Description

Technical Field

[0001] This utility model belongs to the field of neon light technology, specifically relating to a neon light aging test device. Background Technology

[0002] Neon lights use flexible PVC or silicone shells to encase LED beads to simulate neon effects. Before leaving the factory, the LED strip beads need to undergo quality control, one of which is aging test. The LED strip is laid flat on an anti-static table, connected to a regulated power supply, and continuously powered on for 2-48 hours. This continuous power supply stimulates early faults, and the LED strip is visually inspected to check for problems such as short circuits, open circuits, and poor contact.

[0003] In existing technologies, some long neon light strips (such as 10-100 meters) occupy a lot of space when laid flat on the testing table. Especially when batch testing is carried out, multiple testing tables need to be carried out in parallel, resulting in a high space occupancy rate. Quality inspectors need to patrol back and forth for inspection. In addition, the brightness of the light source of the light strip fluctuates periodically with the current. The high-frequency flicker is invisible to the naked eye but may cause headaches and dry eyes. Long-term continuous staring at the light source of the light strip, the uneven distribution of light intensity may also cause eye fatigue or damage. Utility Model Content

[0004] The purpose of this invention is to provide a neon light aging test device that can place neon light strips in a ring-shaped test groove. Compared with traditional test benches, it greatly saves space. Quality inspectors do not need to move around to check the quality of the light strips inside by rotating the ring-shaped test groove. Furthermore, the isolation and filtering by the protective lens can reduce the damage or fatigue to the eyes caused by unstable flickering and uneven light intensity of the light strips.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A neon light aging test device includes an annular testing groove rotatably mounted on the top of a support platform. The top of the annular testing groove has an open notch, and an inner circular plate is fixedly connected to its center. Above the annular testing groove is a connecting plate that slides axially. The outer wall of the connecting plate is fixedly provided with a three-layer composite protective lens, which consists of a light-transmitting base layer, an anti-flicker coating layer, and a microlens layer in sequence.

[0007] The annular detection groove is rotatably connected to the support platform via a bearing assembly.

[0008] The height of the inner circular plate is lower than the groove opening plane of the annular detection groove.

[0009] A multi-stage electric cylinder is fixedly assembled at the top center of the support platform, and its output end is fixedly connected to the connecting plate. A through hole is opened at the center of the inner circular plate for the multi-stage electric cylinder to pass through.

[0010] The inner side of the connecting plate has several heat dissipation holes arranged in an array, and the upper part of the protective lens is provided with an openable protective cover.

[0011] The outer wall of the annular detection groove is uniformly provided with anti-slip texture.

[0012] The outer wall of the inner circular plate is symmetrically fixed with an electrical connector, and a conductive slip ring is electrically assembled on the top of the support platform and on the outside of the multi-stage electric cylinder.

[0013] The inner ring of the conductive slip ring is fixedly connected to the inner circular plate, and its top is symmetrically electrically connected with wires. The wires pass through the interior of the inner circular plate and are electrically connected to the power connector.

[0014] The technical advantages of this invention are as follows: neon light strips can be placed in a ring-shaped inspection slot, which greatly saves space compared to traditional inspection stations. Quality inspectors do not need to move around to check the quality of the light strips inside by rotating the ring-shaped inspection slot. Furthermore, the isolation and filtering by the protective lens can reduce the damage or fatigue to the eyes caused by unstable flickering and uneven light intensity of the light strips.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-3As shown, a neon light aging test device includes an annular detection groove 1 rotatably mounted on the top of a support platform 102. The annular detection groove 1 is rotatably connected to the support platform 102 via a bearing assembly 101. The top of the annular detection groove 1 has an open notch, and an inner circular plate 103 is fixedly connected to its center. A connecting plate 105 that slides axially is provided above the annular detection groove 1. A three-layer composite protective lens 106 is fixedly installed on the outer wall of the connecting plate 105. The protective lens 106 is composed of a light-transmitting base layer, an anti-flicker coating layer, and a microlens layer in sequence. A multi-stage electric cylinder 104 is fixedly assembled at the top center of the support platform 102, and its output end is fixedly connected to the connecting plate 105. An openable protective cover 108 is provided above the protective lens 106. Electrical connectors 109 are symmetrically fixedly assembled on the outer wall of the inner circular plate 103.

