Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an apparatus for double-sided dispensing and curing of adhesive on a fan, a six-station dispensing and balancing machine, and a dispensing and curing method. Background Technology

[0002] In the fan manufacturing process, dynamic balancing is often required to improve operational stability and reduce vibration and noise. Among these methods, adhesive dispensing compensation is widely used due to its flexibility and good material compatibility. This involves applying a suitable amount of adhesive to a specific phase position of the fan based on its measured imbalance, which, after curing, forms a mass compensation block to offset the original imbalance. For double-sided fans, dispensing and curing operations are often performed separately on the front and back sides.

[0003] Existing equipment is typically designed for single-sided dispensing and cannot handle double-sided dispensing. Although some equipment is designed with a flipping mechanism to achieve double-sided dispensing, the following problems are common: First, dispensing and curing use a single turntable or straight flow channel, which cannot achieve parallel processing of the first and second sides, resulting in low production efficiency; second, manual or semi-automatic flipping leads to positioning errors, affecting the accuracy of dispensing position and thus reducing the yield rate. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low production efficiency and low yield rate of traditional double-sided dispensing equipment for fans.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] According to a first aspect of the present invention, an apparatus for double-sided adhesive dispensing and curing of a fan is provided, comprising: a first rotating mechanism for carrying a fan to be processed and driving the fan sequentially through a first vision station, a first dispensing station, and a first ultraviolet curing station to perform adhesive dispensing and curing on a first side of the fan; a second rotating mechanism for carrying the fan to be processed and driving the fan sequentially through a second vision station, a second dispensing station, and a second ultraviolet curing station to perform adhesive dispensing and curing on a second side of the fan; a conveying mechanism disposed between the first rotating mechanism and the second rotating mechanism for picking up the fan with the first side adhesive dispensing and curing completed from the first rotating mechanism and conveying it to the second rotating mechanism; and a first flipping mechanism disposed on one side of the second vision station for flipping the fan conveyed to the second rotating mechanism by 180°.

[0007] Optionally, the first rotating mechanism includes a first turntable with a plurality of fixtures for fixing the fan arranged circumferentially on the first turntable. The first turntable is rotatably configured to move the fan between the first vision station, the first dispensing station, the first ultraviolet curing station, and the waiting station.

[0008] Optionally, a second flipping mechanism is provided on one side of the first vision station for selectively flipping the fan on the first vision station by 180°; a third flipping mechanism is provided on the waiting station side of the second rotation mechanism for flipping the fan on the waiting station by 180°.

[0009] Optionally, the second rotating mechanism includes a second turntable with a plurality of fixtures for fixing the fan arranged circumferentially on the second turntable. The first turntable is rotatably configured to move the fan between the second vision station, the second dispensing station, the second UV curing station, and the waiting area.

[0010] Optionally, both the first and second ultraviolet curing stations are equipped with ultraviolet curing light sources; both the first and second vision stations are equipped with vision cameras.

[0011] Optionally, the first rotating mechanism and the second rotating mechanism are both independent turntable structures, and the two are arranged horizontally side by side; the conveying mechanism is located between the two turntable structures and is used to transfer the fan between the two.

[0012] Optionally, both the first dispensing station and the second dispensing station are equipped with high-precision dispensing valves.

[0013] Optionally, a control unit is also included. The control unit is signal-connected to the first vision station, the first dispensing station, the second vision station, and the second dispensing station. It is used to perform dispensing at the first dispensing station based on the imbalance information of the first surface of the fan and the position information provided by the first vision station, and to perform dispensing at the second dispensing station based on the imbalance information of the second surface of the fan and the position information provided by the second vision station.

[0014] According to a second aspect of the present invention, a six-station dispensing balancing machine is provided, comprising a feeding station, an initial imbalance measurement station, a re-imbalance measurement station, an unloading station, and the aforementioned apparatus for double-sided dispensing and curing of a fan.

