Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner fan blade processing equipment, and in particular to an automatic puncture device for cross-flow middle section blades. Background Technology

[0002] Cross-flow fan blades are a common type of air conditioning fan blade. For example... Figure 1 As shown, the cross-flow fan blade is welded together from a shaft cover 101, a motor end cover 102, and multiple sections of intermediate impeller 103 located between the shaft cover 101 and the motor end cover 102. The blades of the intermediate impeller 103 are unevenly distributed along the circumference. This fan blade structure increases the contact area between the motor end cover and the impeller disc of the intermediate impeller 103 by optimizing the contact surface design, thereby improving the bonding strength.

[0003] In the manufacturing process of cross-flow fan blades, the multi-section intermediate impeller 103 is usually injection molded using the same mold. Since the motor shaft disk adopts an internally fixed assembly method, it is necessary to remove one blade from one of the intermediate sections of the fan blade near the motor shaft disk to make room for screw assembly and fixation.

[0004] The traditional method involves manually breaking off a blade from the middle section to create the screw opening. However, this method has several drawbacks: First, it cannot achieve fully automated welding production, resulting in low production efficiency; second, it requires a large amount of manual labor, increasing production costs; third, it is easy to break off the wrong blade, making the operation difficult and affecting the consistency of product quality; and finally, manual operation may pose safety hazards, increasing the risk of worker injury.

[0005] In addition, the method of manually breaking the blades has the following problems: the position and force of the break are difficult to control precisely, which may result in uneven breaks or damage to adjacent blades; the repeatability and consistency of manual operation are poor, making it difficult to guarantee the quality standards of each product; in large-scale production, the fatigue of manual operation will increase over time, which may lead to a decline in operation quality.

[0029] like Figure 3 and 4As shown, the present embodiment proposes an automatic punching device for the blades of a middle section of a tubular wind turbine, which includes a positioning core 1 for erecting and positioning the middle section wind turbine 103, a driving motor 2 for driving the rotation of the positioning core 1 and the middle section wind turbine 103 thereon, a pressing assembly 3 for axially pressing the middle section wind turbine 103, a punching assembly 4 for punching the blades of the middle section wind turbine 103, and a sensor for detecting the positioning points on the middle section wind turbine 103; the punching assembly 4 is arranged on a rack 10 beside the positioning core 1, and the punching assembly 4 and the driving motor 2 are started and stopped based on the sensor signal; when the sensor detects the positioning points on the middle section wind turbine 103, the driving motor 2 stops, and the output end of the punching assembly 4 is used to punch the blades of the middle section wind turbine 103. Among them, the positioning core 1 is used to erect and position the middle section wind turbine 103, ensuring the stability of the wind turbine during the punching process; the driving motor 2 drives the rotation of the positioning core 1 and the middle section wind turbine 103 thereon, and the sensor detects the positioning points on the middle section wind turbine 103, so that the device can automatically find the blades on the middle section wind turbine 103 for accurate punching; the pressing assembly 3 axially presses the middle section wind turbine 103 to prevent it from moving during the punching process; the punching assembly 4 is used to actually perform the punching operation of the blades. Through the cooperation of the above components, the automatic punching of the blades of the middle section of the tubular wind turbine is realized, and the problems of low efficiency and easy error of traditional manual operation are solved. The technical scheme of the present application realizes the punching of the blades of the middle section of the tubular wind turbine in an automatic manner, significantly improves the production efficiency, and reduces the error rate of manual operation. Compared with the prior art, the technical scheme of the present application has higher accuracy and stability, and can effectively solve the problems of low efficiency and easy error in traditional manual operation.

