Description

Technical Field

[0001] The invention relates to the technical field of waterproof testing of linear lights, and in particular to a pressurized linear light waterproof testing device. Background Art

[0002] Linear lights, also known as LED light strips (or light strips), refer to LEDs assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board. They are named because their shape resembles a strip. They are gradually emerging in various decoration industries because of their long service life (normal life is generally 80,000 to 100,000 hours), energy saving and environmental protection. Among them, flexible linear lights use FPC as the assembly circuit board and high-brightness LEDs with SMD packages (SMD) as the light source. Because the FPC material used is soft, it can be bent, folded and wound at will. In addition, the flexible LED light strips are potted with silicone to achieve a waterproof effect.

[0003] Flexible linear lights need to be tested for waterproofing after production. The traditional testing method is to pass the linear lights through a water tank and then observe whether the linear lights go out. If they do not go out, it means that the waterproofing performance of the linear lights is qualified. However, when facing longer linear lights, the traditional testing method will face greater challenges.

[0004] Since the water in the water tank will adhere to the surface of the line light, it will bring out some of the water in the water tank during the movement of the line light, causing the water level in the water tank to drop. Once the water level drops, the contact area between the line light and the water will be reduced, causing most of the line light to be unable to contact the water, thus affecting the efficiency of the test. Summary of the invention

[0005] The object of the present invention is to provide a booster type linear light waterproof testing device to solve the problems raised in the above background technology.

[0012] The first piston assembly further includes a first infusion tube having one end connected to the interior of the first piston tube and the other end connected to the spray assembly, and a second one-way valve disposed in the first infusion tube, the second one-way valve being used to prevent the liquid in the first infusion tube from flowing into the first piston tube;

[0013] The first infusion tube is made of flexible material.

[0014] As a further improvement of the technical solution, the spray assembly includes a drain pipe and a rotating wheel;

[0015] The drainage pipe is a three-way structure with one end connected to the first infusion pipe and the other two ends rotatably connected to the rotating wheel;

[0016] The rotating wheel is used to discharge the liquid in the drain pipe and rotates through the liquid;

[0017] It also includes a slider fixedly arranged on the side wall of the drain pipe and a slide rail fixedly arranged on the inner wall of the water tank. The slider is slidably connected to the slide rail. The slide rail is set to be parallel to the line light to keep the route of the rotating wheel corresponding to the line light.

[0018] As a further improvement of the present technical solution, the drain pipe is in an "F"-shaped structure, the bottom end of the drain pipe is a water inlet end for connecting to the first infusion pipe, and the other two ends are water outlet ends for connecting to the rotating wheel.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the booster type linear light waterproof test equipment, the piston plate moves up and down to drive the spray assembly to move along the surface of the linear light, so that the unsoaked part and the part not in contact with water are continuously impacted by water flow, so that liquid continues to exist on the surface of the linear light, thereby simulating an immersed environment. In addition, the up and down movement of the piston plate can change the internal pressure of the water tank, and accelerate the liquid on the surface of the unsoaked part and the part not in contact with water to enter the interior of the linear light by means of high pressure, thereby completing the test of the unsoaked part and the part not in contact with water of the linear light, so as to improve the efficiency of the test.

[0030] 2. In the pressurized linear light waterproof test equipment, the rotating wheels located above and below the linear light can also squeeze the linear light during movement.

[0031] 3. In the pressurized linear light waterproof test equipment, the rotating wheel near the exit can not only move on the surface of the linear light, but also drive the linear light in a reverse manner, so that the tested part of the linear light is automatically moved out of the water tank, realizing automatic position change of the linear light and reducing manual operation.

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 creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0045] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0046] The state of the line light 200 penetrating into the water tank 100 is as follows Figure 2 As shown, the line light 200 enters from the inlet 101, and then passes through the pressure roller 103 and exits from the outlet 102. The part of the line light 200 in the water tank 100 is the part that needs to be tested. After the test of this part is completed, the line light 200 is pulled so that the rest of the line light 200 enters the water tank 100 through the inlet 101, and then the test continues. However, when the line light 200 leaves the water tank 100, it will bring out the water in the part, causing the water level in the line light 200 to drop.

