Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of TR assembly assembly on active phased array radar antenna, and particularly relates to a TR assembly assembly method on active phased array radar antenna. BACKGROUND
[0002] The TR assembly is one of the core components of the active phased array radar antenna, and is numerous. When assembled on the antenna array surface, the radio frequency interface located at the lower end surface is connected with the radio frequency interface on the antenna array surface through the KK connector, and the fixed multi-core connector located at the lower end surface is connected with the floating multi-core connector on the antenna array surface. After assembly, each TR assembly is vertically arranged on each cold plate on the antenna array surface and located between two ribs on the cold plate, and is limited by the ribs.
[0003] Currently, the TR assembly is assembled on the antenna array surface by using a mechanical clamp, a flexible jaw or a vacuum chuck to grab and position the TR assembly.
[0004] The TR assembly is grabbed and positioned by the mechanical clamp, and the TR assembly is clamped from both sides. The structure size is large, and the space between adjacent TR assemblies and their cold plates on the antenna array surface is small, which is prone to interference problems. In addition, there is a lack of corresponding safety protection measures, which can easily cause damage to the TR assembly and its corresponding contact components.
[0005] The TR assembly is grabbed and positioned by the flexible jaw, and the TR assembly is clamped from both sides. The structure size is also large, and in the case that the space between adjacent TR assemblies and their cold plates on the antenna array surface is small, interference problems are prone to occur. In addition, the vertical state of the TR assembly cannot be ensured during assembly, reliable positioning of the TR assembly is difficult to achieve, and there is a lack of corresponding safety protection measures, which can easily cause damage to the TR assembly and its corresponding contact components.
[0006] The TR assembly is grabbed and positioned by the vacuum chuck, and the thickness of the TR assembly is small. The top end surface lacks a large size plane for the vacuum chuck to adsorb, and it is difficult to grab and position the TR assembly. In addition, there is a lack of corresponding safety protection measures, which can easily cause damage to the TR assembly and its corresponding contact components.

In the absence of clear evidence that the above content has been disclosed on the filing date of the present application, the above background art should not be used to evaluate the novelty and inventiveness of the present application.

[0084] The active phased array radar antenna upper TR assembly assembly method is as shown in the following steps: Figure 3
[0085] Step one: control the mechanical arm to move the vision device to position the TR assembly 17.
[0086] Step two: control the mechanical arm to make the positioning protrusions on the horizontal positioning plate 19 rest on the top end face of the TR assembly 17.
[0087] Step three: control the horizontal drive cylinder 12 to make the two horizontal positioning columns on the grabbing handle 16 fit into the two positioning holes on the top side wall of the TR assembly 17.
[0088] Step four: control the vertical drive cylinder 6 to move the TR assembly 17 upward so that the top end face of the TR assembly 17 tightly abuts against the positioning protrusions on the horizontal positioning plate 19 to vertically fix the TR assembly 17.
[0089] Step five: control the mechanical arm with the auxiliary vision device to position the position of the radio frequency interface on the lower end face of the TR assembly 17.

[0092] Step eight, control the mechanical arm to move the vision equipment to position the position of the cold plate 22 and the rib strip 23 on the antenna array surface 20;
[0093] Step nine, control the mechanical arm to make the TR assembly 17 deviate from the cold plate 22 by a certain distance in the horizontal direction, which can be 2mm, and insert downward between the two rib strips 23, so as to avoid direct contact with the cold plate 22 and cause friction damage in the process of downward insertion, as shown in Figure 3
[0094] Step ten, control the mechanical arm to make the TR assembly 17 move in the horizontal direction and abut to the surface of the cold plate 22, in the process, if the three-way pressure sensor detects that the pressure reaches the horizontal pressure limit value, it is considered that the TR assembly 17 has abutted to the surface of the cold plate 22 in place, and then can be bonded or fixed to the surface of the cold plate 22 through bolts and other components, and control the mechanical arm to stop horizontal action to avoid causing the TR assembly 17 to be damaged by greater stress;

[0096] If the three-way pressure sensor detects that the pressure reaches the vertical pressure limit value during the docking process of the radio frequency interface on the lower end face of the TR component 17 and the radio frequency interface on the antenna array surface 20, the fixed multi-core connector on the lower end face of the TR component 17 and the floating multi-core connector on the antenna array surface, the control arm stops the downward insertion action to avoid causing the TR component 17 to be damaged by a larger stress, and controls the mechanical arm to move the TR component 17 upward to keep the radio frequency interface on the lower end face of the TR component 17 and the radio frequency interface on the antenna array surface 20, the fixed multi-core connector on the lower end face of the TR component 17 and the floating multi-core connector on the antenna array surface in weak contact, that is, in an incomplete loosening state, controls the vertical drive cylinder 6 to make the two horizontal positioning columns on the grabbing handle 16 loose in the two positioning holes on the top side wall of the TR component 17 due to the gap fit, releases the vertical fixation of the TR component 17, and enables the TR component 17 to adaptively adjust the angle under the action of the weak contact force, so that the radio frequency interface on the lower end face of the TR component 17 slides to the radio frequency interface on the antenna array surface 20, the fixed multi-core connector on the lower end face of the TR component 17 slides to the floating multi-core connector on the antenna array surface, that is, has the same inclination angle between each other, controls the mechanical arm to push the TR component 17 downward to make the radio frequency interface on the lower end face of the TR component 17 and the radio frequency interface on the antenna array surface 20, the fixed multi-core connector on the lower end face of the TR component 17 and the floating multi-core connector on the antenna array surface docked in place.
[0097] If the three-way pressure sensor detects that the pressure reaches the vertical pressure limit value again during the re-docking process of the radio frequency interface on the lower end face of the TR component 17 and the radio frequency interface on the antenna array surface 20, the fixed multi-core connector on the lower end face of the TR component 17 and the floating multi-core connector on the antenna array surface, the control arm stops the downward insertion action, and moves the TR component 17 upward to make the radio frequency interface on the lower end face of the TR component 17 and the radio frequency interface on the antenna array surface 20, the fixed multi-core connector on the lower end face of the TR component 17 and the floating multi-core connector on the antenna array surface disengage, controls the vertical drive cylinder 6 to move the TR component 17 upward to make its top end face abut against the positioning protrusion on the horizontal positioning plate 19, vertically fixes the TR component 17, controls the mechanical arm to move the vision device to check the coaxiality between the radio frequency interface on the lower end face of the TR component 17 and the KK connector 21, if the coaxiality meets the requirements, returns to step eight, if the coaxiality does not meet the requirements, controls the mechanical arm to send the TR component 17 and the KK connector 21 to the recycling tray for subsequent manual recycling, and returns to step one until all the TR components 17 are assembled on the active phased array radar antenna array surface 20.
