Description

Technical Field

[0001] The invention belongs to the field of chip dispensing, in particular to an LED chip dispensing device. Background Art

[0002] LED chip, also known as LED light-emitting chip, is the core component of LED lamp. Its main function is to convert electrical energy into light energy. The main material of the chip is single crystal silicon. The main purpose of LED chip dispensing is to ensure that the LED chip can achieve good electrical connection, optical performance and mechanical stability during the packaging process.

[0003] Glue dispensing can firmly fix the LED chip on the substrate to prevent the chip from moving or falling off during the packaging process, ensuring the mechanical stability of the package. Glue dispensing can also protect the LED chip from the influence of the external environment, such as dust, moisture, etc., thereby extending the service life of the chip.

[0004] Traditional dispensing devices often have one or two dispensing nozzles, which are then controlled by a precise moving module to move one by one to the top surface of the LED chip, and then the glue is sprayed on the surface of the LED chip. This method not only requires that the movement error of the moving module be extremely small each time, but also requires the setting of a more complex moving program. Otherwise, it is easy to have problems with dispensing deviations, and since more moving steps are required, the dispensing efficiency is affected.

[0005] To this end, the present invention provides a LED chip glue dispensing device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

Through this setting, the path that the dispensing gun needs to move is greatly reduced, and the dispensing misalignment problem caused by the accumulation of slight gaps after the dispensing gun moves multiple times is greatly reduced. In addition, the efficiency of the dispensing process is also improved due to the reduction of moving steps; after the dispensing is completed and before each dispensing begins, the multiple dispensing guns are cleaned through the cleaning table to ensure normal dispensing work. Before each dispensing, the optical positioning module locates the accurate dispensing position through the reflection of the optical signal to ensure the accuracy of dispensing.

[0012] Preferably, two transfer valves are fixedly connected to the top of the dispensing box, and a connecting seat for communicating with the outside world is fixedly connected to the top of the processing box. The connecting seat and the transfer valve are connected through a spiral transfer tube, one of the transfer valves is used to transfer glue, and the other transfer valve is used to vacuum and inject protective gas.

[0017] The beneficial effects of the present invention are as follows: 1. The LED chip dispensing device described in the present invention is provided with a plurality of movable dispensing guns. Since the arrangement and position of the LED chips on each LED chip board are basically the same, and the same LED chip board is used in the same batch of dispensing processes, the position of the dispensing gun in the dispensing device can be adjusted before the dispensing process, so that the arrangement of the dispensing gun and the arrangement and indirection of the LED chips on the LED chip board are the same, and the dispensing work can be completed by positioning the dispensing only once; if the number of LED chips is large, the number of dispensing guns required can also be reduced by multiples, such as: if the number of LED chips is fifty times fifty, then five times five dispensing guns can be used for dispensing. Through this arrangement, the path that the dispensing gun needs to move is greatly reduced, which greatly reduces the problem of dispensing misalignment caused by the accumulation of slight gaps after the dispensing gun has been moved multiple times, and since the moving steps are reduced, the efficiency of the dispensing process is also improved.

Through this arrangement, the path that the dispensing gun 17 needs to move is greatly reduced, and the problem of dispensing misalignment caused by the accumulation of slight differences after the dispensing gun 17 moves multiple times is greatly reduced. In addition, due to the reduction in moving steps, the efficiency of the dispensing process is also improved. When the dispensing is completed and before each dispensing begins, the multiple dispensing guns 17 are cleaned by the cleaning table 5 to ensure normal dispensing work.
