Description

Technical Field

[0002] Electronic materials refer to materials used in electronic fields such as electronic devices, integrated circuits, and semiconductor devices. These materials usually have specific electrical, magnetic, optical and other properties, and can be used to manufacture various electronic components and electronic devices. Electronic materials include but are not limited to semiconductor materials, conductive materials, insulating materials, magnetic materials, etc. The water permeability of electronic materials directly affects the stability and reliability of electronic equipment. If the water permeability of electronic materials is high, it is easy to cause problems such as moisture and short circuit in electronic equipment, affecting the normal operation of the equipment. If the materials in electronic equipment have high water permeability, it may cause equipment damage, circuit short circuit and other problems, and even cause safety hazards such as fire. Therefore, measuring the water permeability of electronic materials helps protect the environment and personal safety. By measuring the water permeability of electronic materials, the materials can be optimized and improved to improve their waterproof performance, thereby improving the overall performance and service life of electronic equipment.

[0003] A Chinese patent with publication number CN218003180U discloses a device for detecting water permeability of electronic materials, which relates to the technical field of water permeability detection of electronic materials, and comprises a detection box, wherein side slide grooves are provided on both sides of the detection box, and the side slide grooves are slidably connected with receiving plates in a vertical direction, and the receiving plates are provided with two groups, and the two groups of receiving plates are connected by an intermediate hole.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 8The water permeability detection device of an electronic material shown in the figure comprises: a base 1, a mounting plate 2 is fixedly mounted on the top of the base 1, a placement groove for placing an electronic material board is arranged on the top of the mounting plate 2, a sealing ring is arranged inside the placement groove and a through hole is arranged at the bottom of the placement groove, a sliding column 4 is fixedly mounted on the top of the mounting plate 2, a first column 3 is fixedly mounted on the top of the mounting plate 2, and a collecting groove for collecting permeated water is fixedly mounted on the bottom of the base 1; a water injection mechanism is slidably mounted on the sliding column 4, a limiting cap 5 is installed on the top of the sliding column 4, the water injection mechanism is located above the mounting plate 2 and is adapted to be installed with the mounting plate 2, and the water injection mechanism is used to inject water into the top of the electronic material board; a pressing mechanism is hingedly mounted on both sides of the first column 3, and the pressing mechanism is used to press the water injection mechanism onto the electronic material board; a vibration mechanism is fixedly mounted on the top of the mounting plate 2, and the vibration mechanism is used to remove bubbles in the water injection mechanism;

[0029] When in use, first put the electronic material board into the placement groove in the mounting plate 2, and then press the clamping mechanism. Under the push of the clamping mechanism, the water injection mechanism is forced to slide downward and press on the electronic material board, so that the water injection mechanism and the electronic material board are tightly fitted. At this time, let go. Under the action of the clamping device, the water injection mechanism is still fitted on the electronic material board. After the water injection device reaches the bottom, water injection begins. At the same time, the vibration device starts to vibrate to eliminate the bubbles in the water injection device. After the vibration device stops, open the air valve 18 in the water injection device, and the inside and outside The air is connected, and the water in the water injection mechanism begins to penetrate into the electronic material board under the action of gravity. When the liquid level in the measuring cylinder 15 drops by 50 milliliters, start timing and record the initial scale. Thereafter, record the scale every one minute until it drops by 200 milliliters. If the liquid level drops too slowly, only the three-minute liquid level scale is measured. If the liquid level drops quickly and drops by 200 milliliters within three minutes, record the time when it drops by 200 milliliters. If it stops after dropping to a certain extent, it means that it is basically or completely waterproof, and it should be recorded in the report.

[0030] like Figure 1 and Figure 2As shown, the water injection mechanism includes a water injection cylinder 9, a sealing ring is arranged at the bottom of the water injection cylinder 9, sliding sleeves 10 are fixedly installed on both sides of the water injection cylinder 9, the sliding sleeves 10 are slidably connected with the sliding column 4, a hinge seat 11 is arranged at the top of the water injection cylinder 9, a water injection cavity 12 is arranged inside the water injection cylinder 9, the top of the water injection cavity 12 is arranged in a funnel shape, an exhaust pipe 13 and a water inlet pipe 14 are opened on one side of the water injection cylinder 9, the exhaust pipe 13 is connected to the top of the water injection cavity 12, and the water inlet pipe 14 is connected to the inner wall of the water injection cavity 12. A press valve 16 is installed at the interface of the water inlet pipe 14. The press valve 16 is a press-type valve. The press switch has a release rebound effect. A measuring cylinder 15 is fixedly installed on the top of the mounting plate 2. The measuring cylinder 15 is a transparent cylinder with a scale. A sealing cover 17 is installed on the top of the measuring cylinder 15. An air valve 18 is installed on the top of the sealing cover 17. The top of one side of the measuring cylinder 15 is connected to the exhaust pipe 13 through a transparent hose, and the bottom of one side of the measuring cylinder 15 is connected to the input port of the press valve 16 through a transparent hose.

