Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioner cross-flow fan blade production technology, and in particular to an ultrasonic welding machine for cross-flow fan blades. Background Technology
[0002] Cross-flow fan blades are core plastic components in the air supply systems of the home appliance industry. The finished product is assembled by cascading ultrasonic welding between the shaft cover and the middle section, between middle sections, and between the middle section and the outer or inner end cover. The ultrasonic welding machine for cross-flow fan blades is a high-efficiency welding device specifically designed for the production of cross-flow fan blades in air conditioners, elevators, etc., featuring high precision and good stability.
[0003] Chinese Patent CN207682965U discloses an ultrasonic welding machine for cross-flow fan blades, including a frame with a welding platform and an ultrasonic welding head. Clamping components are located on both sides of the welding platform on the frame, capable of moving in opposite directions to clamp or release the cross-flow fan blades. Each clamping component includes two clamping rods spaced apart, the distance between the two clamping rods being less than the diameter of the cross-flow fan blade. This invention uses four clamping rods on both sides of the welding platform, which can move synchronously and in opposite directions toward the cross-flow fan blade to clamp the unwelded cross-flow fan blade workpiece in the circumferential direction, achieving automatic centering of the workpiece. Therefore, when changing cross-flow fan blade workpieces of different diameters, there is no need to adjust the welding head or the position of the automatic workpiece placement robot arm, thereby improving production efficiency. Furthermore, the ultrasonic welding head is motor-driven, enabling real-time control of the welding position, speed, and pressure, thus improving welding quality.
[0004] Existing cross-flow fan blade ultrasonic welding machines use ultrasonic welding heads to weld and process workpieces. However, the ultrasonic welding head is not easy to dissipate heat in time when it is working continuously, which leads to damage to the ultrasonic welding head and increases the cost of using the ultrasonic welding machine. The connection between the bottom end of the workpiece limiting clamping rod and the base plate of the machine body is not convenient for moving and guiding, which leads to the lowering of the clamping rod adjustment and affects the workpiece limiting clamping operation.

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0030] Example 1
[0031] like Figure 1 - Figure 4 As shown, the present invention proposes an ultrasonic welding machine for cross-flow fan blades, comprising: a base plate 1, a housing 2, a moving assembly, a motor mounting base 5, a heat sink 6, a placement assembly 7, and a clamping assembly 8; the base plate 1 is provided with a guide groove 101 and is connected to the housing 2, the housing 2 being connected to a support plate 3; the moving assembly is connected to the support plate 3; the motor mounting base 5 is connected to the moving assembly, and the motor mounting base 5 is connected to an ultrasonic welding head 501, with the heat sink 6 connected to the periphery of the ultrasonic welding head 501; the heat sink 6 is hollow inside and has an air outlet connecting to the outside. The heat sink 6 is connected to the air inlet pipe 601. The outer wall of the air inlet pipe 601 is connected to the bracket 602. Both sides of the outer wall of the heat sink 6 are connected to clamping blocks 603. The clamping blocks 603 are respectively connected to the support frame 604. The support frame 604 is connected to the support plate 3 and is detachably connected. The placement component 7 is connected inside the housing 2. The clamping component 8 is connected inside the housing 2. The clamping component 8 includes a clamping rod 801, a moving wheel 802 and an adjusting component. The clamping rod 801 is connected inside the housing 2 through the moving wheel 802 and the adjusting component, and the moving wheel 802 is connected inside the guide groove 101. The heat sink 6 is connected to the outside of the heat sink 6 via support frames 604 and clamps 603, thus supporting and connecting the heat sink 6 to the periphery of the ultrasonic welding head 501. The heat sink 6 drives the air inlet pipe 601. The air inlet end of the air inlet pipe 601 is connected to the pipe body via an installation interface, and the pipe body is connected to the blower. When the blower is started, the impeller begins to rotate. The rotating impeller draws air into the air inlet through centrifugal force, then accelerates and compresses the air, finally delivering the air into the pipe body along the air outlet. The pipe body is connected via an installation interface. This allows airflow to be delivered through the air inlet pipe 601 into the heat dissipation shell 6, and then discharged through the air outlet of the heat dissipation shell 6. The air outlet is connected to the periphery of the ultrasonic welding head 501, which helps to dissipate heat from the ultrasonic welding head 501 in a timely manner, thus improving the service life of the ultrasonic welding machine components and enhancing the performance of the cross-flow fan ultrasonic welding machine. Furthermore, a switch button for the ultrasonic welding machine drive structure is set on the outer wall of the housing 2, so that the initial position of the switch button is that the circuit is disconnected. Different buttons can be used to control the start of different electrical components, allowing the ultrasonic welding machine to be operated and run as needed.
