[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention places the circuit board to be tested on the surface of the test bench, controls the gas generated by the air pump to be transported to the inside of the sleeve through the connecting pipe A, so that the gas pressure in the sleeve increases, and the gas pushes the sliding rod to move, driving the clamping plate to move synchronously to both sides of the circuit board, so that the clamping plate pushes the clamping block to clamp and fix both sides of the circuit board, thereby achieving the effect of clamping and fixing the circuit board placed on the test bench, avoiding the circuit board placed on the test bench being subjected to external force collision during the operation of the tester, resulting in the displacement of the circuit board, thereby causing errors in the test of the tester, and improving the accuracy of the device detection.

[0022] 2. The present invention lifts the measuring rod and moves it so that the contact head at the bottom end of the measuring rod contacts the top of the circuit board. During the movement of the measuring rod, the measuring rod synchronously drives the slider to move along the inner wall of the guide rail, so that the slider drives the L-shaped rod to move. The L-shaped rod further drives the rack A at its top to move, so that the rack A drives the control rod to rotate, so that the opening of the throttle valve can be adjusted by rotating the control rod, and the air intake speed is adjusted according to the thickness of the circuit board, so that the air pressure is slowly and evenly applied to the circuit board, reducing the bending and cracking caused by instantaneous excessive air pressure due to air pressure shock, protecting the integrity of the circuit board, and eliminating the need for manual intervention, greatly saving detection time and labor costs, and improving test efficiency and reliability.

[0023] 3. The present invention drives the mounting base downward through the cylinder, so that the probe at the bottom end of the mounting base moves downward synchronously until the needle tip of the probe contacts the solder joint on the surface of the circuit board, controls the solenoid valve on the surface of the connecting pipe A to open, and the gas enters the air cavity inside the mounting base through the connecting pipe A, so that the gas pushes the piston to move downward, and the movement of the piston drives the probe to apply pressure to the solder joint. Normally welded solder joints can withstand a certain pressure, but when the cold solder joints are under pressure, the probe will have abnormal displacement. If the probe at the cold solder joint is pressed down deeper than the probe at the normal solder joint by a certain threshold, the displacement sensor on the top of the piston will convert the measured value into an electrical signal and transmit it to the external display. The staff can intuitively observe the specific position of the cold solder joint through the external display, so that they can quickly locate welding defects, accurately identify cold solder joints, and improve detection efficiency and accuracy.

[0024] 4. The present invention drives the mounting seat downward by the cylinder, and the mounting seat drives the connecting rod to move downward synchronously, and the connecting rod drives the movable plug to slide down along the inside of the exhaust pipe, and the movable plug draws the external gas into the interior of the exhaust pipe through the one-way suction valve. When the pressure detection is completed, the cylinder drives the mounting seat upward, so that the connecting rod drives the movable plug upward, and the movable plug compresses the gas inside the exhaust pipe into the interior of the sleeve through the connecting pipe B. The gas pushes the push rod to move, and the push rod drives the rack B to move and drive the gear B to rotate. The gear B drives the rotating rod to rotate, so that the rotating rod drives the cam to rotate synchronously, so that the test bench is vibrated by the rotation of the cam. The stress generated by the vibration will cause the cracks in the solder joints to expand, and the solder joints will shake abnormally, thereby effectively detecting such solder joints with cracks inside, and avoiding damage to the circuit board due to solder joint failure during use.

