Embodiment 1

[0020] Such as figure 1 , 2 As shown, a sintering oven with a small sintering port includes a sintering oven 1, a sintering port 2 and a limiting groove 3 matched with the sintering port 2, the sintering port 2 and the limiting groove 3 are arranged inside the sintering oven 1, The sintering port 2 includes a sintering port 20 and a sintering support rod 21. The sintering port 20 and the sintering support rod 21 are threadedly connected to facilitate the replacement of sintering ports 20 of different specifications to achieve the sintering process for LED lamps of different specifications. The sintering port 20 is spherical. The spherical sintering port 20 can dissipate heat evenly. There are several small sintering ports 201 on the sintering port 20. The positions of the small sintering ports 201 correspond to the dispensing positions. The distance between each small sintering port 201 and its corresponding dispensing position is Equal; each silver glue can be cured separate...

Embodiment 2

[0022] Based on the sintering oven with a small sintering port described in Example 1, a layer of rubber is provided on the inner wall of the limiting groove 3 . The rubber can act as a buffer when the LED lamp is placed on the limiting groove 3, preventing the position of the silver glue from moving when placed.

Embodiment 3

[0024] On the basis of a sintering oven with a small sintering port described in Embodiment 1 or 2, further optimization, the bottom of the limit groove 3 is provided with a rotating structure 4, and the rotating structure 4 includes a motor 40 and a driving wheel connected to the output shaft of the motor 41. The slave pulley 42 driven by the driving wheel and the belt 43 covered on the driving pulley 41 and the driven pulley 42 , the bottom of the limiting groove 3 is fixed at the center of the belt 43 . The rotating structure 4 rotates to realize the movement of the limiting groove. Before the sintering starts, the limiting groove is driven to move, which can realize the preheating of the LED lamp and prevent the silver glue from being suddenly heated to affect the later curing effect.

Abstract

The invention discloses a sintering baking oven with small sintering openings. The sintering baking oven comprises a sintering baking oven, a sintering opening and a limiting groove matched with the sintering opening, wherein the sintering opening and the limiting groove are arranged inside the sintering baking oven; the sintering opening comprises a sintering opening head and a sintering supporting rod, the sintering opening head is in threaded connection with the sintering supporting rod, the sintering opening head is spherical, a plurality of small sintering openings are formed in the sintering opening head, the positions of the small sintering openings correspond to dispensing positions, and the distances between each small sintering opening and the corresponding dispensing position are the same; glass is adopted on one side wall of the sintering baking oven, and the glass is arranged on the side wall of the sintering baking oven facilitating to the observation of a silver colloidsintering condition. The small sintering openings corresponding to the dispensing positions are formed, compared with an existing sintering technology, the sintering efficiency in the technology is higher, each silver colloid can be solidified respectively, the solidification time is approximately the same, and the solidification time of the colloid at each position is different during integral sintering to cause that the sintering time is increased, so that the sintering time is also reduced in the technology, and the efficiency in the whole LED lamp preparation technology is improved.

Description

technical field [0001] The invention relates to the technical field of LED lamp preparation, in particular to a sintering oven with a small sintering port. Background technique [0002] Traditional lighting is usually achieved by using incandescent lamps. Incandescent lamps use filaments to gather heat generated when current passes through the filaments, making the temperature of the filaments reach an incandescent state above 2000 degrees Celsius, so that the filaments emit light for lighting. In this process, incandescent lamps It needs to consume more heat to emit light, which is a waste of energy. In this context, people use diodes to make LED energy-saving lamps, which convert electrical energy into light directly through diodes to achieve lighting, reduce the energy consumed by bulb lighting, and achieve the purpose of energy saving and environmental protection. [0003] In the LED lamp packaging process, it connects the outer leads to the electrodes of the LED chip, ...
