Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency chip detection, and particularly relates to a fixture for radio frequency chip detection. Background Art

[0002] A radio frequency chip refers to a chip used to synthesize a baseband signal to be transmitted or decode a received baseband signal. Specifically, when transmitting, voice or other data signals are encoded into a baseband code for transmission; when receiving, the received baseband code is decoded into voice or other data signals. When the radio frequency chip is produced, it needs to be tested to ensure the normal use of its subsequent functions.

[0003] When detecting, the chip needs to be fixed. At present, most traditional clamping tools are fixed, or only clamp chips of a certain size. When fixing chips of different sizes, the fixture needs to be replaced, and the fixed fixture is not convenient for workers to adjust the detection angle of the chip. Often, the chip needs to be removed from the fixture and re-clamped, thus affecting the detection work. Content of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a fixture for radio frequency chip detection, which solves the problems that the fixture needs to be replaced when fixing chips of different sizes, and the fixed fixture is not convenient for workers to adjust the detection angle of the chip.

[0005] To achieve the above object, the utility model provides the following technical scheme: A fixture for radio frequency chip detection, including a fixed base, fixed slots are opened on both sides of the fixed base, fixing plates are connected above both sides of the fixed base, a fixed rod is fixedly connected to the fixing plate on one side of the fixed base, a threaded rod is threadedly connected to the fixing plate on the other side of the fixed base, a hand wheel is connected to one end of the threaded rod, a main mounting sleeve is rotatably connected to the other end of the threaded rod, a secondary mounting sleeve is connected to one end of the fixed rod, and movable columns are rotatably connected inside the main mounting sleeve and the secondary mounting sleeve;

[0006] A main limiting plate is connected to the movable column inside the main mounting sleeve, a secondary limiting plate is connected to the movable column inside the secondary mounting sleeve, sliding slots are opened on both sides of the main limiting plate and the secondary limiting plate, a first spring is connected inside the sliding slots, the main limiting plate is connected to a main side plate through the first spring, a plug rod is connected to the main side plate, the secondary limiting plate is connected to a secondary side plate through the first spring, and a slot is opened on the secondary side plate.

[0007] As a further scheme of the utility model: A storage box is slidably mounted above the fixed base, an anti-slip pad is connected below the fixed base, and the storage box is located between the two fixing plates.

[0008] As a further solution of the present utility model: bottom plates are connected to the main limiting plate, the secondary limiting plate, the main side plate and the secondary side plate, and a rubber pad is connected to the opposite sides of the main limiting plate and the secondary limiting plate.

[0009] As a further solution of the present utility model: a second spring is connected inside the movable column. There are four second springs symmetrically centered on the axis of the movable column, and a clamping block is connected to one end of the second spring.

[0010] As a further solution of the present utility model: connecting blocks are connected to both sides of the main mounting sleeve, sliding rods are connected to the connecting blocks, and the sliding rods are slidably connected to the fixing plate.

[0011] As a further solution of the present utility model: clamping grooves are provided inside both the main mounting sleeve and the secondary mounting sleeve. There are eight clamping grooves evenly distributed in a centrally symmetric manner, and the clamping blocks slide inside the movable column and are engaged with the clamping grooves.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For the fixture for detecting radio frequency chips, by setting the handwheel, the threaded rod, the main side plate, the secondary side plate, the first spring, the sliding groove, the insertion rod and the insertion slot, the staff first rotates the threaded rod through the handwheel to increase the distance between the main mounting sleeve and the secondary mounting sleeve. At this time, the insertion rod will slide in the insertion slot. Then, the radio frequency chip is placed on the bottom plate. During the placement process, the chip will push the main side plate and the secondary side plate to slide in the sliding groove, stretching the first spring. Thus, the main side plate and the secondary side plate clamp the chip through the rebound of the first spring. Then, the threaded rod is rotated to make the main limiting plate approach the chip, so that the main limiting plate and the secondary limiting plate can clamp and fix the chip. The fixture can clamp and fix chips of different sizes through the movable main limiting plate, main side plate and secondary side plate, improving the applicability.

[0014] 2. For the fixture for detecting radio frequency chips, by setting the movable column, the second spring, the clamping block and the clamping groove, the staff pushes the main limiting plate and the secondary limiting plate to make the two movable columns rotate in the main mounting sleeve and the secondary mounting sleeve respectively. During the rotation, the clamping block will be squeezed into the inside of the movable column, causing the clamping block to compress the second spring. The resilience of the second spring can push the clamping block into the clamping groove to fix the movable column. The design of multiple clamping grooves in the main mounting sleeve and the secondary mounting sleeve enables the staff to adjust the detection angle of the chip at intervals of 45°, facilitating the staff to detect the chip.

