They are very commonly used, and circuit boards usually need to be tested for waterproofing when they are used. Based on existing technology, it has been found that in the existing inspection process, during the spray inspection of circuit boards, due to the unreasonable setting of the circuit board angle, water is difficult to spray all parts comprehensively and evenly.

DETAILED DESCRIPTION
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.
[0022] Example 1: A new energy vehicle circuit board waterproof performance test equipment, based on Figure 1-Figure 4 As shown, it includes a box body 1 and a box door 11; the box door 11 is installed on the box body 1; It also includes a drive assembly, a fixed plate 205, a connecting shaft 206, an electric clamp 207, a conduit 208, a spray pipe 209, a spur gear I 210, a motor I 211 and a spur gear II 212; two drive assemblies are installed on the box body 1; each drive assembly is installed with two fixed plates 205; each fixed plate 205 is connected to a connecting shaft 206; each connecting shaft 206 is installed with an electric clamp 207 at one end away from the fixed plate 205; a conduit 208 is installed on the box body 1, and a two-way nozzle is provided in the middle of the conduit 208, and unidirectional nozzles are provided at both ends of the conduit 208; each connecting shaft 206 is fixed with a spur gear I 210; a motor I 211 is installed at the bottom inside the box body 1; a spur gear II 212 is fixed to the output shaft of the motor I 211.
[0023] The clamping portion of the electric clamp 207 is provided with a wavy rubber block to reduce damage to the circuit board 2 when clamping and limiting the circuit board 2.
[0024] The drive assembly includes an electric slide rail I 201, an electric slider I 202, an electric slide rail II 203 and an electric slider II 204; two electric slide rails I 201 are fixedly connected to the upper inner side of the box body 1; each electric slide rail I 201 is slidably connected to an electric slider I 202; each electric slider I 202 is fixedly connected to an electric slide rail II 203; each electric slide rail II 203 is slidably connected to two electric sliders II 204; each electric slider II 204 is fixedly connected to a fixed plate 205.
[0025] The external pump for water delivery is connected to the conduit 208 in advance, and then the box door 11 is opened. With the front side of the box body 1 as the reference, the initial positions of all the electric clamps 207 are located on the inner left side of the box body 1 to facilitate loading and unloading. Then, two circuit boards 2 are placed into the box body 1 in sequence by manual or external robotic arms, and both circuit boards 2 are powered on. Then, all the electric clamps 207 are controlled to operate and clamp the two circuit boards 2 respectively. Figure 4As shown, the two electric sliders Ⅰ 202 are then controlled to move to the right along an electric slide rail Ⅰ 201 respectively. The movement of the two electric sliders Ⅰ 202 drives all connected components to move, and then drives all electric clamps 207 to move, and then drives the two circuit boards 2 to move, and makes the two circuit boards 2 located directly below the spray pipe 209. Then, the external pump for water supply is controlled to start to supply water into the conduit 208. The water flows along the conduit 208 and sprays onto the surface of the circuit board 2. The water is sprayed onto the lower surface of the circuit board 2 located above and the upper surface of the circuit board 2 located below through the two-way nozzle provided in the middle of the conduit 208, so that the upper and lower surfaces of the two circuit boards 2 are sprayed with high-pressure water. At this time, the external visual detector is used to observe whether the circuit board 2 can operate normally when powered on, so as to determine whether the waterproof performance of the circuit board 2 is qualified, thereby realizing the waterproof performance test of the circuit board 2.
[0026] However, in the existing inspection process, the spraying operation on the circuit board 2 is often not properly set at an angle, resulting in water not being able to fully and evenly spray all parts of the circuit board 2. As a result, some areas may not be adequately covered by the water flow, making it difficult to effectively detect potential defects, thereby affecting the accuracy of the inspection results. As a result, some defective circuit boards 2 may flow into subsequent production links, resulting in an increase in product defect rates. To solve the above problem, the two electric sliders II 204 located above are controlled to move downward along the corresponding electric slide rails II 203, and the two electric sliders II 204 located below are controlled to move upward along the corresponding electric slide rails II 203. The movement of the electric sliders II 204 drives the fixed plate 205 to move, and then drives all connected components to move, so that the two circuit boards 2 move toward each other, and at the same time, the corresponding two spur gears I 210 are engaged with the spur gear II 212. Then the motor I 211 is controlled to start, and the output shaft of the motor I 211 rotates to drive the spur gear II 212 to rotate. The rotation of the spur gear II 212 drives the two spur gears I 210 to rotate. The rotation of the two spur gears I 210 each drives a connecting shaft 206 to rotate. The rotation of the connecting shaft 206 drives the electric clamp 207 to rotate, so that the two circuit boards 2 rotate, and then the angle of the circuit board 2 is adjusted so that water can be sprayed more comprehensively to various parts of the circuit board 2, thereby improving the accuracy of the detection. By simultaneously testing the waterproof performance of the two circuit boards 2, the two circuit boards 2 form a control group, and the detection efficiency is improved.