[0030] In specific embodiments, the output direction of the punching assembly 4 is arranged along the radial direction of the positioning core 1, and the punching assembly 4 includes a punching cylinder 41 and a top block 42 arranged on the output end of the punching cylinder 41. Specifically, the punching cylinder 41 serves as a power source, and directly applies force through the top block 42 on its output end to ensure that the blades can be quickly and accurately punched. Among them, the design of the top block 42 can include various shapes and materials to adapt to blades of different sizes and materials. For example, the top block 42 can be made of hard alloy material to improve its wear resistance and service life. In addition, the shape of the top block 42 can be circular, square or other geometric shapes to better adapt to the shape of the blades and the punching requirements. Therefore, this design not only simplifies the mechanical structure, but also improves the reliability of the operation. By arranging the output direction of the punching assembly 4 along the radial direction of the positioning core 1, the punching action can directly act on the blades of the middle section wind turbine 103, improving the accuracy and efficiency of the punching. Compared with the prior art, this technical scheme avoids the traditional method of manually breaking the blades, reduces the amount of manual labor, improves production efficiency, and reduces the difficulty of operation and the error rate.

[0031] Further, a receiving box 5 is arranged on the frame 10 between the positioning core 1 and the breaking assembly 4; the broken blades in the middle section wind wheel 103 are received by the receiving box 5. The receiving box 5 is arranged to effectively collect the broken blades, avoiding the situation of blade scattering or the need for manual cleaning. The receiving box 5 can be designed to be detachable, facilitating cleaning and maintenance. In addition, the material of the receiving box 5 can be selected to be wear-resistant and corrosion-resistant to prolong the service life. The shape and size of the receiving box 5 can be adjusted according to actual needs to ensure that the broken blades can be completely received. The application solves the problem that the broken blades in the middle section wind wheel 103 cannot be effectively collected by arranging the receiving box 5 on the frame 10 between the positioning core 1 and the breaking assembly 4. The arrangement of the receiving box 5 enables the broken blades to be directly received, avoiding the situation of blade scattering or the need for manual cleaning, thereby improving production efficiency and automation. Compared with the prior art, the technical scheme of the application has higher practicability and reliability, can significantly improve the blade collection efficiency in the production process, reduce manual intervention, and reduce production cost.

[0032] As shown in Figure 4 The outer side edge of the positioning core 1 is radially concave to form an avoiding groove 11; when the middle section wind wheel 103 is sleeved on the positioning core 1, the blades corresponding to the positioning points are aligned with the avoiding groove 11. The technical scheme enables the middle section wind wheel 103 to align the blades corresponding to the positioning points through the avoiding groove 11 when the middle section wind wheel 103 is sleeved on the positioning core 1. This alignment mechanism ensures that when the middle section wind wheel 103 is sleeved on the positioning core 1, the radially inner side of the blades of the middle section wind wheel 103 is supported or limited by the positioning core 1, and only the blades corresponding to the positioning points, i.e. the inner side of the blades that need to be broken, are not supported or limited due to the arrangement of the avoiding groove 11, so that the blades are more easily broken when the breaking assembly 4 exerts force on the blades. In addition, the presence of the avoiding groove 11 also improves the positioning accuracy and simplifies the operation process, making the entire breaking process more efficient and reliable. In the above scheme, the specific implementation of the avoiding groove 11 can include but is not limited to the following: the depth and width of the avoiding groove 11 can be adjusted according to the size and shape of the blades to ensure that the blades can be accurately aligned and smoothly enter the avoiding groove 11; the shape of the avoiding groove 11 can be rectangular, trapezoidal or other suitable shapes to adapt to the design needs of different blades. Compared with the prior art, the technical scheme improves the positioning accuracy of the middle section wind wheel 103 on the positioning core 1 through the design of the avoiding groove 11, simplifies the operation process, and improves the production efficiency. The arrangement of the avoiding groove 11 makes the breaking process more efficient and reliable, reduces the need for manual intervention, and reduces the operation difficulty and labor intensity.

