[0043] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0044] See Figure 1 , Figure 1Schematic diagram of the structure of a product applicable to an embodiment of the present utility model. Specifically, the product 200 includes a workpiece 210, a fitting 220 provided on one side of the workpiece 210, and electronic components (not shown) installed on the side of the workpiece 210 away from the fitting 220. Among them, the workpiece 210 can be a middle frame, the fitting 220 can be a mobile phone screen, the fitting 220 is embedded in the front of the workpiece 210, and the space between the fitting 220 and the workpiece 210 is filled with sealant. For the product 200 with qualified water tightness, water will flow through the fitting 220 and the workpiece 210 in turn, and flow out from the edge of the workpiece 210, and will not overflow from the connection between the fitting 220 and the workpiece 210 to the back of the workpiece 210. The electronic components installed on the back of the workpiece 210 will not come into contact with water, effectively avoiding damage to the electronic components.

[0045] See Figures 2 to 4 The embodiment of the present invention provides a testing fixture 100 for testing the water tightness of a product 200 , including a supporting seat 110 , a sealing member 120 , a cover assembly 130 and a locking assembly 140 . The bearing seat 110 is provided with a bearing surface 110a and a hollow groove 110b, and the hollow groove 110b passes through the bearing surface 110a. The sealing member 120 is provided on the bearing surface 110a and is arranged around the hollow groove 110b. The bearing surface 110a is used to support the product 200 so that the product 200 covers the hollow groove 110b and abuts against the inner wall of the sealing member 120. The cover assembly 130 includes a cover seat 131, a water inlet member 132 and a water outlet member 133. The cover seat 131 is detachably connected to the bearing seat 110 and is provided with a water injection groove 131a. The water inlet member 132 and the water outlet member 133 are both provided on the cover seat 131 and are respectively connected to the water injection groove 131a. The locking assembly 140 is connected to the bearing seat 110 and is used to press the cover seat 131 to the bearing seat 110 so that the sealing member 120 abuts between the bearing seat 110 and the cover seat 131. When the cover seat 131 is connected to the support seat 110, the water injection groove 131a is connected to the hollow groove 110b, and the sealing member 120 is arranged around the water injection groove 131a. Exemplarily, the sealing member 120 is a sealing rubber ring.

[0046] In this embodiment, the water injection groove 131a and the hollow groove 110b are coaxially arranged. When the inspection fixture 100 is performing inspection operations, the workpiece 210 with the fitting 220 is placed on the supporting surface 110a and the top of the hollow groove 110b is covered. After water is injected into the water injection groove 131a, the back of the workpiece 210 can be observed through the bottom of the hollow groove 110b.

[0047] See Figure 3 and Figure 4In some embodiments, the water inlet member 132 includes a water inlet pipe 1321 and a water inlet switch 1322. The water inlet pipe 1321 is disposed on the cover seat 131 and connected to the water filling tank 131a, and is used to introduce water into the water filling tank 131a. The water inlet switch 1322 is installed on the water inlet pipe 1321 and is used to control the opening and closing of the water inlet pipe 1321. The water outlet member 133 includes a water outlet pipe 1331 and a water outlet switch 1332. The water outlet pipe 1331 is disposed on the cover seat 131 and connected to the water filling tank 131a, and is used to discharge water from the water filling tank 131a. The water outlet switch 1332 is installed on the water outlet pipe 1331 and is used to control the opening and closing of the water outlet pipe 1331. For example, both the water inlet switch 1322 and the water outlet switch 1332 may be electronic valves.

[0048] Therefore, the inflow and outflow of water in the water tank 131a can be conveniently controlled by the water inlet switch 1322 and the water outlet switch 1332. In addition, the water flow rate in or out of the water tank 131a can be adjusted as needed, so that the water level in the water tank 131a can quickly and stably reach the desired level, thereby achieving precise control of the water flow in the water tank 131a and optimizing the use efficiency of the water tank 131a.

[0049] See Figure 3 In some embodiments, the depth of the water injection groove 131a gradually increases from the periphery of the water injection groove 131a to the middle of the water injection groove 131a. Specifically, the top of the water injection groove 131a is arc-shaped.

[0050] Therefore, through the above arrangement, the water injection groove 131a is easy to drain and the pressure on the sealing member 120 located at the end of the water injection groove 131a can be reduced.

