Description

Technical Field

[0001] This utility model belongs to the field of test fixture technology, specifically relating to a multi-station test fixture for radio frequency modules. Background Technology

[0002] RF modules, or radio frequency modules, are an indispensable part of modern wireless communication. They are widely used in vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, community paging, industrial data acquisition systems, wireless tags, identification, contactless RF smart cards, small wireless data terminals, security and fire protection systems, wireless remote control systems, biosignal acquisition, hydrological and meteorological monitoring, robot control, wireless RS232 data communication, wireless RS485 / RS222 data communication, digital audio, and digital image transmission.

[0003] During the processing of RF modules, the finished workpieces need to be tested, which requires the use of test fixtures. However, existing test fixtures only have one station. Therefore, after testing a product, it is necessary to unload the product and then load it. This does not allow for efficient testing with multiple stations and has certain limitations in use. To address this, we propose a multi-station test fixture for RF modules. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station test fixture for radio frequency modules, so as to solve the problem that the existing test fixtures mentioned in the background art only have one station. Therefore, after testing a product, it is necessary to unload the product and then load it. This makes it impossible to use multi-station high-efficiency testing and has certain limitations in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station testing fixture for radio frequency modules, comprising a base, several bolts passing through the base, a mounting shell fixedly mounted on the upper surface of the base, a motor fixedly mounted inside the mounting shell, a rotating shaft fixedly mounted at the output shaft end of the motor, a sliding sleeve slidably disposed on the outer surface of the rotating shaft, a rotating disk fixedly mounted on the outer surface of the sliding sleeve, several station plates mounted in a circular array on the upper surface of the rotating disk, a motor fixedly mounted on the side of the station plate, a bidirectional screw rotatably mounted inside the station plate, the output shaft of the motor being fixedly connected to one end of the bidirectional screw, threaded plates threadedly mounted on the outer surfaces of both ends of the bidirectional screw, connecting plates fixedly mounted at both ends of the threaded plates, the same station fixture fixedly mounted at the ends of two connecting plates on the same side, and a channel for the movement of the connecting plates being opened on the side of the station plate.

[0006] The above solution utilizes a motor in conjunction with a rotating shaft, a rotating disk, and multiple workstation plates on the rotating disk. The motor drives the rotating shaft to rotate the disk, thereby enabling the switching and adjustment of multiple workstation plates and facilitating multi-station testing. After testing a product, only the position needs to be switched, ensuring good testing efficiency. Furthermore, the bidirectional screws on the workstation plates, in conjunction with workstation clamps, securely hold the RF modules in place, preventing them from wobbling or shifting during testing and ensuring smooth and accurate testing. A sliding sleeve, in conjunction with an adjusting rod and spring, allows for vertical adjustment of the rotating plate, enabling height adjustment according to testing needs and improving versatility. The lighting strip provides illumination in low-light conditions, ensuring smooth testing.

[0007] In the above scheme, it should be noted that the motor, the light bar, and the lamp are all electrically connected to an external power source.

[0008] In a preferred embodiment, an anti-slip pad is attached to the lower surface of the base, and a through hole is provided on the anti-slip pad at the position of the bolt, through which the bolt passes.

[0009] By adopting the above solution and setting anti-slip pads, the base can be installed without slipping, which improves installation stability and prevents the bolts from squeezing and damaging the installation surface when they are screwed in, thus providing a safety protection effect.

[0010] In a preferred embodiment, the outer surface of the mounting shell is provided with an annular groove, and a plurality of arc-shaped sliders are slidably mounted on the inner wall of the annular groove. A guide sleeve is fixedly mounted on the surface of the arc-shaped slider, and a guide rod is slidably mounted on the guide sleeve. The top end of the guide rod is fixedly connected to the rotating disk.

[0011] Using the above scheme, when the rotating shaft rotates and drives the rotating disk to rotate through the sliding sleeve, the rotating disk will drive the arc-shaped slider to slide in the annular groove through the guide rod and guide sleeve. When the sliding sleeve drives the rotating disk to slide up and down on the surface of the rotating shaft to adjust its position, it will move up and down synchronously through the guide rod in the guide sleeve. In this way, by using the guide rod and guide sleeve in conjunction with the arc-shaped slider, the rotating disk has good motion stability and avoids the phenomenon of shaking.

[0012] In a preferred embodiment, a plurality of limiting strips are fixedly installed on the outer surface of the rotating shaft, and a plurality of limiting grooves are provided on the inner wall of the sliding sleeve, with the limiting strips and limiting grooves used in conjunction.

[0013] Using the above solution, the limiting strip is used in conjunction with the limiting groove, which can ensure that the sliding sleeve can rotate synchronously when the rotating shaft rotates, and also ensure that there is no horizontal movement when the sliding sleeve moves up and down for adjustment.

