Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board detection device. Background Art

[0002] After the production of the circuit board is completed, it is usually necessary to use a circuit board detection device to detect the circuit board. During the detection, the circuit board to be tested needs to be fixed in the test position by a clamping assembly, and then the probe is moved downward to contact the circuit board, so as to detect the circuit board to be tested. The fixing structure of the existing circuit board detection device usually includes two clamps arranged opposite to each other. The circuit board is clamped and fixed by moving the two clamps relatively close to each other. Although this structure can fix the circuit board to be tested from two opposite sides, the circuit board to be tested may still be displaced in the direction perpendicular to the connection line of the two clamps. In addition, if the test position is uneven, when the probe moves downward to contact the circuit board to be tested for detection, it is easy to cause the circuit board to be tested to tilt up and down, which is easy to affect the test results of the circuit board to be tested.

[0032] Reference Figures 1 to 3One embodiment of the utility model provides a circuit board detection device, including a workbench 100, a detection component 200, a first clamping component and a second clamping component. The workbench 100 has a test position 110 for placing a circuit board 400 to be tested. The detection component 200 is arranged on the workbench 100 and is located above the test position 110. The first clamping component includes two side clamping plates 300, which are movably mounted on the workbench 100 and are relatively arranged at the front and rear sides of the test position 110, and the two side clamping plates 300 can move closer or farther away from each other. The second clamping component includes an upper clamping plate 310 and a lower clamping plate 320 arranged on the workbench 100, and the upper clamping plate 310 and the lower clamping plate 320 can be correspondingly located above and below the test position 110, and the upper clamping plate 310 and the lower clamping plate 320 can move closer or farther from each other in the up and down directions.

[0033] By adopting the above structure, during testing, the circuit board 400 to be tested is placed in the test position 110, and the two side clamping plates 300 of the first clamping assembly can be relatively moved close to each other in the front-to-back direction, so that the circuit board can be clamped from the front and back sides of the circuit board 400 to be tested, and the upper clamping plate 310 and the lower clamping plate 320 of the second clamping assembly can be correspondingly located above and below the test position 110, and the upper clamping plate 310 and the lower clamping plate 320 can be relatively moved close to each other in the up-down direction, so that the circuit board 400 to be tested can be clamped and fixed from the upper and lower sides of the circuit board, thereby improving the clamping force of the circuit board 400 to be tested, and can clamp and fix the circuit board 400 to be tested more stably. In addition, the structure can also reduce the risk of displacement of the circuit board 400 to be tested in the left-right direction of the test position 110, and can also reduce the risk of the circuit board 400 to be tested tilting up and down during detection, thereby improving the detection accuracy of the circuit board.

[0034] Reference Figures 1 to 3 In some embodiments, the number of the second clamping components is two groups, and the two groups of second clamping components are correspondingly arranged on two opposite sides of the test position 110.

[0035] By adopting the above structure, the two groups of second clamping components can cooperate to clamp the circuit board 400 to be tested from the opposite sides of the circuit board 400, thereby not only improving the clamping force of the circuit board 400 to be tested, making the fixation of the circuit board 400 to be tested more stable, but also making the force on the circuit board 400 to be tested more balanced, further reducing the risk of the circuit board 400 to be tested tilting up and down.

[0036] Reference Figures 1 to 3In some embodiments, the upper clamping plate 310 has an upper clamping portion 311 and an upper connecting portion 312, and the upper clamping portion 311 is located on a side of the upper connecting portion 312 close to the test position 110; the lower clamping plate 320 has a lower clamping portion 321 and a lower connecting portion 322, and the lower clamping portion 321 is located on a side of the lower connecting portion 322 close to the test position 110. The two sets of second clamping assemblies are correspondingly arranged at the front and rear sides of the test position 110. In the first clamping assembly and the second clamping assembly located at the same side of the test position 110, the upper connecting portion 312 is fixedly connected to the side clamping plate 300, and the lower clamping plate 320 is slidably connected to the side clamping plate 300 and can move relative to the side clamping plate 300 in the up and down directions.

