Description

Technical Field

[0001] The present invention relates to the technical field of antenna detection equipment, and in particular to a batch screw tightening detection device and a detection method. Background Art

[0002] The solid-state phased array antenna (hereinafter referred to as the "antenna") needs to be equipped with three types of RF coaxial connectors. The antenna and the RF coaxial connector are connected by threads. The antenna mounting surface is a stepped hole. When installing the RF coaxial connector, it needs to be inserted into the corresponding hole and fastened using standard parts, such as Figure 1 As shown. In the production site, there are a large number of RF coaxial connectors that need to be assembled, and a large number of screws. The tightening state of the screws has a significant impact on the assembly quality. Due to the small space in the stepped hole, the automatic tightening and detection equipment cannot reach into the interior to tighten the screws. The level of employees in manual assembly varies. In order to ensure the assembly quality, it is particularly important to tighten the screws. At present, there are two main screw tightening detection methods:

[0003] Visual inspection by skilled personnel. This method requires skilled personnel to visually and through personal experience determine whether the screws are tightened and whether the spring washers are flattened, and ultimately determine the tightening degree of the screws and identify loose screws.

[0004] With the help of screw tightening detection tooling. Using the height difference between the screw and the antenna surface, a screw tightening detection tooling is designed. When in use, the tooling is inserted into the corresponding stepped hole. If the screw is tightened, the stepped surface of the tooling head fits the antenna surface exactly. If the screw is not tightened, there is a gap between the stepped surface of the tooling head and the antenna surface. Thus, the tightening status of the screw is determined.

[0005] At present, the above two traditional screw tightening detection methods both have some disadvantages. The first manual visual inspection method is highly subjective, has a low level of automation, low consistency, is prone to omissions, and is affected by environmental factors such as light. Although the second method uses tooling inspection, it can only inspect the tightening status of two screws at a time, which is inefficient. In addition, when the screws are not tightened, the gap is small and difficult to detect by visual observation, and there is also a risk of omission. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a batch screw tightening detection device and a detection method in view of the deficiencies in the prior art.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A batch screw tightening detection device comprises: a base plate, a plurality of positioning blocks for positioning screw positions, a plurality of detection components for detecting whether the screws are tightened, a plurality of first springs for abutting against an antenna, a plurality of diodes and a battery, wherein the plurality of positioning blocks, the plurality of first springs, the plurality of diodes and the battery are all mounted on the base plate, the plurality of detection components are mounted in the plurality of positioning blocks in a one-to-one manner and can be telescopically mounted in the plurality of positioning blocks, the top ends of the plurality of detection components are exposed on the outsides of the plurality of positioning blocks, the plurality of diodes are adjacent to the plurality of detection components in a one-to-one manner, one end of the plurality of diodes is connected to one end of the battery in a one-to-one manner, the other end of the plurality of diodes is connected to the plurality of detection components in a one-to-one manner, and the other end of the battery is connected to the first spring.

[0008] The beneficial effect of the technical solution of the present invention is that the length of the detection component exposed outside the positioning block is the length that just does not contact the detection component when the screw of the RF connector is tightened. If the screw of the RF connector is not tightened, the detection component contacts the screw, and the height difference is used to convert the contact between the detection component and the mounting screw of the RF connector into a switch. The detection component is used to detect whether it is in contact with the two mounting screws of the RF coaxial connector, and the light-emitting diode is used to observe the passage. When the screw is not tightened, the detection component abuts against the screw, and the battery, diode, detection component, screw, antenna, and first spring are connected to form a loop. The diode emits light to indicate that the screw is not tightened at this location. By connecting the positive poles of each diode in sequence, multiple loops can be formed in parallel with each other, and multiple loops can be detected at the same time. If the diode at one location emits light, the mounting screw of the RF connector corresponding to the diode at this location is not tightened, that is, the position of the untightened screw is identified. Batch rapid detection of screw tightening is achieved, and the positioning block is used to locate the position of the screw to be detected and fix the detection component. The consistency is improved with the help of structures such as the base plate, the positioning block, and the second spring.

