Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of semiconductor chip packaging auxiliary equipment, and more specifically relates to a movable magazine for heat dissipation covers. Background Art
[0002] With the continuous development of the integration of packaging technologies, heat dissipation cover attachment on chips has become an efficient heat dissipation method in single-chip BGA packaging products. To cooperate with automated production, the magazine carrier for heat dissipation covers has also become an essential tool during the chip attachment process.
[0003] Traditional magazines all have a window structure with a fixed size and can only hold heat dissipation covers of specific sizes, which has obvious limitations. Over time, as the sizes of heat dissipation covers for different products change, corresponding heat dissipation cover magazines also need to be synchronized. This not only causes great waste of resources, but also increases the difficulty in the management process of tools, as well as the problem of difficult selection of jigs during the engineering batch development stage.
[0004] Therefore, in view of these limitations of current traditional magazines, it is necessary to develop a new type of magazine that can accommodate heat dissipation covers of various sizes, reduce the management difficulty, and solve the problem of difficult selection of jigs during the engineering batch development stage, so as to better meet the actual needs of the semiconductor packaging industry. Summary of the Utility Model
[0005] To solve the above problems, the utility model provides a movable magazine for heat dissipation covers, which breaks through the limitations of product size specifications, greatly improves the utilization rate of tools, solves the problem of difficult selection of jigs during the engineering batch development stage, and reduces the management difficulty.
[0006] According to one aspect of the present utility model, a heat dissipation cover movable bin is provided, which includes a base, a tray, and a rack. The tray is liftable and placed on the base. The base is provided with an avoidance hole to allow a lifting mechanism to drive the tray to lift. There are at least two groups of racks, which are diagonally arranged relative to the center of the tray. The rack includes a vertically arranged L-shaped angle limiting frame, a slider provided on the outer wall of the bottom of the L-shaped angle limiting frame, and a guide rail adapted to the slider. The guide rail is inclined at 45° relative to the cross center line of the tray and arranged on the base. The slider is movably installed on the guide rail. The L-shaped angle limiting frame includes a first side wall and a second side wall, and the first side wall and the second side wall are arranged at a right angle to form an "L" shaped structure. A bin for placing heat dissipation covers is formed above the tray and between the racks. The position of the slider is moved to expand or contract the bin for placing heat dissipation covers. The tray is raised to push the stacked heat dissipation covers to move upward along the inner walls of the first side wall and the second side wall. Thus, according to the size of the heat dissipation cover, the position of the slider is adjusted. After confirming the distance between the heat dissipation cover and the inner wall of the bin, the slider is positioned. The heat dissipation covers are stacked and placed on the tray. The adjacent sides of one corner of the heat dissipation cover are close to the first side wall and the second side wall of a group of racks. The tray is raised to convey the stacked heat dissipation covers upward in the bin. By using the slider and the guide rail, the movement of the L-shaped angle limiting frame is realized. By comparing with the actual size of the heat dissipation cover before operation, the size of the window of the bin is adjusted, so as to achieve the purpose of sharing a bin for heat dissipation covers of different sizes, reduce the later input cost of bin tools, simplify the difficulty of tool management, and reduce the difficulty of selecting jigs in the engineering batch development stage.
[0007] In some embodiments, the tray includes a tray and a cross bracket. The cross bracket has four support rods distributed in a cross shape. The tray is fixed at the center of the cross bracket. A connection hole is provided at the center of the cross bracket to externally connect a lifting mechanism. Thus, the tray holds the heat dissipation cover. For larger-sized heat dissipation covers, when the window size of the bin increases, the support rods of the cross bracket can hold the four sides of the heat dissipation cover from four directions, ensuring the stability of the heat dissipation cover in the bin.
[0008] In some embodiments, upwardly bent lifting portions are provided at the ends of all four support rods. Thus, for larger-sized heat dissipation covers, when the size of the heat dissipation cover is larger than that of the cross bracket, the lifting portions can be used to lift the heat dissipation cover from the bottom. With the lifting support in four directions, the stability of the heat dissipation cover in the bin can be ensured.