[0015] According to a third aspect of the present invention, a method for double-sided adhesive dispensing and curing of a fan is provided, applied to the aforementioned apparatus, comprising: transporting a fan for which an initial imbalance measurement has been completed to a first vision station of a first rotating mechanism; using the first rotating mechanism to move the fan to the first dispensing station, and dispensing adhesive at a relative position on the first side of the fan based on imbalance information of the first side of the fan and position information provided by the first vision station; using the first rotating mechanism to move the fan to a first ultraviolet curing station to cure the adhesive on the first side of the fan; transferring the fan with the first side cured to a waiting station via the first rotating mechanism; using the transport mechanism to move the fan at the waiting station to a second vision station of a second rotating mechanism, and rotating the fan 180° using the first flipping mechanism; using the second rotating mechanism to move the fan to the second dispensing station, and dispensing adhesive at a relative position on the second side of the fan based on imbalance information of the second side of the fan and position information provided by the second vision station; and using the second rotating mechanism to move the fan to the second curing station to cure the adhesive on the second side.

[0016] The advantages of this invention are: by forming a dual-flow production line through the first rotating mechanism and the second rotating mechanism, and in conjunction with the automatic flipping mechanism, a continuous production line is formed, eliminating the manual loading and unloading, flipping and repetitive positioning links, significantly improving production efficiency and realizing fully automatic continuous production.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 2 As shown, a double-sided adhesive dispensing and curing device for a fan includes a first rotating mechanism, a second rotating mechanism, a conveying mechanism 7, a first flipping mechanism 8, a first dispensing station 2, a second dispensing station 5, a first ultraviolet curing station 3, a second ultraviolet curing station 6, and a control unit. This device is used to sequentially dispense adhesive and perform ultraviolet curing on the two opposing surfaces of a fan, achieving high-precision dynamic balance correction.

[0024] The first rotating mechanism adopts a horizontally arranged turntable structure. Multiple fixtures are evenly arranged circumferentially on the turntable, each fixture used to fix a fan to be processed. The turntable can rotate around its central axis, causing the fan it carries to sequentially pass through the first vision station 1, the first dispensing station 2, the first UV curing station 3, and the waiting station. At the first vision station 1, the vision camera reads the identification mark on the fan to determine the position parameters of the first surface imbalance. Simultaneously, a second flipping mechanism 9 is provided on one side of this station, which can selectively flip the fan 180° to determine whether to process surface A or surface B first. Then, it rotates with the turntable into the first dispensing station 2, where it receives the dispensing operation planned based on the fan's first surface imbalance information and visual position parameters. Next, it enters the first UV curing station 3, where the dispensed area is irradiated by a UV curing light source located at this station, causing the adhesive to cure rapidly. Finally, it reaches the waiting station, waiting to be picked up by the transport mechanism 7.

[0025] The second rotating mechanism uses a second turntable with the same structure as the first rotating mechanism, arranged horizontally and placed side-by-side on the same working plane. The second turntable also has multiple fixtures along its circumference for fixing the fan. Its rotation causes the fan to sequentially pass through the second vision station 4, the second dispensing station 5, the second UV curing station 6, and the waiting station. The second vision station 4 is located at the output end of the conveying mechanism 7 and is used to receive the conveyed fan. A first flipping mechanism 8 is provided on one side of this station to flip the fan 180° so that the second side faces upwards. The second vision station 4 is equipped with a vision camera to read markings and determine the position parameters of the second side's imbalance. The fan then rotates with the second turntable into the second dispensing station 5, where dispensing is performed based on the imbalance information of its second side and the visual position parameters. It then enters the second UV curing station 6, where the UV curing light source completes the adhesive curing. Finally, at the waiting station, a third flipping mechanism 10 is provided on one side to flip the fan, which has undergone double-sided processing, another 180° to restore it to its initial orientation for subsequent unloading.

[0026] The conveying mechanism 7 is located between the first turntable and the second turntable. It is equipped with a clamping component and can accurately pick up the fan that has completed the first surface curing from the waiting station and transport it to the second vision station 4 of the second rotating mechanism.

[0027] Both the first dispensing station 2 and the second dispensing station 5 are equipped with high-precision dispensing valves. The control unit is signal-connected to the two dispensing stations, receives imbalance data from the first and second sides of the fan from the automatic balance detection system, generates corresponding dispensing paths and glue quantity parameters based on this data, and adjusts the high-precision dispensing valves in real time to execute dispensing.