[0033] Further, an annular platform 12 is constructed below the lower edge of the positioning core 1. When the middle section wind wheel 103 is sleeved on the positioning core 1, the lower end surface of the middle section wind wheel 103 is erected on the annular platform 12. Specifically, the annular platform 12 can be constructed by machining a protruding annular structure on the lower edge of the positioning core 1. The height and width of the annular platform 12 can be designed according to the size and weight of the middle section wind wheel 103 to ensure that it can provide sufficient supporting force. The material of the annular platform 12 can be selected as the same metal material as the positioning core 1 to enhance the strength and durability of the overall structure. In addition, the surface of the annular platform 12 can be finely processed to ensure that the lower end surface of the middle section wind wheel 103 can be smoothly erected thereon, avoiding installation errors caused by uneven surfaces. As a preferred embodiment, the inner diameter of the annular platform 12 can be slightly larger than the inner diameter of the middle section wind wheel 103, so that the middle section wind wheel 103 can be smoothly sleeved on the positioning core 1. At the same time, the outer diameter of the annular platform 12 can be slightly smaller than the outer diameter of the middle section wind wheel 103 to ensure that the lower end surface of the middle section wind wheel 103 can be completely erected on the annular platform 12, thereby providing stable support. Briefly and in-depth summary of the above technical solution, the annular platform 12 constructed below the positioning core 1 provides a stable support surface for the middle section wind wheel 103. When the middle section wind wheel 103 is sleeved on the positioning core 1, its lower end surface is directly erected on the annular platform 12, which can ensure the vertical position of the middle section wind wheel 103 on the positioning core 1 is accurate and reliable, and at the same time enhances the stability of the entire structure. In this way, the position of the middle section wind wheel 103 remains fixed during the machining process, reducing the machining errors caused by positional deviation and improving the machining precision and efficiency. Compared with the prior art, the advantages of this technical solution are that the installation of the middle section wind wheel 103 on the positioning core 1 is more stable through the setting of the annular platform 12, avoiding machining errors caused by unstable installation. In addition, the construction of the annular platform 12 is simple and easy to implement, without the need for complex machining processes, reducing production costs. In this way, the machining precision and efficiency of the middle section wind wheel 103 are significantly improved, solving the problem of large labor intensity and low production efficiency caused by manual breaking of blades in traditional methods.

[0034] As shown in Figure 3 The sensor is a laser sensor 6, which is located obliquely above the positioning core 1 and faces the positioning core 1. The setting position and direction of the laser sensor 6 ensure that it can accurately detect the positioning point on the middle section wind wheel 103. The positioning point can refer to Figure 2As shown in the figure, a notch 103a is provided on the inner edge of the wind ring of the middle section wind wheel 103, and the laser sensor 6 is located obliquely above the positioning core 1. This position selection enables the sensor to cover the entire rotation range of the middle section wind wheel 103, thereby ensuring that the positioning point can be detected at any position. The orientation of the laser sensor 6 towards the positioning core 1 further ensures the accuracy and stability of the detection. Through this arrangement, the laser sensor 6 can send signals to the driving motor 2 and the trip assembly 4 in time when the positioning point is detected, achieving precise start-stop control and improving the automation level and processing precision of the entire device. Specifically, the installation angle and position of the laser sensor 6 can be adjusted according to actual application requirements to ensure the best detection effect. For example, the laser sensor 6 can be installed at a 45-degree angle obliquely above the positioning core 1, which can maximize the coverage of the rotation range of the middle section wind wheel 103. In addition, the design of the laser sensor 6 facing the positioning core 1 can ensure that the laser beam can directly irradiate the positioning point, thereby improving the accuracy and response speed of the detection. Thus, the technical solution of the present application solves the problem of accurate detection of the positioning point on the middle section wind wheel 103 through the precise arrangement of the laser sensor 6, ensuring that the driving motor 2 and the trip assembly 4 can accurately start and stop based on the sensor signal. Compared with the prior art, the technical solution of the present application has higher automation level and processing precision, reduces the need for manual intervention, and improves production efficiency.

