[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] like Figure 1As shown, the circuit board testing equipment provided in this embodiment includes: a testing equipment body 1, a push-pull slide plate 2, a safety partition 3 and a locking assembly; the testing equipment body 1 is a box-type structure, a through hole is opened on the side of the testing equipment body, and the interior of the testing equipment body 1 is enclosed to form a testing room.

[0025] The push-pull slide plate 2 is slidably installed in the detection room, and the push-pull slide plate 2 can be pushed by the slide rail structure. The push-pull slide plate 2 is used to place the circuit board body 5. Specifically, Figure 6 As shown, the circuit board testing equipment also includes a circuit board fixture 6, which is used to place the circuit board body 5. A plurality of evenly distributed positioning screw holes 201 are provided on the top of the push-pull slide 2. The circuit board fixture 6 is locked on the top of the push-pull slide 2 by a plurality of positioning bolts 7 that are compatible with the positioning screw holes 201.

[0026] The safety partition 3 is connected to the end of the push-pull slide 2 extending out of the detection chamber. The angle between the installation partition and the push-pull slide 2 is 90°, that is, the push-pull slide 2 is horizontally arranged and the installation partition is vertically arranged. The safety partition 3 can block the through hole, so that when the safety partition 3 blocks the through hole, the detection chamber is isolated from the outside world.

[0027] An observation hole is provided on one side of the safety partition 3, and a transparent observation plate 4 is installed inside the observation hole. Two operation holes 401 are provided on the side wall of the transparent observation plate 4 near the bottom, so that operators can put their hands into the detection room.

[0028] The locking assembly is installed on the detection device body 1, and the locking assembly has a locked state and an unlocked state, and the locking assembly is configured to be able to switch between the locked state and the unlocked state; when the locking assembly is in the locked state, the locking assembly is connected to the safety partition 3 to limit the safety partition 3 to a position blocking the through hole; when the locking assembly is in the unlocked state, the safety partition 3 can move relative to the detection device body 1.

[0029] Regarding the structure and shape of the locking assembly, specifically: like Figure 2 , Figure 3 As shown, the locking assembly includes a sleeve 9, a strike plate 10, an adsorption plate 11 and an electromagnet 12; the sleeve 9 is fixedly mounted on the detection device body 1, and the sleeve 9 can be fixed on the detection device body by welding. A through hole is provided in the middle of the sleeve 9 so that the strike plate 10 can pass through the sleeve 9, and the strike plate 10 can move along the sleeve 9.

[0030] The top of the strike plate 10 extends out of the end of the sliding sleeve 9 and is connected to the adsorption plate 11, so that the strike plate 10 and the adsorption plate 11 are integrated. It should be noted that the size of the adsorption plate 11 is larger than the size of the through hole, so that the adsorption plate 11 cannot extend into the interior of the sliding sleeve 9. Under the action of its own gravity, the adsorption plate 11 abuts against the top of the sliding sleeve 9 in normal state.

[0031] The bottom of the strike plate 10 has a snap-in groove, and the detection device body 1 is fixedly provided with a lock rod 8. In the locked state, the lock rod 8 extends into the snap-in groove to limit the safety partition 3 at a position to block the through hole.

[0032] In order to control the upward movement of the strike plate 10, the electromagnet 12 is fixedly arranged on the detection equipment body 1, and the electromagnet 12 is located above the adsorption plate 11. The electromagnet 12 has a power-on state and a power-off state. When unlocking is required, the electromagnet 12 is in the power-on state, and the electromagnet 12 generates a magnetic force on the adsorption plate 11 to drive the adsorption plate 11 and the strike plate 10 to move upward together, so that the locking rod 8 is disengaged from the card slot. At this time, the safety partition 3 can be pushed freely to push the circuit board body 5 out of the detection chamber.

[0033] After the locking rod 8 is disengaged from the engaging groove, the electromagnet 12 is switched to the power-off state, and the strike plate 10 and the adsorption plate 11 move downward due to gravity, and the adsorption plate 11 abuts against the top of the sliding sleeve 9 to prepare for subsequent re-locking.

[0034] The bottom outer side surface of the strike plate 10 has a guiding slope. When the push-pull slide plate 2 and the safety partition 3 are pushed back, the locking rod 8 will contact the guiding slope at the bottom end of the strike plate 10. Since the guiding slope is an inclined surface, the strike plate 10 is squeezed to slide upward until the locking rod 8 and the locking groove of the strike plate 10 are re-engaged together, thereby completing the re-locking of the safety partition 3.