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The present invention provides a high-efficiency online ICT intelligent testing device, comprising a machine platform 1, a tester 2 fixedly mounted on the top of the machine platform 1, a cylinder 3 fixedly mounted on the top of the tester 2, a mounting base 4 fixedly mounted on the output end of the cylinder 3, limit rods 5 symmetrically arranged in pairs installed inside the tester 2, a test table 7 slidingly mounted on the outer wall of the limit rods 5, an air pump 8 fixedly mounted on the bottom end of the test table 7, a clamping mechanism 9 for fixing a circuit board provided on the top of the test table 7, a pressure detection mechanism 10 for detecting the circuit board provided on the bottom end of the mounting base 4, an adjustment mechanism 11 for adjusting the gas flow rate provided on one side of the top of the test table 7, and a vibration detection mechanism 12 for vibrating the circuit board provided on the bottom of the test table 7;

[0038] See Figures 1 to 3 As shown, the clamping mechanism 9 includes a clamping plate 901 that slides on the surface of the test table 7. A sleeve 905 is fixedly installed at the bottom of the test table 7. A sliding rod 906 slides inside the sleeve 905. One end of the sliding rod 906 extends through the interior of the sleeve 905 and is fixedly connected to the clamping plate 901. The air pump 8 is connected to the sleeve 905 through a connecting pipe A907.

[0039] It should be noted that, the circuit board to be tested is placed on the surface of the test bench 7, and the air pump 8 is started. The gas generated by the air pump 8 is transported to the inside of the sleeve 905 through the connecting pipe A907, so that the gas pressure in the sleeve 905 increases, and the increased gas pushes the slide bar 906 to move outward. The movement of the slide bar 906 drives the clamp 901 to move synchronously to both sides of the circuit board, so that the clamp 901 pushes the clamp block 904 to clamp both sides of the circuit board, thereby achieving the effect of clamping and fixing the circuit board placed on the test bench 7, avoiding the situation where the circuit board placed on the test bench 7 is subjected to external force collision during the operation of the tester 2, resulting in displacement of the circuit board, thereby causing errors in the test of the tester 2, and improving the accuracy of the device detection.

[0040] See Figures 4 to 9 As shown, the pressure detection mechanism 10 includes a circular tube 1001 mounted at the bottom end of the mounting base 4, a piston 1002 slidingly arranged inside the circular tube 1001, a probe 1003 fixedly connected to the bottom end of the piston 1002, an air cavity 1005 communicating with the circular tube 1001 is opened inside the mounting base 4, the air pump 8 and the air cavity 1005 are connected via an air pipe 1006, a throttle valve 1007 is provided on the outer wall of the air pipe 1006, and a solenoid valve 1008 is provided on the outer wall of the connecting pipe A907 and the air pipe 1006;

[0041] It should be noted that after the circuit board is fixed, the cylinder 3 is started, and the cylinder 3 drives the mounting base 4 to move downward, thereby causing the probe 1003 at the bottom end of the mounting base 4 to move downward synchronously until the needle of the probe 1003 contacts the solder joint on the surface of the circuit board, and the solenoid valve 1008 on the surface of the control connecting pipe A907 is opened, and the gas enters the air cavity 1005 inside the mounting base 4 through the connecting pipe A907. Subsequently, the gas enters the circular tube 1001 through the air cavity 1005, so that the gas pushes the piston 1002 to move downward, and the movement of the piston 1002 drives the probe 100 3. Apply pressure to the solder joints. Normal solder joints can withstand a certain amount of pressure, but when pressure is applied to cold solder joints, the probe 1003 will be abnormally displaced. If the probe 1003 at the cold solder joint is pressed down deeper than a certain threshold value than the probe 1003 at the normal solder joint, the displacement sensor on the top of the piston 1002 will convert the measured value into an electrical signal and transmit it to the external display. The staff can visually observe the specific position of the cold solder joint through the external display, so that they can quickly locate welding defects, accurately identify cold solder joints, and improve detection efficiency and accuracy.