[0014] In a preferred embodiment, an adjusting rod is slidably mounted on the sliding sleeve, an adjusting disc is fixedly mounted on one end of the adjusting rod, a spring is fixedly mounted between the adjusting disc and the sliding sleeve, and a plurality of adjusting grooves are formed on the outer surface of the rotating shaft, with the other end of the adjusting rod cooperating with the adjusting grooves.

[0015] Using the above scheme, when the adjusting rod slides out of the adjusting groove, the spring deforms, and at this time the sliding sleeve is unlocked and can slide up and down on the rotating shaft surface to adjust the height position. After the height position is adjusted, the spring force drives the adjusting rod to quickly return to the adjusting groove, thus achieving convenient operation and adjustment.

[0016] In a preferred embodiment, a plurality of support rods are fixedly installed on the inner wall of the workstation plate, and the threaded plate is slidably installed on the outer surface of the plurality of support rods.

[0017] By adopting the above scheme, the support rod can support and guide the movement of the threaded plate, improve the stability of the movement, and prevent swaying.

[0018] In a preferred embodiment, the side of the workstation fixture is attached with an anti-slip sponge pad, and two anti-slip sponge pads are arranged opposite each other on the workstation plate.

[0019] By adopting the above solution, the anti-slip sponge pad can provide a fixed and anti-slip effect when the RF module is fixed and clamped, and can also provide a protective effect when the RF module is fixed, avoiding direct contact between the workstation fixture and the RF module, which could cause squeezing damage.

[0020] In a preferred embodiment, a mounting column is fixedly installed at the top of the rotating shaft, and a plurality of lighting strips are fixedly installed on the surface of the mounting column, the lighting strips being used in conjunction with the workstation plate.

[0021] Using the above solution, the lighting strips can provide illumination and ensure good brightness in the space.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This RF module uses a multi-station test fixture, which is equipped with a motor, a rotating shaft, a rotating disk, and multiple workstation plates on the rotating disk. The motor drives the rotating shaft to rotate the rotating disk, thereby realizing the switching and adjustment of multiple workstation plates, and thus enabling multi-station testing. After testing a product, you only need to rotate to switch positions, ensuring good testing efficiency. Furthermore, the bidirectional screws on the workstation plates are used in conjunction with the workstation clamps to fix and clamp the RF module, ensuring that the RF module will not shake or shift during the test, and ensuring that the test operation is carried out smoothly and accurately.

[0024] This RF module uses a multi-station test fixture with a sliding sleeve, adjusting rod, and spring. The rotating plate can be adjusted up and down, and the height of the station plate can be adjusted according to the test requirements, improving its versatility. The lighting strip can provide illumination when the space is not bright enough, ensuring that the test can be carried out smoothly. Attached Figure Description

[0031] Please see Figure 1-5 This utility model provides a multi-station testing fixture for radio frequency modules, including a base 1, with several bolts 2 passing through the base 1. A mounting shell 3 is fixedly installed on the upper surface of the base 1. A motor 4 is fixedly installed inside the mounting shell 3. A rotating shaft 5 is fixedly installed at the end of the output shaft of the motor 4. A sliding sleeve 6 is slidably arranged on the outer surface of the rotating shaft 5. A rotating disk 7 is fixedly installed on the outer surface of the sliding sleeve 6. Several station plates 8 are installed in a circular array on the upper surface of the rotating disk 7. A motor 9 is fixedly installed on the side of the station plate 8. A bidirectional screw 10 is rotatably installed inside the station plate 8. The output shaft of the motor 9 is fixedly connected to one end of the bidirectional screw 10. Threaded plates 11 are threadedly installed on the outer surface of both threads of the bidirectional screw 10. Connecting plates 12 are fixedly installed at both ends of the threaded plates 11. The same station clamp 13 is fixedly installed at the ends of the two connecting plates 12 on the same side. A channel for the movement of the connecting plates 12 is opened on the side of the station plate 8.

[0032] By using a motor 4 in conjunction with a rotating shaft 5, a rotating disk 7, and multiple workstation plates 8 on the rotating disk 7, the motor 4 drives the rotating shaft 5 to rotate the rotating disk 7, thereby enabling the switching and adjustment of multiple workstation plates 8 and achieving multi-station testing. After testing a product, only the position needs to be switched, ensuring good testing efficiency. Furthermore, the bidirectional screw 10 on the workstation plate 8, in conjunction with the workstation clamp 13, securely clamps the RF module, ensuring that the RF module will not wobble or shift during testing and ensuring smooth and accurate testing. By using a sliding sleeve 6 in conjunction with an adjusting rod 19 and a spring 21, the rotating plate can be adjusted up and down, thereby adjusting the height of the workstation plate 8 according to testing needs, improving versatility. The lighting strip 25 provides illumination when the space is dimly lit, ensuring smooth testing.

[0033] An anti-slip pad 14 is attached to the lower surface of the base 1. The anti-slip pad 14 has a through hole at the position of the bolt 2. The bolt 2 passes through the through hole. By setting the anti-slip pad 14, the base 1 can be installed with an anti-slip effect, which improves the installation stability. At the same time, it can prevent the bolt 2 from being squeezed and damaged when it is screwed into the installation surface, thus providing a safety protection effect.

