Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a signal docking apparatus and a signal docking system.
Background
In the field of communication, a great deal of signal testing is required when communication equipment is manufactured. Before signal testing, the communication equipment needs to be moved to a designated place and is in signal butt joint with a testing instrument.
For large-scale communication equipment, such as 5G AAU (Active Antenna Unit), the volume and weight are large, the weight generally exceeds 45KG, and the length is close to 1 meter, in order to reduce the labor intensity of workers, the AAU is placed on a turnover vehicle, and the turnover vehicle is jacked up by a latent jacking type AGV and sent to a specified process. (Note: the latent jacking AGV is an automatic trolley which runs according to a preset route, and the use method of the AGV is to enter the lower part of a transported object, jack the transported object up and carry the transported object to a specified place.)
Although the use of a latent lift AGV is a very flexible automated turnaround approach that has been developed in recent years, it presents challenges to the automated docking of signal lines during AAU testing. Because the positioning accuracy of the latent jacking AGV is +/-10 mm, the turnover vehicle is of a welded structure, the size error reaches +/-5 mm, and all sides of the turnover vehicle have distortion, inclination and other angle errors. Therefore, if this technique is adopted, the AAU can only be lifted off the turnover vehicle and placed on a dedicated tray with higher accuracy, and automatic docking of the signal lines can be realized.
Specifically, several signal docking approaches commonly used in the prior art are analyzed as follows:
1) and (4) manual wiring. The disadvantages of this approach are: the labor intensity of operators is high, and the safety problem of live insertion and extraction of the operators in the wiring and disconnection processes and the product quality problem caused by misoperation of the operators cannot be avoided.
2) The manipulator clamps the cable instead of manual wiring. The disadvantages of this approach are: the realization cost is higher, a mechanical arm needs to be purchased, a 3D intelligent camera and customized software need to be purchased in a matched mode, and a special wire clamping jaw is developed.
3) And a universal transfer cart or a universal tray is used for realizing automatic signal butt joint. The disadvantages of this approach are: the contour consistency of the turnover vehicle and the universal tray is poor, and a size error exists, and the size error can finally cause the position deviation and the angle deviation of the mounting surface of the butting connector, so that the normal butting of signals is influenced.
4) The communication equipment is switched to the special tray, and automatic signal butt joint is realized through the special tray. The disadvantages of this approach are: a special tray can only correspond the AAU of a model, and special tray must join in marriage automatic assembly line and just can realize automatic butt joint, and automatic assembly line investment is big, and in case establish, will carry out rebuilding, extension, removal to the assembly line, all must stop the line construction, and is far less nimble than the mode that jacking formula AGV transported turnover vehicle. In addition, the allowable axial deviation of the existing special tray butt joint method is less than +/-3 mm, the allowable angle deviation is within +/-1 degree, and the difficulty of butt joint operation is increased due to small tolerance.
Therefore, a signal docking apparatus and a signal docking system are needed to solve the above problems.

Referring to fig. 1 to fig. 3, an embodiment of the present application provides a signal docking apparatus 100, which can be used for signal docking during production test of large equipment (e.g., 5G AAU) in the communication field. The signal docking device 100 can correct the position offset and the angle deviation between the device to be tested 300 and the testing device 200 before signal docking, and improve the efficiency of signal docking.
The signal docking device 100 of the present embodiment includes a mounting substrate 1, an adjustment mechanism 3, and a connector module 4. Wherein the mounting substrate 1 is a mounting base for each component, preferably, the mounting substrate 1 of the present embodiment is a square frame structure, and the side of the frame is provided with a lug for being fixedly connected with the transferring tool 400 through a screw. The connector module 4 is used for signal interfacing with the test instrument 200, and the connector module 4 includes a wire connection portion for electrically connecting with the device under test 300 and a signal interfacing portion 43 for signal interfacing with the test instrument 200. The adjustment mechanism 3 is elastically connected between the connector module 4 and the mounting substrate 1. The adjusting mechanism 3 includes a position adjusting mechanism and an elastic restoring mechanism, wherein the position adjusting mechanism is configured to enable the connector module 4 to move in the X-axis, Y-axis and Z-axis directions relative to the mounting substrate 1 under the action of an external force, and enable the connector module 4 to rotate around the X-axis, Y-axis and Z-axis directions relative to the mounting substrate 1 under the action of the external force; the elastic restoring mechanism is configured to be able to restore the connector module 4 with respect to the mounting substrate 1. In this embodiment, the X-axis direction refers to a direction in which the connector module 4 moves left and right, the Y-axis direction refers to a direction in which the connector module 4 moves up and down, and the Z-axis direction refers to a direction in which the connector module 4 moves forward and backward.
