Description

Technical Field

[0001] The utility model relates to an integrated circuit curing box. Background Art

[0002] Integrated circuits are representatives of microelectronic devices. Through specific processes, various components and wirings are combined on semiconductor wafers or dielectric substrates to form microstructures. During the integrated circuit packaging process, to ensure the stability and reliability of circuit functions, UV glue is widely used for packaging, and a curing box is used for curing. However, the following deficiencies are found in the use of existing integrated circuit curing boxes and the analysis is as follows:

[0003] In an existing integrated circuit curing box, a placement rack is fixed inside. When curing, the working temperature inside the box is approximately around 150 - 200 °C (neither too high nor too low). After curing is completed, the front door of the box needs to be opened first, and then the integrated circuit board (workpiece) is taken from the placement rack and taken out of the box. During the operation process, due to the high temperature and large shape of the integrated circuit board on the placement rack inside the box, it is unsafe in the high-temperature environment when taking out the workpiece, and the operation is inconvenient. At the same time, when putting the next integrated circuit board (workpiece) into the box, because the temperature is still very high, it is also unsafe in the high-temperature environment when putting the workpiece in, and the operation is inconvenient. If the workpiece is taken out and put in after the box cools down, there are problems such as long waiting time, heat loss and insufficient energy conservation, and low work efficiency. Content of the Utility Model

[0031] The present utility model will be further described below with reference to the drawings and embodiments:

[0032] Embodiment 1: Refer to Figures 1-4 , an integrated circuit curing box, including a box body 1, a placement rack 2, curing lamps 3 and a driving mechanism 4. The curing lamps 3 are located inside the box body 1, and an orifice 1-1 is provided at the bottom side of the box body 1.

[0033] Among them, refer to Figures 3-4 , the driving mechanism 4 includes a horizontal guide rail 4-1, a sliding seat 4-2, a horizontal driving cylinder 4-3, a vertical driving cylinder 4-4, a telescopic vertical rod 4-5 and an orifice cover 4-6. The sliding seat 4-2 is slidably matched with the horizontal guide rail 4-1 and is driven to displace by the horizontal driving cylinder 4-3. The lower end of the telescopic vertical rod 4-5 is fixedly connected to the sliding seat 4-2, the orifice cover 4-6 is fixed to the upper end of the telescopic vertical rod 4-5 and is driven to displace by the vertical driving cylinder 4-4. The placement rack 2 is fixed on the upper surface of the middle part of the orifice cover 4-6.

[0034] Specifically, the telescopic vertical rod 4-5 includes a lower sleeve and an upper rod that are slidably engaged with each other. Since it belongs to the prior art, it will not be described in detail.

[0035] Specifically, refer to Figures 1-4 , the vertical driving cylinder 4-4 is vertically and fixedly installed on the sliding seat 4-2, and the output end of the vertical driving cylinder 4-4 faces upward and is fixedly connected to the hole cover 4-6.

[0036] Specifically, the curing lamp 3 uses a UV-LED lamp.

[0037] Specifically, both the horizontal driving cylinder 4-3 and the vertical driving cylinder 4-4 use telescopic cylinders.

[0038] Specifically, refer to Figures 1-4 , there are two horizontal guide rails 4-1 which are fixedly installed on the base 7 in parallel at intervals; the box body 1 is fixedly connected to the base 7 through a bracket 8; the horizontal driving cylinder 4-3 is horizontally and fixedly installed on the base 7. In addition, two limit stops 9 are respectively provided on the base 7 near both ends of the horizontal guide rail 4-1. Specifically, when the horizontal driving cylinder 4-3 drives the sliding seat 4-2 to slide along the horizontal guide rail 4-1 to the end position, the sliding seat 4-2 will be blocked and limited by the limit stop 9, which can ensure the accurate position of the sliding seat 4-2 when it reaches the displacement end position.

[0039] Further, the cross-section of the hole cover 4-6 is convex or in the shape of a capital omega. Specifically, the convex shape in the middle of the hole cover 4-6 is smaller than the hole opening 1-1, and the placement rack 2 is fixed on the upper surface of the convex part in the middle of the hole cover 4-6; and the hole opening 1-1 is sealed by the stepped edge of the hole cover 4-6.

[0040] Further, there are four telescopic vertical rods 4-5 which are distributed in a rectangle.

[0041] Further, an air inlet 1-2 is provided at the top of the box body 1, and an air inlet fan 5 is arranged at the air inlet 1-2. When curing, the temperature cannot be too high when the curing lamp 3 irradiates the integrated circuit board (workpiece). By means of the air inlet fan 5, cold air can be drawn into the box body 1 to cool down to 150 - 200 °C, ensuring that it is within the optimal curing temperature range, neither too low nor too high.

