Embodiment 1

[0061] Example 1 as figure 1 As shown, the whole cross-flow fan blade is composed of a single shaft cover 1, multiple middle sections 2 and a single end cover 3 connected in series through ultrasonic welding process, wherein the shaft cover 1 is at the bottom end, and the multiple middle sections 2 (from bottom to top, first to last) in the middle, end cap 3 at the top. Unless otherwise specified, the present invention refers to the shaft cover, the middle joint and the end cover as workpieces when describing.

[0062] Such as figure 2 and image 3 The shown middle section 2 is composed of an A circular disc 4 and a plurality of A blades 5, the cross section of the A blades 5 is arc-shaped, and the rear end of the A blade 5 is connected to the lower surface of the circular disc 4, The upper surface of the A circular disc 4 is provided with the same number of A positioning vanes 6 as the A blades 5, which are used to insert another middle section 2 or an internal repair end...

Embodiment 2

[0095] Example 2 Figure 10 A preferred embodiment suitable for inside repair end caps is shown. and Figure 8 Compared, the difference is that the external repair end cover vibrating plate feeding mechanism 28 is replaced by the inner repair end cover belt line feeding mechanism, and the belt line feeding mechanism of the inner repair end cover includes a storage belt line 33 and a storage belt line 33 The feeding belt line 34 that connects, other embodiment is with embodiment 1.

Abstract

The invention discloses a cross-flow fan blade welding robot, which includes a material distribution module, a material grabbing manipulator, a pre-positioning module, a material feeding module, an ultrasonic welding machine and a material receiving module; the welding robot sends workpieces to the material grabbing manipulator through the material distribution module Preliminary shaping and self-centering by three-jaw clamping, and then sent to the pre-positioning module to realize eight-jaw clamping self-centering and positioning mark rotation alignment, and then through the feeding module to realize four-jaw clamping self-centering, Compensation of translation errors and rotational angle errors as well as blade interpolation for soft landing and rotational search, in turn clamping self-centering and clamping force control with four guide rods in ultrasonic welding machines, two-stage welding head movement and digital power supply The driven ultrasonic transducer completes the welding, and then the receiving module takes out the finished product after welding and sends it to the storage belt line. The invention has the advantages of fast welding cycle, low noise, high yield rate, short line change time, online real-time quality monitoring, stable and reliable operation, and the like.

Description

technical field [0001] The invention relates to the application field of injection molding ultrasonic welding, in particular to a cross-flow fan blade welding robot. Background technique [0002] The cross-flow fan blade has the characteristics of compact structure, small size, large air flow, uniform horizontal direction, long distance and low noise. It is widely used in low-pressure ventilation occasions such as air conditioners, household appliances, tower fans, and air curtains. The cross-flow fan blade is made of engineering plastics, and the components include a single shaft cover, multiple middle sections, a single outer end cover or an inner end cover. In the current mature manufacturing process, ultrasonic welding is the key process for the manufacture of cross-flow fan blades. It is connected in series by means of ultrasonic welding. Taking the cascade link between the middle sections as an example, before welding, dozens of slender and thin blades at the front e...
