Description

Technical Field

[0001] The present application relates to the field of oscilloscopes, and in particular to a workbench for an oscilloscope. Background Art

[0002] As a time domain electronic measuring instrument, oscilloscopes are widely used in the measurement field. Oscilloscopes can be seen everywhere, whether in the research and development, experiments, and training of electronic circuits and electronic information systems, or in production and manufacturing, fault diagnosis, and test and inspection.

[0003] In the prior art, a common oscilloscope mainly includes an oscilloscope body and a signal connection connected to the oscilloscope body, a power cord, a probe, etc. When an operator uses an oscilloscope for testing, he usually places the circuit board to be tested on a desktop where the oscilloscope is placed, and then tests the test points on the circuit board through the test probe.

[0004] However, when users debug a circuit board with the aid of an oscilloscope, they often place the circuit board to be tested on a desktop. In order to prevent the circuit board from being affected by the user's standing up movement, the circuit board to be tested often needs to be fixed on the desktop with tape. However, this method of fixing the circuit board to be tested is relatively cumbersome and easily causes contamination to the circuit board to be tested, and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience of fixing a circuit board when an operator uses an oscilloscope to debug the circuit board, the present application provides a workbench for an oscilloscope.

[0006] The present application provides an oscilloscope workbench that adopts the following technical solution:

[0007] A workbench for an oscilloscope comprises a table body, a bottom of the table body is provided with a receiving cavity, a loading plate is slidably connected in the receiving cavity, an adjustable clamping assembly for clamping a circuit board to be tested is mounted on the loading plate; and:

[0008] A sensing module, installed in the accommodating cavity, for sensing the movement of the carrier plate sliding out of the accommodating cavity and outputting a sensing signal;

[0009] The fill light is fixedly mounted on the platform, mounted above the object carrier, and has a signal input end connected to a signal output end of the sensing module for receiving the sensing signal and emitting light.

[0010] By adopting the above technical solution, when using an oscilloscope to test the circuit board to be tested, the operator can first pull out the carrier board in the accommodating cavity on the table body, and clamp and fix the circuit board to be tested through the adjustable clamping assembly on the carrier board, so as to achieve the technical effect of positioning and clamping the circuit board, and improve the convenience of the operator to test the circuit board to be tested. At the same time, through the mutual matching and use of the sensing module and the fill light, when the operator pulls out the carrier board, the sensing module outputs the sensing signal, and the fill light receives the sensing signal and emits light, providing the operator with a clear field of vision for the subsequent operation of testing the circuit board, and further improving the convenience of the operator to test the circuit board to be tested.

[0011] Preferably, two opposite inner side walls of the accommodating cavity are respectively provided with sliding grooves, and sliding parts are respectively fixedly connected to both sides of the loading plate. The two sliding parts are respectively embedded in the two sliding grooves, and anti-slip parts are respectively integrally formed at both ends of the two sliding grooves.

[0012] By adopting the above technical solution, the sliding parts on both sides of the carrier plate extend into the slide groove, and the operator can pull the carrier plate to make the carrier plate detach from the accommodating cavity to expose the adjustable clamping assembly, so that the operator can perform subsequent circuit board testing operations; and due to the provision of anti-detachment parts at both ends of the slide groove, the occurrence of the sliding part falling off the slide groove can be reduced, thereby improving the convenience of the operator in recovering the carrier plate.

[0013] Preferably, the bottom of the loading plate is fixedly connected with a support rod.

[0014] By adopting the above technical solution, the support rod can support the carrier board, thereby reducing the situation where the tilt of the carrier board causes the circuit board to be tested held by the carrier board to tilt.

[0015] Preferably, the adjustable clamping assembly comprises a first clamping plate and a second clamping plate, the first clamping plate is fixedly mounted on the carrier plate, the second clamping plate is adjustably mounted on the carrier plate, baffles are fixedly connected to the first clamping plate and the second clamping plate, and positioning plates are fixedly connected to opposite side walls of the two baffles;

[0016] The first clamping plate and the second clamping plate are respectively fixedly connected with spring pieces opposite to the positioning plate, and a positioning groove for clamping the side edge of the circuit board is formed between any of the opposite spring pieces and the positioning plate.

[0017] By adopting the above technical solution, during the installation of the circuit board, the operator can first extend one side of the circuit board to be tested into the positioning groove on the first clamping plate, and then the operator can slide the second clamping plate so that the side edge of the circuit board to be tested away from the first clamping plate extends into the positioning groove on the second clamping plate, thereby achieving the technical effect of positioning the circuit board to be tested. The circuit board to be tested, which is mounted between the first clamping plate and the second clamping plate, is supported by a spring sheet and mounted on the surface of the carrier plate, which can reduce the direct force on the solder joints of the component pins at the bottom of the circuit board to be tested during the detection process, resulting in poor contact, and provide good protection for the circuit board. In addition, since the spring sheet is elastic, the first clamping plate and the second clamping plate can be used to achieve the technical effect of clamping and positioning circuit boards of different thicknesses, thereby improving the usability of the adjustable clamping assembly.