[0037] By adopting the above structure, the upper clamping plate 310 and the lower clamping plate 320 can follow the side clamping plate 300 to move closer to or away from the circuit board 400 to be tested, and the side clamping plate 300 can follow the upper clamping plate 310 to move closer to or away from the lower clamping plate 320 in the up and down direction. During the test, the circuit board 400 to be tested is placed in the test position 110, and the two side clamping plates 300 are relatively moved close to clamp the circuit board 400 to be tested. In this process, the upper clamping plate 310 and the lower clamping plate 320 will also follow the corresponding side clamping plate 300 to move close to the circuit board 400 to be tested, so that the upper clamping plate 310 and the lower clamping plate 320 are correspondingly located at the upper and lower sides of the circuit board 400 to be tested, and then the upper clamping plate 310 and the lower clamping plate 320 are relatively moved close to each other, so that the circuit board 400 to be tested can be clamped and fixed from the upper and lower sides. It can be seen that the above structure can connect the upper clamping plate 310, the lower clamping plate 320 and the side clamping plate 300 together to form a whole, thereby making the structure of the circuit board detection device more compact and making it more convenient to clamp and fix the circuit board 400 to be tested.

[0038] It can be understood that the upper connecting portion 312 is fixedly connected to the side clamping plate 300, and the lower clamping plate 320 is slidably connected to the side clamping plate 300 and can move in the up and down direction relative to the side clamping plate 300. Figures 1 to 3 As an exemplary illustration, in addition to this, the lower connecting portion 322 can also be fixedly connected to the side clamping plate 300, and the upper clamping plate 310 can be slidably connected to the side clamping plate 300 and can move relative to the side clamping plate 300 in the up-down direction. At this time, the upper clamping plate 310 and the lower clamping plate 320 can move together with the side clamping plate 300 to approach or move away from the circuit board 400 to be tested, and the side clamping plate 300 can move together with the lower clamping plate 320 to approach or move away from the lower clamping plate 320 in the up-down direction. It can be seen that this structure can also connect the upper clamping plate 310, the lower clamping plate 320 and the side clamping plate 300 together to form a whole, so that the structure of the circuit board detection device is more compact, and the clamping and fixing of the circuit board 400 to be tested can be made more convenient.

[0039] Reference Figure 1and Figure 2 In some embodiments, the circuit board detection device also includes a first driving mechanism 330 installed on the workbench 100. In the first clamping assembly and the second clamping assembly located on the same side of the workbench 100, the lower clamping plate 320 is transmission-connected to the output end of the first driving mechanism 330. The first driving mechanism 330 can drive the upper clamping plate 310, the lower clamping plate 320, and the side clamping plate 300 to move in the front-to-back direction close to the test position 110, and make the circuit board 400 to be tested be located between the upper clamping portion 311 and the lower clamping portion 321.

[0040] In the above structure, the first driving mechanism 330 can drive the lower clamping plate 320 to move in the front-to-back direction close to or away from the test position 110. Since one of the upper clamping plate 310 and the lower clamping plate 320 is fixedly connected to the side clamping plate 300, and the other is slidably connected to the side clamping plate 300 and can move in the up-down direction relative to the side clamping plate 300, the lower clamping plate 320 can drive the upper clamping plate 310 and the side clamping plate 300 to move synchronously in the front-to-back direction, that is, the first driving mechanism 330 can drive the upper clamping plate 310 and the side clamping plate 300 to move synchronously in the front-to-back direction. 10. The lower clamping plate 320 and the side clamping plate 300 are moved in the front-to-back direction to approach the test position 110. When the side clamping plate 300 is moved to abut against the circuit board 400 to be tested, the upper clamping plate 310 and the lower clamping plate 320 are correspondingly located at the upper and lower sides of the circuit board 400 to be tested, so that the circuit board 400 to be tested is located between the upper clamping portion 311 and the lower clamping portion 321. At this time, the circuit board 400 to be tested can be clamped and fixed from the upper and lower sides by relatively moving the upper clamping plate 310 and the lower clamping plate 320 closer. It can be seen that the setting of the first driving mechanism 330 can push the side clamping plate 300 to continuously press against the side surface of the circuit board 400 to be tested, thereby further improving the clamping force of the side clamping plate 300 on the circuit board 400 to be tested. At the same time, since the first driving mechanism 330 can drive the upper clamping plate 310, the lower clamping plate 320, and the side clamping plate 300 to move along the front-to-back direction close to the test position 110, and make the circuit board 400 to be tested be located between the upper clamping portion 311 and the lower clamping portion 321, the clamping and fixing of the circuit board 400 to be tested is more convenient and quick.