[0051] In this embodiment, the water inlet pipe 1321 and the water outlet pipe 1331 are both connected to the middle portion of the cover base 131 and spaced apart. Therefore, this arrangement facilitates the separate assembly and disassembly of the water inlet pipe 1321 and the water outlet pipe 1331, and also adapts to the curved structure at the top of the water filling trough 131a, thereby improving the water filling and drainage efficiency within the water filling trough 131a.

[0052] See Figures 3 to 5 In some embodiments, the support base 110 includes a fixing member 111 and a supporting member 112. The fixing member 111 defines a fixing hole 111a, which passes through the fixing member 111. The supporting member 112 is disposed on the fixing member 111 and is detachably connected to the fixing member 111. The supporting member 112 defines a bearing hole 112a. The bearing surface 110a is disposed on a side of the supporting member 112 facing away from the fixing member 111. The bearing hole 112a passes through the bearing surface 110a and communicates with the fixing hole 111a to form a hollow groove 110b.

[0053] In this embodiment, the fixing member 111 is detachably connected to the bearing member 112 via a plurality of bolts.

[0054] Therefore, the fixing member 111 and the supporting member 112 are detachably connected, which makes it easy to replace the fixing member 111 , so that the supporting base 110 is adapted to a variety of different products 200 , thereby improving the applicability of the supporting base 110 .

[0055] In some embodiments, the cover seat 131 includes a cover member 1311 , a mounting member 1312 , a water stop member 1313 and a locking member 1314 . The cover member 1311 defines a cover hole 1311a that passes through the cover member 1311. The mounting member 1312 defines a receiving groove 1312a on a side facing the cover member 1311. The cover hole 1311a and the receiving groove 1312a communicate with each other to form the water inlet groove 131a. The water inlet member 132 and the water outlet member 133 are both disposed on the mounting member 1312 and communicate with the receiving groove 1312a, respectively. A water stop member 1313 is abutted between the cover member 1311 and the mounting member 1312 and is disposed around the cover hole 1311a. A locking member 1314 is disposed through the cover member 1311 and the mounting member 1312 and is threadedly connected to the support base 110 to secure the support base 110 to the cover base 131. Exemplarily, the water stop member 1313 is a sealing rubber ring.

[0056] In this embodiment, the locking member 1314 is composed of a plurality of bolts.

[0057] See Figure 3 and Figure 4 In some embodiments, at least one of the side of the cover member 1311 facing the mounting member 1312 and the side of the mounting member 1312 facing the cover member 1311 is provided with a positioning groove 131b, and the water stop member 1313 is accommodated in the positioning groove 131b.

[0058] Therefore, the positioning groove 131b can limit the water stop member 1313 in the horizontal direction, preventing the water stop member 1313 from shaking between the cover member 1311 and the mounting member 1312, which is beneficial to improving the water sealing performance of the water filling groove 131a.

[0059] In this embodiment, the positioning groove 131b is only provided on the side of the cover member 1311 facing the mounting member 1312. In other embodiments, the positioning groove 131b may be provided only on the side of the mounting member 1312 facing the cover member 1311, or the positioning groove 131b may be provided on both the side of the cover member 1311 facing the mounting member 1312 and the side of the mounting member 1312 facing the cover member 1311.

[0060] See Figure 4 and Figure 5In some embodiments, at least one of the carrying surface 110 a and the side of the cover seat 131 facing the carrying surface 110 a is provided with a receiving groove 100 a , and the sealing member 120 is received in the receiving groove 100 a .

[0061] Therefore, the accommodating groove 100a can limit the sealing member 120 in the horizontal direction, preventing the sealing member 120 from shaking between the supporting surface 110a and the cover seat 131, which is beneficial to improving the water tightness of the sealing member 120 between the supporting surface 110a and the cover seat 131.

[0062] In this embodiment, the receiving groove 100a is only provided on the side of the cover member 1311 of the cover seat 131 facing the carrying surface 110a. In other embodiments, the receiving groove 100a may be provided only on the carrying surface 110a, or the receiving groove 100a may be provided on both the carrying surface 110a and the side of the cover member 1311 facing the carrying surface 110a.

[0063] See Figure 3 In some embodiments, the cover seat 131 defines a groove 131c, and the locking assembly 140 includes a rotating member 141 and a locking member 142. One end of the rotating member 141 is rotatably connected to the support seat 110, and one end of the locking member 142 is rotatably connected to the other end of the rotating member 141 and defines a pressing arc surface 142a. The pressing arc surface 142a is adapted to the groove 131c to form a groove locking structure.

