Description

Technical Field

[0001] This utility model relates to the field of continuity detection technology, and in particular to an LED light continuity detection device. Background Technology

[0002] Currently, commercially available light-emitting diode (LED) lights typically employ conformal coatings and nano-coatings for protection, shielding the LEDs and their circuit boards from environmental corrosion and improving their reliability and lifespan. Using nano-coating technology for LED protection not only provides superior protection but also allows for a thinner surface finish.

[0003] Because nano-coating insulates components, while LED leads need to be conductive, a shielding fixture is typically used to block the LED leads during nano-coating to prevent the coating from affecting their conductivity. After nano-coating, the LED's conductivity is quickly checked manually. Currently, two test pens (or probes) are usually used to light the LED, and the continuity of the LED leads is determined by the lighting status. However, this method of continuity testing is inconvenient, hinders production operations, and has low efficiency. Utility Model Content

[0027] As mentioned above, since nano-coating insulates components, and LED leads need to be conductive, to avoid the nano-coating affecting the LED lead conductivity, a shielding fixture is typically used to block the LED leads during nano-coating to assist in the process. After nano-coating, the LED's conductivity is quickly and manually checked. Currently, two test pens are usually used to light up the LEDs, and the continuity of the LED leads is determined by the lighting status. However, this method of aligning and contacting the test pens with the LED leads and testing each LED individually is inconvenient, hinders production operations, and results in low continuity testing efficiency.

[0028] To address the aforementioned issues, this application provides an LED continuity testing device comprising a mounting section and a support assembly. The mounting section holds at least one LED. The support assembly includes two support portions located on opposite sides of the mounting section and movable toward or away from it. Each support portion is equipped with at least one probe, which moves with the support portion to contact or disconnect from the corresponding LED pin. Thus, by moving the two support portions, contact and disconnection between the probe and the LED pin can be achieved, eliminating the need for manual probe-pin alignment, improving operational convenience, facilitating online testing, simplifying production operations, and enabling simultaneous continuity testing of multiple LEDs, thereby increasing LED continuity testing efficiency.

[0029] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] This application provides an LED light continuity detection device for detecting whether an LED light is conducting. The following is in conjunction with... Figures 1 to 5 The specific structure of the LED light continuity detection device is described in detail.

[0031] In a specific implementation, the LED continuity detection device 100 includes a mounting part 20 and a carrier assembly 30. The mounting part 20 is used to mount LED lights 200, and the mounting part 20 is used to place at least one LED light 200, wherein the LED light 200 has pins 201. The carrier assembly 30 includes two carrier parts 301, which are respectively located on both sides of the mounting part 20 and can move toward or away from the mounting part 20. Each carrier part 301 is provided with at least one probe 40, and the probe 40 moves with the carrier part 301 to contact or disconnect from the pin 201 of the corresponding LED light 200.

[0032] As can be seen from the above, when performing continuity testing on LED lamp 200, LED lamp 200 is placed on mounting part 20, and the contact and disconnection between probe 40 and pin 201 of LED lamp 200 can be achieved by moving the two support parts 301. There is no need for manual alignment of probe 40 and pin 201, which improves the convenience of operation, facilitates online testing, and is convenient for production operations. In addition, mounting part 20 is used to place at least one LED lamp 200, so multiple LED lamps 200 can be tested for continuity at the same time, improving the efficiency of LED lamp 200 continuity testing.

[0033] In some embodiments, the mounting portion 20 is provided with a plurality of placement slots, and each placement slot holds an LED light 200. The schematic diagram provided in this application illustrates an example where the mounting portion 20 holds one LED light and each support portion 301 is provided with a probe 40.

[0034] In some non-limiting embodiments, when multiple LED lights 200 are placed on the mounting part 20, multiple probes 40 are provided on each corresponding support part 301. Two probes 40 at corresponding positions on two support parts 301 form a probe pair. The number of probe pairs is greater than or equal to the number of LED lights 200 that can be placed on the mounting part 20. This will not be illustrated here by way of schematic diagram.