[0031] When the water injection mechanism is pressed onto the electronic material board, the water injection cylinder 9 and the electronic material board are tightly fitted under the action of the sealing ring, and the pressing valve 16 contacts the upper surface of the mounting plate 2 and becomes open. The water in the measuring cylinder 15 slowly begins to rise from the water inlet pipe 14 at the bottom of the water injection chamber 12 under the action of gravity, and discharges the gas inside the water injection chamber 12 into the measuring cylinder 15 through the exhaust pipe 13 until the liquid level inside the transparent hose is level with the liquid level in the measuring cylinder 15. At this time, since the air valve 18 is closed, the inside of the water injection mechanism is not connected with the outside world. Under the action of atmospheric pressure, water will not penetrate into the electronic material board. After opening the air valve 18, the inside of the water injection mechanism is connected with the outside atmosphere. Under the action of gravity, water begins to penetrate downward through the electronic material board. Compared with the prior art, the space for gas accumulation is reduced. At the same time, the pressing mechanism is linked, so that water injection and exhaust are automatically performed when the water injection mechanism touches the bottom, which is more convenient. In addition, water is injected from bottom to top, which reduces bubbles generated by the impact of water flow and air during water injection.

[0032] like Figure 1 and Figure 2 As shown, the clamping mechanism includes a pressing arm 6 hinged to both sides of the first column 3, a horizontal column 7 is arranged in the middle of the pressing arm 6, a connecting rod 8 is hinged on the horizontal column 7, one end of the connecting rod 8 is hinged to the hinge seat 11, and an extension seat 26 is fixedly installed on one side of the first column 3, the extension seat 26 is L-shaped, and a tension spring 27 is hinged at the extension end of the extension seat 26, and the other end of the tension spring 27 is hinged to the middle part of one side of the pressing arm 6;

[0033] Under the action of the extending seat 26 and the tension spring 27, the clamping mechanism has two stable states, one at the highest point and the other at the lowest point. When pressed downward, the tension spring 27 pulls the pressure arm 6 to provide downward pressure to press the water injection cylinder 9 onto the electronic material board. When lifted upward, the tension spring 27 pulls the pressure arm 6 to provide upward pressure to stabilize the water injection cylinder 9 at the highest point. Compared with the prior art, the operation is simpler and more convenient during use, saving time and effort.

[0034] like Figure 1 and Figure 3 As shown, the vibration mechanism includes a second column 19 fixed on the top of the mounting plate 2, a knocking wheel 24 is rotatably mounted on one side of the second column 19, a torsion spring is installed between the knocking wheel 24 and the second column 19, a pulley 21 and a winding roller 23 are rotatably mounted on the other side of the second column 19, the winding roller 23 is fixedly connected to the axis of the knocking wheel 24, the pulley 21 is located at the bottom of one side of the second column 19, a tying column 22 is fixedly installed on one side of the sliding sleeve 10, a pull rope is wound around the winding roller 23, and the pull rope is wound around The bottom of the pulley 21 is fixed on the bolt column 22, and a vibration cylinder 20 is fixedly installed on the top of the mounting plate 2. The vibration cylinder 20 includes a stainless steel cylinder and a spring fixed at the bottom of the stainless steel cylinder. The vibration cylinder 20 contacts the knocking wheel 24. A ring array of hammers 25 is arranged on the outer side wall of the knocking wheel 24. The hammers 25 are hinged to the knocking wheel 24. A torsion spring is arranged between the knocking wheel 24 and the hammers 25. The movable angle of the hammers 25 is zero to sixty degrees. In the initial state, the hammers 25 are in an open state.

[0035] When the water injection mechanism reaches the stable state at the highest point upward, the tie column 22 pulls the pull rope, and the pull rope rotates to store energy for the torsion spring inside the knocking wheel 24. When the water injection mechanism reaches the stable state at the lowest point downward, the torsion spring of the knocking wheel 24 begins to release elastic potential energy, causing the knocking wheel 24 to rotate. Since the knocking wheel 24 is provided with a hammer 25, and the hammer 25 is provided with a torsion spring, when storing energy, the hammer 25 is folded inward under the squeezing of the vibration tube 20, so as to facilitate the rotation and energy storage of the knocking wheel 24. When releasing, the knocking wheel 24 rotates in the opposite direction, and the hammer 25 opens outward to push the vibration tube 20 outward. At this time, there is resistance, and the release of elastic potential energy is relatively slow. When the water injection mechanism reaches the lowest end and starts to inject water, the knocking wheel 24 is still rotating, and the knocking wheel 24 generates vibration by hitting the vibration tube 20 to remove the bubbles in the water. Compared with the prior art, the removal of bubbles is more sufficient, so that the influence of bubbles on the experiment is smaller.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