[0022] According to the above structure, when not in use, the protective cover 108 is placed on top of the protective lens 106 for protection, to prevent impurities from falling and damaging the protective lens 106 and to prevent dust from accumulating. When in use, the protective cover 108 is lifted, and the output end of the multi-stage electric cylinder 104 is extended by the electric control switch located on the side wall of the support platform 102, which lifts up the connecting plate 105 and the protective lens 106 away from the annular detection groove 1. The light strip is placed in a circular manner inside the annular detection groove 1, that is, between the side wall of the annular detection groove 1 and the inner circular plate 103. The light strip is connected to the power connector 109 to make it emit light.

[0023] Furthermore, pressing the switch again controls the output end of the multi-stage electric cylinder 104 to retract, and the connecting plate 105 and the protective lens 106 descend to cover the top of the annular detection groove 1. However, there is still a small gap between the protective lens 106 and the annular detection groove 1, and they are not completely fitted. The protective lens 106 has a three-layer structure that is laminated layer by layer, including the bottom PMMA substrate, which provides a transparent and rigid support structure that allows light to pass through. The thickness is 1-3MM. The middle layer is an anti-flicker coating with a light transmittance of ≥85%. It forms a functional layer through optical coating technology to selectively filter low-frequency flicker light and reduce the flicker perceived by the human eye, but it does not significantly change the static optical characteristics of the light strip (such as brightness and color temperature).

[0024] Furthermore, the top layer of PDMS material microlens layer has a light transmittance of ≥92%. The surface is covered with a large number of micron-level light-transmitting apertures and embossed depths to disperse the light evenly and avoid localized over-brightness that could damage the eyes, without changing the overall light-emitting logic of the light strip (e.g., a damaged single LED will still result in a dark area). The bearing assembly 101 is connected to the support platform 102 via the inner ring and to the annular detection groove 1 via the outer ring. The quality inspector can sit on one side of the support platform 102 and manually rotate the annular detection groove 1. The light strip and the inner circular plate 103 will rotate accordingly, and the eyes can observe and inspect the light strip below through the protective lens 106.

[0025] See attached document Figures 1-3The height of the inner circular plate 103 is lower than the groove plane of the annular detection groove 1. The center of the inner circular plate 103 is provided with a through hole for the multi-stage electric cylinder 104 to pass through. The inner side of the connecting plate 105 is provided with a number of heat dissipation holes 107 arranged in an array. The outer wall of the annular detection groove 1 is uniformly provided with anti-slip texture 110. The top of the support platform 102 and the outer side of the multi-stage electric cylinder 104 are electrically assembled with a conductive slip ring 111. The inner ring of the conductive slip ring 111 is fixedly connected to the inner circular plate 103, and its top is symmetrically electrically connected with wires 112. The wires 112 pass through the inside of the inner circular plate 103 and are electrically connected to the power connector 109.

[0026] According to the above structure, when the protective lens 106 is lowered and placed on the top of the annular detection groove 1, since the height of the inner circular plate 103 is lower than the groove opening plane of the annular detection groove 1, the height difference can be set to 3-10CM as needed. Therefore, the connecting plate 105 will not be in contact with the inner circular plate 103. The heat generated by the light strip inside the annular detection groove 1 is dissipated outward through this gap via the heat dissipation hole 107. The anti-slip texture 110 can increase the friction between the annular detection groove 1 and the hand when rotating it, preventing slippage.

[0027] Furthermore, the support platform 102 provides power to the multi-stage electric cylinder 104 and the conductive slip ring 111. The conductive slip ring 111 provides power to the power connector 109 and the light strip through the wire 112. The conductive slip ring 111 is a common double-ring hollow cylindrical structure. It mainly achieves 360-degree rotation to conduct electricity or transmit signals through the contact between the brush bristles and the ring body. The outer ring stator connected to the support platform 102 is fixed, while the inner ring rotor connected to the inner circular plate 103 rotates together with the inner circular plate 103, ensuring that the wire 112 and the power connector 109 can rotate with the light strip and the inner circular plate 103, preventing the wire 112 from getting tangled and broken.

