[0058] The following will describe the specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0059] As Figure 1 shown, the circuit board testing device provided in this embodiment includes: a detection device body 1, a push-pull slide plate 2, a safety partition 3, and a locking assembly; the detection device body 1 is of a box structure, a through hole is opened on the side of the detection device body, and a detection chamber is formed by enclosing the inside of the detection device body 1.

[0060] The push-pull slide plate 2 is slidably installed in the detection chamber, and the push of the push-pull slide plate 2 can be realized through a slide rail structure. The push-pull slide plate 2 is used to place the circuit board body 5. Specifically, as Figure 6 shown, the circuit board testing device further includes a circuit board tooling 6. The circuit board tooling 6 is used to place the circuit board body 5. A plurality of uniformly distributed positioning screw holes 201 are opened at the top of the push-pull slide plate 2, and the circuit board tooling 6 is locked to the top of the push-pull slide plate 2 through a plurality of positioning bolts 7 adapted to the positioning screw holes 201.

[0061] The safety partition 3 is connected to the end of the push-pull slide plate 2 extending out of the detection chamber. The included angle between the installation partition and the push-pull slide plate 2 is 90°, that is, the push-pull slide plate 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.

[0062] One side of the safety partition 3 is provided with an observation hole, and a transparent observation plate 4 is assembled inside the observation hole. Two operation holes 401 are provided on the side wall of the transparent observation plate 4 near the bottom for the operator to put both hands into the detection chamber.

[0063] The locking assembly is installed on the detection device body 1. 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 in the position of 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.

[0064] Regarding the structure and shape of the locking assembly, specifically:

[0065] As Figure 2 、 Figure 3 shown, the locking assembly includes a sliding sleeve 9, a latch plate 10, an adsorption plate 11 and an electromagnet 12; the sliding sleeve 9 is fixedly installed on the detection device body 1, and the sliding sleeve 9 can be fixed on the detection device main body by welding. A through hole is provided in the middle of the sliding sleeve 9 to enable the latch plate 10 to pass through the sliding sleeve 9, and the latch plate 10 can move along the sliding sleeve 9.

[0066] The top of the latch plate 10 extends out of the end of the sliding sleeve 9 and is connected to the adsorption plate 11, so that the latch plate 10 and the adsorption plate 11 are an integral body. 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 sliding sleeve 9. Under the action of its own gravity, normally, the adsorption plate 11 abuts against the top of the sliding sleeve 9.

[0067] The bottom of the latch plate 10 has a clamping groove, and a locking rod 8 is fixedly arranged on the detection device body 1. In the locked state, the locking rod 8 extends into the clamping groove to limit the safety partition 3 in the position of blocking the through hole.

[0068] In order to control the upward movement of the latch plate 10, the electromagnet 12 is fixedly arranged on the detection device body 1, and the electromagnet 12 is located above the adsorption plate 11. The electromagnet 12 has a powered-on state and a powered-off state. When unlocking is required, the electromagnet 12 is in the powered-on state, and the electromagnet 12 generates a magnetic force on the adsorption plate 11 to drive the adsorption plate 11 and the latch plate 10 to move upward together, so that the locking rod 8 disengages from the clamping groove. At this time, the safety partition 3 can be freely pushed to push the circuit board body 5 out of the detection chamber.

[0069] After the locking rod 8 disengages from the clamping groove, the electromagnet 12 switches to the powered-off state, and the latch 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.

[0070] The bottom outer side of the collision lock plate 10 has a guiding inclined surface. When the push-pull sliding plate 2 and the safety partition 3 are pushed back, the lock rod 8 will contact the guiding inclined surface at the bottom end of the collision lock plate 10. Since the guiding inclined surface is an inclined surface, the collision lock plate 10 is squeezed to slide upward until the lock rod 8 is re-engaged with the engaging groove of the collision lock plate 10, completing the re-locking of the safety partition 3.

[0071] In an alternative embodiment, the locking assembly further includes an unlocking button 13; the unlocking button 13 is disposed on the safety partition 3, and the unlocking button 13 is electrically connected to the electromagnet 12 through a control circuit. The unlocking button 13 is used to control the electromagnet 12 to switch between the energized state and the de-energized state.

