Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] Antennas are crucial components in wireless radio frequency communications, used to transmit and receive radio wave signals. Antenna design and placement affect the transmission distance and quality of wireless communications. Radio frequency (RF) detection technology operates based on electromagnetic wave reception, signal processing, and data analysis. It converts electromagnetic waves (such as Wi-Fi, Bluetooth, and 5G signals) in the antenna receiving space into electrical signals, ultimately generating a spectrum to capture, measure, and analyze wireless signals.

[0039] During antenna manufacturing, wireless radio frequency detection is typically used to measure the antenna's ability to receive signals. However, this equipment is typically independent of the production line, preventing real-time feedback on process parameters and hindering continuous process design.

[0040] In view of this, the present application proposes a detection device that can be integrated into a wire body and adapted to the wire body's transfer tooling for positioning, thereby realizing automatic antenna processing and testing.

[0041] A transfer fixture specifically designed for the antenna assembly processing line is designed to operate on the line, allowing it to be integrated with welding and testing equipment. Specifically, the transfer fixture comprises a mounting base and multiple supporting units 30. The mounting base is designed to operate on the line. The supporting units 30 are spaced apart on the upper surface of the mounting base and are used to secure the antenna assembly's substrate, transmission lines, and terminals. Notches are partially provided in the supporting units 30 to expose the transmission lines and facilitate visual inspection.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 5 The inspection device includes a machine 1, an inspection module 2, and a positioning assembly 3. The machine 1 has an inspection station 10; the inspection module 2 is arranged at the inspection station 10. The inspection module 2 includes a test table 21, a probe (not shown), and a male terminal 23. The test table 21 is fixed to the machine 1 and is used to place a carrier unit 30 carrying an antenna assembly. Two test holes 22 are provided on the upper surface of the test table 21. The probe and the male terminal 23 can move in the vertical direction so as to be inserted into the corresponding test holes 22. The probe is used to contact the solder pad of the antenna assembly, and the male terminal 23 is used to be inserted into the female terminal of the antenna assembly; the positioning assembly 3 is used to fix the carrier unit 30 to the test table 21. It should be noted that when the carrier unit is circulated on the line, its height direction corresponds to the vertical direction; when the carrier unit 30 is placed in a horizontal state on the test table 21, the width direction of the carrier unit 30 corresponds to the vertical direction, and the length and height directions of the carrier unit 30 correspond to the horizontal direction.

[0043] In the technical solution of the present invention, the machine 1 is the machine 1 of the line body, the detection module 2 is located in the detection station 10, which can realize wireless radio frequency detection, the test table 21 plays a supporting function, and the work is loaded with a carrying unit 30 of a single antenna component. At this time, the substrate and transmission line in the antenna component are welded as one. Initially, the probe and the male terminal 23 are hidden on the lower side of the test table 21, which not only plays a protective role, but also avoids interference during the placement of the carrying unit 30. During the test, the probe and the male terminal 23 are both extended upward from the corresponding test hole 22, and the probe and the base in the antenna component are welded together. The male terminal 23 is used to be inserted into the female terminal at the other end of the transmission line in the antenna assembly, so that the wires and circuit board inside the detection module 2 form a circuit connection with the antenna assembly, so that the electromagnetic wave reception, signal processing and data analysis can be based on the wireless radio frequency detection principle to finally generate a spectrum diagram. The test spectrum diagram is compared with the standard spectrum diagram to give the detection result of the current antenna assembly. During the detection process, the carrier unit 30 is always fixed under the action of the positioning component 3, so as to ensure the precise positioning of the probe and the male terminal 23. This forms a coherent process with other equipment on the line body. Improve the degree of automation of antenna detection and processing.

[0044] The function of the detection module 2 can be realized by purchasing a wireless radio frequency detection instrument and connecting the corresponding part of the instrument to the probe and the male terminal 23 through a cable. The internal structure of the wireless radio frequency detection instrument will not be described in detail.

[0045] Specifically, the lifting and lowering drive structure of the probe and male terminal 23 is not limited and can be implemented by a cylinder, a lead screw, a connecting rod, or other structures. During the test process, the probe only needs to contact the pad to achieve the conduction effect, while the male terminal 23 requires a certain amount of force to be inserted into the female terminal when mating. In view of this, in some embodiments, the detection module 2 also includes a movable portion 24, which is movable in the vertical direction and penetrates one of the test holes 22; the male terminal 23 is mounted on the movable portion 24 via a floating structure 25. The provision of the floating structure 25 enables the male terminal 23 to float in the vertical direction, thereby relying on the floating structure 25 to buffer the driving force, and can provide a protective effect for the insertion of the male terminal 23 and the female terminal.

