feedback data. If the weight sensor data meets the limited value, the PLC circuit sends an opening signal to the central control console. If the weight sensor data does not meet the limited value, the PLC circuit sends a warning signal to the central control console.

[0012] Step three, conveying large tonnage glue machine

[0013] When the central control console receives the opening signal sent by the PLC circuit, the operator presses the opening button of the central control console, the PLC circuit sends a signal to the driving motor, the driving motor rotates clockwise to drive the self-locking screw connected thereto to rotate counterclockwise, thereby gradually moving the navigation vehicle carrying platform upward to a limited position, the position sensor on the frame mechanism sends a signal to the PLC circuit, and when the navigation vehicle carrying platform moves upward to the limited position, the PLC circuit sends a stop rotating signal to the driving motor, and the PLC circuit sends a signal to the vehicle driving motor, and the heavy load navigation vehicle equipped with the large tonnage glue machine moves to a limited position on the large tonnage glue machine walking channel

[0014] Step four, glue preparation

[0015] Repeat step three, sequentially convey a plurality of heavy load navigation vehicles equipped with large tonnage glue machines to the limited position on the large tonnage glue machine walking channel, and the PLC circuit sends a signal to the large tonnage glue machine to rotate and adjust the glue outlet position of the large tonnage glue machine to correspond to the position of the oversized wind power blade mold to prepare for glueing;

[0016] Step five, glueing

[0017] The PLC circuit sends a signal to the vehicle driving motor and the large tonnage glue machine, and the heavy load navigation vehicle drives the large tonnage glue machine to move back and forth at a uniform speed on the large tonnage glue machine walking channel, and the large tonnage glue machine uniformly glues the oversized wind power blade mold, and the movement of the adjacent two heavy load navigation vehicles has a repeated position.

[0018] Step six, avoiding the turning arm

[0019] When the turning arm needs to close the oversized wind power blade mold, the PLC circuit sends a signal to the heavy load navigation vehicle to move to the initial limited position, and then the PLC circuit sends a signal to the air pump to stop inputting gas to the left cylinder and the right cylinder, and the piston rod on the left cylinder and the right cylinder resets back to the piston, thereby making the left avoiding plate and the right avoiding plate disconnect under the action of the left cylinder and the right cylinder. The disconnecting distance of the left avoiding plate and the right avoiding plate is the width required for the turning of the turning arm;

[0020] When the turning arm completes the closing of the super-large size wind power blade mold, the PLC circuit sends a signal to the air pump, the piston rod on the left cylinder and the right cylinder is pushed out, so that the left avoiding plate and the right avoiding plate are respectively pushed up to realize that the left avoiding plate and the right avoiding plate are respectively connected with the walking channel of the adjacent two large tonnage rubber machines, so as to facilitate the heavy load navigation vehicle carrying the large tonnage rubber machine to enter the next large tonnage rubber machine walking channel after entering the left avoiding plate and the right avoiding plate from the large tonnage rubber machine walking channel, and finally reach the navigation vehicle bearing platform at the end of the large tonnage rubber machine walking channel in the frontmost position;

[0021] Step seven, the large tonnage rubber machine falls to the ground

[0022] The PLC circuit sends a signal to the driving motor, the driving motor rotates counterclockwise to drive the self-locking screw connected with it to rotate clockwise, so that the navigation vehicle bearing platform gradually moves downward to the limited position, the position sensor on the frame mechanism sends a signal to the PLC circuit, and when the navigation vehicle bearing platform moves downward to the limited position, the PLC circuit sends a stop rotating signal to the driving motor, so that the heavy load navigation vehicle is positioned to the ground, and the action of step seven is repeated until all the heavy load navigation vehicles are positioned to the ground;

[0023] Step eight, repeat

[0024] Steps two to six are repeated to complete the rubber coating work of the next blade, and batch rubber coating production of wind power blades is realized.

[0025] As a further preferred embodiment of the application, in step three, the number of large tonnage rubber machines distributed at the root of the super-large size wind power blade mold accounts for 70% to 75% of the total number of large tonnage rubber machines.

[0026] As a further preferred embodiment of the application, the root of the super-large size wind power blade mold is 30% to 40% of the total length of the super-large size wind power blade mold.

[0027] As a further preferred embodiment of the application, in step four, the repeated position when the adjacent two heavy load navigation vehicles move is 10cm to 15cm

[0028] As a further preferred embodiment of the application, in step four, the glue output of the large tonnage rubber machine is 10L / min to 20L / min.

[0029] As a further preferred embodiment of the present application, two large-size wind power blade molds are arranged on both sides of the large-tonnage rubber machine walking channel, and a avoiding device for avoiding the turning arm is arranged at the middle of the two large-tonnage rubber machine walking channels on the same straight line. Since the large-size wind power blade mold needs to be closed and opened by the turning arm during the preparation of the wind power blade, the width required for the turning of the turning mechanism is reserved on the large-tonnage rubber machine walking channel, so that the large-size wind power blade mold can be closed and opened without considering the influence of the rubbering process, the avoiding device is opened in real time, the turning mechanism is quickly turned, and the production efficiency is improved.

[0030] The spiral elevator is installed on the large-tonnage rubber machine walking channel at the end of the large-size wind power blade mold, the heavy-load navigation vehicle carrying the large-tonnage rubber machine is lifted and sent into the large-tonnage rubber machine walking channel by the spiral elevator, and when multiple large-tonnage rubber machines are needed, multiple large-tonnage rubber machines are sent into the limited position on the large-tonnage rubber machine walking channel by the spiral elevator in sequence.