Specifically, the signal docking device further includes two side mounting frames 2 provided on one side of the mounting substrate 1 at an interval. The two side mounting frames 2 are arranged along the X-axis direction and are respectively located on two opposite side frames of the mounting substrate 1. In this embodiment, to realize the movement of the connector module 4 along the X-axis direction, the position adjustment mechanism includes a first sliding rod 31 and a sliding block 32, the first sliding rod 31 is installed between the two side installation frames 2 along the X-axis direction, and the sliding block 32 is installed on the first sliding rod 31 in a sliding manner. Since the connector module 4 is connected to the mounting substrate 1 through the adjusting mechanism 3, when the connector module 4 is subjected to an external force, the connector module 4 can slide along the first slide bar 31 along with the slide block 32, so as to adjust the position of the connector module 4 in the X-axis direction. Further, the elastic restoring mechanism of the present embodiment includes first elastic members 33, the first elastic members 33 are disposed in pairs, and each pair of the first elastic members 33 respectively penetrate through two ends of the first sliding rod 31 and are located between the sliding block 32 and the side mounting frame 2. In the present embodiment, the first elastic member 33 is preferably a spring, both ends of which are respectively in contact with the slider 32 and the side mounting frame 2, and the connector module 4 can be held at the initial position without receiving an external force by the elastic force of the spring. Preferably, the initial position is a central position of the mounting substrate 1, so that the signal docking device 100 is more uniform in all directional tolerances.
Fig. 4 shows a schematic front view of the signal docking device 100 in the embodiment of the present application. Referring to fig. 1 to 4, in the present embodiment, a support plate 41 is preferably fixedly disposed on a surface of the mounting substrate 1 facing the adjusting mechanism 3. The support plates 41 are provided in pairs, and each pair of support plates 41 is arranged in the Y-axis direction. In this embodiment, in order to realize the movement of the connector module 4 along the Y-axis direction, the position adjustment mechanism further includes a second slide bar 34, the second slide bar 34 is disposed along the Y-axis direction, the second slide bar 34 is slidably disposed through the slide block 32, and two ends of the second slide bar 34 are respectively fixedly connected to the support plates 41 on two sides. The signal docking apparatus 100 of the present embodiment can enable the slider 32 to slide along the second sliding bar 34 when the connector module 4 receives an external force, so that the connector module 4 can also move along the Y-axis direction with respect to the mounting substrate 1. The elastic recovery mechanism further includes second elastic members 35, the second elastic members 35 are also arranged in pairs, and each pair of the second elastic members 35 respectively penetrates through two ends of the second sliding rod 34 and is located between the sliding block 32 and the supporting plate 41. The second elastic member 35 enables the connector module 4 to be maintained at the initial position without being subjected to an external force. The second elastic member 35 is also preferably a spring in this embodiment.
With continued reference to fig. 4, preferably, in this embodiment, two first slide bars 31 and two second slide bars 34 are provided, forming a "well" shape. Specifically, two first slide bars 31 are arranged at intervals along the Y-axis direction, and two second slide bars 34 are arranged at intervals along the X-axis direction; the intersection of the first slide bar 31 and the second slide bar 34 is provided with one sliding block 32, that is, the number of the sliding blocks 32 is four, and the four sliding blocks 32 are arranged in a rectangular array. The above arrangement increases the balance of the signal docking apparatus 100, makes the movement of the connector module 4 more stable, and facilitates the movement of the connector module 4 along multiple directions and angles. In order to further increase the stability and reliability of the signal docking device and prevent the slide block 32 from deflecting, as shown in fig. 3 and 4, each second sliding rod 34 of the present embodiment has a dual-rod structure, and the dual-rod structure simultaneously penetrates through the same slide block 32.
With continued reference to fig. 2 and 3, in order to realize the rotation of the connector module 4 around the Z-axis direction, the position adjustment mechanism of the embodiment further includes first sliding grooves 321 disposed on the sliding blocks 32, the length of the first sliding grooves 321 extends along the Y-axis direction, and the first sliding rods 31 are movably disposed in the first sliding grooves 321, so that the sliding blocks 32 can move along the Y-axis direction relative to the first sliding rods 31. Referring to fig. 4, by providing the four first sliding grooves 321, when the connector module 4 is subjected to an external force, a rotational inclination (e.g., one side of the connector module 4 moves up along the Y-axis and the other side moves down along the Y-axis) can be generated in a plane parallel to the mounting substrate 1, so that an angular deviation of the connector module 4 rotating around the Z-axis direction can be eliminated when signals are mated. Further, the first sliding slot 321 can also realize the movement of the connector module 4 in the Y-axis direction (for example, the connector module 4 drives the four sliding blocks 32 to move up along the Y-axis simultaneously, or move down along the Y-axis simultaneously). In addition, the elastic recovery mechanism further includes a third elastic member, the third elastic member is disposed in the first sliding groove 321 along the Y-axis direction and is abutted against the first sliding rod 31, and the third elastic member enables the first sliding rod 31 to be at the initial position without being subjected to an external force. Further, as shown in fig. 3, each sliding block 32 is connected to a first mounting block 36, and a groove for mounting the third elastic member is formed in the first mounting block 36, and the groove is communicated with the first sliding groove 321 to form an accommodating space for the third elastic member. Preferably, the third elastic member is also a spring.