[0009] Furthermore, the detection component includes: multiple probes and multiple second springs, the top ends of the multiple probes pass through the positioning block and are exposed on the outside, the multiple probes can be installed in the positioning block so as to slide up and down, the multiple second springs are correspondingly sleeved on the outsides of the multiple probes, the middle parts of the multiple probes are respectively provided with bosses, one end of the multiple second springs abuts against the bottom plate, the other ends of the multiple second springs abut against the multiple bosses one-to-one, the multiple second springs are connected to the other ends of the multiple diodes one-to-one, and the multiple diodes are adjacent to the multiple probes one-to-one.

[0010] The beneficial effect of adopting the above further technical solution is: the positioning block is used to locate the position of the screw to be detected and the fixation of the probe. The boss is used to lock the position to prevent the probe from sliding out of the positioning block. The second spring supports the probe so that its boss is against the upper end of the positioning block, and the protruding length of the probe is the length that just does not contact the probe when the screw of the RF connector is tightened. If the screw of the RF connector is not tightened, the probe contacts the screw, and the probe is used to detect whether it is in contact with the two mounting screws of the RF coaxial connector, and the light-emitting diode is used to observe the passage. Using the height difference, whether the probe is in contact with the mounting screw of the RF connector is converted into a switch of the electronic device. When in use, the positioning block of the device is placed in the stepped hole of the antenna, and the bottom plate contacts the surface of the antenna. When the screw is not tightened, the probe touches the mounting screw of the RF connector. The circuit starts from the positive electrode of the battery, passes through the positive and negative electrodes of the diode, the second spring inside the positioning block, the probe, the screw, the antenna, the first spring outside the positioning block, and finally returns to the negative electrode of the battery. A passage is formed, the diode emits light, and the untightened screw can be quickly located. The fast batch detection of screw tightening is realized. The positioning block is used to locate the position of the screw to be detected and fix the detection component. The consistency is improved with the help of structures such as the bottom plate, the positioning block and the second spring.

[0011] Furthermore, the plurality of probes are located on both sides of the top of the positioning block, the other ends of the plurality of second springs are respectively abutted against the bottom ends of the plurality of bosses, the top ends of the plurality of bosses are abutted against the top of the positioning block, and the first spring, the probes, and the second springs are all made of metal conductive material.

[0012] The beneficial effect of adopting the above further technical solution is that the probes are located on both sides of the top of the positioning block, which is convenient for adapting to the screws to be detected on the antenna. The setting of the second spring facilitates the extension and retraction of the probe and automatic resetting, prevents the detection of screws in other positions from being affected when one screw is not tightened, and improves the reliability and stability of detection. The first spring, the probe, and the second spring are all made of metal conductive materials to achieve the conductive function, so that when the screw is not tightened, the probe touches the mounting screw of the RF connector. The circuit starts from the positive electrode of the battery, passes through the positive and negative electrodes of the diode, the second spring inside the positioning block, the probe, the screw, the antenna, the first spring outside the positioning block, and finally returns to the negative electrode of the battery. A pathway is formed, the diode emits light, and the untightened screw can be quickly located.

[0013] Furthermore, the bottom plate is provided with a plurality of cylindrical holes, and the plurality of arc holes protrude from the end surface of the bottom plate. The bottom sides of the positioning block are buckled on the plurality of cylindrical holes, and the bottoms of the plurality of probes correspond one to one and can be slid up and down in the plurality of cylindrical holes.

[0014] The beneficial effects of adopting the above further technical solution are: the cylindrical hole is used to fix the positioning block and leave space for the probe to expand and contract, which facilitates the installation and maintenance of the positioning block and the probe, prevents the positioning block from shaking, and improves the stability and reliability of the batch screw tightening detection device.

[0015] Furthermore, the diode and the first spring are both located outside the positioning block, the first spring is vertically mounted on the bottom plate, and the bottom plate is a nylon plate.

[0016] The beneficial effects of adopting the above further technical solution are: the diode and the first spring are both located outside the positioning block, which is convenient for the user to observe whether the diode is emitting light, to find the position where the screw is not tightened through the diode, and to facilitate the first spring to dock with the antenna. The bottom plate is a nylon plate, which increases the load capacity of the bottom plate, extends the service life of the bottom plate, and reduces costs.