[0047] When the water level drops, the state of the line light 200 is as follows: Figure 2 As shown, the line lights 200 near the outlet 102 are the un-immersed parts 202, the line lights 200 near the pressure roller 103 are the immersed parts 201, and the line lights 200 near the inlet 101 are the parts not in contact with water 203. In this way, although the un-immersed parts 202 pass through the liquid during the movement, the waterproof test needs to be maintained for a certain period of time, during which time, the moisture on the surface of the un-immersed parts 202 will fall off, which makes it impossible to perform the waterproof test on the un-immersed parts 202 and the parts not in contact with water 203, so that only the immersed parts 201 can be tested each time, thereby affecting the efficiency of the test.

[0048] To this end, the present invention provides a pressurized linear light waterproof testing device, please refer to Figure 1 and Figure 2 As shown, it includes a water tank 100 having an inlet 101 and an outlet 102, and a piston plate 110 arranged inside the water tank 100; wherein, the top of the water tank 100 is provided with an opening, and liquid is stored inside, and the heights of the inlet 101 and the outlet 102 are both higher than the height of the liquid level, so as to prevent the liquid from flowing out through the inlet 101 and the outlet 102. In addition, the inlet 101 and the outlet 102 are arranged opposite to each other, so that the line light 200 can pass through the inlet 101 into the water tank 100, and then pass through the outlet 102. The piston plate 110 changes the space inside the water tank 100 by sliding, so that the internal pressure of the water tank 100 can be higher than the external pressure.

[0049] A first piston assembly 120 and a spray assembly 130 are also provided inside the water tank 100. The first piston assembly 120 pressurizes the liquid at the bottom of the water tank 100 into the spray assembly 130 during the sliding of the piston plate 110. The spray assembly 130 has a spray port 134 and a movement path consistent with the shape of the line light 200. By delivering the liquid into the spray assembly 130, the spray assembly 130 uses the force of the liquid to move along the movement path, and sprays the liquid on the parts of the line light 200 that are not in contact with the liquid through the spray port 134.

[0050] The first piston assembly 120 and the spray assembly 130 are both located at opposite ends of the water tank 100 .

[0051] It should be understood that the piston plate 110 mentioned above changes the space in the water tank 100 by sliding, so that the internal pressure of the water tank 100 can be higher than the external pressure. Figure 2 In the embodiment shown, the first cylinder 111 is fixedly arranged on the top of the water tank 100, and the movable end of the first cylinder 111 is fixedly connected to the piston plate 110, and the outer ring of the piston plate 110 is slidably fitted with the inner wall of the water tank 100. In this way, when the first cylinder 111 drives the piston plate 110 to move downward, the space between the piston plate 110 and the bottom of the water tank 100 begins to decrease, and the air inside the water tank 100 is compressed, so that the internal pressure of the water tank 100 is higher than the external pressure. In addition, a pressure relief valve (not shown in the figure) can also be provided on the side wall of the water tank 100, and the pressure relief valve can prevent the phenomenon of excessive internal pressure of the water tank 100 caused by the long downward movement of the piston plate 110.

[0052] It should be noted that, during the downward movement of the piston plate 110 , the inlet 101 and the outlet 102 should be in a sealed state to prevent the gas inside the water tank 100 from being discharged through the inlet 101 and the outlet 102 . Figure 3 The embodiment shown shows a sealable structure of the inlet 101 and the outlet 102. As shown in the figure, the sealable structure includes a support plate (not numbered in the figure) located below the inlet 101 and the outlet 102, and a rubber block 104 located above the line light 200 (the rubber material can prevent the line light 200 from being pinched); wherein, the support plate is fixedly arranged on the side wall of the water tank 100, the rubber block 104 is a "U"-shaped structure with the opening facing downward, and the side wall of the rubber block 104 is slidably fitted with the side wall of the water tank 100, and the top of the rubber block 104 is connected to a second cylinder 105 fixed to the side wall of the water tank 100. The rubber block 104 is driven downward by the second cylinder 105, so that the rubber block 104 squeezes the line light 200 onto the support plate, and the side wall of the rubber block 104 seals the inlet 101 and the outlet 102, thereby preventing the gas inside the water tank 100 from being discharged through the inlet 101 and the outlet 102.