[0035] In some other non-limiting embodiments, when multiple LEDs 200 are placed on the mounting portion 20, each carrier portion 301 may be provided with a probe component, which can contact the pins 201 of the multiple LEDs 200. The specific structure and size of the probe component are not limited here; they can be configured according to actual needs.

[0036] In some embodiments, the probe 40 is larger than the pin 201 of the LED 200. Thus, even if the placement of the LED 200 is slightly off or the pin positions of different LED models are slightly different, the probe 40 can still contact the pin 201, improving the probe 40's tolerance to deviations in the LED 200's placement and its compatibility with different LED models.

[0037] In some other embodiments, the probe 40 is smaller than the pin 201 of the LED 200. The probe size can be adapted to the pin size and placement of the LED to facilitate contact between the probe 40 and the pin 201.

[0038] In some embodiments, each carrier portion 301 may be a single unit.

[0039] In other embodiments, each carrier portion 301 may be separate, and each separate carrier portion 301 may include multiple sub-carrier portions. Each sub-carrier portion may be provided with a probe 40. The number of probes 40 provided on each sub-carrier portion may be the same or different. The multiple sub-carrier portions may move synchronously or independently, depending on the specific requirements.

[0040] In some embodiments, the support assembly 30 further includes a slide rail 302. The two support portions 301 are slidably disposed on the slide rail 302.

[0041] In some embodiments, each support portion 301 includes a support plate 31 and a slider assembly 33. The support plate 31 is used to mount the probe 40; the slider assembly 33 is connected to the support plate 31 and slidably connected to the slide rail 302.

[0042] In some non-limiting embodiments, the carrier plate 31 is a metal plate and is conductive. The two carrier plates 31 are connected to the positive and negative terminals, respectively. Thus, the carrier plate 31 connected to the positive terminal provides a positive voltage to the probe 40 on that carrier plate 31, and the carrier plate 31 connected to the negative terminal provides a negative voltage to the probe 40 on that carrier plate 31. When both probes 40 on both carrier plates 31 are in contact with the pin 201 of the LED lamp 200, the continuity detection circuit can be turned on to perform continuity detection. It is understood that the probes 40 can also be configured to be connected to either the positive or negative terminal; specifically, the probe 40 on one carrier plate 31 can be connected to the positive terminal, and the probe 40 on the other carrier plate 31 can be connected to the negative terminal.

[0043] Furthermore, the positive and negative terminals connected to the two carrier plates 31 can be switched. If the LED 200 is not placed correctly, the pins 201 of the LED 200 may be connected to the wrong positive and negative terminals, leading to false detections. By switching the positive and negative terminals connected to the two carrier plates 31, continuity testing of the LED 200 can be completed without adjusting its placement, avoiding false detections caused by incorrect placement and improving the accuracy of continuity testing.

[0044] In some embodiments, the probe 40 is disposed on the end face 312 of the support plate 31 facing the mounting portion 20 and protrudes from the end face 312.

[0045] In some non-limiting embodiments, the support plate 31 is integrally formed with the probe 40. For example, a plurality of ribs or teeth are formed on the end face 312 of the support plate 31 facing the mounting portion 20, and the plurality of ribs or teeth serve as the probe 40.

[0046] In some other non-limiting embodiments, the support plate 31 is disposed relatively independently from the probe 40, and the probe 40 is connected to the support plate 31. The support plate 31 is provided with a mounting structure for mounting the probe 40. For example, the support plate 31 is provided with a mounting hole into which the probe 40 is inserted.

[0047] In some embodiments, the support plate 31 is provided with a grip portion 311. For example, the grip portion 311 may be an elongated strip structure extending along the main body of the support portion 301. The specific construction of the grip portion 311 may be ergonomic to improve the user's grip comfort.

[0048] In some embodiments, the LED light continuity detection device 100 further includes an anti-slip portion disposed on the grip portion 311. The anti-slip portion may be an anti-slip protrusion or anti-slip texture disposed on the grip portion 311, or it may be an anti-slip sleeve with anti-slip function fitted onto the grip portion 311.