[0034] An annular groove is formed on the outer surface of the mounting shell 3, and several arc-shaped sliders 17 are slidably mounted on the inner wall of the annular groove. A guide sleeve 15 is fixedly mounted on the surface of the arc-shaped slider 17, and a guide rod 16 is slidably mounted on the guide sleeve 15. The top end of the guide rod 16 is fixedly connected to the rotating disk 7. When the rotating shaft 5 rotates, it drives the rotating disk 7 to rotate through the sliding sleeve 6. The rotating disk 7 will drive the arc-shaped sliders 17 to slide in the annular groove through the guide rod 16 and the guide sleeve 15. When the sliding sleeve 6 drives the rotating disk 7 to slide up and down on the surface of the rotating shaft 5 to adjust its position, it will move up and down synchronously through the guide rod 16 in the guide sleeve 15. In this way, the guide rod 16 and the guide sleeve 15 are used in conjunction with the arc-shaped sliders 17 to make the rotating disk 7 have good motion stability and avoid the phenomenon of shaking.

[0035] Several limiting strips 18 are fixedly installed on the outer surface of the rotating shaft 5, and several limiting grooves are opened on the inner wall of the sliding sleeve 6. The limiting strips 18 are used in conjunction with the limiting grooves. The use of the limiting strips 18 in conjunction with the limiting grooves can ensure that the sliding sleeve 6 can rotate synchronously when the rotating shaft 5 rotates, and can also ensure that the sliding sleeve 6 will not have horizontal movement when it moves up and down for adjustment.

[0036] An adjusting rod 19 is slidably mounted on the sliding sleeve 6. An adjusting disc 20 is fixedly mounted on one end of the adjusting rod 19. A spring 21 is fixedly mounted between the adjusting disc 20 and the sliding sleeve 6. Several adjusting grooves are opened on the outer surface of the rotating shaft 5. The other end of the adjusting rod 19 is used in conjunction with the adjusting groove. When the adjusting rod 19 slides out of the adjusting groove, the spring 21 deforms. At this time, the sliding sleeve 6 is unlocked and can slide up and down on the surface of the rotating shaft 5 to adjust the height position. After the height position is adjusted, the elastic force of the spring 21 drives the adjusting rod 19 to quickly return to the original position and insert into the adjusting groove, so as to achieve convenient operation and adjustment.

[0037] Several support rods 22 are fixedly installed on the inner wall of the workstation plate 8. The threaded plate 11 is slidably installed on the outer surface of the several support rods 22. The support rods 22 can support and guide the movement of the threaded plate 11, improve the movement stability, and prevent shaking.

[0038] Anti-slip sponge pads 23 are attached to the side of the workstation clamp 13. Two anti-slip sponge pads 23 are arranged opposite each other on the workstation plate 8. The anti-slip sponge pads 23 can provide a fixed anti-slip effect when the RF module is fixed and clamped, and can also provide a protective effect when the RF module is fixed, avoiding direct contact between the workstation clamp 13 and the RF module to prevent squeezing damage.

[0039] A mounting post 24 is fixedly installed at the top of the rotating shaft 5. Several lighting strips 25 are fixedly installed on the surface of the mounting post 24. The lighting strips 25 are used in conjunction with the workstation plate 8. The lighting strips 25 can provide lighting to ensure good brightness in the space.

[0040] In use, the base 1 is installed and fixed using bolts 2. The height of the rotating disk 7 is adjusted according to the test requirements. During adjustment, pulling the adjusting disk 20 drives the adjusting rod 19 to move away from the adjusting groove. At this time, the spring 21 deforms and the sliding sleeve 6 unlocks. Holding the rotating disk 7, the sliding sleeve 6 slides up and down on the surface of the rotating shaft 5. After adjusting to the appropriate height position, the adjusting disk 20 is released. At this time, the adjusting rod 19 will return to its original position under the action of the spring 21 and insert into the adjusting groove to lock. Then, the RF module to be tested is placed on the surface of the workstation plate 8 and positioned between the two workstation fixtures 13. The motor 9 is started to drive the bidirectional screw 10 to rotate. This drives the threaded plate 11 to move the station fixture 13 through the connecting plate 12. The relative movement of the two station fixtures 13 achieves the fixing and clamping of the RF module. The RF modules on the station plates 8 at other positions are fixed and clamped in sequence. Then, the motor 4 is started to drive the rotating shaft 5 to rotate. The rotating shaft 5 drives the rotating disk 7 to rotate through the sliding sleeve 6, which in turn drives the station plate 8 to rotate, thereby driving the fixed RF module to rotate. When an RF module rotates to the test point of the test equipment, the motor 4 is stopped, and then the test is carried out. After the test is completed, the motor 4 is started again to realize the position switching of the station plate 8, achieving the multi-station test effect.