[0046] The present invention does not limit the specific form of the floating structure 25. Specifically, the male terminal 23 can be fixed by a clamp to facilitate the avoidance of the cable, and a spring is provided between the clamp and the movable part 24 to achieve a floating effect.

[0047] In this embodiment, please refer to Figure 4The floating structure 25 includes two mating plates 251 arranged in an upper and lower direction. The two mating plates 251 have through-holes on their sides facing each other for the connector 252 to pass through. The outer portion of the connector 252 located between the two mating plates 251 is sheathed with a spring. The upper and lower ends of the connector 252 protrude from the corresponding mating plates 251, and the upper and lower ends of the connector 252 are each provided with a limit baffle. The connector 252 cooperates with the two limit baffles to limit the maximum extension of the spring and keep the spring in a pre-stressed state. The mating plate 251 at the upper end is for mounting the male terminal, while the mating plate 251 at the lower end is connected to the drive component.

[0048] During the test process, the carrier unit 30 should be kept fixed relative to the test table 21. In some embodiments, the positioning assembly 3 includes a pressure plate 31, which is located on the upper side of the test table 21 and moves in the vertical direction. The pressure plate 31 has a range of motion to press the carrier unit 30 downward or move upward away from the carrier unit 30. The pressure plate 31 is driven by a lifting mechanism to move in the vertical direction. Initially, the pressure plate 31 moves upward away from the end surface of the test table 21. After the carrier unit 30 is placed in the designated position, the pressure plate 31 presses down to fix the carrier unit 30.

[0049] In some embodiments, the positioning assembly 3 further includes a plurality of positioning pins 32, which are fixed to the upper end surface of the test table 21 and spaced apart from the test holes 22. Each positioning pin 32 is configured to be inserted into a corresponding positioning hole on the carrier unit 30. The plurality of positioning pins 32 are used to define the horizontal position of the carrier unit 30. When the pressure plate 31 is provided, the plurality of positioning pins 32 cooperate with the pressure plate 31 to define the horizontal and vertical position of the carrier unit 30, thereby ensuring stability during testing.

[0050] The carrier unit 30 is placed vertically in its natural state, with the antenna assembly located above it, and the pads facing upwards. In order to adapt to the travel of the probe and the male terminal 23, the carrier unit 30 is placed horizontally on the test table 21, with the pads facing sideways and the female terminals facing the corresponding test holes 22. Based on this, the transmission line is affected by gravity, and the section in the gap may bend and sag. In wireless RF testing, it is necessary to ensure that the transmission line is in a straight state. In view of this, in this embodiment, please refer to Figure 1 and Figure 3The positioning assembly 3 further includes a wire retaining portion 33 movably mounted on the test bench 21 in a horizontal direction. The wire retaining portion 33 is used to press the transmission line of the antenna assembly against the notch of the carrier unit 30. After the carrier unit 30 is fixed, the wire retaining portion 33 is controlled to move so as to extend into the notch and push the transmission line sideways, thereby keeping the transmission line straight and fixed on the corresponding side of the carrier unit 30. During the test, the position of the wire retaining portion 33 is maintained, thereby maintaining the straight state of the transmission line and ensuring the detection accuracy.

[0051] In order to meet the requirements of appearance inspection while ensuring the positioning of the transmission line, multiple notches are usually provided, and the sizes of the multiple notches are set differently. Correspondingly, the line blocking portion 33 includes a main body 331 and a plurality of blocks 332 spaced apart at the lower end of the main body 331. The multiple blocks 332 are all used to contact the transmission line of the antenna assembly. The main body 331 has a connecting function. Corresponding to the side of the transmission line, the multiple blocks 332 extend into the multiple notches, thereby ensuring the overall straightness of the transmission line by flattening the transmission line at multiple points. The shape of each block 332 can be adapted to the notch. In some embodiments, the notch is a V-shaped groove, and each block 332 is set in a V-shape, so that it can rely on the inclined surface of the V-shaped structure for guidance and matching.

[0052] In this embodiment, two guiding inclined surfaces are formed at an angle on one side of each stopper 332 facing the carrying unit 30 . The two guiding inclined surfaces extend away from each other in a direction facing away from the carrying unit 30 .

[0053] In other embodiments, the wire blocking portion 33 may be fixed on the test bench 21 . After the carrying unit 30 is placed on the test bench 21 , the carrying unit 30 is moved to cooperate with the wire blocking portion 33 to achieve a positioning effect.

