Description

Technical Field

[0001] The present invention relates to the field of testing technology, and in particular to a testing device for a data transmitter. Background Art

[0002] In the process of electronic equipment development and production, data transmitters often need to be tested. Data transmitter testing is an important part of ensuring data transmission quality and performance. The main purpose of data transmitter testing is to evaluate the performance, stability and reliability of data transmitters to ensure that they can transmit data efficiently and accurately in various environments.

[0003] The prior art still has the following deficiencies when testing data transmitters:

[0004] 1. Most existing test devices implement testing by directly connecting the plug end of the data transmitter to the test device, and when making the connection, the staff generally needs to manually plug and unplug the plug. However, during the manual plugging and unplugging process, the force direction may be offset, and frequent plugging and unplugging can easily cause damage to the plug, which in turn causes poor contact between the test device and the data transmitter, ultimately affecting the accuracy of the test;

[0005] 2. When connecting the data transmitter to the test device, in order to ensure that the data transmitter does not affect the detection accuracy due to vibration during the detection, it needs to be fixed. However, the fixing method of the data transmitter in the prior art is not stable enough and is relatively cumbersome.

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Example 1

[0043] Reference Figure 1-Figure 3 , a test device, which is used in the field of test equipment, includes a frame 1, two conveyor rollers 2 are rotatably connected inside the frame 1, two conveyor belts 3 are drivingly connected to the outer walls of the two conveyor rollers 2 for transmitting the data transmitter, a cylinder 6 is provided above the frame 1 and between the two conveyor belts 3, a placement plate 8 is provided above the cylinder 6 for lifting the data transmitter to move upward, support arms 15 are fixed on both sides of the top of the frame 1, a top plate 16 is welded between the two support arms 15, and a stable top platform is provided for testing the data transmitter.

[0044] Reference Figure 8 and Fig. 9A plurality of mounting plates 40 are provided below the top plate 16. A plurality of plug connectors 42 are installed on one side of each of the mounting plates 40. The plug connectors 42 match the plug connector ends of the data transmitter and are used for test connection of the data transmitter.

[0045] Reference Figure 2-Figure 5 In order to realize the clamping and fixing of the data transmitter, the present device is designed with a first clamping structure and two groups of second clamping structures. The first clamping structure includes a plurality of plug rods 9 fixed to the bottom of the placement plate 8. A bottom plate 5 is slidably sleeved on the outer wall of these plug rods 9. A plurality of first springs 10 are fixed between the bottom plate 5 and the placement plate 8. These first springs 10 are sleeved on the outer wall of the plug rods 9. Two stoppers 11 are fixed on one side of the top of the bottom plate 5 for blocking the data transmitter. A cushion block 7 is fixed to the bottom of the bottom plate 5. The output shaft of the cylinder 6 is fixedly connected to the bottom of the cushion block 7. Two first sliding grooves 12 are provided in the bottom plate 5. A first clamping plate 13 is slidably connected in each of the two first sliding grooves 12. A connecting rod 14 is rotatably connected to the side of the two first clamping plates 13 close to the cushion block 7. These connecting rods 14 are rotatably connected to the adjacent plug rods 9 and are located below the bottom plate 5. When the plug rod 9 moves downward, it will cooperate with the connecting rod 14 to drive the first clamping plate 13 to move.

[0046] Specifically, when the cylinder 6 pushes the bottom plate 5 and the placement plate 8 upward through the pad 7, the placement plate 8 will lift the data transmitter upward until the data transmitter touches the bottom of the top plate 16. At this time, the pad 7 will continue to push the data transmitter upward to reduce the distance between the bottom plate 5 and the placement plate 8. The first spring 10 is compressed, and the cooperation between the insertion rod 9 and the connecting rod 14 will pull the first clamping plate 13 toward the direction of the data transmitter. The first clamping plate 13 and the stop block 11 will initially clamp and fix the data transmitter.