[0049] In some non-limiting embodiments, the slider assembly 33 includes a first slider 331 and a second slider 332. The first slider 331 is slidably connected to the slide rail 302; the second slider 332 is located between the first slider 331 and the support plate 31, and is fixedly connected to the support plate 31 and the first slider 331. For example, the first slider 331, the second slider 332, and the support plate 31 can be fixedly connected by fasteners such as screws.

[0050] In some non-limiting embodiments, the slide rail 302 has a groove on its side, and the first slider 331 has a protrusion that matches the groove, the protrusion sliding within the groove. The cooperation between the groove and the protrusion guides the sliding direction of the first slider 331, ensuring the smooth movement of the support portion 301 relative to the mounting portion 20, thereby improving the accuracy of the contact position between the probe 40 and the LED lamp pin.

[0051] In some non-limiting embodiments, the bottom surface of the second slider 332 is provided with a receiving groove 3321, wherein the first slider 331 is fixedly connected to the receiving groove 3321.

[0052] The directions in which the support portion 301 moves toward and away from the mounting portion 20 are denoted as direction x, and the slide rail 302 extends along direction x. The slider assembly 33 slides along the slide rail 302 in direction x.

[0053] In some embodiments, the LED light continuity detection device 100 further includes a positioning component 50. The positioning component 50 includes a positioning hole 51 and a positioning post 52. The positioning hole 51 is disposed in one of the support plate 31 and the second slider 332, and the positioning post 52 is disposed in the other of the support plate 31 and the second slider 332.

[0054] In some non-limiting embodiments, the number of positioning holes 51 is the same as the number of positioning posts 52. To improve positioning accuracy, the number of positioning holes 51 and positioning posts 52 can be multiple. The accompanying drawings provided in this application illustrate an example where the support plate 31 has two positioning holes 51 and the second slider 332 has two positioning posts 52. It should be noted that the number of positioning holes 51 and positioning posts 52 is not limited to two; it can also be one or more.

[0055] It should be noted that the shape of the positioning hole 51 is adapted to the shape of the positioning post 52. The positioning hole 51 can be a circular hole, and the external shape of the positioning post 52 can be cylindrical. It is understood that the shapes of the positioning hole 51 and the positioning post 52 are not limited to these, and can also be polygonal or other suitable shapes.

[0056] In some embodiments, the LED light continuity detection device 100 further includes a base plate 10. The base plate 10 is used to support the mounting part 20 and the support assembly 30, and the support part 301 is movable relative to the base plate 10.

[0057] In some embodiments, the mounting part 20 is detachably connected to the base plate 10. This allows for the selection of a mounting part 20 of the appropriate model based on the type of LED lamp 200 to be tested, improving compatibility for LED lamp type detection.

[0058] In some non-limiting embodiments, the base plate 10 may be provided with a first mounting groove 11 for placing the mounting part 20. The surface of the first mounting groove 11 is lower than the plane of the base plate 10. The first mounting groove 11 facilitates the installation and positioning of the mounting part 20, improving the ease of assembly and assembly accuracy of the mounting part 20. For example, the mounting part 20 can be fixedly connected to the base plate 10 by fasteners such as screws. Alternatively, the mounting part 20 can be detachably connected to the base plate 10 by components such as clips.

[0059] In some non-limiting embodiments, the base plate 10 may be provided with a second mounting groove 12 for placing the slide rail 302. The surface of the second mounting groove 12 is lower than the plane of the base plate 10. The second mounting groove 12 facilitates the installation and positioning of the slide rail 302, improving the ease of assembly and assembly accuracy of the slide rail 302. For example, the slide rail 302 can be fixedly connected to the base plate 10 by fasteners such as screws.

[0060] The mounting part 20 is positioned above the slide rail 302, and the mounting part 20 is provided with a clearance opening 21 for avoiding the slide rail 203. The first mounting groove 11 and the second mounting groove 12 may have an intersection area to avoid interference between the mounting part 20 and the slide rail 302. The bottoms of the first mounting groove 11 and the second mounting groove 12 are flush.

[0061] In some embodiments, the LED light continuity detection device 100 further includes a limiting component 90. The limiting component 90 is disposed on the base plate 10 and is used to limit the maximum distance between the support portion 301 and the mounting portion 20.