[0018] Preferably, the spring sheet comprises an obliquely arranged guide portion, and the guide portion is arranged obliquely upward along the direction in which the circuit board to be tested extends.

[0019] By adopting the above technical solution, the guide part arranged obliquely on the spring sheet can make the positioning groove formed between the spring sheet and the positioning plate be arranged outward near the notch, which can improve the convenience for operators to clamp and position the side edges of the circuit board.

[0020] Preferably, the loading plate is provided with a mounting groove, a guide rod is fixedly installed in the mounting groove, and the bottom of the second clamping plate is fixedly connected with two connecting parts, and the two connecting parts are provided with through holes adapted to the guide rod;

[0021] A spring is coaxially sleeved on each of the two guide rods, one end of the spring is fixedly connected to the connecting portion, and one end of the spring away from the connecting portion is fixedly connected to the groove wall of the mounting groove.

[0022] By adopting the above technical solution, the spring in the installation groove forms a pulling force toward the first clamping plate on the connecting portion of the second clamping plate extending into the installation groove, so that the first clamping plate and the second clamping plate can be clamped on both sides of the circuit board to be tested, thereby improving the stability of the first clamping plate and the second clamping plate in clamping the circuit board to be tested. At the same time, the setting of the guide rod in the installation groove can limit the position of the spring and the second clamping plate, reduce the possibility of the connecting portion on the second clamping plate falling off from the installation groove, and reduce the irreversible deformation of the spring, thereby further improving the stability of the sliding connection structure of the second clamping plate.

[0023] Preferably, the sensing module comprises:

[0024] An infrared counter-radiation sensor, the transmitting end and the receiving end of which are respectively embedded and installed on the inner walls opposite to the slide groove, is used to sense the sliding action of the slider and output a low-level signal;

[0025] The single chip microcomputer is signal-connected to the signal output terminal of the infrared radiation sensor, and is used for receiving the low-level signal and outputting the sensing signal.

[0026] By adopting the above technical scheme, when the operator does not pull out the carrier board, the sliding part on the side wall of the carrier board blocks the transmitting end and the receiving end of the infrared counter-radiation sensor, the infrared rays emitted by the transmitting end cannot be received by the receiving end, and the infrared counter-radiation sensor sends a high-level signal; when the operator pulls the carrier board to make it slide out of the accommodating cavity, the sliding part slides out between the transmitting end and the receiving end, the infrared rays emitted by the transmitting end can be received by the receiving end, the infrared counter-radiation sensor outputs a low-level signal, and the single-chip microcomputer receives and recognizes the low-level signal, so as to determine that the operator is going to use the carrier board to clamp the circuit board to be tested, and control the fill light to emit light, thereby providing a clear field of vision for the operator to detect the circuit board to be tested.

[0027] Preferably, a gooseneck tube is fixedly connected to the platform, and the end of the gooseneck tube is fixedly connected to the fill light;

[0028] The signal input end of the fill light is signal-connected to the signal output end of the single-chip computer, and the fill light receives the sensing signal and emits light.

[0029] By adopting the above technical solution, the fill light is fixedly installed on the platform through the gooseneck tube, which makes it convenient for the operator to adjust the fill light angle of the fill light according to the required test points, further improving the convenience of the operator in using the fill light.

[0030] In summary, the present application provides an oscilloscope workbench with at least one of the following beneficial technical effects:

[0031] 1. The loading plate slidably connected to the table body and the first clamping plate and the second clamping plate on the loading plate are matched and used with each other. When the operator needs to use an oscilloscope to debug the circuit board, the operator can first pull out the loading plate in the accommodating cavity and clamp and fix the circuit board to be tested through the first clamping plate and the second clamping plate. The spring plates on the first clamping plate and the second clamping plate can improve the stability of the clamping of the circuit board to be tested, and can ensure that the first clamping plate and the second clamping plate are suitable for clamping circuit boards to be tested of different thicknesses, which effectively improves the usability of the workbench and the convenience of the operator using the workbench to assist the oscilloscope test;

[0032] 2. Through the coordination and use of the infrared beam sensor, the single-chip microcomputer and the fill light, the action of pulling out the carrier board can be automatically sensed, and the fill light can be automatically controlled to turn on when the operator pulls out the carrier board, providing the operator with a clear field of vision for debugging the circuit board to be tested, further improving the convenience of the operator using the oscilloscope to debug the circuit board.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] Example

[0040] The present application embodiment discloses a workbench for an oscilloscope. Figure 1 and Figure 4 It mainly includes a platform 1 placed beside the oscilloscope body 5, a receiving cavity 11 is opened at the bottom of the platform 1, a loading plate 2 is slidably connected in the receiving cavity 11, and an adjustable clamping component 3 for clamping a circuit board 6 to be tested is installed on the loading plate 2.

