Description

Technical Field

[0001] The present invention relates to the technical field of circuit detection, in particular to a circuit detection device of electrical automation technology. Background Art

[0002] Electrical automation is a comprehensive technology that integrates knowledge from the fields of electrical engineering, automatic control, and computer science. Through intelligent control and automated management of electrical equipment and systems, it achieves precise control, status monitoring, and optimized operation of production processes or mechanical equipment.

[0003] With the deepening of intelligent manufacturing, the application of electrical automation systems in industrial production, energy and electricity, and transportation has become increasingly extensive and complex. The scale of electrical equipment and circuit systems has continued to expand, and the structure has become increasingly sophisticated. Traditional manual detection methods can no longer meet the needs in terms of efficiency, accuracy, and real-time performance. At this time, a circuit detection device based on electrical automation technology is needed.

[0004] The circuit detection devices of electrical automation technology currently on the market are mainly used to detect PCB boards inside electrical automation equipment. The circuit is detected by using a probe to contact the PCB board. However, during use, due to the large number of test points, the probe needs to be detected point by point, resulting in a long test time. The existing technology integrates the probe on the needle bed to achieve single full-point detection, thereby greatly shortening the detection time. However, after multiple tests, the friction between the probe and the pad will cause wear, resulting in a decrease in detection accuracy. Since the value of the needle bed is high, frequent replacement will lead to increased costs. To solve the above problems, the existing technology improves the wear resistance and conductivity of the probe by gold plating or rhodium-iridium plating on the probe head. However, when in use, when the device detects a used circuit board, dust accumulates on the circuit board after use, resulting in poor contact between the probe and the contact, reducing the accuracy of the device and failing to meet the needs of users.

The inner sides of the two curved grooves 44 are slidably connected with plug-in columns 45. The support plate 43 can push the plug-in columns 45 to move through the curved grooves 44. The tops of the two plug-in columns 45 are fixedly connected to a connecting plate 46. The two connecting plates 46 are fixedly connected to a card block 47 at one end away from each other.

The inner left side of the hollow block 410 is fixedly connected to a limiting plate 494. The outer side of the limiting plate 494 is slidably connected to the second rack 493, and the movement of the second rack 493 is limited by the limiting plate 494. Specifically, when different circuit boards need to be tested, different needle beds 48 need to be replaced, and the second threaded rod 492 is rotated. The second threaded rod 492 will drive the second rack 493 to move. Since the second gear 491 is engaged with the second rack 493, the movement of the second rack 493 will drive the second gear 491 to rotate, and drive the support plate 43 to rotate through the transmission rod 42. The support plate 43 can push the plug-in column 45 to move through the curved groove 44 thereon. The movement of the plug-in column 45 is transmitted to the block 47 through the connection of the connecting plate 46, so that the block 47 can move, so that the block 47 is out of the engaged state with the needle bed 48, and the needle bed 48 can be easily disassembled, reducing the workload of the staff.

[0025] Reference Figure 1 and Figure 3The lifting assembly 28 includes an outer frame 281, and the two outer frames 281 are respectively slidably connected to the front and rear sides of the bracket 21.

The top of the slider 25 is slidably connected to the slide groove 210, and the movement of the slider 25 can be limited by the slide groove 210. Specifically, by rotating the first threaded rod 282, the connecting block 283 can be driven to move, and further the bracket 21 can be driven to move, so that the height of the bracket 21 can be adjusted according to the thickness of the circuit board, and the slider 25 can be limited by the slide groove 210, so that when the reciprocating screw rod 24 rotates, the slider 25 can move accordingly.

[0026] Reference Figure 1 and Figure 4 A U-shaped frame 6 is fixedly connected to the middle of the top of the workbench 1. The left and right sides of the inner side of the U-shaped frame 6 are rotatably connected to the driving rollers 7. The two driving rollers 7 are connected by a conveyor belt 8. A third motor 9 is fixedly connected to the left side of the rear wall of the U-shaped frame 6. The front end of the third motor 9 passes through the U-shaped frame 6 and is fixedly connected to the left driving roller 7. The third motor 9 can drive the left driving roller 7 to rotate; Specifically, the third motor 9 drives the left driving roller 7 to rotate, thereby driving the conveyor belt 8 to move, thereby conveying the circuit board.

[0027] Working principle: When using this device, the circuit board can be transported by the conveyor belt 8. When the circuit board moves to the inside of the bracket 21, the first motor 23 drives the reciprocating screw 24 to rotate. The reciprocating screw 24 is driven left and right by the pulley 271 and the transmission belt 272, which can drive the cleaning roller 22 to rotate, thereby cleaning the dust on the circuit board. When the reciprocating screw 24 rotates, it drives the slider 25 on its outside to reciprocate back and forth, thereby driving the dust collection head 26 to move, and all the dust brushed by the cleaning roller 22 is sucked out, so that there will be no residual dust on the circuit board, which will cause poor contact between the probe and the electric shock. When the device is used to inspect a circuit board, the second motor 31 is started and drives the bidirectional threaded rod 32 to rotate. The rotation of the bidirectional threaded rod 32 drives the two outer support plates 33 to close toward the middle. The support plates 33 then drive the supporting plate 37 to move toward the middle through the rotating rod 34, scooping up the circuit board. Since the first gear 35 is engaged with the first rack 36, the rotating rod 34 drives the first gear 35 to move and rotates accordingly, thereby further driving the supporting plate 37 to rotate, positioning the circuit board at the inspection position, so that the contacts on the circuit board can match the inspection probes. Finally, when different circuit boards need to be tested, different needle beds 48 need to be replaced. At this time, the second threaded rod 492 is rotated. The rotation of the second threaded rod 492 will drive the second rack 493 to move. Since the second gear 491 is engaged with the second rack 493, when the second rack 493 moves, the second gear 491 will rotate accordingly, and drive the support plate 43 to rotate through the transmission rod 42. The support plate 43 can push the plug-in column 45 to move through the curved groove 44 thereon. The plug-in column 45 can push the block 47 to move through the connecting plate 46, so that the block 47 is disengaged from the needle bed 48, and the needle bed 48 can be easily disassembled.
