Description

Technical Field

[0001] The present invention mainly relates to the technical field of microwave antennas, and particularly to a multi-row SMP double-female connector continuous feeding and grasping mechanism. Background Art

[0002] As a core interconnection component in a phased array radar system, the SMP double-female connector is widely used in the high-frequency signal transmission between T / R modules and antenna arrays due to its excellent radio frequency performance, such as a working frequency band covering DC~40GHz, low insertion loss, stable impedance matching, and a compact mechanical structure, ensuring high-precision beam control and low-noise signal processing of the radar system.

[0003] With the development of modern phased array radars towards ultra-large-scale arrays (such as shipborne, spaceborne, and ground-based early warning radars) and high-density integration, the number of T / R channels in a single antenna array has increased exponentially from hundreds in the early stage to thousands or even tens of thousands. This has led to an exponential growth in the assembly demand for SMP double-female connectors. Taking a certain type of airborne active phased array radar as an example, more than 5,000 SMP double-female connectors need to be installed on a single array surface. If the traditional manual installation method is used one by one, the assembly man-hours for a single array surface may be as long as 30~50 man-days, severely restricting the mass production efficiency of the radar system.

[0004] In addition, the manual installation mode also has the following key problems: Poor assembly consistency: Due to individual differences among operators, the insertion depth dispersion can reach ±0.2mm, easily resulting in poor contact or over-tightening of the connector, affecting the stability of signal transmission; High risk of lateral force: Statistical data shows that about 12%~18% of on-site failures are due to lateral stress during manual installation, which further leads to signal reflection (VSWR≥1.5) or even mechanical failure; Insufficient traceability: It is difficult to accurately record the installation parameters (such as assembly depth) of each connector during manual operation, which is not conducive to later maintenance and fault diagnosis.

[0005] These problems not only greatly increase the debugging and maintenance costs of the radar system but also may lead to a decrease in the detection accuracy of the entire radar due to the performance degradation of individual connectors, affecting the combat effectiveness. Therefore, developing an efficient and high-precision assembly scheme has become a key technical bottleneck for improving the mass production capacity and reliability of phased array radars. Summary of the Invention

[0006] The object of the present invention is to provide a multi-row SMP double-female connector continuous feeding and grasping mechanism, which comprises two main parts: a feeding support and a quick handle.

[0007] To achieve the above object, the present invention provides a multi-row SMP double-female connector continuous feeding and grasping mechanism, including a feeding support and a quick handle; The feeding support includes a groove plate, a baffle, a support, a rotating shaft and a knob; The groove plate is a flat plate provided with horizontally-arrayed slots. The spacing of the horizontally-arrayed slots on the groove plate is the same as the installation spacing of the SMP double-female connectors, and is used to quickly pick up the SMP double-female connectors and arrange them in an array; the rotating shaft is provided with openings having the same array spacing as the groove plate in the horizontal direction, the knob is arranged at both ends of the rotating shaft, and the rotating shaft is driven by the knob; the baffle is used to guide the SMP double-female connectors into the openings on the rotating shaft; the support in the feeding support is a structural member, which is used to fix the groove plate, the baffle, the rotating shaft and the knob, so that the feeding support remains stable during operation; The quick handle includes a handle, a support and a socket; the handle is used for holding during installation; the bottom of the socket is provided with openings having the same array spacing as the groove plate in the horizontal direction, and after grasping the SMP double-female connectors row by row from the rotating shaft, all the connectors are synchronously installed in place in a row; the support in the quick handle is a structural member, which is used to fix the handle and the socket.

[0008] Further, the slots and openings with the same array spacing on the groove plate, the rotating shaft and the socket are fixed slots, fixed holes or detachable molds having the same array spacing of slots and openings.

[0009] Further, groove plates, rotating shafts and sockets with various array spacings can be processed for replacement to adapt to different SMP connector installation spacings.

[0011] Further, a conveyor belt is further included, and the conveyor belt is arranged at the position where the support in the feeding support contacts the groove plate to realize the continuous feeding of SMP double-female connectors.

[0020] In this example, 24 SMP double-female connectors are fed in one time, and 8 are grabbed and installed in a row at one time. The specific implementation method is as follows: A multi-row SMP double-female connector continuous feeding and grabbing mechanism consists of a feeding support and a quick handle.

[0021] As Figure 1 shown, the feeding support is composed of a groove plate 11, a baffle 12, a support 13, a rotating shaft 14, a knob 15, etc., and is used to realize the continuous feeding of SMP double-female connectors; The groove plate 11 is an aluminum plate with horizontally arrayed grooves. Every 8 of the 24 grooves form a group, and the spacing is the same as the installation spacing of the SMP double-female connector. Groove plates with various spacings can be processed for replacement to adapt to different connector installation spacings.