[0041] And: a sensing module, installed in the accommodating cavity 11, used to sense the movement of the carrier plate 2 sliding out of the accommodating cavity 11 and output a sensing signal; a fill light 12, fixedly installed on the platform 1, mounted above the carrier plate 2, with a signal input end connected to a signal output end of the sensing module, used to receive the sensing signal and emit light.

[0042] When using an oscilloscope to test the circuit board 6 to be tested, the operator can first pull out the carrier plate 2 in the accommodating cavity 11 on the platform 1, and clamp and fix the circuit board 6 to be tested through the adjustable clamping assembly 3 on the carrier plate 2, thereby achieving the technical effect of positioning and clamping the circuit board, thereby improving the convenience of the operator in testing the circuit board 6 to be tested.

[0043] At the same time, through the mutual coordination and use between the sensing module and the fill light 12, when the operator pulls out the carrier board 2, the sensing module outputs a sensing signal, and the fill light 12 receives the sensing signal and emits light, providing the operator with a clear field of vision for subsequent inspection of the circuit board, further improving the convenience of the operator in inspecting the circuit board 6 to be tested.

[0044] Reference Figure 1 and Figure 2 Slide grooves 13 are respectively provided on the two opposite inner side walls of the accommodating cavity 11, and sliding parts 21 are respectively fixedly connected to the two sides of the loading plate 2. The two sliding parts 21 are respectively embedded in the two slide grooves 13, and the two ends of the two slide grooves 13 are respectively integrally formed with anti-slip parts 14.

[0045] The sliding parts 21 on both sides of the carrier plate 2 extend into the slide groove 13. The operator can pull the carrier plate 2 to make the carrier plate 2 detach from the accommodating cavity 11 to expose the adjustable clamping assembly 3, so that the operator can perform subsequent circuit board testing operations; and due to the setting of the anti-detachment parts 14 at both ends of the slide groove 13, the occurrence of the sliding part 21 falling off from the slide groove 13 can be reduced, thereby improving the convenience of the operator to recover the carrier plate 2.

[0046] Four support rods 25 are fixedly connected to the bottom of the carrier plate 2. When the operator pulls out the carrier plate 2, the support rods 25 can support the carrier plate 2, thereby reducing the tilt of the carrier plate 2 and causing the circuit board 6 to be held by the carrier plate 2 to tilt, and further improving the stability of the clamping of the circuit board 6 to be tested.

[0047] Referring to the figure, the adjustable clamping assembly 3 includes a first clamping plate 31 and a second clamping plate 32. The first clamping plate 31 is fixedly mounted on the loading plate 2, and the second clamping plate 32 is adjustably mounted on the loading plate 2. Baffles 33 are fixedly connected to the first clamping plate 31 and the second clamping plate 32 respectively, and positioning plates 34 are fixedly connected to the opposite side walls of the two baffles 33 respectively.

[0048] The first clamping plate 31 and the second clamping plate 32 are respectively fixedly connected with spring pieces 35 opposite to the positioning plate 34 , and a positioning groove 36 for clamping the side edge of the circuit board is formed between any opposite spring pieces 35 and the positioning plate 34 .

[0049] During the process of installing the circuit board, the operator can first extend one side of the circuit board 6 to be tested into the positioning groove 36 on the first clamping plate 31, and then the operator can slide the second clamping plate 32 so that the side edge of the circuit board 6 to be tested away from the first clamping plate 31 extends into the positioning groove 36 on the second clamping plate 32, thereby achieving the technical effect of positioning the circuit board 6 to be tested.

[0050] The circuit board 6 to be tested, which is mounted between the first clamping plate 31 and the second clamping plate 32, is supported by the spring sheet 35 and mounted on the surface of the carrier plate 2, which can reduce the direct force on the solder joints of the component pins at the bottom of the circuit board 6 to be tested during the detection process, resulting in poor contact, and provide good protection for the circuit board. In addition, since the spring sheet 35 is elastic, the first clamping plate 31 and the second clamping plate 32 can be used to clamp and position circuit boards of different thicknesses, thereby improving the usability of the adjustable clamping assembly 3.

[0051] Reference Figure 3 The spring piece 35 includes a guide portion 351 that is arranged obliquely, and the guide portion 351 is arranged obliquely upward along the direction in which the circuit board 6 to be tested extends.

[0052] The guide portion 351 arranged obliquely on the spring piece 35 can make the positioning groove 36 formed between the spring piece 35 and the positioning plate 34 be arranged outward near the notch, which can improve the convenience for operators to clamp and position the sides of the circuit board.