[0035] In an optional embodiment, the locking assembly further includes an unlocking button 13; the unlocking button 13 is disposed on the safety partition 3, the unlocking button 13 is electrically connected to the electromagnet 12 through a control circuit, and the unlocking button 13 is used to control the electromagnet 12 to switch between a power-on state and a power-off state.

[0036] The safety partition 3 is provided with a push-pull handle 28 , which is located below the unlocking button 13 , so that the operator can press the unlocking button 13 while holding the push-pull handle 28 .

[0037] In addition, it should be noted that the locking assembly can be set into two groups, and locking rods 8 are provided on the left and right sides of the safety partition 3 respectively. The two groups of locking assemblies are symmetrically arranged on the main body of the detection equipment, and the locking and unlocking of the safety partition 3 are achieved by the two groups of locking assemblies and the two locking rods 8.

[0038] In summary, by setting the push-pull slide plate 2 and the safety partition plate 3, before inspecting the circuit board body 5, the circuit board body 5 and the matching circuit board tooling 6 are first assembled together, and any one of the unlocking buttons 13 is pressed to make the two electromagnets 12 adsorb the adsorption plate 11, drive the two lock plates 10 to slide upward, thereby disengaging from the locking rod 8, so that the lock plate 10 releases the lock of the locking rod 8. At this time, the push-pull handle 28 can be pulled to pull the push-pull slide plate 2 out of the inspection room, and then the circuit board tooling 6 is placed on the push-pull slide plate 2, and the circuit board tooling 6 is locked at the specified position on the push-pull slide plate 2 by using multiple positioning bolts 7, and then the push-pull slide plate 2 and the safety partition plate 3 are pushed back into the inspection hole. Since the unlocking button 13 was released after the push-pull slide plate 2 was pulled out, the micro electromagnet 12 is in a power-off state at this time, and the lock plate 10 slides down and resets. When the push-pull slide plate 2 and When the safety partition 3 is pushed back, the locking rod 8 will contact the guiding slope at the bottom end of the strike plate 10, thereby squeezing the strike plate 10 to make it slide up, until the locking rod 8 and the strike plate 10 are re-engaged together, completing the re-locking of the safety partition 3, so that the safety partition 3 and the transparent observation plate 4 isolate the circuit board body 5 and the detection equipment inside the detection room, and then the detection personnel can put on insulating gloves and put their hands into the two operating holes 401 respectively, pick up the detection equipment to detect the circuit board body 5, so that the safety partition 3, the transparent observation plate 4 and the insulating gloves form a safety protection isolation belt, which separates the detection personnel from the circuit board body 5 and electrical equipment, improves the safety of operation, reduces the operation risk, and at the same time effectively and significantly reduces the interference of external environmental factors on the detection process and detection results of the circuit board body 5, thereby ensuring the accuracy of the detection results.

[0039] In addition, the unlocking of the transparent observation panel 4 is controlled by the unlocking button 13, and the unlocking button 13 is located above the push-pull handle 28. The inspector can press the unlocking button 13 while holding the push-pull handle 28, so that the unlocking and pulling actions can be smoothly connected. When the safety partition 3 is pushed back, the locking rod 8 will automatically dock with the strike plate 10, making the unlocking and locking operations of the safety partition 3 simple, fast and very convenient.

[0040] In an optional embodiment, if Fig. 9 As shown, the circuit board testing equipment also includes an enclosure 14; the enclosure 14 includes a connecting plate and a baffle, both ends of the connecting plate are connected with baffles, and the baffles and the connecting plate are set at an angle, the connecting plate and the two baffles at both ends form a C-shaped enclosure 14, and the connecting plate is connected to the bottom outer side surface of the safety partition 3, so that the enclosure 14 and the installation partition are connected to form an integrated structure.

[0041] A hook 15 is installed on the inner side of the baffle, and the hook 15 is used to hang an anti-static wristband 16. A conductive frame 17 is installed on the top of the baffle, and the conductive clip of the anti-static wristband 16 is clamped on the conductive frame 17. By setting the anti-static wristband 16, before the inspector puts on insulating gloves, he first ties an anti-static wristband 16 on each wrist, then puts on insulating gloves and reaches into the inspection room to start the inspection operation. The anti-static wristband 16 can ground the body of the inspector during the inspection process, thereby conducting out the static electricity carried in the body of the inspector, and cooperate with the insulating gloves to prevent static electricity from damaging the components on the circuit board body 5, thereby playing a role in electrostatic protection.