[0027] Example 2: Based on Example 1, Figure 5-Figure 6As shown, it also includes a vibration simulation system; the vibration simulation system is connected to the box body 1; the vibration simulation system includes a long strip 301, a protrusion 302, a cross bar 303, a sliding block 304, a fixed ring 305 and an elastic member 306; two long strips 301 are fixed to the box body 1; each long strip 301 is fixed with a number of protrusions 302; two cross bars 303 are fixed to the inner side of each fixed plate 205; each cross bar 303 is slidably connected to a sliding block 304; all sliding blocks 304 in the same fixed plate 205 are fixed to a fixing ring 305; each fixing ring 305 is rotatably connected to a corresponding connecting shaft 206; an elastic member 306 is sleeved on the outside of each cross bar 303, the elastic member 306 is a spring, one end of the elastic member 306 is fixed to the sliding block 304, and the other end of the elastic member 306 is fixed to the fixed plate 205.
[0028] The sizes of the bumps 302 are different to simulate vibrations of different degrees.
[0029] Since the circuit board 2 will vibrate with the vibration of the equipment during actual use, and the vibration and splashing of the car exist at the same time, and the two environmental factors also affect each other, which can easily cause the circuit board 2 to malfunction during use, affecting the normal operation of the equipment. By controlling the two electric sliders I 202 to move to the right along an electric slide rail I 201, all the connected components are driven to move, and the two circuit boards 2 are driven to move, and at the same time, the four connecting shafts 206 touch the corresponding long strips 301, and then all the electric sliders II 204 are controlled to start and move downward along the corresponding electric slide rails II 203. The electric slider II 204 moves to drive the fixed plate 205, and the fixed plate 205 moves to drive the corresponding cross bar 303, the sliding block 304, the fixed ring 305 and the elastic member 306 to move synchronously, and then drive the connecting shaft 206 to move to touch the protrusion 302, and is squeezed by the protrusion 302 to displace, and the connecting shaft 2 06 moves and drives the fixed ring 305 to move, and the movement of the fixed ring 305 drives the corresponding sliding block 304 to move, thereby compressing the corresponding elastic member 306. When the connecting shaft 206 moves away from the protrusion 302, the elastic force generated by the corresponding elastic member 306 drives all connected parts to move, thereby causing the connecting shaft 206 to move and reset, thereby causing the two circuit boards 2 to move back and forth, thereby simulating the vibration generated by the circuit board 2 during actual use, and then controlling the two electric sliders Ⅰ202 to move and reset to the left along an electric slide rail Ⅰ201, thereby causing the two circuit boards 2 to move and reset, and then controlling the external pump for water supply to start and supply water to the conduit 208, thereby spraying water on the surface of the circuit board 2 again, thereby achieving a waterproof performance test on the circuit board 2 after the circuit board 2 is vibrated, thereby improving the comprehensiveness and accuracy of the test by combining dynamic testing and static testing of the circuit board 2.
[0030] It should be noted that before the connecting shaft 206 touches the long strip 301, all the electric sliders II 204 are controlled to start moving toward each other along the corresponding electric slide rails II 203, so that the corresponding two spur gears I 210 are engaged with the spur gear II 212. Then, the motor I 211 is controlled to start, and the angle of the circuit board 2 is adjusted, thereby simulating the posture changes of the circuit board 2 when a car is driving on different road conditions (such as uphill, downhill, and flat roads). Then, the connecting shaft 206 is made to touch the corresponding long strip 301 in the same manner as above, thereby simulating the waterproof performance of the circuit board 2 that vibrates after the posture changes.
[0031] Example 3: Based on Example 2, Figure 2 、 Figure 3 and Figure 7-10 As shown, it also includes a partition detection system; the partition detection system is connected to the box 1; the partition detection system includes a vertical plate 12, a horizontal plate 13, an electric slide rail III 401, an electric slider III 402, a cover 403, a shielding curtain 404, a partition 405, a shielding plate 406, a seal 407, an air pipe 408 and an air inlet pipe 409; the vertical plate 12 is fixed to the middle of the inner side of the box 1; the horizontal plate 13 is fixed to the upper inner side of the box 1; the electric slide rail III 401 is fixed to the upper inner side of the box 1; the electric slider III 402 is slidably connected to the electric slide rail III 401; the electric slider III 402 is fixed to the upper inner side of the box 1 There is a cover shell 403; the cover shell 403 is slidably connected to the box body 1; a shielding curtain 404 is fixed to the cover shell 403, and a spring is provided inside the shielding curtain 404; a partition 405 is fixed to the upper inner side of the cover shell 403; a shielding plate 406 is fixed to the inner side of the cover shell 403; a plurality of seals 407 are fixed to the cover shell 403, and the seals 407 are rubber strips; two air pipes 408 are installed on the top of the box body 1; each air pipe 408 is fixed to and connected to an air intake pipe 409; all air intake pipes 409 are fixed to the horizontal plate 13, and all air intake pipes 409 pass through the box body 1 and the horizontal plate 13.