[0042] See Figures 4 to 7 As shown, the adjustment mechanism 11 includes a guide rail 1101 fixedly connected to one side of the top of the test bench 7, a slider 1102 slides inside the guide rail 1101, a measuring rod 1104 is fixedly connected to the side of the slider 1102 away from the inner wall of the guide rail 1101, an L-shaped rod 1106 is fixedly connected to one side of the slider 1102, a rack A1107 is fixedly connected to the top of the L-shaped rod 1106, a control rod 1108 is installed on the outer wall of the throttle valve 1007, and a gear ring 1109 is sleeved on the outer wall of one end of the control rod 1108 and meshed with the rack A1107;

[0043] It should be noted that, according to the different thickness models of the circuit boards, the circuit board to be tested is placed on the test bench 7, and the staff can lift the measuring rod 1104 and move it so that the contact head 1105 at the bottom end of the measuring rod 1104 contacts the top of the circuit board. During the movement of the measuring rod 1104, the measuring rod 1104 synchronously drives the slider 1102 to move along the inner wall of the guide rail 1101, so that the slider 1102 drives the L-shaped rod 1106 to move, and further the L-shaped rod 1106 drives the rack A1107 at its top to move. The meshing relationship between the rack A1107 and the ring gear 1109 enables the rack A1107 to drive the control rod 1108 to rotate, so that the opening of the throttle valve 1007 can be adjusted by rotating the control rod 1108, and the air intake speed is adjusted according to the thickness of the circuit board, so that the air pressure is slowly and evenly applied to the circuit board, reducing the bending and cracking caused by instantaneous excessive air pressure due to air pressure shock, protecting the integrity of the circuit board, and eliminating the need for manual intervention, greatly saving detection time and labor costs, and improving test efficiency and reliability.

[0044] In addition, for different types of circuit boards, the air pressure can be appropriately increased for testing, and the air pressure can be adjusted according to actual conditions to avoid damage to solder joints due to excessive air pressure. Generally, the air pressure can be controlled within the range of 0.1-0.5MPa.

[0045] See Figure 8 As shown, the vibration detection mechanism 12 includes fixed bases 1201 symmetrically mounted inside the tester 2, a rotating rod 1202 rotates between the two sets of fixed bases 1201, one end of the rotating rod 1202 is mounted with a gear B1203, the outer wall of the rotating rod 1202 is provided with multiple sets of cams 1204, and one side of the gear B1203 is provided with a driving mechanism;

[0046] It should be noted that when the cylinder 3 drives the mounting seat 4 to move downward, the mounting seat 4 drives the connecting rod 1206 on one side to move downward synchronously, and the connecting rod 1206 drives the movable plug 1207 to slide down along the inside of the exhaust pipe 1205, so that the movable plug 1207 sucks the external gas into the interior of the exhaust pipe 1205 through the one-way suction valve. When the pressure detection is completed, the cylinder 3 drives the mounting seat 4 to move upward, so that the mounting seat 4 synchronously drives the connecting rod 1206 to move upward, so that the connecting rod 1206 drives the movable plug 1207 to move upward, and the movable plug 1207 compresses the gas inside the exhaust pipe 1205 into the interior of the sleeve 1208 through the connecting pipe B1209, so that the inside of the sleeve 1208 The gas pressure in the upper part increases, and the gas pushes the push rod 1210 to move, and the push rod 1210 further pushes the rack B1211 to move. Due to the meshing relationship between the rack B1211 and the gear B1203, the rack B1211 drives the gear B1203 to rotate, and the gear B1203 drives the rotating rod 1202 to rotate synchronously, so that the rotating rod 1202 drives the cam 1204 to rotate synchronously, so that the rotation of the cam 1204 is used to vibrate the test bench 7. The stress generated by the vibration will cause the cracks in the solder joints to expand, and the solder joints will shake abnormally, so that such solder joints with cracks inside can be effectively detected, thereby avoiding damage to the circuit board due to solder joint failure during use.

[0047] See Figure 2 As shown, two groups of symmetrically arranged guide columns 6 are installed inside the tester 2, and the mounting seat 4 slides on the outer wall of the guide columns 6. The guide columns 6 effectively prevent the mounting seat 4 from deflecting or shaking during movement, thereby improving the operating accuracy and stability of the device.

