[0041] A method for testing an LED filament, the method comprising the following steps:
[0042] Step 1: Product placement: Place the product to be tested between the two diagonal support shell plates 5, with both ends of the product to be tested located under the N-shaped detection guide block 7;
[0043] Step 2: Product electrical parameter test: The product electrical parameter test is to move the push plate 4 upward under the push of the electric telescopic rod 3, and use the conductive arc plate 9 in the N-type detection guide block 7 to contact the product. In this way, the product parameters will be displayed on the LED parameter tester 8, and the product electrical parameter test is completed;
[0044] Step 3: Product mechanical strength test. After step 2, the electric telescopic rod 3 will continue to push the product upward, and use the clamping force of the induction clamp 1203 to fix the product. In the process of the electric telescopic rod 3 driving the push plate 4 to move upward, the L-shaped opening 1310 will be used to engage with the spring 1309. In this way, when the electric telescopic rod 3 is retracted, it will drive the movable guide block 1306 to move downward. In the process of the movable guide block 1306 moving downward, the bending block 1302 will be driven to rotate through the connecting rod 1305, thereby pulling the connecting rod 1305. The tension sensor 1204 on the L-shaped connecting rod 1205 in the frame 1304 moves in the opposite direction, which can apply an opposite tension to the product on the sensing clamp 1203, thereby achieving the mechanical strength test. In the process of the electric telescopic rod 3 moving downward, the extrusion block 1311 will squeeze the spring 1309, causing the spring 1309 to pop out. In this way, under the rotation action of the return spring 1303, the bending block 1302 can be reset. After that, the operator removes the product for observation to observe the degree of damage on the product surface, and the product mechanical strength test is completed.
[0045] The working principle of the above embodiment is:
[0046] When using the device, the product to be tested needs to be placed between the two diagonal support shells 5, with both ends of the product to be tested located under the N-shaped detection guide block 7. In this way, the test effect of the product can be guaranteed under the push of the electric telescopic rod 3;
[0047] Under the push of the electric telescopic rod 3, the push plate 4 moves upward, and the conductive arc plate 9 in the N-type detection guide block 7 is used to contact the product. The conductive arc plate 9 is connected to the conductive wire 701. This can ensure the power-on effect of the conductive arc plate 9 and the normal test effect of the LED parameter tester 8. The product parameters will be displayed on the LED parameter tester 8, which can ensure the electrical parameter test effect of the product.
[0048] As the electric telescopic rod 3 continues to push the product upward, the product is fixed by the clamping effect of the sensing clamp 1203, and the electric telescopic rod 3 drives the pushing plate 4 to move upward, the L-shaped opening 1310 is used to engage with the spring piece 1309. In this way, after the electric telescopic rod 3 pushes the product to be tested upward to the position of the sensing clamp 1203, the recovery process will drive the moving guide block 1306 to move downward. In the process of moving the moving guide block 1306 moving downward, the bending block 1302 is driven to rotate through the connecting rod 1305, thereby pulling the tension sensor 1204 on the L-shaped connecting rod 1205 inside the connecting frame 1304 to move in the opposite direction, thereby applying tension to the product on the sensing clamp 1203, thereby achieving the mechanical strength test effect, and when the electric telescopic rod 3 moves upward During the downward movement, the squeezing block 1311 will contact the L-shaped opening 1310 in the pushing plate 4, so that the squeezing block 1311 will squeeze the spring 1309, and the spring 1309 will fall off the L-shaped opening 1310 under the elastic push of the squeezing block 1311, thereby releasing the limiting effect on the moving guide block 1306, so that the rotation of the rotary spring 1303 is utilized to release the tension output of the product to be tested, and then the operator dismantles and observes to observe the degree of damage to the product to be tested, thereby completing the test of the mechanical strength of the product. The device highlights the innovative structure and does not elaborate too much on the existing mature technologies. For example, the LED parameter tester 8, the tension sensor 1204, the tension data display screen 1003, etc. are all mature technologies, and this device will not be elaborated too much.
[0049] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.

A method for testing LED filaments, characterized in that: An LED filament testing device according to any one of claims 1 to 9, wherein the LED filament testing method comprises the following steps: Step 1: product placement, wherein the product to be tested is placed in two diagonal support shell plates (5), with both ends of the product to be tested located at the lower side of the N-shaped detection guide block (7); Step 2: Product electrical parameter test. The product electrical parameter test is performed by moving the push plate (4) upward under the push of the electric telescopic rod (3), and using the conductive arc plate (9) in the N-type detection guide block (7) to contact the product. In this way, the product parameters will be displayed on the LED parameter tester (8), thereby completing the product electrical parameter test. Step 3: Product mechanical strength test. The product mechanical strength test is as follows: after step 2, the electric telescopic rod (3) will continue to push the product upward, and the product will be fixed by the clamping force of the induction clamp (1203). In the process of the electric telescopic rod (3) driving the push plate (4) to move upward, the L-shaped opening (1310) will be used to engage with the spring (1309). In this way, when the electric telescopic rod (3) is retracted, the moving guide block (1306) will be driven to move downward. In the process of the moving guide block (1306) moving downward, the bending block (1302) will be driven to rotate through the connecting rod (1305), thereby pulling the product. The tension sensor (1204) on the L-shaped connecting rod (1205) in the connecting frame (1304) moves in the opposite direction, so that the product on the sensing clamp (1203) can be subjected to an opposite tension, thereby achieving a mechanical strength test. In the process of the electric telescopic rod (3) moving downward, the extrusion block (1311) will squeeze the spring (1309), causing the spring (1309) to pop out. In this way, the bending block (1302) can be reset under the rotation of the rotation spring (1303). After that, the operator removes the product for observation to observe the degree of damage on the product surface, thus completing the product mechanical strength test.