[0072] The safety partition 3 is provided with a push-pull grip 28, and the push-pull grip 28 is located below the unlocking button 13, facilitating the operator to press the unlocking button 13 while holding the push-pull grip 28.

[0073] In addition, it should be noted that the locking assembly can be set in two groups, and lock rods 8 are correspondingly provided on both the left and right sides of the safety partition 3. The two groups of locking assemblies are symmetrically disposed on the main body of the detection device, and the locking and unlocking of the safety partition 3 are realized through the two groups of locking assemblies and the two lock rods 8.

[0074] In summary, by setting the push-pull slide plate 2 and the safety partition plate 3, before detecting the circuit board body 5, the circuit board body 5 and the supporting circuit board tooling 6 are first assembled together. Press any unlocking button 13 to make the two electromagnets 12 adsorb the adsorption plate 11, drive the two latch plates 10 to slide upward, so as to disengage from the lock rod 8, and the latch plates 10 release the locking of the lock rod 8. At this time, the push-pull grip 28 can be pulled to pull the push-pull slide plate 2 out of the detection chamber. 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 designated position on the push-pull slide plate 2 by a plurality of positioning bolts 7. After that, the push-pull slide plate 2 and the safety partition plate 3 are pushed back into the detection hole. Since the unlocking button 13 was released after pulling out the push-pull slide plate 2 before, the micro electromagnet 12 is in a power-off state at this time, and the latch plate 10 slides down and resets. When the push-pull slide plate 2 and the safety partition plate 3 are pushed back, the lock rod 8 will contact the guiding inclined surface at the bottom end of the latch plate 10, thereby squeezing the latch plate 10 to slide upward until the lock rod 8 is re-locked with the latch plate 10, completing the re-locking of the safety partition plate 3, and the safety partition plate 3 and the transparent observation plate 4 isolate the circuit board body 5 and the detection equipment inside the detection chamber. Then, the detection personnel can wear insulating gloves and put their hands into the two operation holes 401 respectively, pick up the detection equipment to detect the circuit board body 5, so that the safety partition plate 3, the transparent observation plate 4 and the insulating gloves form a safety protection isolation belt, separating the detection personnel from the circuit board body 5 and the electrical equipment, improving the operation safety, reducing the operation risk, and at the same time effectively greatly reducing the interference of external environmental factors on the detection process and results of the circuit board body 5, ensuring the accuracy of the detection results.

[0075] Moreover, the unlocking of the transparent observation plate 4 is controlled by the unlocking button 13, and the unlocking button 13 is located above the push-pull grip 28. The detection personnel can press the unlocking button 13 while holding the push-pull grip 28, so that the unlocking and pulling actions can be smoothly connected. When the safety partition plate 3 is pushed back, the lock rod 8 will automatically dock with the latch plate 10, making the unlocking and locking operations of the safety partition plate 3 simple, fast and very convenient.

[0076] In an optional embodiment, as Figure 9 shown, the circuit board testing equipment further includes a surrounding plate 14; the surrounding plate 14 includes a connecting plate and a baffle plate. Both ends of the connecting plate are connected with baffle plates, and the baffle plates are arranged at an angle with the connecting plate. The connecting plate and the two baffle plates at both ends form a C-shaped surrounding plate 14. The connecting plate is connected to the outer side surface of the bottom of the safety partition plate 3, so that the surrounding plate 14 and the installation partition plate are connected into an integral structure.

[0077] The inner side of the baffle is equipped with a hook 15, and the hook 15 is used to hang an anti-static bracelet 16. The top of the baffle is equipped with a conductive rack 17, and the conductive clip of the anti-static bracelet 16 is clipped on the conductive rack 17. By setting the anti-static bracelet 16, before the tester wears insulating gloves, an anti-static bracelet 16 is tied to each wrist first, and then the insulating gloves are put on and extended into the test chamber to start the test operation. The anti-static bracelet 16 can ground the tester's body during the test process, thereby discharging the static electricity carried by the tester's body, and cooperating with the insulating gloves to prevent static electricity from damaging the components on the circuit board body 5, playing a role in static electricity protection.

[0078] In an alternative embodiment, as Figure 3 shown, the circuit board testing device further includes a heater 20; the heater 20 is installed on the safety partition 3, and heat conduction plates 21 are installed on both outer sides of the transparent observation plate 4. The heater 20 is electrically connected to the heat conduction plates 21 so that the heater 20 can heat the transparent observation plate 4 through the heat conduction plates 21.