[0048] See Figure 3 As shown, multiple sets of springs A903 are installed on one side of the clamping plate 901, and a clamping block 904 is fixedly connected to one side of the multiple sets of springs A903. The presence of the springs A903 enables the clamping block 904 to automatically adapt to its shape and size when contacting the circuit board, avoiding damage or deformation of the circuit board due to excessive clamping force, thereby effectively protecting the integrity of the circuit board.

[0049] See Figure 3 As shown, two groups of symmetrically arranged slide grooves 902 are opened on the surface of the test bench 7, and the splint 901 slides on the inner wall of the slide groove 902, so that the splint 901 remains stable when moving horizontally, avoiding displacement of the splint 901 due to external force or vibration.

[0050] See Figure 3 As shown, a spring B908 is provided inside the sleeve 905, and the spring B908 is sleeved on the outer wall of the slide bar 906. When the clamp 901 releases the circuit board, the restoring force of the spring B908 will push the slide bar 906 back to the initial position, thereby simplifying the operation process and improving the test efficiency.

[0051] See Figures 4 and 5 As shown, a spring C1004 is provided inside the circular tube 1001. The spring C1004 is fixedly installed between the inner wall of the circular tube 1001 and the top of the piston 1002. The spring C1004 provides an elastic buffer for the movement of the piston 1002, and can absorb part of the impact force when the probe 1003 contacts the solder joint of the circuit board, thereby preventing damage to the solder joint or the probe 1003 due to excessive instantaneous pressure.

[0052] See Figure 7 As shown, a contact head 1105 is fixedly installed at the bottom end of the measuring rod 1104. The contact head 1105 is made of rubber material. When the measuring rod 1104 contacts the circuit board, the rubber contact head 1105 can avoid scratches, indentations or other mechanical damages to the surface of the circuit board, thereby protecting the integrity of the circuit board.

[0053] See Figure 7 As shown, a spring D1103 is provided inside the guide rail 1101, one end of the spring D1103 is fixedly connected to the inner wall of the guide rail 1101, and the other end of the spring D1103 is fixedly connected to the top of the slider 1102. When the slider 1102 is subjected to an external force, the spring D1103 can store elastic potential energy and push the slider 1102 to return to its initial position after the force disappears.

[0054] See Figure 8As shown, the driving mechanism includes an exhaust pipe 1205 installed at the top end of the inside of the tester 2, a connecting rod 1206 is sliding inside the exhaust pipe 1205, one end of the connecting rod 1206 is fixedly connected to one side of the mounting base 4, a movable plug 1207 is fixedly connected to the top of the connecting rod 1206, a sleeve 1208 is fixedly installed at the bottom end of the inside of the tester 2, the exhaust pipe 1205 and the sleeve 1208 are connected through a connecting pipe B1209, a push rod 1210 is sliding inside the sleeve 1208, and a rack B1211 is fixedly connected to one side of the push rod 1210 passing through the sleeve 1208, the gear B1203 is meshed with the rack B1211, and a one-way suction valve and a one-way exhaust valve are installed on the outer wall of the exhaust pipe 1205.

[0055] See Figure 2 As shown, a test carrier substrate is installed at the bottom of the interior of the tester 2. The test carrier substrate is made of an antistatic board, which can effectively prevent the accumulation and release of static electricity, avoiding damage to sensitive components on the circuit board due to electrostatic discharge.

[0056] Working principle: Place the circuit board to be tested on the surface of the test table 7, start the air pump 8, and the gas generated by the air pump 8 is transported to the inside of the sleeve 905 through the connecting pipe A907, so that the gas pressure in the sleeve 905 increases, and the increased gas pushes the slide bar 906 to move outward. The movement of the slide bar 906 drives the clamping plate 901 to move synchronously to both sides of the circuit board, so that the clamping plate 901 pushes the clamping block 904 to clamp both sides of the circuit board, thereby achieving the effect of clamping and fixing the circuit board placed on the test table 7, avoiding the circuit board placed on the test table 7 being subjected to external force collision during the operation of the tester 2, resulting in displacement of the circuit board, thereby causing errors in the test of the tester 2, and improving the detection accuracy of the device;