[0054] When the transfer tool is transferred to the detection device, it is placed vertically. In order to meet the detection requirements, the posture of the carrier unit 30 needs to be adjusted after the single carrier unit 30 is picked up. In this embodiment, please refer to Figures 5 and 6 The machine 1 also has a loading station 20, which is arranged horizontally with the inspection station 10. The loading station 20 is used to store a transfer tool with multiple load-bearing units 30. The inspection device also includes a transfer structure 4, which includes a transfer part 41. The transfer part 41 is movably mounted to the machine 1. The movable travel of the transfer part 41 passes through the loading station 20 and the inspection station 10. The transfer part 41 is used to pick up and transfer the load-bearing unit 30. The transfer part 41 is also used to drive the load-bearing unit 30 to rotate to adjust the load-bearing unit 30 from a vertical posture to a horizontal posture. The transfer part 41 can move in the vertical direction and the horizontal direction, and can rotate, thereby driving the load-bearing unit 30 to move and change its posture.

[0055] Specifically, after the transfer unit 41 picks up the carrier unit 30, it rotates the carrier unit 30 90 degrees during the transfer process, thereby achieving a posture change, keeping the carrier unit 30 in a horizontal position, and placing it in a designated position on the test table 21. If the test table 21 is provided with a positioning pin 32, the transfer unit 41 aligns the carrier unit 30 with the positioning pin 32 and then returns it to its original position.

[0056] The present invention does not limit the driving form of the transfer part 41. The transfer part 41 can be driven by a multi-axis manipulator, which can meet the transfer stroke, and can also drive the transfer part 41 to flip through the rotation of the multi-axis manipulator; it can also be achieved through a three-axis drive structure with a flip cylinder. At this time, the three-axis drive structure drives the transfer part 41 and the flip cylinder to move, and the flip cylinder drives the transfer part 41 to flip.

[0057] In order to realize the flipping function of the transfer part 41, please refer to the diagram. In this embodiment, the transfer structure 4 also includes a connecting seat, a driving cylinder and a connecting rod. The connecting seat includes a first connecting plate and a second connecting plate that are rotatably matched. The first connecting plate can be connected to the corresponding driving component, so that it is driven to move in the up and down directions and the horizontal direction. The driving cylinder is fixed on the first connecting plate, and the cylinder rod of the driving cylinder is set downward. The first connecting plate extends in the up and down directions, and its lower end is connected to the second connecting plate. The second connecting plate is fixed to the side of the first connecting plate that is back to the first connecting plate. A connecting hole extending in the up and down directions is provided on the second connecting plate to reveal a part of the transfer part 41. One end of the connecting rod is hinged to the lower end of the cylinder rod of the driving cylinder, and the other end of the connecting rod is hinged to the transfer part 41 through the connecting hole. During the extension and retraction process of the cylinder rod of the driving cylinder, the second connecting plate can be driven to rotate relative to the first connecting plate, thereby realizing the flipping action. The setting of the connecting rod can be compatible with the distance difference between the transfer part 41 and the cylinder rod.

[0058] For further information, please refer to Figure 6 The transfer unit 41 includes a mounting frame 411 and a clamping structure 412. The mounting frame 411 can be mounted to the machine 1 in both the vertical and horizontal directions. The clamping structure 412 can be rotatably mounted on the mounting frame 411 along an axis extending horizontally. The clamping structure 412 is used to clamp the carrier unit 30. The clamping structure 412 can be configured as a suction cup, a clamping claw 4121, or other structures. In this structure, the multi-directional drive of the transfer unit 41 is decomposed into different components, which facilitates the adjustment of the movable range of the transfer unit 41.

[0059] In order to improve the detection efficiency, two transfer parts 41 can be set up. The activities of the two transfer parts do not interfere with each other. When one transfer part 41 moves out the carrier unit that has completed the detection, the other transfer part 41 can place another carrier unit 30 on the test bench 21, thereby shortening the interval time between the two detections.

[0060] Since the bearing unit 30 has requirements for its posture before and after adjustment during the transfer process, the shaking problem of the bearing unit 30 needs to be considered during the transfer process. In this embodiment, the transfer part 41 includes a clamp structure 412, and the clamp structure 412 includes two clamping jaws 4121 arranged opposite to each other in the horizontal direction. The two clamping jaws 4121 have a movable stroke that moves closer to or away from each other. The two clamping jaws 4121 are provided with positioning columns 4122 on the sides facing each other. The surfaces of the positioning columns 4122 are provided with anti-rotation structures. The two positioning columns 4122 are used to be inserted into the corresponding positioning holes on the bearing unit 30. Specifically, when the two positioning columns 4122 are inserted and matched with the positioning blocks on both sides of the bearing unit 30, the movement of the two clamping jaws 4121 can drive the bearing unit 30 to move, and the bearing unit 30 will not rotate relative to the clamping jaws 4121 due to the anti-rotation structure during the movement, thereby ensuring the stability of the transfer of the bearing unit 30. Specifically, the positioning post 4122 can be a conventional cylindrical structure with a protrusion on its outer wall to form a rotation stop. The positioning post 4122 can be configured as a regular polygonal column such as a triangle or square, or can be configured as other irregular shapes so that the non-curved portion of its outer surface forms a rotation stop. The present invention is not limited to this. The positioning hole on the carrier unit 30 can be designed to match the positioning post 4122.