[0035] Further, the application also proposes that the output end of the driving motor 2 is connected to the positioning core 1 through a synchronous belt wheel assembly. The synchronous belt wheel assembly includes a synchronous belt 21 and synchronous belt wheels 22, which are respectively installed on the output shaft of the driving motor 2 and the input shaft of the positioning core 1, and the power transmission is realized through the transmission of the synchronous belt 21. The synchronous belt wheel 22 assembly can use synchronous belts 21 of different materials, such as rubber synchronous belts and polyurethane synchronous belts, to adapt to different working environments and load requirements. The tooth shape of the synchronous belt wheel 22 can be selected as trapezoidal teeth or circular arc teeth to improve the stability and precision of the transmission. Specifically, the design of the synchronous belt wheel assembly considers the synchronization and accuracy of the transmission, ensuring that the middle section wind wheel 103 can rotate at a predetermined speed and direction. The function of the synchronous belt wheel assembly is to provide stable power transmission, reduce power loss, and ensure the synchronization and accuracy of rotation, so that the sensor can accurately detect the positioning point on the middle section wind wheel 103, and then control the start and stop of the punch-off assembly 4, realizing automatic punch-off operation. As a preferred embodiment, the synchronous belt wheel assembly can also be equipped with a tensioning device to adjust the tension of the synchronous belt 21, ensuring the stability and reliability of the transmission. In addition, the synchronous belt wheel assembly can also be provided with a protective cover to prevent dust and foreign matter from entering, prolonging the service life. Thus, the application transmits the power of the driving motor 2 to the positioning core 1 through the synchronous belt wheel assembly, solving the problem of power transmission between the driving motor 2 and the positioning core 1, and realizing the precise rotation control of the middle section wind wheel 103. Compared with the prior art, the technical scheme of the application has the advantages of stable transmission, high precision, simple structure, easy maintenance, etc., which can effectively improve the working efficiency and reliability of the automatic punch-off device.

[0036] As Figure 3As shown, the pressing assembly 3 includes a pressing cylinder 31 fixed on the frame 10 directly above the positioning core 1, and a pressing plate 32 arranged on the output end of the pressing cylinder 31. The pressing cylinder 31 is driven by air pressure and can provide stable pressing force to ensure that the middle section wind wheel 103 does not move or shake during processing. The design of the pressing plate 32 allows the pressing force to be evenly distributed on the surface of the middle section wind wheel 103, thereby avoiding deformation or damage caused by local stress concentration. Specifically, the fixed position of the pressing cylinder 31 is directly above the positioning core 1, which ensures the vertical application of pressing force and avoids uneven pressing caused by angle deviation. The pressing plate 32 can be made of various materials, such as metal or high-strength plastic, to meet different processing needs. In addition, the surface of the pressing plate 32 can be designed with anti-slip texture or elastic material to increase the contact friction with the middle section wind wheel 103, further improving the pressing effect. As a preferred embodiment, the pressing cylinder 31 can be equipped with a pressure sensor for real-time monitoring of the size of the pressing force, and automatic adjustment through the control system to ensure that the pressing force always remains within the optimal range. Further, the pressing plate 32 can be connected to the pressing cylinder 31 through a quick replacement mechanism to facilitate quick adjustment according to different specifications of the middle section wind wheel 103. Thus, the technical solution of the present application realizes stable pressing of the middle section wind wheel 103 through the combination of the pressing cylinder 31 and the pressing plate 32, solving the problem of movement or shaking of the middle section wind wheel 103 during processing. Compared with the prior art, this scheme not only improves the accuracy and safety of processing, but also significantly improves production efficiency and operational convenience through automatic adjustment and quick replacement mechanism.