[0053] like Figure 4 As shown, the first piston assembly 120 includes a first piston tube 121 fixedly arranged on the inner wall of the bottom of the water tank 100, the bottom end of the first piston tube 121 is sealed by the inner wall of the bottom of the water tank 100, the outer wall of the bottom of the first piston tube 121 is provided with a liquid inlet 122, and a first one-way valve 123 is provided inside to prevent the liquid in the first piston tube 121 from being discharged through the liquid inlet 122. A first piston rod 124 is longitudinally slidably arranged on the inner wall of the first piston tube 121, and the first piston rod 124 is an inverted "T" shaped structure, the outer ring of the bottom end is slidably fitted with the inner wall of the first piston tube 121, and the top end extends to the bottom of the piston plate 110. At the same time, a return spring 125 is provided between the bottom end of the first piston rod 124 and the side wall of the first piston tube 121 to elastically connect the two. The first piston assembly 120 further includes a first liquid infusion tube 126, one end of which is connected to the interior of the first piston tube 121 and the other end of which is connected to the spray assembly 130, and a second one-way valve 127 disposed in the first liquid infusion tube 126, the second one-way valve 127 being used to prevent the liquid in the first liquid infusion tube 126 from flowing into the first piston tube 121. The first liquid infusion tube 126 is made of a flexible material to avoid affecting the movement of the drain pipe 131.

[0054] It should be noted that the structure of the first one-way valve 123 belongs to the prior art and will not be elaborated herein in the present invention.

[0055] like Figure 5 As shown, the spray assembly 130 includes a drain pipe 131 and a rotating wheel 133. The drain pipe 131 is a three-way structure with one end connected to the first infusion pipe 126 and the other two ends rotatably connected to the rotating wheel 133. The rotating wheel 133 is used to discharge the liquid in the drain pipe 131 and rotate through the liquid. The spray assembly 130 also includes a slider 136 fixedly arranged on the side wall of the drain pipe 131, and a slide rail 138 fixedly arranged on the inner wall of the water tank 100. The slider 136 is slidably connected to the slide rail 138. The slide rail 138 is set to be parallel to the line light 200, so as to keep the route of the rotating wheel 133 corresponding to the line light 200.

[0056] It should be understood that the slide rail 138 is parallel to the linear light 200 , which means that the spray assembly 130 can move along the linear light 200 via the slide rail 138 , that is, the movement route consistent with the shape of the linear light 200 mentioned above.

[0057] Furthermore, the drain pipe 131 is in an “F”-shaped structure, the bottom end of the drain pipe 131 is a water inlet end for connecting to the first liquid infusion pipe 126 , and the other two ends are water outlet ends 132 for rotatably connecting to the rotating wheel 133 .

[0058] The rotating wheels 133 are arranged above and below the linear light 200 in an opposing manner, and the distance between the two rotating wheels 133 is consistent with the thickness of the linear light 200. The interior of the rotating wheel 133 is a hollow structure, and an opening is arranged on one side. The rotating wheel 133 is rotatably connected to the water outlet 132 through the opening arranged on one side. The outer ring of the rotating wheel 133 is provided with a plurality of spraying ports 134 connected to the interior, and a spiral impeller 135 with one end penetrating into the water outlet 132 is fixedly arranged inside the rotating wheel 133, and the spiral direction of the spiral impeller 135 is set according to the actual position.

