[0002] LED packaging chip is a solid-state semiconductor device. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. It is also called LED light-emitting chip, which is an LED lamp. The core component of the LED package, that is, the P-N junction, its main function is to convert electrical energy into light energy. At present, in the production process of LED packaged chips, in order to ensure product quality, the staff need to test the conductivity of the LED packaged chip. However, in the actual operation process, the staff needs to carry out frequent loading and unloading, which not only has a low degree of automation, but also affects the efficiency of detection

Embodiment
[0027] The LED package chip detection device includes a bottom plate 1, a worktable 2 is fixedly connected to the top of the bottom plate 1, a storage box 4 is fixedly connected to one side of the top of the worktable 2, and a chute is opened inside the worktable 2 and below the storage box 4 5. A material guide plate 6 is slidably connected inside the chute 5, and a material groove 7 is opened inside the material guide plate 6, which can receive the chips to be tested, so as to facilitate subsequent detection. Symmetrical opening slot 8 is provided, and a rotating plate 9 is symmetrically connected to the inside of the storage box 4, and the two rotating plates 9 both extend to the inside of the opening slot 8, so that the detected chips can be pushed out from the inside of the slot 7, thereby Instead of manual cutting, it is beneficial to improve the detection efficiency. A drive assembly 10 is provided on the top of the worktable 2, a detection box 11 is fixedly connected to...

The invention discloses an LED packaging chip detection device and method, and the device comprises a bottom plate, the top of the bottom plate is fixedly connected with a workbench, one side of the top of the workbench is fixedly connected with a material storage box, a sliding groove is formed in the workbench and is located below the material storage box, the interior of the sliding groove is slidably connected with a material guide plate, and the interior of the material guide plate is provided with a material groove. The automatic feeding and discharging device is compact in structure, easy and convenient to operate and high in practicability, the driving assembly is used in cooperation with the material guiding plate, automatic feeding and discharging operation can be conducted on a to-be-tested chip, and the automatic feeding and discharging device is high in practicability, convenient to operate, high in practicability and suitable for popularization and application. According to the technical scheme, an original manual operation mode can be replaced, the working efficiency of the equipment can be improved, meanwhile, the distance between the two conductive wheels can be adjusted through matched use of the cross rod and the sliding plate, so that the equipment is suitable for chips of different specifications, and the application range of the equipment is widened.
Description
technical field [0001] The invention relates to an LED package chip detection device and a detection method, in particular to an LED package chip detection device, and belongs to the technical field of detection devices. Background technique [0002] The LED package chip is a solid-state semiconductor device. One end of the chip is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire chip is encapsulated by epoxy resin, also known as the LED light-emitting chip, which is an LED lamp. Its main function is to convert electrical energy into light energy. At present, in the production process of LED package chips, in order to ensure product quality, staff need to test the continuity of LED package chips. However, in the actual operation process, the staff needs to carry out frequent loading and unloading, which not only has a low degree of automation, but also affects the work e...