[0053] Reference Figure 2 and Figure 3 A mounting groove 22 is provided on the loading plate 2, and a guide rod 23 is fixedly installed in the mounting groove 22. Two connecting parts 321 are fixedly connected to the bottom of the second clamping plate 32, and the two connecting parts 321 are provided with through holes 322 adapted to the guide rod 23; springs 24 are coaxially sleeved on the two guide rods 23, and one end of the spring 24 is fixedly connected to the connecting part 321, and the end of the spring 24 away from the connecting part 321 is fixedly connected to the groove wall of the mounting groove 22.

[0054] The spring 24 in the mounting groove 22 exerts a pulling force on the connecting portion 321 of the second clamping plate 32 extending into the mounting groove 22 toward the first clamping plate 31, so that the first clamping plate 31 and the second clamping plate 32 are clamped on both sides of the circuit board 6 to be tested, thereby improving the stability of the first clamping plate 31 and the second clamping plate 32 in clamping the circuit board 6 to be tested.

[0055] At the same time, the setting of the guide rod 23 in the installation groove 22 can limit the position of the spring 24 and the second clamping plate 32, thereby reducing the possibility that the connecting portion 321 on the second clamping plate 32 falls off from the installation groove 22 and the spring 24 undergoes irreversible deformation, thereby further improving the stability of the sliding connection structure of the second clamping plate 32.

[0056] Reference Figure 2 and Figure 4 The sensing module includes: an infrared counter-radiation sensor 4, whose transmitting end and receiving end are respectively embedded in the inner walls opposite to each other in the slide groove 13, for sensing the sliding action of the slider and outputting a low-level signal; a single-chip microcomputer, which is connected to the signal output end of the infrared counter-radiation sensor 4, for receiving the low-level signal and outputting a sensing signal.

[0057] When the operator does not pull out the carrier 2, the sliding part 21 on the side wall of the carrier 2 blocks the transmitting end and the receiving end of the infrared counter-radiation sensor 4, the infrared rays emitted by the transmitting end cannot be received by the receiving end, and the infrared counter-radiation sensor 4 sends a high-level signal; when the operator pulls the carrier 2 to slide it out of the accommodating cavity 11, the sliding part 21 slides out from between the transmitting end and the receiving end, the infrared rays emitted by the transmitting end can be received by the receiving end, and the infrared counter-radiation sensor 4 outputs a low-level signal. The single-chip microcomputer receives and recognizes the low-level signal, and can determine that the operator is going to use the carrier 2 to clamp the circuit board 6 to be tested, and control the fill light 12 to emit light, thereby providing a clear field of vision for the operator to detect the circuit board 6 to be tested.

[0058] It should be noted that in the embodiment of the present application, a battery module is installed inside the workbench, and the battery module can be used to power the single-chip microcomputer, the fill light 12 and the infrared radiation sensor 4.

[0059] In the embodiment of the present application, a gooseneck tube 15 is fixedly connected to the platform 1, and the end of the gooseneck tube 15 is fixedly connected to the fill light 12; the signal input end of the fill light 12 is connected to the signal output end of the microcontroller, and the fill light 12 receives the sensing signal and emits light.

[0060] The fill light 12 is fixedly mounted on the platform 1 via a gooseneck tube 15 , which allows an operator to adjust the fill light angle of the fill light 12 according to the points to be tested, further improving the convenience of the operator in using the fill light 12 .

[0061] The implementation principle of the oscilloscope workbench of the embodiment of the present application is as follows: through the sliding connection of the carrier plate 2 on the platform body 1 and the first clamping plate 31 and the second clamping plate 32 on the carrier plate 2, when the operator needs to use the oscilloscope to debug the circuit board, the operator can first pull out the carrier plate 2 in the accommodating cavity 11 and clamp and fix the circuit board 6 to be tested through the first clamping plate 31 and the second clamping plate 32. The spring pieces 35 on the first clamping plate 31 and the second clamping plate 32 can improve the stability of clamping the circuit board 6 to be tested, and can ensure the stability of the first clamping plate 31 and the second clamping plate 32. The clamping plate 31 and the second clamping plate 32 are suitable for clamping circuit boards 6 to be tested of different thicknesses, which effectively improves the usability of the workbench and the convenience of the operator using the workbench to assist the oscilloscope test; through the mutual coordination and use of the infrared counter-radiation sensor 4, the single-chip microcomputer and the fill light 12, it can automatically sense the action of pulling out the carrier board 2, and automatically control the fill light 12 to turn on when the operator pulls out the carrier board 2, providing the operator with a clear field of vision for debugging the circuit board 6 to be tested, further improving the convenience of the operator using the oscilloscope to debug the circuit board.
