Description

Technical Field

[0001] This utility model relates to the field of automated testing technology for electronic components, specifically a synchronous testing mechanism for the electrical continuity of LED lamp circuit boards. Background Technology

[0002] LED lights have become the mainstream product in the lighting industry due to their advantages such as high efficiency, energy saving, long lifespan, and environmental friendliness. The core component of an LED light is the circuit board (PCB), which carries the LED chip and driver components. The quality of its electrical conductivity directly determines the functional integrity, luminous quality, and lifespan of the LED light.

[0003] Currently, the industry commonly uses testing mechanisms with multiple test probes to test the electrical continuity of LED light circuit boards. These probes form a circuit by contacting preset test points on the circuit board, thus determining the continuity of the circuit. However, existing testing mechanisms suffer from significant positioning difficulties in practical applications, limiting testing efficiency and accuracy. Utility Model Content

[0004] This invention provides a synchronous testing mechanism for the electrical continuity of LED lamp circuit boards, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A synchronous testing mechanism for the electrical continuity of an LED lamp circuit board includes a housing, a base plate on the top of the housing, a probe in the middle of the base plate, an LED circuit board placed above the probe, a support plate for fixing the LED circuit board on the outer side of the base plate, a pressure plate on the top of the housing, and a pressure plate post that cooperates with the LED circuit board below the pressure plate.

[0007] As a preferred embodiment of this utility model, positioning posts that cooperate with the tray are provided at the four corners of the substrate, and tray support posts that cooperate with the tray are provided on both sides of the substrate.

[0008] As a preferred embodiment of this utility model, the side of the housing is provided with a DB54 interface and a DB40 interface.

[0009] The present invention has the following advantages:

[0010] 1. Three-level linkage mechanism of "pressure plate-support plate-probe": The pressure plate drives the support plate assembly to move precisely, and the probe below makes contact. This avoids the potential damage to the components on the circuit board surface caused by direct pressure in the traditional method, resulting in more stable contact and longer life.

[0011] 2. Integrated anti-misinsertion design: The DB54 and DB40 interfaces are used as electrical signal input ports, realizing hardware-level reverse connection protection, which improves operational safety and reliability.

[0012] 3. Combination of elastic support and rigid guidance: The support column of the tray provides buffering and reset functions, while the positioning column ensures no offset during the entire pressing process, guaranteeing the alignment accuracy of the probe and the circuit board pad during each test.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In one embodiment, see Figures 1-4A synchronous testing mechanism for the electrical continuity of an LED lamp circuit board includes a housing 10, a base plate 5 on the top of the housing 10, a probe 4 in the middle of the base plate 5, the probe 4 being elastic and retractable, an LED circuit board placed on top of the probe 4, a support plate 3 for fixing the LED circuit board on the outer side of the base plate 5, thereby fixing the LED circuit board in place by the support plate 3, a pressure plate 1 on the top of the housing 10, and a pressure plate post 2 cooperating with the LED circuit board below the pressure plate 1.

[0021] In one embodiment, positioning posts 6 that cooperate with the tray 3 are provided at the four corners of the substrate 5 to prevent the tray 3 from shifting. Tray support posts 7 that cooperate with the tray 3 are provided on both sides of the substrate 5. The tray support posts 7 have an elastic and retractable effect.

[0022] In one embodiment, the side of the housing 10 is provided with a DB54 interface 8 and a DB40 interface 9. The DB54 interface 8 is for connecting a positive electrical signal to a positive probe 4, and the DB40 interface 9 is for connecting a negative electrical signal to a negative probe 4. The positive electrical signal is input through one DB54 interface 8, and the negative electrical signal is input through one DB40 interface 9. The DB54 interface 8 and DB40 interface 9 are completely different in physical structure, number of pins, and definition, forming a physical foolproof mechanism. This fundamentally eliminates the problem of reversed power supply polarity or incorrect interface insertion due to operator error, protecting the safety of the circuit board under test and the testing equipment.

[0023] The implementation process of this embodiment is as follows:

[0024] Initial state: The LED circuit board to be tested is placed in a dedicated tray 3. The tray 3 is supported by tray support columns 7, which have built-in elastic elements such as springs to provide initial support force and allow the tray 3 to make precise elastic displacement in the vertical direction.

[0025] The pressing process: The operator presses down the operating handle, which moves the pressure plate 1 and the pressure plate column 2 on it downward together.

[0026] Circuit board positioning and downward movement: The pressure plate and pressure column 2 first contact and press down on the LED circuit board, and then drive the entire LED circuit board and support plate 3 to overcome the elasticity of the support column of support plate 3 and move downward smoothly.

[0027] Precision guidance: During this process, the positioning pins 6 are precisely inserted into the corresponding holes at the four corners of the support plate 3, effectively preventing any displacement of the support plate 3 in the horizontal direction and ensuring the coaxiality and stability of the pressing process.

[0028] Electrical contact and lighting: When the tray 3 assembly moves down to the predetermined stroke, the test probe 4 fixed on the substrate 5 passes through the preset avoidance hole on the tray 3 from below, and accurately contacts the positive and negative pads on the back of the LED circuit board to form a circuit and light up the LED beads.

[0029] Data acquisition: Parameters such as on-resistance are detected in the electrical signal circuit.

[0030] Reset: Release the handle, and under the elastic force of the support column of the tray 3, the tray 3 will automatically reset to the initial position and wait for the next test.

[0031] This utility model applies to a synchronous testing mechanism for the electrical continuity of LED lamp circuit boards. The support plate 3 provides buffering and reset functions, while the positioning column 6 ensures no offset during the entire pressing process, guaranteeing the alignment accuracy of the probe 4 with the circuit board pads during each test.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