[0031] As a further preferred embodiment of the present application, the spiral elevator comprises a navigation vehicle carrying platform, a self-locking screw, a frame mechanism, a driving motor, a speed reducer, a linear guide column and a bottom plate.

[0032] The two oppositely arranged frame mechanisms are vertically installed on the bottom plate, the self-locking screw is fastened on the frame mechanism, the linear guide columns arranged on both sides of the self-locking screw and parallel to the self-locking screw are fastened with the frame mechanism, the two sides of the navigation vehicle carrying platform horizontally installed above the bottom plate are clamped on the two opposite frame mechanisms, and the output end of the speed reducer fixed on the bottom plate is connected with the self-locking screw. The internal thread on the navigation vehicle carrying platform is connected with the external thread on the self-locking screw, and the oppositely arranged linear guide columns are clamped on the side surface of the navigation vehicle carrying platform. The navigation vehicle carrying platform moves up and down in the two frame mechanisms under the rotation of the self-locking screw.

[0033] Since the two linear guide columns and the self-locking screw are located in the same plane of the frame mechanism, and the two frame mechanisms are oppositely arranged, when the two driving motors rotate simultaneously after receiving the PLC circuit signal, the rotation of the driving motor drives the rotation of the two self-locking screws, and the linear guide columns on both sides of the navigation vehicle carrying platform are clamped on the frame mechanism. At this time, the internal thread on both sides of the navigation vehicle carrying platform connected with the self-locking screw is driven to move by the rotation of the two self-locking screws, so that the horizontal height of the navigation vehicle carrying platform is moved.

[0034] As a further preferred embodiment of the present application, the two oppositely arranged self-locking screws are fastened on the frame mechanism, and at least one linear guide column is arranged on both sides of the self-locking screw.

[0035] As a further preferred embodiment of the present application, the heavy-load navigation vehicle comprises a vehicle driving motor, a follower wheel, a limiting wheel and a driving wheel mounted below the vehicle body, the vehicle driving motor is connected with the driving wheel, the limiting wheel fastened below the vehicle body is clamped in the groove on the side of the walking channel of the large-tonnage rubber machine, thereby limiting the position of the heavy-load navigation vehicle relative to the walking channel of the large-tonnage rubber machine in horizontal and width directions.

[0036] The side of the walking channel of the large-tonnage rubber machine is an I-beam, the follower wheel, the limiting wheel and the driving wheel are arranged in pairs, and the limiting wheel is clamped in the groove of the I-beam, thereby ensuring the stability of the heavy-load navigation vehicle in horizontal and vertical directions. The heavy-load navigation vehicle is a trackless flat car purchased from Dongteng Intelligence, and the operation mode and working principle of the heavy-load navigation vehicle are prior art and have been widely used in the prior art. Therefore, the specific structure of the heavy-load navigation vehicle is not repeated here.

[0037] As a further preferred embodiment of the present application, the avoiding device is hinged at the middle of the adjacent two walking channels of the large-tonnage rubber machine, and the avoiding device comprises left and right avoiding plates hinged with the walking channels of the large-tonnage rubber machine through avoiding hinges, and left and right cylinders for controlling the connection and disconnection of the left and right avoiding plates, wherein the left and right cylinders are connected with a gas pump.

[0038] As a further preferred embodiment of the present application, one end of the left and right cylinders is hinged on a support seat for supporting the walking channel of the large-tonnage rubber machine, and the other end of the left and right cylinders is hinged with the left and right avoiding plates, respectively.

[0039] When the gas pump inputs gas to the left and right cylinders, the piston rods on the left and right cylinders are pushed out, so that the left and right avoiding plates are respectively pushed upward to be connected with the adjacent two walking channels of the large-tonnage rubber machine, thereby facilitating the heavy-load navigation vehicle carrying the large-tonnage rubber machine to enter the next walking channel of the large-tonnage rubber machine after entering the left and right avoiding plates from the walking channel of the large-tonnage rubber machine.

[0040] When the gas pump stops inputting gas to the left and right cylinders, the piston rods on the left and right cylinders reset, so that the left and right avoiding plates are disconnected under the action of the left and right cylinders, and the disconnection distance of the left and right avoiding plates is the width required for the turning arm to turn over.

[0041] As a further preferred embodiment of the present application, the sum of the lengths of the left and right avoiding plates is equal to the distance between the adjacent two walking channels of the large-tonnage rubber machine.

[0042] When it is needed to close and open the mold of the super-large size wind power blade mold through the turnover arm, the width required by the turnover mechanism during turnover is reserved on the walking channel of the large tonnage glue machine, so that the super-large size wind power blade mold can be turned over without considering the influence of the glue hitting process, the avoidance device is opened in real time, and the rapid turnover of the turnover mechanism can be realized.

[0043] The large tonnage glue machine installed on the heavy load navigation vehicle moves back and forth on the walking channel of the large tonnage glue machine under the driving of the heavy load navigation vehicle. The glue outlet of the large tonnage glue machine uniformly coats glue on the super-large size wind power blade mold. The coating density of the glue is set according to the requirements of different wind power blades. The large tonnage glue machine in the technical solution is purchased from the supplier DOPAG, and the model is gelcomlx. Since the operation mode and working principle of the large tonnage glue machine are prior art, and the large tonnage glue machine has been widely used in prior art, the specific structure of the large tonnage glue machine will not be repeated here.

[0044] As a further preferred embodiment of the application, the driving motor, the vehicle driving motor and the air pump are respectively connected to the PLC circuit.