[0028] This invention allows neon light strips to be placed in a circular inspection groove 1, which greatly saves space compared to traditional inspection tables. Quality inspectors can inspect the quality of the light strips inside by rotating the circular inspection groove 1 without having to move around. Furthermore, the isolation and filtering by the protective lens 106 can reduce the damage or fatigue to the eyes caused by unstable flickering and uneven light intensity of the light strips.

[0029] The working principle of this utility model is as follows: When stored at rest, the protective cover 108 is placed on top of the protective lens 106 to protect it from impurities falling and damaging the protective lens 106 and to prevent dust accumulation. When in use, the protective cover 108 is lifted, and the output end of the multi-stage electric cylinder 104 is extended by the electric control switch located on the side wall of the support platform 102, which lifts up the connecting plate 105 and the protective lens 106 away from the annular detection groove 1. The light strip is placed in a circular manner inside the annular detection groove 1, that is, between the side wall of the annular detection groove 1 and the inner circular plate 103. The light strip is connected to the power connector 109 to make it emit light.

[0030] Furthermore, pressing the switch again controls the output end of the multi-stage electric cylinder 104 to retract, and the connecting plate 105 and the protective lens 106 descend to cover the top of the annular detection groove 1. However, there is still a small gap between the protective lens 106 and the annular detection groove 1, and they are not completely fitted. The protective lens 106 has a three-layer structure that is laminated layer by layer, including the bottom PMMA substrate, which provides a transparent and rigid support structure that allows light to pass through. The thickness is 1-3MM. The middle layer is an anti-flicker coating with a light transmittance of ≥85%. It forms a functional layer through optical coating technology to selectively filter low-frequency flicker light and reduce the flicker perceived by the human eye, but it does not significantly change the static optical characteristics of the light strip (such as brightness and color temperature).

[0031] Furthermore, the top layer of PDMS material microlens layer has a light transmittance of ≥92% and a large number of raised curved surfaces with micron-level light-transmitting apertures and relief depths to evenly disperse the light and avoid local over-brightness that could damage the eyes, without changing the overall light-emitting logic of the light strip (e.g., if a single LED bead is damaged, it will still appear as a dark area). The bearing assembly 101 is connected to the support platform 102 through the inner ring and to the annular detection groove 1 through the outer ring. The quality inspector can sit on one side of the support platform 102 and manually rotate the annular detection groove 1. The light strip and the inner circular plate 103 will rotate accordingly, and the eyes can observe and inspect the light strip below through the protective lens 106.

[0032] Furthermore, when the protective lens 106 is lowered and placed on top of the annular detection groove 1, since the height of the inner circular plate 103 is lower than the groove opening plane of the annular detection groove 1, the height difference can be set to 3-10CM as needed. Therefore, the connecting plate 105 will not be in contact with the inner circular plate 103. The heat generated by the light strip inside the annular detection groove 1 is dissipated outward through this gap via the heat dissipation hole 107. The anti-slip texture 110 can increase the friction between the annular detection groove 1 and the hand when rotating it, preventing slippage.

[0033] Furthermore, the support platform 102 provides power to the multi-stage electric cylinder 104 and the conductive slip ring 111. The conductive slip ring 111 provides power to the power connector 109 and the light strip through the wire 112. The conductive slip ring 111 is a common double-ring hollow cylindrical structure. It mainly achieves 360-degree rotation to conduct electricity or transmit signals through the contact between the brush bristles and the ring body. The outer ring stator connected to the support platform 102 is fixed, while the inner ring rotor connected to the inner circular plate 103 rotates together with the inner circular plate 103, ensuring that the wire 112 and the power connector 109 can rotate with the light strip and the inner circular plate 103, preventing the wire 112 from getting tangled and broken.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