[0022] The baffle 12 is a transparent organic glass plate, which is used to guide the SMP double-female connectors arranged in an array into the fixing holes on the rotating shaft. Its transparent structure is conducive to observing the position and state of the SMP double-female connectors during continuous feeding.

[0023] The support 13 is assembled by 6 aluminum plates and is used to fix the groove plate 11, the baffle 12, the rotating shaft 14 and the knob 15, so that the feeding support can be kept stable during operation.

[0024] The rotating shaft 14 is an aluminum column with arrayed holes and is driven by the knob 15. The hole positions correspond one by one to the grooves on the groove plate 11.

[0025] When using the feeding support, first horizontally insert the groove plate 11 into a large number of SMP double-female connectors. When taking it out, quickly smooth the surface connectors to make them arranged in an array in the grooves, as Figure 3 shown; slowly tilt the groove plate and place it on the support 13, and adjust the knob 15 to make the SMP double-female connectors slide into the round holes on the rotating shaft 14 under the action of gravity, as Figure 4 shown, to realize the continuous feeding of SMP double-female connectors.

[0026] The quick handle is as Figure 2 shown and is composed of a handle 21, a support 22, a socket 23, etc., and is used to realize the quick row-by-row grabbing and installation of SMP double-female connectors; The handle 21 is an aluminum cylinder and is held when in use; The support 22 is an aluminum structural member and is used to fix the handle 21 and the socket 23; The socket 23 is an aluminum structural member with arrayed holes at the bottom, and the hole spacing is the same as the hole spacing of the rotating shaft 14 and the installation spacing of the SMP double-female connector.

[0027] When using the quick handle to pick and install in rows, first adjust the rotating shaft 14 so that all connectors are vertically upward. Align the array of round holes at the bottom of the socket 23 with the SMP double-female connector, and insert it vertically to the bottom to pick up in rows, as Figure 4 shown. Then insert it vertically to the bottom at the designated position and slowly pull it out, as Figure 5 and Figure 6 shown. Picking and installing in rows like this can ensure the perpendicularity and depth consistency of the connector insertion, and reduce connector failures caused by improper installation.

[0028] The key point of the described example is that it is necessary to accurately control the array opening sizes on the rotating shaft 14 and the socket 23: (1) If the array opening size on the rotating shaft 14 is too large, the position accuracy and perpendicularity of the SMP double-female connector are poor, which is not conducive to picking in rows; if the opening size is too small, the SMP double-female connector is not easy to accurately slide into the rotating shaft, and the friction between the connector and the rotating shaft is too large, and it is not easy to disengage from the rotating shaft when picking in rows; (2) If the array opening size on the socket 23 is too large, the friction between the socket and the SMP double-female connector is insufficient, and the connector is easy to fall off when picking and moving in rows; if the opening size is too small, the friction between the socket and the SMP double-female connector is too large, and when the connector is installed in place, it is easy to loosen when pulling out the socket; (3) Referring to the connector manual, it can be known that the separation force of the SMP connector ≥ 2.2N. Based on this, design the array opening size on the socket 23, and then design the array opening size on the rotating shaft 14 with reference to the array opening size on the socket. After repeated iterations in combination with the actual use effect, the double-female connector is a structure with two different thicknesses (there is a step), one section has a diameter of φ3.2 and the other section has a diameter of φ3.4. Determine the two opening sizes on the socket (corresponding to the two steps of the SMP double-female connector) to be φ3.4 (+0.03, +0.07) and φ3.2 (+0.03, +0.07) respectively, and the opening size on the rotating shaft is φ3.7 (0, +0.05); the bottom of the socket can also be set as a stepped hole, with φ3.4 on the outside and φ3.2 on the inside, corresponding to the connector. Embodiment 2

[0029] This embodiment is basically the same as Embodiment 1, except that the support 13 in the feeding support can be set horizontally or inclined.

[0030] The multi-row SMP double-female connector continuous feeding and picking mechanism in this embodiment further includes a conveyor belt, and the conveyor belt is arranged at the position where the support in the feeding support contacts the groove plate to realize the continuous feeding of the SMP double-female connector.

[0031] The present invention provides a multi-row SMP double-female connector continuous feeding and grasping mechanism, which is used to assist the rapid installation of SMP double-female connectors. After proficiently using this mechanism, the installation efficiency of SMP double-female connectors is increased by about 10 times compared with the traditional method; when using this mechanism to assist in the installation of SMP double-female connectors, the insertion perpendicularity and depth consistency of SMP double-female connectors can be effectively guaranteed, and connector failures caused by improper installation can be reduced.