[0079] By setting the heater 20, during the process of the tester detecting the circuit board body 5, the heater 20 will heat the two heat conduction plates 21, and then heat the surface of the transparent observation plate 4, causing the transparent observation plate 4 to start to heat up, so that the temperature of the transparent observation plate 4 is significantly higher than the temperature inside and outside the test chamber and higher than the temperature of the tester's exhaled gas, thereby preventing condensation from forming on the inner and outer walls of the transparent observation plate 4 due to temperature difference, forming water mist and affecting the tester's observation of the inside of the test chamber, and at the same time preventing the condensed water from condensing into water droplets and dripping, affecting the electrical safety inside the test chamber.

[0080] The heater 20 can be set as a resistance heater 20, and the heat conduction plate 21 is made of a high-resistance material, such as nickel-chromium alloy or carbon fiber. The resistance heater 20 generates heat by passing an electric current through the high-resistance material, thereby heating the transparent observation plate 4.

[0081] In an alternative embodiment, as Figure 4 、 Figure 7 shown, two defogging guide rails 22 are horizontally installed on each of the inner and outer walls of the transparent observation plate 4, for a total of four defogging guide rails 22, and there is a spacing between the two defogging guide rails 22 on the same side, that is, the two defogging guide rails 22 on the same side are arranged one above the other. A vertical defogging rod 23 is slidably installed between the two defogging guide rails 22 on the same side. The defogging rod 23 is closely attached to the transparent observation plate 4. A magnetic strip 24 is installed inside the defogging rod 23 so that the two defogging rods 23 attract each other, so that the two defogging rods 23 on both sides of the transparent observation plate 4 can move together, thereby using the defogging rod 23 to wipe the transparent observation plate 4.

[0082] In addition, the sliding connection between the defogging guide rail 22 and the defogging rod 23 can adopt the way of a sliding groove. For example, a sliding groove is opened on the defogging guide rail 22, and sliding protrusions are arranged at both ends of the defogging rod 23. The sliding protrusions extend into the sliding groove, so that the defogging rod 23 slides along the sliding groove.

[0083] As Figure 8 shown, a push-pull rod 25 is connected to the defogging rod 23 located outside the transparent observation plate 4. The push-pull rod 25 is used to drive the defogging rod 23 to slide along the defogging guide rail 22. When the indoor temperature is too low, resulting in a slow heating rate of the transparent observation plate 4 and it fails to heat up in time, water mist will be generated on the surface of the transparent observation plate 4. At this time, the tester can hold the push-pull rod 25 and pull the defogging rod 23 to wipe on the outer surface of the transparent observation plate 4.

[0084] In an alternative embodiment, as Figure 5 shown, water guide pipes 26 are installed at the bottom of the defogging guide rails 22 located below the inner and outer walls of the transparent observation plate 4. A water storage tank 27 is arranged at the bottom of the push-pull sliding plate 2. The water guide pipes 26 are communicated with the water storage tank 27, so that the water droplets wiped from the transparent observation plate 4 slide into the defogging guide rail 22 and then flow into the water storage tank 27 through the water guide pipes 26, thereby preventing excessive water storage in the defogging guide rail 22, resulting in overflow or rust.

[0085] In an alternative embodiment, the circuit board testing device further includes a humidifier 18; the humidifier 18 is arranged on one side of the bottom of the testing device body 1. The air output end of the humidifier 18 is connected to an air pipe 19, and the air pipe 19 leads into the testing chamber. The humidifier 18 regularly releases water vapor into the testing device body 1 through the air pipe 19 to increase the air humidity inside the testing device body 1, thereby significantly reducing the generation of static electricity inside the testing chamber, reducing static electricity damage, and effectively preventing the occurrence of electric leakage and discharge in the testing chamber due to component damage or circuit short circuit of the circuit board body 5.

[0086] 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. Through the cooperation of the defogging guide rail 22 and the defogging rod 23, the water mist on the transparent observation plate 4 is eliminated. Therefore, the situation that the humidifier 18 causes water mist on the surface of the transparent observation plate 4 will not occur.

[0087] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
