Description

Technical Field

[0001] The utility model relates to the technical field of light strip production, in particular to a wheel-type light strip testing device. Background Art

[0002] LED light strips are widely used because they can be curled into any desired shape to create a variety of rich patterns. The light source of LED light strips is composed of LED lamp beads installed on a strip circuit board to form an LED light strip light source. In order to ensure product quality, the LED light strip light source needs to be tested during the production process to detect whether each lamp bead is normally lit when powered on. At present, the common lighting method in the industry is to contact the exposed test points of the circuit layer with a probe to form a contact circuit power-on test or an alligator clip contact test point test. However, when using this mode of testing, the product needs to be fixed and aligned. During the test, the product needs to be in a relatively static state without moving back and forth. Each test requires the FPC to stop moving before it is performed, which limits the flexible use of the test single process in the process flow. At the same time, each test requires the probe to perform actions such as pressing down and docking, resulting in low overall testing efficiency of the light strip. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In the present application, the support frame 5 includes a top plate 501, a first partition plate 502 and a second partition plate 503. The first partition plate 502 and the second partition plate 503 have the same structure. The first partition plate 502 and the second partition plate 503 are symmetrically installed at left and right intervals below the top plate 501 and above the material feeding mechanism 10. The conductive wheel 6 is rotatably connected between the first partition plate 502 and the second partition plate 503 through a rotating shaft 9. The left and right ends of the rotating shaft 9 are rotatably installed with the first partition plate 502 and the second partition plate 503 respectively.

[0020] In the present application, the conductive wheel 6 includes a support ring 603, a first copper ring 601 and a second copper ring 602, the first copper ring 601 and the second copper ring 602 are mounted on the left and right ends of the outer side of the support ring 603, the support ring 603, the first copper ring 601 and the second copper ring 602 are coaxially installed, the support ring 603 is made of non-conductive material, the rotating shaft 9 passes through the support ring 603 and is coaxially installed and fixed with the support ring 603, an isolation ring 604 made of non-conductive material is provided between the first copper ring 601 and the second copper ring 602, in this embodiment, the isolation ring 604 and the support ring 603 are both made of silicone material, a first conductive brush 7 is installed between the first copper ring 601 and the first partition 502 for contacting the first copper ring 601 to form a positive current, a second conductive brush 8 is provided between the second copper ring 602 and the second partition 503 for contacting the second copper ring 602 to form a negative current, and the first conductive brush 7 and the second conductive brush 8 have the same structure.

[0021] The first conductive brush 7 includes a first copper sheet 701 and a first copper block 702 installed at one end of the first copper sheet 701. The other end of the first copper sheet 701 is fixedly connected to the first partition 502 by a first screw 703. The first screw 703 is connected to the power supply for conducting electricity. For example, an alligator clip can be used to contact the first screw 703 with an external power supply to conduct electricity to the first copper block 702, so that a contact circuit is formed when the first copper block 702 contacts the side of the first copper ring 601. That is, in this embodiment, the first copper ring 601 is equivalent to a positive circuit and the second copper ring 602 is equivalent to a negative circuit.

The light strip slides in the material guiding channel 1003. The material guiding channel 1003 matches the width of the light strip. The first material blocking plate 1001 is provided at the front and rear ends thereof and extends toward the second material guiding plate 1002. 01-1, similarly, the second material guide plate 1002 is provided with a second material baffle plate 1002-1 symmetrically arranged with the first material baffle plate 1001-1, the first material baffle plate 1001-1 is above the material guide channel 1003, the light strip is slid and transported in the material guide channel 1003, and the left and right positions of the light strip are limited. At the same time, the first material baffle plate 1001-1 and the second material baffle plate 1002-1 limit the upper and lower positions of the light strip, which effectively ensures the stability of the light strip in the material guide mechanism 10, and ensures the accuracy and stability of the test.