[0017] Furthermore, the top of the positioning block is a stepped structure, the stepped structure is adapted to the antenna stepped hole, and a guide hole for guiding the radio frequency coaxial connector is provided in the middle of the top of the positioning block.

[0018] The beneficial effects of adopting the above-mentioned further technical scheme are: the top of the positioning block is a stepped structure, which is convenient for adapting and docking with the antenna stepped hole, and convenient for accurately inserting the positioning block into the antenna stepped hole.

[0019] Furthermore, the bottom of the guide hole is connected to the base plate via bolts.

[0020] The beneficial effects of adopting the above-mentioned further technical solution are: facilitating the installation and maintenance of the positioning block, making the base plate and the positioning block removable and repeatedly installable, and by replacing different base plates and positioning blocks, it can be used for screw tightening detection of other models, thereby improving applicability, reducing costs, and being simple to operate and convenient to use.

[0021] Furthermore, the antenna is a phased array antenna, and a plurality of antenna step holes and a plurality of RF coaxial connectors are installed on the antenna, and the plurality of RF coaxial connectors are installed in the plurality of antenna step holes in a one-to-one correspondence with each other through screws.

[0049] The beneficial effect of the technical solution of the present invention is that the length of the detection component exposed outside the positioning block is the length that just does not contact the detection component when the screw of the RF connector is tightened. If the screw of the RF connector is not tightened, the detection component contacts the screw, and the height difference is used to convert the contact between the detection component and the mounting screw of the RF connector into a switch. The detection component is used to detect whether it is in contact with the two mounting screws of the RF coaxial connector, and the light-emitting diode is used to observe the passage. When the screw is not tightened, the detection component abuts against the screw, and the battery, diode, detection component, screw, antenna, and first spring are connected to form a loop. The diode emits light to indicate that the screw is not tightened at this location. By connecting the positive poles of each diode in sequence, multiple loops can be formed in parallel with each other, and multiple loops can be detected at the same time. If the diode at one location emits light, the mounting screw of the RF connector corresponding to the diode at this location is not tightened, that is, the position of the untightened screw is identified. Batch rapid detection of screw tightening is achieved, and the positioning block is used to locate the position of the screw to be detected and fix the detection component. The consistency is improved with the help of structures such as the base plate, the positioning block, and the second spring.

[0050] The diode is a light emitting diode. The diode can also be replaced by other warning and prompt components, such as a buzzer, a display screen, etc. The first spring is vertically mounted on the base plate, the bottom end of the first spring is connected to the negative pole of the battery, and the top end of the first spring is used to abut against the surface of the antenna. A plurality of positioning blocks are arranged in an array at one end of the base plate, and the positioning blocks of two adjacent rows in the upper and lower directions are staggered. The positioning block can be an elliptical structure.

[0052] The beneficial effect of adopting the above further technical solution is: the positioning block is used to locate the position of the screw to be detected and the fixation of the probe. The boss is used to lock the position to prevent the probe from sliding out of the positioning block. The second spring supports the probe so that its boss is against the upper end of the positioning block, and the protruding length of the probe is the length that just does not contact the probe when the screw of the RF connector is tightened. If the screw of the RF connector is not tightened, the probe contacts the screw, and the probe is used to detect whether it is in contact with the two mounting screws of the RF coaxial connector, and the light-emitting diode is used to observe the passage. Using the height difference, whether the probe is in contact with the mounting screw of the RF connector is converted into a switch of the electronic device. When in use, the positioning block of the device is placed in the stepped hole of the antenna, and the bottom plate contacts the surface of the antenna. When the screw is not tightened, the probe touches the mounting screw of the RF connector. The circuit starts from the positive electrode of the battery, passes through the positive and negative electrodes of the diode, the second spring inside the positioning block, the probe, the screw, the antenna, the first spring outside the positioning block, and finally returns to the negative electrode of the battery. A passage is formed, the diode emits light, and the untightened screw can be quickly located. The fast batch detection of screw tightening is realized. The positioning block is used to locate the position of the screw to be detected and fix the detection component. The consistency is improved with the help of structures such as the bottom plate, the positioning block and the second spring.