With continued reference to fig. 3, in order to realize the rotation of the connector module 4 around the X-axis direction and the Y-axis direction, the position adjustment mechanism of the present embodiment further includes second sliding grooves 21 disposed on each side mounting frame 2, wherein each side mounting frame 2 is opened with two second sliding grooves 21, and the length direction of the second sliding grooves 21 extends along the Z-axis direction. Both ends of the first slider bar 31 are mounted in the second slide groove 21, so that the first slider bar 31 can move in the Z-axis direction with respect to the mounting substrate 1. In this embodiment, when the same ends of the two first sliding bars 31 both retreat along the Z-axis direction and the other ends of the two first sliding bars 31 both advance along the Z-axis direction, the connector module 4 can rotate around the Y-axis direction; when both ends of one first slide bar 31 advance along the Z-axis direction and both ends of the other first slide bar 31 retreat along the Z-axis direction, the rotation of the connector module 4 around the X-axis direction can be realized. Therefore, by providing the four second sliding grooves 21, the connector module 4 can be turned over with respect to the mounting substrate 1 when receiving an external force, and angular deviations of the connector module 4 in the X-axis direction and the Y-axis direction can be eliminated when signal mating is performed. Further, the second slide grooves 21 also enable the movement of the connector module 4 as a whole in the Z-axis direction (for example, two first slide bars 31 advance along the Z-axis simultaneously or retreat along the Z-axis simultaneously in the four second slide grooves 21). In addition, the elastic recovery mechanism further includes a fourth elastic member, the fourth elastic member is disposed in the second sliding slot 21 along the Z-axis direction and is abutted against the first sliding rod 31, and the fourth elastic member enables the first sliding rod 31 to be in the initial position without being subjected to an external force. Furthermore, a second mounting block 37 is further connected to a position, corresponding to the second sliding groove 21, of each side mounting frame 2, a groove for mounting a fourth elastic member is formed in the second mounting block 37, and the groove is communicated with the second sliding groove 21 and used for forming an accommodating space for the fourth elastic member. Here, the second mounting block 37 can also play a certain limiting role, so as to prevent the side mounting frame 2 from moving too far along the Z-axis. Preferably, the fourth elastic member is also a spring.
With the above structure, the signal docking device 100 can eliminate axial deviations of the connector module 4 in the X-axis direction, the Y-axis direction and the Z-axis direction and angular deviations rotating around the X-axis direction, the Y-axis direction and the Z-axis direction, i.e. deviations of 6 degrees of freedom, before the connector module 4 is docked with the test instrument 200, thereby further increasing the tolerance of the signal docking device 100 and improving the adaptability of the device during signal docking.
In this embodiment, the specific value of the deviation that can be eliminated by the signal docking device 100 depends on the following design parameters: the length of the first elastic member 33, the length of the second elastic member 35, the length of the first slide groove 321, and the length of the second slide groove 21. Illustratively, the axial movement distance of the connector module 4 in this embodiment is ± 15mm, and the angular deflection range is ± 10 degrees. At this time, the lengths of the first elastic member 33 and the second elastic member 35 are designed to be 60mm, and the lengths of the first slide groove 321 and the second slide groove 21 are designed to be 30 mm. Because the allowable axial deviation of the existing special tray docking technology is less than +/-3 mm, and the allowable angular deviation is within +/-1 degree, the special tray docking technology is far ahead of the special tray docking technology in terms of tolerance. The scheme that the manipulator clamps the cable is not different from the application in tolerance, but the cost is high, the cost of 1 six-axis manipulator is about 50 thousands, the cost of 1 3D intelligent camera (including software) is about 20 thousands, the application totally adopts structural parts, the cost of batch processing can be controlled at 500 yuan/set, each set of the application can be butted with a product of a rotary vehicle, and the advantage of the application in cost is obvious through comprehensive calculation.