[0041] It is understandable that in some embodiments, the output end of the first driving mechanism 330 is provided with a screw arranged in the front-to-back direction, and the lower clamping plate 320 is provided with a threaded hole adapted to the screw, so that when the first driving mechanism 330 drives the screw to rotate, the lower clamping plate 320 can be driven to move in the front-to-back direction. Of course, in addition to this, the first driving mechanism 330 can also directly select a linear driving mechanism such as a motor push rod, a cylinder or a hydraulic cylinder, and the utility model does not make specific limitations on this.

[0042] It can be understood that since one of the upper clamping plate 310 and the lower clamping plate 320 is fixedly connected to the side clamping plate 300, and the other is slidably connected to the side clamping plate 300 and can move in the up and down directions relative to the side clamping plate 300, in order to be able to drive the upper clamping plate 310, the lower clamping plate 320, and the side clamping plate 300 to move synchronously in the front and rear directions, in addition to connecting the lower clamping plate 320 to the output end of the first driving mechanism 330, the upper clamping plate 310 or the side clamping plate 300 can also be connected to the output end of the first driving mechanism 330, or two of the upper clamping plate 310, the lower clamping plate 320, and the side clamping plate 300 can also be connected to the output end of the first driving mechanism 330, and the upper clamping plate 310, the lower clamping plate 320, and the side clamping plate 300 can also be connected to the output end of the first driving mechanism 330, and the utility model does not make specific limitations on this.

[0043] Reference Figure 1 and Figure 2 In some embodiments, the upper connecting portion 312 is fixedly connected to the side clamp plate 300, the lower connecting portion 322 is slidably connected to the side clamp plate 300, the workbench 100 is provided with a second driving mechanism, the upper clamp plate 310 is transmission-connected to the second driving mechanism, and the second driving mechanism can drive the upper clamp plate 310 and the side clamp plate 300 to move in the up and down directions toward or away from the lower clamp plate 320.

[0044] By adopting the above structure, the second driving mechanism can drive the upper clamping plate 310 to move in the up and down direction close to the lower clamping plate 320, so that the upper clamping plate 310 can cooperate with the lower clamping plate 320 to clamp the circuit board 400 to be tested. The structure is simple and easy to operate. The second driving mechanism can also push the upper clamping plate 310 to continuously abut against the upper surface of the circuit board 400 to be tested, thereby further improving the clamping and fixing effect of the upper clamping plate 310 and the lower clamping plate 320 on the circuit board 400 to be tested.

[0045] It can be understood that since the side clamp 300 is fixedly connected to the upper clamp 310, in order to be able to drive the upper clamp 310 to move in the up and down direction closer to or away from the lower clamp 320, in addition to the upper clamp 310 being transmission connected to the second drive mechanism, the side clamp 300 can also be transmission connected to the second drive mechanism, or the upper clamp 310 and the side clamp 300 can be transmission connected to the second drive mechanism at the same time, and the present invention does not make specific limitations on this.

[0046] It is understandable that the second driving mechanism may specifically be a linear driving mechanism such as an electric push rod, a cylinder or a hydraulic cylinder, and the present invention does not make any specific limitation on this.

[0047] Reference Figure 1 and Figure 2In some embodiments, a slide groove is provided on the lower end surface of the side clamping plate 300, the lower connecting portion 322 is connected to the lower clamping portion 321 and extends upward relative to the lower clamping portion 321, and the lower connecting portion 322 is movably inserted in the slide groove.

[0048] In the above structure, by setting a sliding groove on the lower end surface of the side clamping plate 300, and extending the lower connecting portion 322 upward relative to the lower clamping portion 321, the lower clamping plate 320 can be movably plugged into the side clamping plate 300, thereby realizing a movable connection between the lower clamping plate 320 and the side clamping plate 300, so that the side clamping plate 300 can drive the upper clamping plate 310 to move closer to or away from the lower clamping plate 320 in the up and down directions. This connection method has a simple structure, which makes the structure of the circuit board detection device simpler, facilitates processing and production, and is also convenient for clamping and fixing the circuit board 400 to be tested.