[0042] Further, an air outlet 1-3 is provided at the side of the box body 1, and an air outlet fan 6 is arranged at the air outlet 1-3. When curing, the temperature cannot be too high when the curing lamp 3 irradiates the integrated circuit board (workpiece). By means of the air outlet fan 6, the hot air in the box body 1 can be discharged, so that the temperature in the box body 1 is cooled down to 150 - 200 °C, ensuring that it is within the optimal curing temperature range, neither too low nor too high.

[0043] To improve the curing efficiency, high-power UV-LED lamps can be used. During high-power curing irradiation, a large amount of heat will be generated inside the box, and rapid heat dissipation is required to control the temperature within the range of 150 - 200 °C. Therefore, by combining the operation of the air inlet fan 5 and the exhaust fan 6, strong air cooling is achieved, and curing can be completed in an extremely short time, such as within 10 - 20 s.

[0044] In this embodiment, reference can be made to Figures 5-6 , during curing, the hole cover 4 - 6 covers the hole opening 1 - 1 of the box body 1, and the placement rack 2 and the integrated circuit board (workpiece) N thereon are located inside the box body 1. Curing (i.e., UV curing) is achieved by irradiating the integrated circuit board (workpiece) N with the curing lamp 3 (i.e., UV-LED lamp).

[0045] After curing is completed, the vertical driving cylinder 4 - 4 can be started to work and drive the hole cover 4 - 6 to move downward. The hole cover 4 - 6 drives the placement rack 2 and the integrated circuit board (workpiece) N thereon to move downward in place (reference can be made to Figure 7 ), then the horizontal driving cylinder 4 - 3 is started to work and drive the slide seat 4 - 2 to move away from the box body 1 and reach the in-place position. At this time, the placement rack 2 and the integrated circuit board (workpiece) N thereon are located beside the box body 1. At this time, the integrated circuit board (workpiece) N is completely exposed, and at this time, the integrated circuit board (workpiece) N is no longer in a high-temperature environment and can be quickly cooled. Then, the cured integrated circuit board (workpiece) N is taken away first, and then the next integrated circuit board (workpiece) to be cured is placed on the placement rack 2 (reference can be made to Figure 8 ); then the horizontal driving cylinder 4 - 3 can be started first to work and drive the slide seat 4 - 2 to be located below the box body 1 and reach the in-place position (reference can be made to Figure 9 ), and then the vertical driving cylinder 4 - 4 is started to work and drive the hole cover 4 - 6 to move upward to the in-place position (reference can be made to Figure 10 ). At this time, the hole cover 4 - 6 automatically covers the hole opening 1 - 1 of the box body 1 and the next integrated circuit board (workpiece) to be cured enters the box body 1 to prepare for curing (reference can be made to Figure 10 ).

[0046] Therefore, in this embodiment, the driving mechanism 4 can automatically take out the integrated circuit board (workpiece) that has been cured inside the box body 1 to outside the box, and at the same time, the integrated circuit board (workpiece) to be cured outside the box can also be automatically sent into the box, realizing automated operation and ensuring greater safety during the operation of taking out and putting in the integrated circuit board (workpiece). In addition, since the driving mechanism 4 can be started immediately after the integrated circuit board (workpiece) is cured to automatically take it out of the box and expose it to contact with low-temperature air completely, rapid cooling can be achieved; therefore, there is no need to wait for the temperature inside the box to drop before taking out and putting in the integrated circuit board (workpiece). Therefore, this integrated circuit board curing box has the advantages of reducing waiting time, reducing heat loss, being more energy-saving and environmentally friendly in work, and improving work efficiency.

[0047] Example 2: This example is basically the same as Example 1, except that:

[0048] See Figure 1 . A transparent observation window 1-4 is provided on the front side of the box body 1. It is convenient to observe the curing condition inside the box body 1, and problems inside the box can be discovered and handled in time when they occur.

[0049] Example 3: This example is basically the same as Example 1 or 2, except that:

[0050] See Figures 3-4 . The placement rack 2 includes a flat plate 2-1 and a stepped positioning pin 2-2. Four stepped positioning pins 2-2 are fixedly arranged on the flat plate 2-1 in a rectangular distribution; the flat plate 2-1 is fixed to the hole cover 4-6 by bolts 2-3.

[0051] Therefore, during use, the four mounting holes N-1 on the integrated circuit board (workpiece) N are respectively matched with the stepped positioning pins 2-2 for positioning. At the same time, there is a heat dissipation gap between the lower surface of the integrated circuit board (workpiece) and the upper surface of the flat plate 2-1, which is beneficial to the heat dissipation on the lower side of the integrated circuit board (workpiece) and can avoid the problem of overheating when the integrated circuit board (workpiece) is cured. The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art shall fall within the protection scope determined by the claims.