[0059] In addition, in order to increase the friction between the rotating wheel 133 and the linear light 200, the portion of the drain pipe 131 between the two water outlet ends 132 is a retractable structure, and a connecting spring 137 is provided between the two water outlet ends 132, one end of the connecting spring 137 is connected to the top water outlet end 132, and the other end is connected to the bottom water outlet end 132. The elasticity of the connecting spring 137 causes the drain pipe 131 to contract, thereby driving the two rotating wheels 133 to approach each other and clamp the linear light 200.

[0060] That is, the piston plate 110 is moved up and down to drive the spray assembly 130 to move along the surface of the line light 200, so that the un-immersed portion 202 and the portion 203 of the line light 200 that are not in contact with water are continuously impacted by water flow, so that liquid continues to exist on the surface of the line light 200, thereby simulating an immersed environment. In addition, the up and down movement of the piston plate 110 can change the internal pressure of the water tank 100, and accelerate the liquid on the surface of the un-immersed portion 202 and the portion 203 that are not in contact with water to enter the interior of the line light 200 by means of high pressure, thereby completing the test of the un-immersed portion 202 and the portion 203 of the line light 200 that are not in contact with water, so as to improve the efficiency of the test.

[0061] Moreover, the rotating wheels 133 located above and below the linear light 200 can also squeeze the linear light 200 during movement, and use the squeezing force to determine the strength of the connection between the internal structures of the linear light 200, and cooperate with the impact force when spraying the liquid to impact the squeezed parts, thereby improving the accuracy of the test of the linear light 200 and avoiding some potential problems of the linear light 200.

[0062] Working principle:

[0063] The line light 200 is inserted into the inlet 101, passes through the pressure roller 103, and then passes out of the outlet 102. Then the second cylinder 105 is controlled to drive the rubber block 104 downward, so that the inlet 101 and the outlet 102 are sealed. At this time, a closed chamber is formed between the bottom of the piston plate 110 and the water tank 100. Then the first cylinder 111 drives the piston plate 110 downward, and the downward movement of the piston plate 110 causes the space in the water tank 100 to become smaller, so that the air pressure in the water tank 100 increases, and the pressurization detection of the line light 200 is realized.

[0064] During the downward movement of the piston plate 110, the piston plate 110 pushes the first piston rod 124 downward, and the first piston rod 124 moves downward to squeeze the liquid in the first piston tube 121 into the drain pipe 131 through the second one-way valve 127 and the first liquid infusion tube 126, and then discharges into the rotating wheel 133 through the water outlet 132, and then discharges through the spray port 134. During the flow of the liquid in the water outlet 132, the liquid drives the rotating wheel 133 to rotate through the spiral impeller 135, and the rotating wheel 133 rotates on the surface of the linear light 200 through friction, and the moving direction is referenced Figure 6 In the direction indicated by the arrow in the middle, the liquid is discharged to the surface of the line light 200 through the spray port 134, thereby moistening the part of the line light 200 that is not in contact with water. When the wheel 133 moves to the top of the slide rail 138, the wheel 133 cannot continue to rotate, and the water discharged through the spray port 134 will flow on the surface of the line light 200, and the line light 200 is in a "V" shape. The water will flow from the high point of the line light 200 to the low point, so that there is continuous moisture on the surface of the line light 200.

[0065] When the piston plate 110 moves upward, the pressure inside the water tank 100 begins to recover. At this time, the first piston rod 124 moves upward and resets through the reset spring 125, and during the reset process, the liquid at the bottom of the water tank 100 is pumped into the first piston tube 121 through the liquid inlet 122 and the first one-way valve 123. Then the second cylinder 105 is controlled to drive the rubber block 104 to move upward, so that the inlet 101 and the outlet 102 are opened. Finally, the line light 200 is pulled to make the line light 200 originally located inside the water tank 100 detach from the water tank 100, and the line light 200 originally located outside the water tank 100 enters the water tank 100, and the other parts of the line light 200 are tested through the above steps.

