Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, and in particular to an integrated machine for assembling, welding and testing fans for new energy vehicles. Background Technology

[0002] The fan assembly for new energy vehicles consists of a spindle and a cover. Its installation requires the cover to be placed on top of the spindle and welded together. After welding, the installation height of the spindle also needs to be checked. If the spindle extends too far out of the cover or is too far to the end, it does not meet the requirements. After the product is qualified, it needs to be placed in a tray for subsequent use. This involves many processes and steps. Currently, most of the assembly is done by manual labor in conjunction with multiple machines in a semi-automatic manner, which is inefficient and the equipment occupies a lot of space.

[0003] Mandrel products are precision parts, and the processing and assembly process must not cause scratches on the mandrel surface. It is necessary to observe no scratches with a 40x magnifying glass, which is very difficult to achieve. At present, most mandrel product carriers are made of mold steel. In actual use, dust particles will be adsorbed on the inner wall of the carrier. When the mandrel is placed, the dust particles will cause scratches on the mandrel surface. In addition, mandrel products are asymmetrical products, and the installation direction needs to be identified. The chamfered end is facing down, and the direction identification is also quite troublesome. It is currently difficult to solve this problem, and most of them are operated manually in a clean environment.

[0004] In addition, there are four mounting holes on the upper part of the cover, one of which is waist-shaped. When the material is round, the position of the waist-shaped hole is difficult to control. However, there are requirements for the placement angle of the waist-shaped hole during product assembly. Therefore, the placement angle needs to be adjusted before assembling with other parts. If the product is placed first by a camera and then a robot is used to grab it and turn it to the assembly angle, this requires a precision robot, which is expensive and the material loading is relatively full, resulting in low overall assembly efficiency.

[0005] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design an integrated machine for assembling, welding and testing new energy vehicle fans. Summary of the Invention

[0006] The main technical problem solved by this invention is to provide an integrated machine for assembling, welding and testing new energy vehicle fans, which solves the problems of mandrel scratches and product placement angles, automatically assembles and tests products, and accelerates the overall assembly and production pace.

[0010] The cover feeding mechanism includes a linear vibrating feeder, a V-shaped stop, a second camera assembly, a steering and alignment assembly, and a conveying module. The outer end of the discharge position of the linear vibrating feeder is equipped with a V-shaped stop for blocking the cover. The upper end of the discharge position is connected to a second camera assembly for taking pictures and identifying the position of the waist-shaped hole of the cover. The lower end of the discharge position is connected to a steering and alignment assembly for rotating the cover to the installation angle.

[0042] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0043] Please see Figures 1 to 11 The embodiments of the present invention include:

[0044] A new energy vehicle fan assembly, welding and testing integrated machine includes a box-type protective cover 1, a turntable mechanism 2 located inside the protective cover 1, a mandrel feeding mechanism 3, a cover feeding mechanism 4 arranged around the turntable mechanism 2, and a mandrel installation height detection mechanism 6. The mandrel installation height detection mechanism 5 is provided with a feeding buffer installation mechanism 7 for placing finished products at its side end.

[0045] The turntable mechanism 2 includes a turntable 21 and four sets of carriers 22 evenly distributed on the turntable 21. The carriers 22 are used to fit the positioning cover 02. The upper end of the carrier 22 is fitted with a ceramic block 23 for positioning and placing the mandrel 01. The ceramic block 23 is provided with mounting holes for placing the mandrel. The ceramic glaze on the surface of the ceramic block 23 is smooth and will not attract dust.

[0046] The mandrel loading mechanism 3 includes a mandrel tray loading device 31, a three-axis pick-and-place module 32 located on the mandrel tray loading device 31, a directional adsorption device 33 for placing the mandrel that is connected to the three-axis pick-and-place module 32, and a first camera assembly 34 located above the directional adsorption device 33. The three-axis pick-and-place module 32 picks up the mandrel that is placed horizontally at the mandrel tray loading device 31 and places it at the directional adsorption device 33. The first camera assembly 34 identifies the end of the mandrel with the bevel, and the directional adsorption device 33 is driven to rotate so that the end of the mandrel with the bevel faces downward.

[0047] The cover feeding mechanism 4 includes a linear vibrating feeder 41, a V-shaped stop 42, a second camera assembly 43, a steering and alignment assembly 44, and a conveying module 45. The outer end of the discharge position of the linear vibrating feeder 41 is equipped with a V-shaped stop 42 for blocking the cover. The upper end of the discharge position is connected to a second camera assembly 43 for taking pictures and identifying the position of the waist-shaped hole of the cover. The lower end of the discharge position is connected to a steering and alignment assembly 44 for rotating the cover to the installation angle. The side end of the linear vibrating feeder 41 is also equipped with a conveying module 45 for picking up and placing the cover.

[0048] The steering and alignment assembly 44 includes a lifting cylinder 441, a lifting frame 442 driven upward by the lifting cylinder 441, a motor 443 mounted on the lifting frame 442, and a lifting and alignment rod driven to rotate by the motor. The top of the lifting and alignment rod 444 includes a horizontal part for supporting the cover and a positioning cone part passing through the center of the cover. The upper end of the cover is provided with four mounting holes, one of which is oblong and the others are circular. Since the cover is vibrated and fed by a linear vibrating feeder 41, the position of the oblong hole is difficult to control. However, there are requirements for the placement angle of the oblong hole during product assembly. Therefore, the placement angle needs to be adjusted before assembling with other parts. When the cover is vibrated and conveyed to the discharge position, the lifting cylinder 441 drives the lifting and alignment rod 444 to lift and support the cover. The motor 443 drives the lifting and alignment rod 444 to rotate until the oblong hole on the cover rotates to the required angle. Then the steering and alignment assembly 444 resets.