[0009] In some embodiments, there are four groups of racks, and two groups are diagonally arranged relative to the center of the tray in pairs. Thus, the four corners of the heat dissipation cover can be guided and limited. The four groups of racks move inward or outward along their respective guide rails to realize the free adjustment of the window size of the bin to meet the production requirements.
[0010] In some embodiments, the slider is provided with a screw hole, and the screw hole is configured with a positioning screw to press against the guide rail to lock the position of the slider. Thus, when it is necessary to adjust the size of the window of the bin, loosen the positioning screw, move the slider to the desired position, and then lock the positioning screw to press against the guide rail to achieve the positioning of the slider.
[0011] In some embodiments, each set of sliders of the rack is configured with two guide rails, and the guide rails are of T-shaped structure. Thus, the smooth movement of the slider can be ensured, and effectively ensure the stability of the position of the L-shaped angle limit frame after the size of the bin is locked.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The heat dissipation cover movable bin provided by the present utility model enables the position of the L-shaped angle limit frame to move through the slider and the guide rail, realizes the free adjustment of the window size of the bin, enables the heat dissipation cover movable bin to be compatible with the sizes of common square heat dissipation covers on the market, achieves the purpose of sharing a bin for different-sized heat dissipation covers, reduces the tool cost of purchasing a specific-sized bin and the corresponding time cost due to the change of the heat dissipation cover size, avoids resource waste, simplifies the management cost of the bin tools, and makes the selection of jigs more convenient in the engineering batch development stage and the production stage.

[0018] The present utility model will be further described below in conjunction with the specific embodiments.
[0019] Embodiment 1
[0020] As Figure 1 and 2As shown in the figure, a heat dissipation cover movable bin according to an embodiment of the present utility model includes a base 1, a tray 2, and a rack 3. The tray 2 is located on the base 1, and the tray 2 can be lifted up and down relative to the base 1. The base 1 is provided with an avoidance hole 11 to allow a lifting mechanism (not shown in the figure) to drive the tray 2 to lift. The lifting mechanism for driving the tray 2 to lift is a push rod, which is available on the chip packaging equipment. The heat dissipation cover movable bin provided in this application is a tool for packaging, and the lifting mechanism does not belong to the tool part of the bin, so it is not shown in the figure.
[0021] There are at least two groups of racks 3. In this embodiment, there are four groups of racks 3, and two of them are in a group and are diagonally arranged relative to the center of the tray 2. Each group of racks 3 specifically includes a vertically arranged L-shaped angle limiting frame 31, a slider 32 provided on the outer wall of the bottom of the L-shaped angle limiting frame 31, and a guide rail 33 adapted to the slider 32. The L-shaped angle limiting frame 31 includes a first side wall 311 and a second side wall 312. The first side wall 311 and the second side wall 312 are vertically upward and perpendicular to the base 1. The first side wall 311 and the second side wall 312 are welded and fixed, and the connection part is set at a right angle to form an "L" - shaped structure. The slider 32 is welded to the outer wall of the bottom of the L-shaped angle limiting frame 31. The structures of the first side wall 311 and the second side wall 312 are the same, and the slider 32 can be welded to the outer wall of the first side wall 311 or the second side wall 312 according to needs. The slider 32 is movably installed on the guide rail 33. The guide rail 33 is inclined at 45° relative to the cross center line of the tray 2 and is arranged on the base 1 in a left - right symmetric distribution centered on the tray 2. Above the tray 2 and between the racks 3 form a bin 100 for placing heat dissipation covers. By moving the position of the slider 32, the size of the bin 100 for placing heat dissipation covers can be enlarged or reduced. When the tray 2 is lifted, the stacked heat dissipation covers can be pushed to move upward along the inner walls of the first side wall 311 and the second side wall 312.
[0022] Preferably, there are four groups of racks 3. In this way, it can play a guiding and limiting role for the four corners of the heat dissipation cover, that is, it can limit both ends of the four sides of the heat dissipation cover. The four groups of racks 3 move inward or outward along their respective guide rails 33 to realize the free adjustment of the window size of the bin 100 to meet the production requirements.