[0037] In a further aspect, a conveyor belt 71 is further included for conveying the mid-section wind wheel 103, and a mechanical gripper 72 is further included for moving the mid-section wind wheel 103 on the conveyor belt 71 to the positioning core 1. The conveyor belt 71 is a common automated conveying device, usually driven by a motor, and conveys materials from one location to another through a belt or chain. In this application, the conveyor belt 71 is used to convey the mid-section wind wheel 103 from the production line to the designated location. The conveying path of the conveyor belt 71 can be designed according to the actual production needs, such as straight-line conveying, curved conveying, or ring conveying. The conveying speed of the conveyor belt 71 can be adjusted by a motor speed regulator to adapt to different production rhythms. The mechanical gripper 72 is an automated device for grabbing and moving objects, usually driven by a pneumatic cylinder or motor, and achieves grabbing of objects through devices such as clamping jaws or suction cups. In this application, the mechanical gripper 72 is used to grab the mid-section wind wheel 103 from the conveyor belt 71 and accurately place it on the positioning core 1. The grabbing method of the mechanical gripper 72 can be designed according to the shape and size of the mid-section wind wheel 103, such as a clamping jaw gripper or a suction cup gripper. The movement path of the mechanical gripper 72 can be controlled through a mechanical arm or guide rail to achieve accurate positioning and placement. Specifically, the combination of the conveyor belt 71 and the mechanical gripper 72 realizes the automated conveying and positioning of the mid-section wind wheel 103. The conveyor belt 71 is responsible for conveying the mid-section wind wheel 103 from the production line to the designated location, and the mechanical gripper 72 is responsible for grabbing the mid-section wind wheel 103 from the conveyor belt 71 and accurately placing it on the positioning core 1. The combination of these two technical features solves the problems of high labor intensity, low efficiency, and easy errors in traditional manual operation, and realizes fully automated production. Thus, by introducing the conveyor belt 71 and the mechanical gripper 72, the application realizes the automated conveying and positioning of the mid-section wind wheel 103. The combination of the conveyor belt 71 and the mechanical gripper 72 not only improves production efficiency, but also reduces the error rate of manual operation, realizing fully automated production. Compared with the prior art, the technical scheme of the application has obvious advantages and can effectively solve the problems existing in traditional manual operation.

[0038] As a preferred embodiment, a photoelectric sensor 73 is arranged on the rack 10 beside the conveying path of the conveyor belt 71, and the start and stop of the mechanical gripper 72 and the conveyor belt 71 are controlled based on the sensing signal of the photoelectric sensor 73. The photoelectric sensor 73 is used to detect the position of the mid-section wind wheel 103, and when the photoelectric sensor 73 detects that the mid-section wind wheel 103 reaches the designated location, the conveyor belt 71 stops running, and the mechanical gripper 72 starts working to grab and place the mid-section wind wheel 103 on the positioning core 1. This control method further improves the degree of automation, reduces manual intervention, and improves production efficiency.

[0039] Specifically, the photoelectric sensor 73 can be installed at the entrance, exit or middle position of the conveying belt 71 for detecting whether the middle section wind wheel 103 reaches the designated position. When the photoelectric sensor 73 senses the middle section wind wheel 103, a signal will be sent to the control system, and the control system will control the action of the mechanical gripper 72 and the start-stop of the conveying belt 71 according to the signal. For example, when the photoelectric sensor 73 senses that the middle section wind wheel 103 reaches the end of the conveying belt 71, the control system will start the mechanical gripper 72 to grab the middle section wind wheel 103 from the conveying belt 71 and move it to the positioning core 1. As a preferred embodiment, the control of the conveying belt 71 and the mechanical gripper 72 can be automated by using a PLC (Programmable Logic Controller) to improve the stability and response speed of the system. In addition, the signal processing of the photoelectric sensor 73 can use digital filtering technology to reduce false triggering and improve detection accuracy. By introducing the conveying belt 71 and the mechanical gripper 72, the application realizes the automatic conveying and positioning of the middle section wind wheel 103. The conveying belt 71 is responsible for conveying the middle section wind wheel 103 from the production line to the designated position, while the mechanical gripper 72 is responsible for grabbing the middle section wind wheel 103 from the conveying belt 71 and accurately placing it on the positioning core 1. The setting of the photoelectric sensor 73 enables the start-stop of the mechanical gripper 72 and the conveying belt 71 to be controlled based on the sensing signal, thereby ensuring that the conveying and positioning process of the middle section wind wheel 103 is more accurate and efficient. This technical solution solves the problems of large labor, low production efficiency and high operation difficulty in traditional manual operation through automation, significantly improving production efficiency and product quality.