[0032] To further explain, bracket 602 is connected to support plate 3, clamping block 603 and heat sink 6 are detachably connected, and air inlet pipe 601 has an installation interface at the air inlet end, which connects to the pipe body, and the pipe body connects to the air outlet of the blower. Clamping block 603 is detachably connected to heat sink 6 via flange bolts, and the lower end of support frame 604 is detachably connected to support plate 3 via flange bolts. First, the support frame 604 is connected to support plate 3, and heat sink 6 is inserted from below ultrasonic welding head 501 and moved on the outer wall. Then, clamping block 603 is connected to heat sink 6, so that support frame 604 and clamping block 603 support heat sink 6. This allows for the installation of heat sink 6 for auxiliary heat dissipation according to the usage requirements of the ultrasonic welding machine, thus improving the usage of the ultrasonic welding machine.
[0033] Further explanation: The adjusting components include a mounting sleeve 803, an adjusting rod 807, and an electric telescopic column 808. The mounting sleeve 803 is connected to the periphery of the clamping rod 801 and to the adjusting rod 807. The adjusting rod 807 is connected to the drive end of the electric telescopic column 808, which is connected inside the housing 2. Three sets of clamping assemblies 8 are provided, and all three sets are connected inside the housing 2. When the workpiece is placed on the placement plate 701, the electric telescopic column 808 is activated. The drive end of the electric telescopic column 808 moves the adjusting rod 807 toward the workpiece. The adjusting rod 807 drives the mounting sleeve 803, which in turn drives the clamping rod 801. The clamping rod 801 moves to the periphery of the workpiece, facilitating workpiece positioning and allowing multiple workpieces to be placed coaxially and concentrically, thus improving the efficiency of ultrasonic welding of air conditioning cross-flow fan blades. After the workpiece welding is completed, the clamping rod 801 moves in the opposite direction via the electric telescopic column 808, allowing the operator to remove the finished workpiece from the placement plate 701.
[0034] Example 2
[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes an ultrasonic welding machine for cross-flow fan blades. Based on the above embodiments, this embodiment also details the specific components and the cooperation method of the moving component and the placement component 7.
[0036] Further explanation: The moving assembly includes a protective shell 4, a support 401, a guide shell 402, a hydraulic cylinder 403, a guide rail 404, a moving block 405, a moving rod 406, and a mounting bracket 407. The protective shell 4 and the support 401 are both connected to the support plate 3. The support 401 is connected to the guide shell 402, and the guide shell 402 is connected to the hydraulic cylinder 403. The guide rail 404 is set on the inner wall of the guide shell 402. The guide rail 404 is connected to the moving block 405. The moving block 405 is connected to the moving rod 406, and the moving rod 406 is connected to the mounting bracket 407. The driving end of the hydraulic cylinder 403 passes through the guide shell 402 and is connected to the moving rod 406. The mounting bracket 407 is connected to the motor mounting base 5, and the hydraulic cylinder 403 is connected inside the protective shell 4. During the movement of the moving rod 406 and the hydraulic cylinder 403, the moving blocks 405 on both sides move synchronously, and the moving blocks 405 move along the guide rail 404, which facilitates the smooth movement of the motor mounting base 5 and improves the use of the ultrasonic welding head 501 for welding workpieces.
[0037] Further explanation: The placement assembly 7 includes a placement plate 701, a connecting plate a 702, a slider 703, a guide rail 704, a guide sleeve 705, a guide rod 706, and an electric telescopic rod 707. The outer wall of the placement plate 701 is connected to the connecting plate a 702, which connects the slider 703 and the electric telescopic rod 707. The slider 703 is connected to the guide rail 704. The guide sleeve 705 is connected to the placement plate 701 via the connecting plate b, and the guide sleeve 705 is slidably connected to the guide rod 706. The connecting plate a 702 moves through the electric telescopic rod 707. The slider 703 is equipped with balls or rollers, allowing the balls or rollers to slide on the guide rail 704. Simultaneously, the connecting plate b moves synchronously, causing the guide sleeve 705 to slide outside the guide rod 706. Through the slider 703, guide rail 704, guide sleeve 705, and guide rod 706, the movement stability of the placement plate 701 is increased, facilitating the placement of workpieces on the placement plate 701.
[0038] The working principle of this utility model is as follows: When using the cross-flow fan blade ultrasonic welding machine, the operator places the air conditioner cross-flow fan blade workpiece on the placement plate 701. The electric telescopic rod 707 is activated by the switch button. The drive end of the electric telescopic rod 707 moves the placement plate 701 down by one workpiece position, thereby placing the second workpiece on the first workpiece, making the two workpieces coaxial and concentric. Then, the clamping assembly 8 limits and clamps the two workpieces. Then, the hydraulic cylinder 403 is activated by the switch button. The hydraulic cylinder 403 drives the moving rod 406 to move downward on the guide shell 402. The moving rod 406 drives the mounting frame 407, and the mounting frame 407 drives the ultrasonic welding head 501 to move downward. The head moves down to the cross-flow fan blade workpiece, and welding begins. After welding is completed, the above steps are repeated until a complete cross-flow fan blade is welded.
[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