[0049] Reference Figures 1 to 3 In some embodiments, the workbench 100 is provided with two supporting portions 120 for supporting the circuit board 400 to be tested. The supporting portions 120 protrude upward relative to the workbench 100 . The two supporting portions 120 are correspondingly arranged on opposite sides of the test position 110 , and the lower clamping plate 320 can extend between the two supporting portions 120 .

[0050] By adopting the above structure, the circuit board 400 to be tested can be placed on the two supporting parts 120 during testing. When clamping and fixing, the circuit board 400 to be tested can be fixed from the front and back sides by the two side clamping plates 300, and then the lower clamping plate 320 is extended between the two supporting parts 120, so that the lower clamping plate 320 is located below the circuit board 400 to be tested, and the upper clamping plate 310 is located above the circuit board 400 to be tested. At this time, the circuit board 400 to be tested can be fixed from the upper and lower sides by the upper clamping plate 310 and the lower clamping plate 320.

[0051] It can be understood that in addition to supporting the circuit board 400 to be tested by providing two supporting parts 120, in some embodiments, a placement panel can also be directly provided on the workbench 100, and the test position 110 is located on the upper surface of the placement panel, and a receiving groove for accommodating the lower clamping plate 320 is provided on the placement panel, so that the lower clamping plate 320 can be extended to the bottom of the test position 110, so that it can be located below the circuit board 400 to be tested, and then the circuit board 400 to be tested can be fixed from the upper and lower sides by the upper clamping plate 310 and the lower clamping plate 320.

[0052] Reference Figures 1 to 5In some embodiments, the detection component 200 includes a pressing plate 210 movably installed above the test position 110, a probe 220 is installed on the lower surface of the pressing plate 210, and an elastic component 230 is arranged between the pressing plate 210 and the workbench 100. The elastic component 230 can drive the pressing plate 210 to drive the probe 220 to move upward.

[0053] By adopting the above structure, after the circuit board 400 to be tested is clamped and fixed, the pressing plate 210 can be pressed downward to make the elastic component 230 contract, and the probe 220 moves downward following the pressing plate 210 and contacts the circuit board 400 to be tested, so that the circuit board 400 to be tested can be tested. After the test, the pressing plate 210 is released, and the elastic component 230 is reset due to its own elastic force and pushes the pressing plate 210 to move upward and reset. The probe 220 can move upward following the pressing plate 210 to leave the circuit board 400 to be tested. The structure is simple and easy to operate.

[0054] Reference Figures 1 to 5 In some embodiments, the detection component 200 includes a mounting base 240 installed on the workbench 100, the mounting base 240 is provided with a detection groove 241 located above the test position 110, the side wall of the detection groove 241 is provided with a mounting groove 242 for installing the elastic component 230, the elastic component 230 is connected to or abuts the side wall of the mounting groove 242, the pressure plate 210 is movably installed in the detection groove 241, and the edge of the pressure plate 210 is provided with an abutment portion 211 extending outward to the mounting groove 242, and the abutment portion 211 is connected to or abuts the upper end of the elastic component 230.

[0055] By adopting the above structure, a detection groove 241 and a mounting groove 242 are opened on the mounting seat 240, the pressure plate 210 is movably installed in the detection groove 241, and the elastic component 230 is installed in the mounting groove 242 and is connected or abutted with the abutment portion 211 of the pressure plate 210, thereby making the structure of the detection component 200 more compact and facilitating the installation, disassembly and maintenance of the pressure plate 210, the elastic component 230 and other components in the detection component 200.

[0056] Reference Figures 1 to 5 In some embodiments, the number of elastic components 230 is two sides, the mounting seat 240 is correspondingly provided with two mounting grooves 242, and the pressing plate 210 is correspondingly provided with two abutting portions 211, thereby making the structure of the detection component 200 more compact, and also making the lifting process of the pressing plate 210 more balanced and stable, which is conducive to improving the detection accuracy of the circuit board 400 to be tested. Specifically, the two sets of elastic components 230 can be correspondingly arranged on the opposite sides of the pressing plate 210, thereby further improving the lifting stability of the pressing plate 210.

[0057] Reference Figure 4 and Figure 5In some embodiments, the elastic component 230 includes an elastic column 232 and a compression spring 231 , and the compression spring 231 is sleeved on the outer circumference of the elastic column 232 .