[0032] A guide rail is provided at the connection between the cover shell 403 and the box body 1 to facilitate the movement of the cover shell 403. The cover shell 403 and the guide rail cooperate to limit the water flowing to the bottom inside the box body 1, so that the water flows to the drain outlet on the box body 1.
[0033] A sealing strip is installed on the vertical plate 12 to cooperate with the partition 405 and the shielding plate 406 to separate the interior of the cover 403 into two independent spaces.
[0034] A sealing strip is provided on the side of the transverse plate 13 away from the box body 1 , so as to combine the box body 1 and the cover shell 403 to form a closed space.
[0035] The shielding curtain 404 is set to be transparent to facilitate manual observation and loading and unloading.
[0036] It also includes an electric actuator 501 and a rack 502; two electric actuators 501 are installed on the rear side of the box body 1. The electric actuators 501 are electric push rods, and the telescopic parts of all electric actuators 501 on the same side are fixedly connected to a rack 502.
[0037] The two external fans are connected to an air pipe 408 in advance. When the circuit board 2 is loaded and unloaded, the shielding curtain 404 is squeezed to deform the shielding curtain 404, thereby facilitating manual loading and unloading. Since the production environment and use environment of the circuit board 2 are complex and changeable, a single detection method often cannot fully cover all potential problems, especially in extreme environments such as high temperature, low temperature, and alternating hot and cold. It is difficult for traditional detection methods to effectively evaluate the reliability and stability of the circuit board 2. By controlling the electric slider III 402 to start moving along the electric slide rail III 401 toward the horizontal plate 13, the movement of the electric slider III 402 drives the cover shell 403 to move, and the movement of the cover shell 403 drives all connected components to move, thereby causing the cover shell 403 to move against the horizontal plate 13 and against the box body 1, as shown Figure 8 As shown, the cover 403, the horizontal plate 13 and the box body 1 are combined to form a closed space, and the movement of the cover 403 drives the partition 405 and the shielding plate 406 to move synchronously, so that when the cover 403 moves to abut the horizontal plate 13, the partition 405 and the shielding plate 406 are combined with the vertical plate 12, so that the interior of the cover 403 is divided into two independent spaces by the partition 405, the shielding plate 406 and the vertical plate 12, and the two independent spaces separated inside the cover 403 are made more sealed by the setting of the sealing member 407, and the two sides of the circuit board 2 are respectively isolated in the corresponding independent spaces by the partition 405, the shielding plate 406 and the vertical plate 12, as shown in FIG. Figure 9 As shown, the two external fans are then controlled to operate to deliver cold air and hot air to the corresponding air pipes 408, respectively, so that the gas flows along the air pipe 408 and the air inlet pipe 409 until it enters the cover 403, thereby making the temperature on one side of the circuit board 2 low and the temperature on the other side high, thereby simulating the state of the circuit board 2 being used in an extreme environment. The circuit board 2 is then subjected to high-pressure impact spraying with water to evaluate the performance of the circuit board 2 in the extreme environment, thereby further improving the comprehensiveness of the detection of the circuit board 2.
[0038] And after simulating the state of the circuit board 2 being used in an extreme environment, the circuit board 2 needs to be dried, and the electric slider III 402 is controlled to start and move along the electric slide rail III 401 to reset, so that the cover 403 moves away from the box body 1, and the partition 405 and the shielding plate 406 are synchronously moved away from the circuit board 2, and then all the electric sliders II 204 are controlled to move along the corresponding electric slide rail II 203, so that the two circuit boards 2 move away from each other, and thus both circuit boards 2 are away from the vertical plate 12, and then all the electric actuators 501 are controlled to start and drive the corresponding racks 502 to move, so that the two racks 502 move toward the direction of the spur gear I 210 on the same side until the racks 50 2 is meshed with the corresponding spur gear I 210, and then all the electric sliders II 204 are controlled to move along the corresponding electric slide rails II 203, thereby making all the spur gears I 210 move and rotate along the corresponding racks 502, thereby making the two circuit boards 2 rotate and tilt, so that the moisture remaining on the surfaces of the two circuit boards 2 can automatically flow away, and the two air inlet pipes 409 are still in the jet state, and then the gas is blown toward the circuit board 2 again to dry the circuit board 2, thereby achieving timely drying of the circuit board 2 after the waterproof performance test of the circuit board 2, avoiding moisture from staying on the circuit board 2 for a long time, and reducing the possibility of malfunction caused by residual moisture.