[0057] According to the different thickness models of the circuit board, when the circuit board to be tested is placed on the test table 7, the staff can lift the measuring rod 1104 and move it so that the contact head 1105 at the bottom of the measuring rod 1104 contacts the top of the circuit board. During the movement of the measuring rod 1104, the measuring rod 1104 synchronously drives the slider 1102 to move along the inner wall of the guide rail 1101, so that the slider 1102 drives the L-shaped rod 1106 to move, and the L-shaped rod 1106 drives the rack A1107 at its top to move. The meshing relationship between rack A1107 and ring gear 1109 enables rack A1107 to drive control rod 1108 to rotate, thereby adjusting the opening of throttle valve 1007 by rotating control rod 1108. The air intake speed is adjusted according to the thickness of the circuit board, so that the air pressure is applied to the circuit board slowly and evenly, reducing the risk of bending and cracking caused by instantaneous excessive air pressure due to air pressure shock, protecting the integrity of the circuit board, and eliminating the need for manual intervention, greatly saving detection time and labor costs, and improving test efficiency and reliability;

[0058] After the circuit board is fixed, the cylinder 3 is started, and the cylinder 3 drives the mounting base 4 to move downward, thereby causing the probe 1003 at the bottom end of the mounting base 4 to move downward synchronously until the needle tip of the probe 1003 contacts the solder point on the surface of the circuit board. The solenoid valve 1008 on the surface of the control connecting pipe A907 is opened, and the gas enters the air cavity 1005 inside the mounting base 4 through the connecting pipe A907. Subsequently, the gas enters the circular tube 1001 through the air cavity 1005, so that the gas pushes the piston 1002 to move downward, and the movement of the piston 1002 drives the probe 1003 to weld. Pressure is applied to the weld point. A normal weld can withstand a certain pressure, but a cold weld will have abnormal displacement when the weld point is under pressure. If the probe 1003 at the cold weld is pressed deeper than the probe 1003 at a normal weld by a certain threshold, the displacement sensor on the top of the piston 1002 will convert the measured value into an electrical signal and transmit it to the external display. The staff can visually observe the specific position of the cold weld through the external display, so as to quickly locate the welding defect, accurately identify the cold weld, and improve the detection efficiency and accuracy.

[0059] When the cylinder 3 drives the mounting seat 4 to move downward, the mounting seat 4 drives the connecting rod 1206 on one side to move downward synchronously, and the connecting rod 1206 drives the movable plug 1207 to slide down along the inside of the exhaust pipe 1205, so that the movable plug 1207 sucks the external gas into the interior of the exhaust pipe 1205 through the one-way suction valve. When the pressure detection is completed, the cylinder 3 drives the mounting seat 4 to move upward, so that the mounting seat 4 drives the connecting rod 1206 to move upward synchronously, so that the connecting rod 1206 drives the movable plug 1207 to move upward, and the movable plug 1207 compresses the gas inside the exhaust pipe 1205 into the interior of the sleeve 1208 through the connecting pipe B1209, so that the gas inside the sleeve 1208 As the pressure increases, the gas pushes the push rod 1210 to move, and the push rod 1210 further pushes the rack B1211 to move. Due to the meshing relationship between the rack B1211 and the gear B1203, the rack B1211 drives the gear B1203 to rotate, and the gear B1203 drives the rotating rod 1202 to rotate synchronously, so that the rotating rod 1202 drives the cam 1204 to rotate synchronously, thereby utilizing the rotation of the cam 1204 to vibrate the test bench 7. The stress generated by the vibration will cause the cracks in the solder joints to expand, and the solder joints will shake abnormally, thereby effectively detecting such solder joints with internal cracks, and preventing the circuit board from being damaged due to solder joint failure during use.