[0053] The second spring can be connected to the other end of the diode through a crimping terminal, and the probe is in contact with the second spring.

[0055] The beneficial effect of adopting the above further technical solution is that the probes are located on both sides of the top of the positioning block, which is convenient for adapting to the screws to be detected on the antenna. The setting of the second spring facilitates the extension and retraction of the probe and automatic resetting, prevents the detection of screws in other positions from being affected when one screw is not tightened, and improves the reliability and stability of detection. The first spring, the probe, and the second spring are all made of metal conductive materials to achieve the conductive function, so that when the screw is not tightened, the probe touches the mounting screw of the RF connector. The circuit starts from the positive electrode of the battery, passes through the positive and negative electrodes of the diode, the second spring inside the positioning block, the probe, the screw, the antenna, the first spring outside the positioning block, and finally returns to the negative electrode of the battery. A pathway is formed, the diode emits light, and the untightened screw can be quickly located.

[0060] The beneficial effects of adopting the above further technical solution are: the diode and the first spring are both located outside the positioning block, which is convenient for the user to observe whether the diode is emitting light, to find the position where the screw is not tightened through the diode, and to facilitate the first spring to dock with the antenna. The bottom plate is a nylon plate, which increases the load capacity of the bottom plate, extends the service life of the bottom plate, and reduces costs.

[0065] like Figures 1 to 12 As shown, further, the antenna 5 is a phased array antenna, and a plurality of antenna step holes 13 and a plurality of RF coaxial connectors 14 are installed on the antenna 5. The plurality of RF coaxial connectors 14 are installed in the plurality of antenna step holes 13 in a one-to-one correspondence through screws 2.

[0066] The beneficial effect of adopting the above further technical solution is that the setting of the antenna makes it easier for the batch screw tightening detection device to detect whether the screws at the position of the RF coaxial connector in the antenna are tightened.

A path is formed, the diode emits light, and the loose screw can be quickly located.

[0069] like Figures 1 to 12As shown, a batch screw tightening detection device includes a mechanical device and an electronic device. The electronic device is on the mechanical device, and the two devices cooperate with each other. The mechanical device includes a base plate and a positioning block, and the positioning block is screwed to the base plate. The electronic device includes a probe, a second spring, a diode, a power supply (battery) and a number of wires. The second spring and the probe are in the positioning block, and the diode and the first spring are distributed on the outside of the positioning block. The second spring and the probe inside the positioning block are in contact with the structure, the second spring is connected to the cathode of the diode through a wire, the anode of the diode is connected to the anode of the battery through a wire, the cathode of the battery is connected to the first spring on the outside of the positioning block through a wire, and the first spring on the outside of the positioning block is screwed on the base plate. Batch rapid detection of screw tightening is achieved, and consistency is improved with the help of mechanical devices.

[0070] Specifically, the present invention provides a batch screw tightening detection device, which is mainly divided into two parts: a mechanical device and an electronic device, including a base plate (1 piece), a positioning block (16 pieces), a probe (32 pieces), a spring (a first spring and a second spring totaling 34 pieces), a diode (32 pieces), a power source (battery), and a wire. Among them, there are 2 first springs and 32 second springs.

[0071] The mechanical device is mainly assembled by nylon parts. It includes a base plate (1 piece) and positioning blocks (16 pieces). The base plate is used for the basic support of the device. The base plate is made of 5mm thick nylon plate with 16 through holes. The guide blocks are installed at the positions of the through holes by bolts to fix the 16 positioning blocks. In addition, 32 protruding cylindrical holes are used to fix the positioning blocks and leave space for the expansion and contraction of the probe. The positioning block is used to locate the screw position and fix the probe. When in use, put the positioning block into the stepped hole of the antenna, the base plate contacts the surface of the antenna, and the first spring on the base plate contacts the antenna.