[0062] In some non-limiting embodiments, the limiting component 90 includes a plurality of limiting posts 91. The plurality of limiting posts 91 are divided into a first group and a second group, with the limiting posts 91 of the first group and the limiting posts 91 of the second group located on both sides of the two support portions 301, respectively. Each of the first and second groups includes one or more limiting posts 91. The accompanying drawings of this application illustrate four limiting posts 91 as an example, with each support portion 301 corresponding to two limiting posts 91, and the two limiting posts 91 located on both sides of the slide rail 302. In practice, the number of limiting posts 91 is not limited to this and can be configured according to the specific dimensions of the support portion 301.

[0063] In some embodiments, the LED continuity detection device 100 further includes an elastic reset member 70, which is disposed at least one of the mounting portion 20 and the slider assembly 33, and is located between the mounting portion 20 and the slider assembly 33. The elastic reset member 70 is configured to be in a compressed state when the probe 40 contacts the pin 201 of the LED 200.

[0064] In some embodiments, the mounting portion 20 is provided with a receiving cavity 80 for accommodating a portion of the elastic reset member 70. Further, a portion of the elastic reset member 70 may be fixedly connected within the receiving cavity 80.

[0065] In other embodiments, the slider assembly 33 is provided with a receiving cavity 80 for receiving a portion of the elastic reset member 70. Furthermore, a portion of the elastic reset member 70 may be fixedly connected within the receiving cavity 80.

[0066] In some other embodiments, the mounting portion 20 is provided with a receiving cavity 80, the slider assembly 33 is provided with a receiving cavity 80, one end of the elastic reset member 70 is located in the receiving cavity 80 on the mounting portion 20, and the other end of the elastic reset member 70 is located in the receiving cavity 80 on the slider assembly 33. When the distance between the bearing portion 301 and the mounting portion 20 is at its maximum, the probe 40 does not contact the pin 201 of the LED lamp 200, and the elastic reset member 70 is in a free state or a compressed state.

[0067] In some embodiments, elastic reset members 70 are provided on both sides of the mounting portion 20 to push the corresponding bearing portion 301.

[0068] When the probe 40 contacts the pin 201 of the LED lamp 200, the elastic reset member 70 is in a compressed state and stores compressed energy. After the continuity test of the LED lamp 200 is completed, under the action of compressed energy, the elastic reset member 70 can drive the bearing part 301 to move away from the mounting part 20, thereby releasing the contact between the probe 40 and the pin 201 of the LED lamp 200, so as to remove the LED lamp 200.

[0069] In some embodiments, the elastic reset member 70 may be a spring, elastic rubber, or other elastic components.

[0070] To facilitate a better understanding of this application by those skilled in the art, the following description is provided in conjunction with... Figure 3 and Figure 4 The specific working principle of this application will be explained. Figure 3 and Figure 4 The arrow in the figure indicates the direction of movement of the support unit 301.

[0071] Figure 3 The diagram shows the LED lamp continuity detection device in its initial state, with the probe 40 and the carrier 301 moving away from the mounting part 20. The LED lamp 200 is placed into the mounting part 20. The two carrier parts 301 are moved towards the mounting part 20, for example, by pinching the gripping part 311 on the carrier plate 31 with two fingers, causing the two gripping parts 311 to move towards each other. At this time, the probes 40 on the two carrier parts 301 move towards the mounting part 20 until the probes 40 contact the pins 201 of the LED lamp 200. If the LED lamp 200 is lit, the pins 201 are conductive; conversely, if the LED lamp 200 is not lit, the pins 201 are not conductive. After completing the continuity detection of the LED lamp 200, the two gripping parts 311 are released. At this time, the elastic reset member 70 pushes the carrier part 301 away from the mounting part 20 (i.e., the opposite direction of the arrow in the diagram), releasing the contact between the probes 40 and the pins 201 of the LED lamp 200. The LED lamp 200 is then removed. Continue by adding other LEDs (200) and repeating the above steps to perform a continuity test.

[0072] In the embodiments of this application, "multiple" refers to two or more.

[0073] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