[0047] Reference Figure 6 and Figure 7The second clamping structure includes two second slide grooves 21, each of which is slidably connected to a second clamping plate 23, and each of which slides through a plurality of sliding rods 22. These sliding rods 22 are respectively fixed in the corresponding second slide grooves 21, and the outer walls of the plurality of sliding rods 22 are sleeved with second springs 24, one end of each of the second springs 24 is fixedly connected to one side of the second clamping plate 23, and the other end is fixed to the inner wall of one side of the second slide groove 21. The cooperation between the second clamping plate 23 and the second spring 24 is used to clamp the data transmitter, and the two second clamping plates 23 are close to each other on one side. A trapezoidal rod 25 is fixed, and a top rod 17 is slidably inserted into the top plate 16. A trapezoidal plate 20 is fixed on both sides of the top rod 17. The top and bottom of these trapezoidal plates 20 are provided with inclined surfaces. The cooperation between the trapezoidal rod 25 and the trapezoidal plate 20 is used to control the movement of the second clamping plate 23. A cross plate 18 is fixedly sleeved on the outer wall of the top rod 17. A tension spring 19 is fixed on both sides of the bottom of the cross plate 18. The bottom ends of the two tension springs 19 are fixedly connected to the top of the top plate 16. The tension force of the tension spring 19 is greater than the elastic force of the second spring 24, which is used to drive the second clamping plate 23 to move outward when the top rod 17 moves downward.

[0048] Specifically, when the data transmitter pushes the top rod 17 to move upward, the tension spring 19 begins to stretch. As the trapezoidal plate 20 moves upward, the trapezoidal rod 25 touches the inclined surface at the bottom of the trapezoidal plate 20 and moves toward the middle under the elastic force of the second spring 24, thereby allowing the second clamping plate 23 to further clamp the data transmitter. The cooperation of the second clamping plate 23, the first clamping plate 13 and the block 11 fixes the data transmitter from multiple directions, which is convenient for the subsequent precise cooperation between the plug connector 42 and the plug end of the data transmitter.

[0049] Reference Figure 6 , Figure 8 and Fig. 9 In addition, two plug-in structures and a cooling structure are provided in the top plate 16. The plug-in structure is used to connect the plug connector 42 with the plug-in end of the data transmitter to complete the test connection of the data transmitter; the cooling structure is used to cool the data transmitter during the test to ensure the stability of the test process and the performance of the data transmitter.

[0050] Reference Figure 8 and Fig. 9The plug-in structure includes two third slide grooves 32 arranged in the top plate 16, and a common U-shaped frame 33 is slidably connected in the two third slide grooves 32. An electric push rod 34 is fixed on the top of the top plate 16, and the output shaft of the electric push rod 34 is fixedly connected to one side of the U-shaped frame 33. A rotating shaft 35 rotates through the U-shaped frame 33, and a rotating roller 37 is fixedly sleeved on the outer wall of the rotating shaft 35. A plurality of mounting plates 40 are arranged in a ring shape on the outer wall of the rotating roller 37, and a plug connector 42 is installed on each mounting plate 40. By rotating the rotating shaft 35, the rotating roller 37 and the mounting plate 40 can be driven to rotate, thereby replacing different plug connectors 42.

[0051] Specifically, during the test, the output shaft of the electric push rod 34 will drive the U-shaped frame 33 and the rotating roller 37 to move in the direction of the data transmitter, so that the plug connector 42 can accurately match with the plug end of the data transmitter, thereby completing the electrical connection between the data transmitter and the data transmission tester 4. The data transmission tester 4 is connected to the data transmitter through the plug connector 42 to send and receive test data to evaluate the performance and stability of the data transmitter. Since the electric push rod 34 pushes the U-shaped frame 33 to move in one direction, damage to the ports of the plug connector 42 and the data transmitter can be avoided, thereby extending the service life of the plug connector 42.

[0052] Reference Figure 8 and Fig. 9 In order to fix the mounting plate 40 on the outer wall of the rotating roller 37, the outer wall of the rotating roller 37 is provided with multiple groups of fixing structures, each group of fixing structures includes multiple threaded rods 38 fixed on the outer wall of the rotating roller 37, one end of these threaded rods 38 passes through the same mounting plate 40, and the outer walls of the multiple threaded rods 38 are fixedly sleeved with a retaining ring 39 for limiting the mounting plate 40. In addition, the outer walls of the multiple threaded rods 38 are threadedly sleeved with nuts 41, and the nuts 41 cooperate with the retaining ring 39 to clamp and fix the mounting plate 40.