[0061] Since the detection device only detects one antenna component at a time, after one of the carrying units 30 is removed from the transfer tooling, the transfer tooling needs to wait at the loading station 20. In order to prevent the transfer tooling from flowing along the conveyor belt of the line, in some embodiments, the detection device also includes a lifting platform 5. The lifting platform 5 is located at the loading station 20 and is movably installed on the machine 1 in the up and down directions. By driving the lifting platform 5 upward, the transfer tooling with multiple carrying units 30 can be driven to separate from the line body and thus stay on the lifting platform 5. After completing the detection of all antenna components, the lifting platform 5 is controlled to fall back to drive the transfer tooling back to the conveyor belt so that it continues to flow. With this arrangement, the transfer tooling's stay at the detection station will not affect other stations of the entire line body, and the conveyor belt does not need to stop.

[0062] Furthermore, positioning pins may be provided on the lifting platform 5 to define the position of the transfer tool.

[0063] In some embodiments, the detection device further includes a limiting portion, which includes a base and multiple limiting pins disposed on the side of the base. The base is mounted on the machine 1 in a horizontally movable manner. During the movement of the base, the multiple limiting pins are used to insert into corresponding positioning holes on the side of a transfer tool having multiple bearing units 30 to determine the position of the transfer tool. By driving the base to move, the multiple limiting pins are driven to insert into the positioning holes of the transfer tool, and the transfer tool is stopped by lateral limiting.

[0064] Based on the above embodiment, a photoelectric sensor can be provided to detect the position of the transfer tool, thereby controlling the movement of the lifting platform 5 and / or the base. Alternatively, a stop bar can be provided to limit the movement of the transfer tool, and when the stop bar contacts the transfer tool, the movement of the lifting platform 5 and / or the base is controlled.

[0065] Considering processing efficiency, two parallel detection devices can be installed on the line body. Considering that the transfer tooling arrives at the two detection devices at different times, the processing of the two can be asynchronous. In this embodiment, two parallel conveyor belts are set up to simultaneously transport the transfer tooling. The two detection devices are located on the same side of the conveyor belts, and each detection device corresponds to one of the conveyor belts. Therefore, the movable travel of the transfer structure 4 in the two detection devices is different.

[0066] In an embodiment of the present invention, a chip is provided on the transfer tooling, which stores the serial number information of multiple carrier units 30 and can be recorded into the detection results via wireless transmission within a certain range. The detection method of the detection device is as follows:

[0067] Step S10: After the transfer tool moves to the designated position, the lifting platform 5 is controlled to move upward to separate the transfer tool from the line body, and at the same time, multiple limit pins are engaged with the transfer tool;

[0068] Step S20: Control the transfer unit 41 to move, grab one of the multiple carrier units 30 on the transfer tool, drive the carrier unit 30 to rotate from a vertical position to a horizontal position, and place the carrier unit 30 on the test table 21 while maintaining the horizontal position, so that the carrier unit 30 is inserted and engaged with the positioning pin 32;

[0069] Step S30 , controlling the transfer portion 41 to reset to fully expose the carrying unit 30 ;

[0070] Step S40 , controlling the pressing plate 31 to press the carrying unit 30 onto the test table 21 , and then controlling the wire blocking portion 33 to move to laterally support the transmission line;

[0071] Step S50 , controlling the probe and the male terminal 23 to move upward, so that the probe contacts the pad of the antenna assembly, and the male terminal 23 is inserted into the female terminal of the antenna assembly;

[0072] Step S60: Maintaining the preset time length allows the detection module 2 to output the spectrum diagram and obtain the detection result;

[0073] In step S70, the line blocking portion 33 and the pressure plate 31 are controlled to reset successively, and the transfer portion 41 is controlled to pick up the carrier unit 30, adjust the carrier unit 30 from a horizontal position to a vertical position, and place it back into the transfer fixture. At this time, the detection module 2 transmits the detection result of the corresponding carrier unit 30 to the chip and associates it with the number information of the corresponding carrier unit 30;

[0074] Repeat steps S10-S70 until all antenna assemblies on the carrying units 30 on the current transfer tool are inspected, and then control the lifting platform 5 and the base to reset so that the transfer tool can continue to flow.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, within the scope of the present invention are included in the patent protection scope of the present invention.