Specific implementation mode

[0020] The technical solutions of this patent will be further described in detail below in conjunction with the specific implementation mode.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: a fixture for detecting a radio frequency chip, including a fixed base 1, fixed grooves 2 are opened on both sides of the fixed base 1, fixed plates 3 are connected to both sides above the fixed base 1, a storage box 19 is slidably installed above the fixed base 1, an anti-slip pad 20 is connected below the fixed base 1, the storage box 19 is located between the two fixed plates 3, and the friction between the fixed base 1 and the detection workbench is increased through the anti-slip pad 20, thereby improving the stability of the fixed base 1, and the storage box 19 can store and collect the radio frequency chips after detection.

[0022] A fixed rod 4 is fixedly connected to the fixed plate 3 on one side of the fixed base 1, a threaded rod 5 is threadedly connected to the fixed plate 3 on the other side of the fixed base 1, a handwheel 6 is connected to one end of the threaded rod 5, the other end of the threaded rod 5 is rotatably connected to a main installation sleeve 7, connecting blocks 24 are connected to both sides of the main installation sleeve 7, a sliding rod 25 is connected to the connecting blocks 24, and the sliding rod 25 is slidably connected to the fixed plate 3. When the threaded rod 5 pushes the main installation sleeve 7 to move, the sliding rod 25 will slide on the fixed plate 3, thereby guiding and restricting the main installation sleeve 7 to prevent the main installation sleeve 7 from rotating with the threaded rod 5.

[0023] One end of the fixed rod 4 is connected with a secondary mounting sleeve 8. An activity column 9 is rotatably connected in both the main mounting sleeve 7 and the secondary mounting sleeve 8. A second spring 22 is connected inside the activity column 9. There are four second springs 22 symmetrically centered on the axis of the activity column 9. One end of the second spring 22 is connected with a clamping block 23. By jointly inserting a plurality of clamping blocks 23 into a plurality of clamping grooves 26, the stability of the fixation of the activity column 9 is improved, and the accidental rotation of the activity column 9 is prevented.

[0024] A main limiting plate 10 is connected to the activity column 9 inside the main mounting sleeve 7, and a secondary limiting plate 11 is connected to the activity column 9 inside the secondary mounting sleeve 8. Clamping grooves 26 are provided in both the main mounting sleeve 7 and the secondary mounting sleeve 8. There are eight clamping grooves 26 evenly distributed in a centrosymmetric manner. The clamping block 23 slides inside the activity column 9 and is fitted with the clamping groove 26. Through the eight evenly distributed clamping grooves 26, the staff can rotate the activity column 9 at intervals of 45°, so as to adjust the detection angle, and the operation is simple, improving the adjustment efficiency.

[0025] Sliding grooves 12 are provided on both sides of the main limiting plate 10 and the secondary limiting plate 11. A first spring 13 is connected inside the sliding grooves 12. The main limiting plate 10 is connected with a main side plate 14 through the first spring 13. A plug rod 15 is connected to the main side plate 14. The secondary limiting plate 11 is connected with a secondary side plate 16 through the first spring 13. A slot 17 is provided on the secondary side plate 16. Bottom plates 18 are connected to the main limiting plate 10, the secondary limiting plate 11, the main side plate 14 and the secondary side plate 16. A rubber pad 21 is connected to the opposite side of the main limiting plate 10 and the secondary limiting plate 11. When the main limiting plate 10 and the secondary limiting plate 11 clamp and fix the chip, the rubber pad 21 will be squeezed, so as to fit with the chip to increase friction and prevent the chip from slipping when adjusting the detection angle.

[0026] The working principle of the present utility model is as follows:

[0027] The staff first rotates the threaded rod 5 through the hand wheel 6 to pull the main mounting sleeve 7, so as to expand the distance between the main limiting plate 10 and the secondary limiting plate 11. At this time, the plug rod 15 will slide in the slot 17. Then, the radio frequency chip is placed on the bottom plate 18. During the placement process, the chip will simultaneously push the main side plate 14 and the secondary side plate 16 to slide in the sliding groove 12, so as to stretch the first spring 13 by the main side plate 14 and the secondary side plate 16. Thus, the main side plate 14 and the secondary side plate 16 clamp the chip through the rebound of the first spring 13. Then, the threaded rod 5 is rotated to push the main limiting plate 10 close to the chip, so that the main limiting plate 10 and the secondary limiting plate 11 can clamp and fix the chip. The staff can push the main limiting plate 10 and the secondary limiting plate 11 to rotate the two activity columns 9 in the main mounting sleeve 7 and the secondary mounting sleeve 8 respectively. When rotating, the clamping block 23 will be squeezed into the inside of the activity column 9 to compress the second spring 22. The second spring 22 is used to make the clamping block 23 snap into the clamping groove 26 by its rebound, so as to fix the activity column 9 and complete the adjustment of the detection angle of the chip.