[0053] Specifically, when the mounting plate 40 or the plug connector 42 needs to be replaced, the nut 41 only needs to be loosened to release the clamping of the mounting plate 40, so that the mounting plate 40 and the plug connector 42 can be conveniently disassembled for replacement.

[0054] Reference Figure 8The test device also includes a cooling structure for cooling the data transmitter, the cooling structure includes a ventilation slot 26 arranged in the top plate 16, and a plurality of hollow aluminum blocks 27 are fixed in the ventilation slot 26 from left to right in sequence, the bottoms of these hollow aluminum blocks 27 are flush with the bottom of the top plate 16, so that the data transmitter can contact the bottom of the hollow aluminum block 27, a same connecting pipe 28 is fixed between two adjacent hollow aluminum blocks 27, and the two adjacent hollow aluminum blocks 27 are connected by the connecting pipe 28, a cooling water tank 29 is fixed on the top of the top plate 16, a water pump 30 is fixed on one side of the cooling water tank 29, a liquid inlet end of the water pump 30 is connected to the cooling water tank 29 through a pipeline, and a liquid outlet end of the water pump 30 is connected to the hollow aluminum block 27 located on the far right through a pipeline, a circulation pipe 31 is fixed on the top of the cooling water tank 29, and one end of the circulation pipe 31 is connected to the hollow aluminum block 27 on the far left, so that the coolant in the cooling water tank 29 can circulate in the plurality of hollow aluminum blocks 27.

[0055] Reference Figure 8 Specifically, during the test, when the data transmitter contacts the bottom of the hollow aluminum block 27, the hollow aluminum block 27 will absorb the heat energy of the data transmitter and transfer it to the coolant inside it. At the same time, the operation of the water pump 30 will cause the coolant to circulate between the hollow aluminum block 27 and the cooling water tank 29, thereby ensuring that the coolant can effectively absorb heat energy and take away heat, thereby achieving cooling of the data transmitter.

[0056] Reference Figure 1 On one side of the rack 1, a data transmission tester 4 is firmly fixed by a mounting frame. The data transmission tester 4 is electrically connected to a plurality of plug connectors 42, which are designed to be connected to a data transmission device, thereby realizing a data transmission test function.

[0057] Reference Figure 8 Furthermore, in order to enhance the flexibility of the device, a rotatable structure is provided on the frame 1 in this embodiment. Specifically, a U-shaped frame 33 is fixed on the frame, and two damping bearings 36 are passed through and fixed in the U-shaped frame 33. Both ends of the rotating shaft 35 pass through the two damping bearings 36 respectively. Such a design enables the rotating shaft 35 to maintain a stable position after rotation and is not easy to shake.

[0058] In summary, this embodiment optimizes the data transmitter testing device by designing structures such as the rotating shaft 35, the sliding groove 43, the screw 44, the moving block 45, the U-shaped plate 48 and the cleaning component, which not only improves the accuracy and efficiency of the test, but also enhances the flexibility and practicality of the device.

[0061] Specifically, the cleaning component includes a first suction head 49 and two second suction heads 51. The first suction head 49 is fixed to an inner wall on one side of the U-shaped plate 48, and the two second suction heads 51 are respectively fixed to the top inner wall and the bottom inner wall of the U-shaped plate 48. A first suction pipe 50 connected to the first suction head 49 is fixedly passed through the U-shaped plate 48. At the same time, two second suction pipes 52 are fixedly passed through the top and bottom of the U-shaped plate 48. One ends of the two second suction pipes 52 are respectively connected to the two second suction heads 51, and the other ends are connected to the first suction pipe 50, and the first suction pipe 50 is connected to an external suction pump.

[0062] In actual operation, the motor drives the screw rod 44 to rotate, and the screw rod 44 drives the moving block 45 and the U-shaped plate 48 to move along the sliding groove 43. During the movement, the suction pump starts to work, and the dust on the plug connector 42 can be removed through the cooperation of the first suction pipe 50, the second suction pipe 52, the first suction head 49, and the second suction head 51. This design not only ensures the stability of the connection between the data transmitter and the plug connector 42 in the later stage, but also greatly improves the accuracy and efficiency of the test.