[0023] Such as Figure 1 、 Figure 3 and Figure 4As shown, the tray base 2 includes a tray 21 and a cross bracket 22. The tray 21 is a square sheet structure, and the cross bracket 22 is in a cross shape and has four support rods 221 distributed in a cross. The tray 21 is fixed to the center of the cross bracket 22 by four screws. A connection hole 223 is provided at the center of the cross bracket 22, and this connection hole 223 is used to connect to a lifting mechanism, such as connecting a push rod. The tray 21 holds the heat dissipation cover. For a larger-sized heat dissipation cover, when the window size of the bin 100 increases, the support rods 221 of the cross bracket 22 can hold the four sides of the heat dissipation cover from four directions to ensure the stability of the heat dissipation cover in the bin 100.
[0024] As Figure 1 shown, upwardly bent lifting portions 222 are provided at the ends of all four support rods 221. For an even larger-sized heat dissipation cover, when the size of the heat dissipation cover is larger than that of the cross bracket 22, the lifting portions 222 can be used to lift the heat dissipation cover from the bottom. With the lifting support from four directions, the stability of the heat dissipation cover in the bin 100 can be ensured.
[0025] As Figure 1 shown, screw holes 321 are provided in the slider 32, and positioning screws 322 are arranged in the screw holes 321 to tighten against the guide rail 33 to lock the position of the slider 32. When it is necessary to adjust the window size of the bin 100, loosen the positioning screw 322, move the slider 32 to the desired position, and then tighten the positioning screw 322 to tighten against the guide rail 33 to achieve the positioning of the slider 32.
[0026] Each set of the sliders 32 of the rack 3 is provided with two guide rails 33, and the guide rails 33 are of a T-shaped structure. It can ensure the smooth movement of the slider 32 and effectively guarantee the stability of the position of the L-shaped angle limit frame 31 after the size of the bin 100 is locked. Although there are two guide rails 33, only one of the guide rails 33 needs to be provided with a positioning screw 322.
[0027] When using this movable bin for the heat dissipation cover, according to the size of the heat dissipation cover, adjust the position of the slider 32, use a plug gauge to confirm the distance between the heat dissipation cover and the inner wall of the bin 100, and then tighten the positioning screw 322 to tighten against the guide rail 33 to position the slider 32. Stack the heat dissipation covers on the tray base 2, and the adjacent sides of the four corners of the heat dissipation cover are respectively close to the first side wall 311 and the second side wall 312 of a set of racks 3. When lifting the tray base 2 with a push rod, the stacked heat dissipation covers are conveyed upward in the bin 100. This movable bin for the heat dissipation cover realizes the movement of the L-shaped angle limit frame 31 by using the slider 32 and the guide rail 33. By comparing with the actual size of the heat dissipation cover before the operation and adjusting the window size of the bin 100, the purpose of sharing one bin for heat dissipation covers of different sizes is achieved, reducing the later input cost of bin tools, simplifying the difficulty of tool management, and reducing the difficulty of selecting jigs in the engineering batch development stage.
[0028] Embodiment 2
[0029] The difference between this embodiment and Embodiment 1 lies only in the different number of material racks 3. As Figure 5 shown, in this embodiment, the material racks 3 are arranged in two groups, and the two groups of material racks 3 are diagonally arranged relative to the center of the tray 2. The two groups of diagonally arranged material racks 3 move away from or close to the center of the tray 2 at the same time, which can realize the change of the size of the window opening of the bin 100. If two groups of material racks 3 are set, the first side wall 311 and the second side wall 312 of the L-shaped angle limiting frame 31 can be set a little longer, which can better play a guiding role for the heat dissipation cover with a slightly larger size.
[0030] For the movable bin of the heat dissipation cover provided by the present utility model, the position of the L-shaped angle limiting frame 31 can be moved through the slider 32 and the guide rail 33, so as to realize the free adjustment of the window opening size of the bin 100, make the movable bin of the heat dissipation cover compatible with the common square heat dissipation cover sizes on the market, achieve the purpose of sharing a bin for different sizes of heat dissipation covers, reduce the tool cost of purchasing a specific size bin and the corresponding time cost due to the change of the heat dissipation cover size, and avoid waste of resources. At the same time, it also simplifies the management cost of the bin tool, making it more convenient to select the fixtures in the engineering batch development stage and the production stage.
[0031] The above are only some embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present utility model, other deformations and improvements can be made, and these all belong to the protection scope of the present utility model.