[0049] The turntable mechanism 2 also includes a pressing component 24 opposite to the mandrel feeding mechanism 3 and used to press the mandrel into place, and an optical fiber sensor 25 opposite to the cover feeding mechanism 4 and used to detect and identify whether there is a cover. The pressing component 24 and the optical fiber sensor 25 are both mounted on the turntable 21 via brackets. The pressing component 24 includes a horizontally mounted slide cylinder 241 and a pressing cylinder 242 vertically mounted on the slide of the slide cylinder 241 via a connecting plate.

[0050] The mandrel tray feeding device 31 includes a stackable mandrel tray hopper 311, a conveyor line 312 for conveying mandrel trays located below the stackable mandrel tray hopper 311, and a plurality of mounting slots for horizontally placing mandrels arranged in an array on the mandrel tray.

[0051] The laser welding mechanism 5 includes a laser welding machine 51, a lifting cylinder 52, and a welding cover 53. The laser welding machine 51 is aligned with the product on the carrier 22. The lifting cylinder 52 is located below the laser welding machine 51. The lifting slide of the lifting cylinder 52 is equipped with a welding cover 53 that can cover the carrier. During the welding process, it can prevent dust from entering the welding area, ensuring welding quality, and can prevent welding fumes from overflowing and affecting the installation of the previous process.

[0052] The mandrel mounting height detection mechanism 6 includes a material handling robot 61, a turntable cylinder 62, a rotary table 63, a positioning carrier 64, a magnetic block 65, and a displacement sensor 66. The material handling robot 61 is located on the side of the turntable 21. The turntable cylinder 62 is mounted on the side of the material handling robot 61 via a bracket. A rotary table 63 is mounted on the turntable cylinder 62. Two positioning carriers 64 for positioning products are mounted on the rotary table 63. The positioning carriers 64 have mandrel through holes 640. The dual positioning carriers 64 can perform uninterrupted testing, improving detection efficiency. A magnetic block 65 for adsorbing products is embedded in the top of the positioning carrier 64. A displacement sensor 66 for detecting the mandrel orientation and mandrel height is mounted on the side of the turntable cylinder 62. The positioning carrier 64 is hollow, and the displacement sensor 66 points towards the mandrel through hole 640.

[0053] The material feeding buffer installation mechanism 7 includes a dual-station pallet lifting device 71, a fixed frame 72, a Y-axis drive module 73, an X-axis drive module 74, a transfer plate 75, pallet suction cups 76, and a finished product adsorption module 77. The dual-station pallet lifting device 71 is fixed on the inner frame of the protective cover 1. Empty finished product pallets are stacked on one of the pallet lifting devices 71. The fixed frame 72 is mounted on the dual-station pallet lifting device 71. The Y-axis drive module 73 is installed on the fixed frame 72. The X-axis drive module 74 is installed on the sliding block of the Y-axis drive module 73. The other end of the X-axis drive module 74 is slidably connected to the fixed frame 72 through a linear slide rail. The transfer plate 75 is installed at the bottom of the X-axis drive module 74. Several pallet suction cups 76 for adsorbing pallets are installed on the transfer plate 75. The finished product adsorption module 77 is installed on the sliding block of the X-axis drive module 74.

[0054] In operation, the three-axis pick-and-place module 32 picks up the mandrel placed laterally at the mandrel tray loading device 31 and places it at the steering adsorption device 33. The first camera component 34 identifies the mandrel with the beveled end, and the steering adsorption device 33 is driven to rotate, turning the mandrel with the beveled end downwards. The mandrel 01 falls into the ceramic block 23 of the carrier 22. The pressing component 24 extends to press the mandrel 01 into place, and the turntable 21 drives the carrier 22 to... 2. Moving to the next station, when the cover 02 is vibrated and conveyed to the discharge position, the lifting cylinder 441 drives the lifting and straightening rod 444 to lift and support the cover. The motor 443 drives the lifting and straightening rod 444 to rotate until the oblong hole on the cover is rotated to the required angle. The handling module 45 grabs the cover 02 and puts it on the carrier 22. The upper part of the mandrel 01 passes through the cover 02, and then the steering and straightening component 44 is reset. The turntable 21 continues to drive the carrier 22 to the next station, and the lifting cylinder 52 drives the welding cover 53. The laser welding machine 51 moves down to cover the carrier 22, welding the mandrel 01 and the upper part of the cover 02 together. The turntable 21 continues to drive the carrier 22 to the next station. The material handling robot 61 picks up the welded product and places it on the positioning carrier 64. The magnetic block 65 holds the product in place. The displacement sensor 66 detects the presence of the mandrel and its extension length. After passing the detection, the Y-axis drive module 73 drives the X-axis drive module 74 to move in the Y direction, thereby moving the transfer device at the bottom of the X-axis drive module 74. The plate 75 moves, the pallet suction cup 76 picks up the pallet, and the empty pallet is transferred to the pallet lifting device 71 at another station. The Y-axis drive module 73 and the X-axis drive module 74 work together to drive the finished product adsorption module 77 to adsorb the finished product and place it in the mounting slot of the pallet. The dual-station pallet lifting device 71 continuously provides pallets to ensure the production rhythm. The Y-axis drive module 73 and the X-axis drive module 74 can synchronously drive the placement of pallets and the gripping of finished products. It is a multi-purpose machine with a simplified structure and cost savings.