[0028] Both the first UV curing station 3 and the second UV curing station 6 are equipped with UV curing light sources, which can fully cure the adhesive layer within a few seconds, preventing the adhesive from flowing or shifting, and ensuring the accuracy of the dispensing position and the structural strength.

[0029] In the entire device, the first rotating mechanism and the second rotating mechanism are arranged horizontally side by side as two independent turntable systems, without interfering with each other. The conveying mechanism 7 is centrally located, and its movement trajectory covers the area between the waiting station of the first rotating mechanism and the second vision station 4, ensuring that the fan moves between the two turntables.

[0030] The working process of the device is as follows: The fan is first installed in the fixture of the first turntable, and the first vision positioning, first surface dispensing and UV curing are completed sequentially with the turntable; then it is picked up by the conveying mechanism 7 and transported to the second vision station 4; the first flipping mechanism 8 flips 180°; the second turntable drives the fan to complete the second vision positioning, second surface dispensing and UV curing; finally, the third flipping mechanism 10 restores the initial orientation at the waiting station of the second rotation mechanism to complete the unloading.

[0031] Example 2

[0032] like Figure 1 As shown, a fan double-sided dispensing and curing device includes a first rotating mechanism, a second rotating mechanism, a conveying mechanism 7, a dispensing assembly, an ultraviolet curing light source, and a control unit. This device is used to sequentially perform high-precision dispensing and ultraviolet curing treatment on the two end faces of a fan to achieve dynamic balance correction.

[0033] The entire device is integrated into a six-station dispensing and balancing machine, which also includes a loading station 11, an initial imbalance measurement station 12, a re-imbalance measurement station 13, and an unloading station 14. After the fan enters from the loading station 11, the imbalance is first measured at the initial measurement station 12. Then, it is fed into the device to complete double-sided dispensing and curing. The balancing effect is then verified at the re-imbalance measurement station 13, and qualified products are output from the unloading station 14. Through the independent operation of the first and second rotating mechanisms, the precise docking of the conveying mechanism 7 and multiple flipping mechanisms, the integrated operation of automatic double-sided dispensing, synchronous curing, and dynamic balancing correction of the fan is realized.

[0034] Example 3

[0035] The dispensing and curing method for the double-sided dispensing and curing device for fans in Example 1 is as follows:

[0036] The fan, whose imbalance detection has been completed, is positioned and installed on the first vision station 1 of the first rotating mechanism;

[0037] The fan is moved to the first dispensing station 2 using the first rotating mechanism. Based on the imbalance information of the first surface of the fan and the position information provided by the first vision station 1, dispensing is performed at the relative position of the first surface of the fan.

[0038] The fan is moved to the first ultraviolet curing station 3 by the first rotating mechanism to cure the adhesive on the first surface;

[0039] The fan, after the first surface has been cured, is transferred to the waiting station via the first rotating mechanism;

[0040] The fan waiting at the workstation is moved to the second vision workstation 4 of the second rotating mechanism by the conveying mechanism 7, and the fan is rotated 180° by the first flipping mechanism 8.

[0041] The fan is moved to the second dispensing station 5 using the second rotating mechanism. Based on the imbalance information of the second surface of the fan and the position information provided by the second vision station 4, dispensing is performed at the relative position of the second surface of the fan.

[0042] The fan is moved to the second UV curing station 6 by the second rotating mechanism to cure the adhesive on the second surface.

[0043] In the above process, the first and second rotating mechanisms operate independently, ensuring that the fan can simultaneously perform double-sided dispensing and curing. The conveying mechanism 7 uses a vacuum suction cup in conjunction with a motor drive to achieve non-destructive gripping and precise rotation of the fan. The dispensing station is equipped with a high-precision vision positioning system to read imbalance data in real time and dynamically adjust the dispensing coordinates. The ultraviolet curing station uses ultraviolet light irradiation to quickly cure the adhesive. In a preferred embodiment, the first ultraviolet curing station 3 and the second ultraviolet curing station 6 use ultraviolet light sources with the same parameters to ensure consistent double-sided curing results.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