[0072] The electronic device is mainly composed of probes (32 pieces), a number of wires, diodes (32 pieces), springs (34 pieces), and a power source (battery). Two probes, two second springs, and two diodes are placed on each fixed block. The probe is made of a copper rod, and its structure is a cylinder with a boss for positioning. It is placed in the positioning block, and one end of the inside is inserted into the second spring. The second spring supports the probe so that its boss is against the upper end of the positioning block. The protruding length of the probe is the length that just does not touch the probe when the screws of the RF connector are tightened. If the screws of the RF connector are not tightened, the probe contacts the screws, so the probe is used to detect whether it contacts the two mounting screws of the RF coaxial connector, and the diode is used to observe the path. When a path is formed, the positive electrode of the battery is connected to the positive electrode of the diode through a wire, the negative electrode of the diode is connected to the second spring inside the positioning block through a wire, the second spring inside the positioning block and the probe are in contact through a structure, and when the RF connector mounting screws are not tightened, the probe is in contact with the mounting screws, and the mounting screws are assembled on the antenna, and they are all metal. The antenna is in contact with the first spring outside the positioning block, and the first spring outside the positioning block is connected to the negative electrode of the battery through a wire. At this point, the diode emits light.

[0073] Based on this principle, by connecting the positive poles of each diode in sequence, multiple circuits can be formed in parallel, and multiple circuits can be detected at the same time. If the diode at one place lights up, the RF connector mounting screw corresponding to the diode at that place is not tightened, that is, the position of the untightened screw is identified.

[0074] By combining mechanical devices with electronic devices, the mechanical device can quickly and accurately locate the positions of 32 screws. The electronic device uses the height difference to convert the contact between the probe and the mounting screw of the RF connector into a switch of the electronic device. When in use, place the positioning block of the device into the stepped hole of the antenna, and the base plate contacts the surface of the antenna. When the screw is not tightened, the probe touches the mounting screw of the RF connector. The circuit starts from the positive electrode of the battery, passes through the positive and negative electrodes of the diode, the second spring inside the positioning block, the probe, the screw, the antenna, the first spring outside the positioning block, and finally returns to the negative electrode of the battery. A pathway is formed, the diode emits light, and the untightened screws can be quickly located. 16 positioning blocks are installed on a base plate, which can quickly detect 32 screws in batches.

[0075] The base plate and the positioning block can be removed and installed repeatedly. By replacing different base plates and positioning blocks, it can be used for other types of screw tightening detection. The device is simple to operate and easy to use.

[0076] like Fig.13 As shown, in addition, the present invention also provides a batch screw tightening detection method, based on any one of the batch screw tightening detection devices described above, a batch screw tightening detection method includes:

[0077] S1. Place the positioning block into the antenna stepped hole;

[0078] S2, placing the bottom plate in contact with the antenna surface;

[0079] S3, placing the free end of the first spring in contact with the antenna;

[0080] S4. When the diode is lit, the screws at the LED are not tightened;

[0081] S5. When the diode does not emit light, the screws at the non-emitting diode have been tightened.

[0082] The beneficial effect of the technical solution of the present invention is: during detection, the positioning block is placed in the antenna stepped hole, the bottom plate contacts the antenna surface, the spring on the bottom plate contacts the antenna, and the length of the detection component exposed outside the positioning block is the length that just does not contact the detection component when the screw of the RF connector is tightened. If the screw of the RF connector is not tightened, the detection component contacts the screw, and the height difference is used to convert the contact between the detection component and the mounting screw of the RF connector into a switch. The detection component is used to detect whether it is in contact with the two mounting screws of the RF coaxial connector, and the light-emitting diode is used to observe the passage. When the screw is not tightened, the detection component abuts the screw, and the battery, diode, detection component, screw, antenna, and first spring are connected to form a loop, and the diode emits light to indicate that the screw is not tightened at that location. By connecting the positive poles of each diode in sequence, multiple loops can be formed in parallel, and multiple loops can be detected at the same time. If the diode at one location emits light, the mounting screw of the RF connector corresponding to the diode at that location is not tightened, that is, the position of the untightened screw is identified. Batch rapid detection of screw tightening is achieved, and the positioning block is used to locate the position of the screw to be detected and fix the detection component. The consistency is improved by means of structures such as a base plate, a positioning block and a second spring.

[0083] If the probe contacts the screw, the screw is a RF connector mounting screw whose tightening state needs to be detected.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