[0064] In this embodiment, there are two sets of locking components 140 , and the two sets of locking components 140 are respectively located at two opposite ends of the supporting base 110 .

[0065] See Figure 3 and Figure 4 In some embodiments, the detection fixture 100 further includes a protective member 150. The protective member 150 is connected to the side of the support base 110 away from the support surface 110a and covers the hollow groove 110b, and the protective member 150 is a light-transmitting structure.

[0066] Therefore, the protective member 150 can shield the hollow groove 110b of the support base 110, preventing external components from entering the hollow groove 110b, thereby improving the safety of the product 200 located on the support surface 110a. In addition, the light-transmitting protective member 150 facilitates observation of water leaks.

[0067] In this embodiment, the protective member 150 is substantially in the shape of a plate and is detachably connected to the fixing member 111 of the supporting base 110 by bolts.

[0068] See Figure 6The present invention also provides a detection device 1000, comprising a water supply fixture 300, a pressure-boosting fixture 400, and the detection fixture 100 of the above embodiment. The water supply fixture 300 is used to store water and connect to the water tank 131a through the water inlet 132 and the water outlet 133. The pressure-boosting fixture 400 is used to connect to the water tank 131a and increase the pressure in the water tank 131a after storing the target amount of water in the water tank 131a. The water inlet switch 1322 and the water outlet switch 1332 provided above facilitate the control of the pressure applied to the water tank 131a and also facilitate the pressure maintenance operation in the water tank 131a during the water tightness test.

[0069] It should be noted that the water supply fixture 300 is detachably connected to the water inlet 132 and the water outlet 133. It is connected when filling or draining water and disconnected when inspecting the watertightness of the product 200. The pressurizing fixture 400 can increase the pressure in the water tank 131a after water is injected and maintain it for a preset period of time based on testing needs, thereby improving the efficiency and accuracy of watertightness testing.

[0070] Furthermore, if a more accurate confirmation of the leakage path is required, fluorescent liquid or ink can be added to the water so that after the product 200 is separated from the detection fixture 100, the water leakage trajectory can be confirmed based on the color path, thereby further improving the accuracy of watertightness detection.

[0071] The working process of the above detection device 1000 is roughly as follows:

[0072] First, the workpiece 210 with the fitting 220 is placed on the carrying surface 110 a so that the peripheral side of the workpiece 210 abuts against the inner wall of the sealing member 120 ;

[0073] Next, fix the supporting base 110 and the cover base 131 so that the connection between the fitting 220 and the workpiece 210 is placed in the water injection groove 131a.

[0074] Then, water is injected into the water injection tank 131a through the water inlet 132 by the water supply fixture 300, so that the water completely covers the connection between the bonding member 220 and the workpiece 210 and reaches a preset amount;

[0075] Then, the pressure in the water injection tank 131a is increased to a preset value and maintained for a preset time by the booster fixture 400;

[0076] Finally, observe through the protective member 150 whether there is a water leak on the side of the workpiece 210 away from the bonding member 220. If there is a water leak, it indicates that the water tightness of the product 200 is unqualified. If not, it indicates that the water tightness of the product 200 is qualified.

[0077] It should be noted that when placing the product 200, assembling the detection jig 100 and filling the water filling tank 131a with water, the protective part 150 can be located at the bottom and the cover seat 131 can be located at the top. When pressurizing the water filling tank 131a and observing whether there are any leaks, the detection jig 100 can be flipped over so that the protective part 150 is located at the top and the cover seat 131 is located at the bottom, so as to facilitate observation and confirmation through the protective part 150, and at the same time, it is more conducive to the drainage operation of the water filling tank 131a after the water tightness test is completed.

[0078] Therefore, during the inspection process, the inspection fixture 100 in the inspection device 1000 of the above embodiment, because the side of the adhesive 220 facing away from the workpiece 210 is in contact with water, the electronic components located on the workpiece 210 facing away from the adhesive 220 are not exposed to water, effectively preventing damage to the electronic components during the inspection process. Furthermore, the inspection device 1000 of the above embodiment is simple to operate, simplifying the watertightness testing method, thereby improving the efficiency of the inspection device 1000 in watertightness testing. Furthermore, the simple structure and low manufacturing cost of the inspection device 1000 of the above embodiment reduce the cost of watertightness testing of the inspection device 1000.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be encompassed within the present invention.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