[0042] In an optional embodiment, if Figure 3 As shown, the circuit board testing equipment also includes a heater 20; the heater 20 is installed on the safety partition 3, and heat conducting plates 21 are installed on both sides of the outside of the transparent observation plate 4. The heater 20 is electrically connected to the heat conducting plates 21 so that the heater 20 can heat the transparent observation plate 4 through the heat conducting plates 21.

[0043] By setting up the heater 20, during the process of the inspector inspecting the circuit board body 5, the heater 20 will heat the two heat-conducting plates 21, and then heat the surface of the transparent observation plate 4, so that the transparent observation plate 4 starts to heat up, so that the temperature of the transparent observation plate 4 is significantly higher than the air temperature inside and outside the inspection room, and higher than the temperature of the exhaled gas of the inspector, thereby preventing condensation from forming on the inner and outer walls of the transparent observation plate 4 due to the temperature difference, forming water mist that affects the inspector's observation of the inside of the inspection room, and at the same time preventing the condensation from condensing into water droplets and dripping, affecting the electrical safety inside the inspection room.

[0044] The heater 20 can be set as a resistance heater 20, and the heat conductive plate 21 is set as a high resistance material, such as nickel-chromium alloy or carbon fiber. The resistance heater 20 generates heat by passing current through the high resistance material, thereby heating the transparent observation plate 4.

[0045] In an optional embodiment, if Figure 4 , Figure 7 As shown, two defogger rails 22 are horizontally installed on the inner and outer walls of the transparent observation plate 4, with a total of four defogger rails 22, and there is a spacing between the two defogger rails 22 on the same side, that is, the two defogger rails 22 on the same side are arranged one above the other, and a vertical defogger rod 23 is slidably installed between the two defogger rails 22 on the same side, and the defogger rod 23 is tightly attached to the transparent observation plate 4. A magnetic strip 24 is installed inside the defogger rod 23 to allow the two defogger rods 23 to adsorb each other, so that the two defogger rods 23 on both sides of the transparent observation plate 4 can move together, so that the defogger rods 23 can be used to wipe the transparent observation plate 4.

[0046] In addition, the sliding connection between the defogger guide rail 22 and the defogger rod 23 can adopt a sliding groove. For example, a sliding groove is opened on the defogger guide rail 22, and sliding protrusions are set at both ends of the defogger rod 23. The sliding protrusions extend into the sliding groove, so that the defogger rod 23 slides along the sliding groove.

[0047] like Figure 8 As shown, the defogger rod 23 located on the outside of the transparent observation plate 4 is connected to a push-pull rod 25, which is used to drive the defogger rod 23 to slide along the defogger guide rail 22. When the indoor temperature is too low, the transparent observation plate 4 heats up slowly and fails to heat up in time, water mist will be generated on the surface of the transparent observation plate 4. At this time, the inspector can hold the push-pull rod 25 and pull the defogger rod 23 to wipe the outer surface of the transparent observation plate 4.

[0048] In an optional embodiment, if Figure 5 As shown, the inner and outer walls of the transparent observation plate 4 are both provided with a water pipe 26 at the bottom of the defogger rail 22 below, and a water tank 27 is provided at the bottom of the push-pull slide plate 2. The water pipe 26 is connected with the water tank 27 so that the water droplets wiped by the transparent observation plate 4 can slide into the defogger rail 22, and then flow into the water tank 27 through the water pipe 26, thereby preventing excessive water from accumulating in the defogger rail 22, causing overflow or rust.

[0049] In an optional embodiment, the circuit board testing equipment also includes a humidifier 18; the humidifier 18 is arranged on one side of the bottom of the detection equipment body 1, and the air supply end of the humidifier 18 is connected to the ventilation pipe 19, and the ventilation pipe 19 leads into the detection room. The humidifier 18 regularly releases water vapor into the detection equipment body 1 through the ventilation pipe 19 to increase the air humidity inside the detection equipment body 1, thereby significantly reducing the generation of static electricity inside the detection room, reducing static electricity damage, and effectively preventing leakage and discharge inside the detection room due to damage to components of the circuit board body 5 or circuit short circuit.

[0050] In addition, it should be noted that the setting of the humidifier 18 will cause water mist on the surface of the transparent observation plate 4. The water mist on the transparent observation plate 4 is eliminated through the cooperation of the defogger rail 22 and the defogger rod 23. Therefore, the humidifier 18 will not cause water mist on the surface of the transparent observation plate 4.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
