Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, in particular to a novel front-end solid crystal dispensing head. Background Art

[0002] With the extensive application of LED lamp beads, the market demand for LED lamp beads is increasing, and the pressure on packaging production capacity is gradually increasing. In order to improve the efficiency and yield of packaging production capacity, many workstations have been improved. Due to the small number of production technicians, the large-scale order change and modification of the production line involves a long time-consuming replacement of the dispensing head, which results in multiple die bonding machines being shut down and waiting for operation, or when the production line technicians are changing shifts or taking a break, multiple die bonding machines are waiting for the replacement of the die bonding dispensing head, and no one is handling it. In addition, due to the hasty replacement of the die bonding dispensing head when changing orders, there are replacement errors, crooked installation, etc., which cause abnormalities such as excessive glue, insufficient glue, and glue throwing. Therefore, it is necessary to reduce abnormalities, improve processes, and improve production efficiency, reduce the scrapping of finished lamp beads caused by human factors, and improve the production yield and production efficiency of patch products such as EMC3030, RGB, and 2835. The existing die bonding machine has low production efficiency and the level of machine automation needs to be improved. At present, it is still very dependent on personnel to operate, which affects production efficiency and low machine utilization. The influence of human factors causes excessive glue, insufficient glue, and glue throwing, which can easily cause fatal defects to the product and affect the improvement of production yield.

[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0014] Reference Figure 1-4 This specific implementation adopts the following technical scheme: a new type of front-end solid crystal dispensing head, including a pressure rod 1, a sleeve 2, a push rod 3 and a dispensing head 33, the sleeve 2 is provided with a pressure rod 1 and a push rod 3, the pressure rod 1 is provided with a circle of triangular heads 11, the sleeve 2 is evenly provided with guide grooves 21, the guide grooves 21 cooperate with the pressure rod 1 and the push rod 3, four oblique structures 31 are provided under the push rod 3, a dispensing disk 32 is provided on the oblique structure 31, a plurality of dispensing heads 33 are provided on the dispensing disk 32, and the dispensing heads 33 cooperate with the spring.

[0015] It is worth noting that the pressure rod 1 and the push rod 3 are in top contact with each other.

[0016] The dispensing head 33 is provided with a protrusion inside.

[0017] The top end of the guide groove 21 is an oblique opening.

[0018] The top of the push rod 3 is provided with a disc 34 corresponding to each dispensing head.

[0019] This specific implementation method is to combine various die bonding dispensing heads together to match the corresponding dispensing heads according to each different chip. The working principle is to eject the dispensing head matching the chip into place through a sleeve, a pressure rod, and a push rod before performing the dispensing operation.

[0020] The pressure rod of the present specific implementation method is a structure with a circle of triangular heads, and there is a circle of evenly distributed guide grooves inside the sleeve. The top of the guide groove is beveled and arranged at intervals, and the push rod is a structure with four beveled mouths at the bottom, and a disc is on the top, which corresponds to each dispensing head one by one and confirms the dispensing head to be used by rotation. After being assembled together, the pressure rod and the push rod are both in the guide groove, and the dispensing head and spring are retracted at the top; it is pushed toward the dispensing head at the bottom. At this time, the pressure rod presses the push rod downward and is completely in the guide groove and has not come out. At the moment the pressure rod pushes the push rod out of the guide groove, there is no guide groove restriction, and the push rod rotates. Because the pressure rod is on the inclined surface of the push rod, the spring below pushes it and slides over directly. Because of the effect of the inclined surface force component, the push rod is always subjected to lateral force, but it is blocked by the guide groove. It slides over directly at the moment of coming out of the guide groove, with seamless connection, and it will be smoother when switching the dispensing heads. When a certain dispensing head is needed, rotate the dispensing disc to aim at it and press it. There is a protrusion inside each dispensing head. When a dispensing head is pressed down, it is stuck under the protrusion of other dispensing heads. When the top button is pressed or other dispensing heads are pressed, the protrusion is driven downward. Since the place where the dispensing head is stuck is an inclined surface, when the protrusion is downward, the dispensing head is squeezed out and the spring bounces the dispensing head up.

[0021] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