[0066] refer to Figure 6When the rotating wheel 133 rotates to the top of the slide rail 138, the rotating wheel 133 needs to be reset. Therefore, the slide rail 138 is set to an inclined state in the present invention. Correspondingly, the line light 200 also needs to be in an inclined state. For this reason, the present invention also rotatably sets a pressure roller 103 located above the line light 200 inside the water tank 100. By setting the pressure roller 103 near the bottom of the line light 200, the pressure roller 103 presses down the middle of the line light 200. At this time, the line light 200 forms a "V" shape structure, and the inclined slide rail 138 is parallel to the line light 200. In this way, when the rotating wheel 133 rotates to the top of the slide rail 138, the weight of the rotating wheel 133 and the components such as the drain pipe 131 slides downward, thereby realizing the reset of the rotating wheel 133. In addition, the pressure roller 103 pressing down the line light 200 can also ensure that at least a part of the line light 200 can contact the liquid in the water tank 100.

[0067] In other embodiments, the position of the line light 200 in the water tank 100 is automatically changed, such as Figure 7-Figure 9 As shown, the test equipment also includes a second piston assembly 140 arranged in the water tank 100, the second piston assembly 140 is arranged at one end of the water tank 100 close to the outlet 102, the first piston assembly 120 is arranged at one end of the water tank 100 close to the inlet 101, and the spray assembly 130 is arranged at both ends of the water tank 100 in an opposing manner.

[0068] The second piston assembly 140 includes a second piston tube 141 fixedly arranged on the inner wall of the bottom of the water tank 100, the bottom end of the second piston tube 141 is sealed by the inner wall of the bottom of the water tank 100, a second piston rod 142 is longitudinally slidably arranged inside the second piston tube 141, and a support spring 143 is arranged between the bottom of the second piston rod 142 and the side wall of the second piston tube 141 to elastically connect the two. The side wall of the second piston tube 141 is connected to a second infusion tube 144, and one end of the second infusion tube 144 is connected to the drainage tube 131 close to the second piston tube 141.

[0069] The side wall of the water outlet end 132 near the second piston tube 141 is connected to a water inlet 150, and a third one-way valve 151 is provided in the water inlet 150 for preventing the liquid in the water outlet end 132 from being discharged through the water inlet 150. The end of the water inlet 150 is connected to an extension tube 152 with one end extending to the inner wall of the bottom of the water tank 100, which can prevent the water inlet 150 from sucking in air.

[0070] Working principle:

[0071] When the piston plate 110 moves upward and resets, the rotating wheel 133 resets to the bottom end of the slide rail 138 by gravity. At the same time, the support spring 143 rebounds and drives the second piston rod 142 to move upward and reset. The second piston rod 142 moves upward and resets, which generates suction inside the second piston tube 141, so that the liquid at the bottom of the water tank 100 is sucked into the second piston tube 141 through the extension tube 152, the third one-way valve 151, the water inlet 150, the water outlet 132, the drain pipe 131, and the second liquid infusion tube 144. When the liquid passes through the water outlet 132, the liquid will push the spiral impeller 135. Since the liquid flows into the water outlet 132, the liquid will push the spiral impeller 135 to rotate toward the pressure roller 103. For details, refer to Fig. 9 When the rubber block 104 is separated from the inlet 101, since the two ends of the line light 200 are no longer restricted, and the rotating wheel 133 is at the bottom of the slide rail 138 and cannot move toward the pressure roller 103, the rotating wheel 133 can drive the line light 200 toward the outlet 102, so that the line light 200 located outside enters the water tank 100 through the inlet 101.

[0072] Furthermore, during this process, due to the difference in structure, the rotating wheel 133 near the inlet 101 will not rotate automatically, thereby not affecting the rotating wheel 133 near the outlet 102 .

[0073] In summary, the rotating wheel 133 near the outlet 102 can not only move on the surface of the linear light 200, but also drive the linear light 200 in a reverse manner, so that the tested part of the linear light 200 is automatically moved out of the water tank 100, thereby realizing automatic position change of the linear light 200 and reducing manual operation.