[0063] A method for using a testing device for a data transmission device, comprising the following steps:

[0064] S1, the conveying roller 2 and the conveying belt 3 cooperate to convey the data transmitter to one side, the block 11 limits the data transmitter, the cylinder 6 pushes the bottom plate 5 and the placement plate 8 upward through the cushion block 7, the placement plate 8 lifts the data transmitter upward until the data transmitter touches the bottom of the top plate 16, and the cushion block 7 continues to push the data transmitter upward, the distance between the bottom plate 5 and the placement plate 8 is reduced, the first spring 10 is compressed, the insertion rod 9 and the connecting rod 14 cooperate to pull the first clamping plate 13 toward the data transmitter, and the first clamping plate 13 and the block 11 preliminarily clamp and fix the data transmitter;

[0065] S2. In addition, when the data transmitter moves upward, the data transmitter pushes the push rod 17 upward, the tension spring 19 begins to stretch, and the push rod 17 simultaneously drives the trapezoidal plate 20 upward. As the trapezoidal plate 20 moves upward, the trapezoidal rod 25 touches the inclined surface at the bottom of the trapezoidal plate 20, and the trapezoidal rod 25 moves toward the middle under the elastic force of the second spring 24, so that the second clamping plate 23 can further clamp the data transmitter, and the cooperation of the second clamping plate 23, the first clamping plate 13 and the stopper 11 fixes the data transmitter from multiple directions, so as to facilitate the precise cooperation between the plug connector 42 and the plug end of the data transmitter in the later stage;

[0066] S3, the output shaft of the electric push rod 34 drives the U-shaped frame 33 and the rotating roller 37 to move toward the data transmitter, and the plug connector 42 can precisely match with the plug end of the data transmitter to complete the electrical connection between the data transmitter and the data transmission tester 4. The data transmission tester 4 is connected to the data transmitter through the plug connector 42 to send and receive test data to evaluate the performance and stability of the data transmitter; the test data may include data packets of different rates, different lengths, and different formats to simulate the data transmission scenario in the real environment; the data transmission tester 4 will record and analyze key indicators such as data transmission rate, delay, throughput, bit error rate, etc. to evaluate the performance of the data transmitter;

[0067] S4. Since the electric push rod 34 pushes the U-shaped frame 33 to move in one direction, damage to the plug connector 42 and the port of the data transmitter can be avoided, thereby ensuring the life of the plug connector 42. When the plug connector 42 is damaged, the rotating shaft 35 can drive the rotating roller 37 to rotate and replace a new batch of plug connectors 42 to ensure the normal operation of subsequent tests. In addition, by loosening the nut 41, the clamping of the mounting plate 40 is released, and the mounting plate 40 and the plug connector 42 can be disassembled and replaced at a later stage.

[0068] S5. During the test, the data transmitter touches the bottom of the hollow aluminum block 27. The hollow aluminum block 27 absorbs the heat energy of the data transmitter and is absorbed by the coolant in the hollow aluminum block 27 to cool the data transmitter. In addition, the operation of the water pump 30 can circulate the coolant in the hollow aluminum block 27 and the cooling water tank 29 to ensure that the coolant can effectively absorb heat energy.

[0069] S6. In addition, in order to ensure the stability of the connection between the plug connector 42 and the data transmitter, it is necessary to remove the dust on the plug connector 42; specifically, the motor drives the screw rod 44 to rotate, and the screw rod 44 drives the moving block 45 and the U-shaped plate 48 to move along the sliding groove 43. During the movement, the suction pump can remove the dust on the plug connector 42 through the cooperation of the first suction pipe 50, the second suction pipe 52, the first suction head 49, and the second suction head 51, so as to ensure the stability of the subsequent connection.

[0070] However, as is well known to those skilled in the art, the working principles and wiring methods of the cylinder 6, data transmission tester 4, water pump 30 and electric push rod 34 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
