Description

Technical Field

[0001] This invention relates to the field of integrated circuit packaging technology, and in particular to an adjustable clip structure and feeding method suitable for automated heat sink mounting. Background Technology

[0002] The magazine is used for batch storage and orientation sorting of heat sinks. It can be used as a "disposable hopper" for offline loading, stacking heat sinks to ensure that the posture of each subsequent gripper by the robot or pick-and-place machine is consistent, reducing visual positioning time. It is often used in the feeding structure of automated heat sink mounting equipment.

[0003] Traditional magazine structures use dedicated magazines, with the magazine's inner cavity machined to conform to the shape of the heatsink. The tolerance is typically only +0.2mm. If the product is modified (heatsink size changes), a new magazine must be manufactured. For heatsinks of different shapes and sizes, corresponding magazines must also be made individually, resulting in high hardware costs, especially for multi-variety, small-batch production, leading to significant cost consumption. There is an urgent need for an adjustable magazine structure and feeding method suitable for automated heatsink mounting. Summary of the Invention

[0004] Therefore, this invention provides an adjustable clip structure and feeding method suitable for automated heat sink mounting, which can achieve compatibility with heat sinks of different sizes within a certain range, improve clip compatibility, reduce the types of clips for easy maintenance, greatly improve economy and practicality, and has significant effects on multi-variety or "fragmented order" assembly modes.

[0005] To solve the above-mentioned technical problems, the present invention provides an adjustable clip structure suitable for automated heat sink mounting, comprising: Heat sink support plate; The magazine main frame includes a base plate, two opposing wall plates, a horizontal plate disposed between the two wall plates, and a plurality of limiting posts disposed on the base plate; The base plate is provided with heat sink support holes, and the heat sink support plate is placed at the heat sink support holes and used to support the heat sink; The base plate is provided with adjustable slides corresponding to the plurality of limiting posts. The limiting posts can move and adjust along the corresponding adjustable slides. The plurality of limiting posts surround and form a limiting space for the heat sink, thereby adapting heat sinks of different shapes and sizes within the adjustment range of the adjustable slides.

[0006] In one embodiment of the present invention, the two wall panels are respectively fixed to the base plate by wall panel fixing screws.

[0007] In one embodiment of the present invention, the horizontal plate is fixed between the two wall panels by horizontal plate fixing screws.

[0008] In one embodiment of the present invention, the limiting post is installed on the corresponding adjustable slide by the limiting post fixing screw and can move and adjust along the adjustable slide. After adjustment, it is locked and fixed by the corresponding limiting post fixing screw.

[0009] In one embodiment of the present invention, each of the limiting posts is fixed by two limiting post fixing screws.

[0010] In one embodiment of the present invention, the number of the limiting posts is four, and they are evenly spaced around the circumferential support hole of the heat sink.

[0011] In one embodiment of the present invention, each of the limiting posts is provided with two parallel adjustable slides; the angle between each adjustable slide and the wall panel is 45°.

[0012] In one embodiment of the present invention, the heat sink support plate includes a rectangular central base, and the four sides of the central base form four outwardly protruding support arms. The central bottom of the central base is provided with a lifting groove coaxially arranged with the heat sink support hole. Each of the limiting posts is located in the four corner areas of the central base and is provided with a V-shaped limiting structure facing the corresponding corner area.

[0013] In one embodiment of the present invention, the heat sink support hole is a through hole penetrating the base plate and is used for the lifting device of the equipment to pass through and lift the heat sink support plate.

[0014] The present invention also provides a method for feeding heat sinks, utilizing the adjustable clip structure suitable for automated heat sink mounting, the feeding method comprising: Place the heat sink support plate at the heat sink support hole on the base plate; Multiple limiting posts are moved and adjusted along the adjustable slide of the base plate to form a limiting space that matches the outer dimensions of the target heat sink, and the limiting posts are locked and fixed by the limiting post fixing screws. The heat sink layers are stacked on the heat sink tray and the cartridges are loaded into the automated mounting equipment; The heat sink support plate is lifted by the equipment lifting device through the heat sink support hole to lift the heat sink, thereby realizing the subsequent automated pick-up and mounting of the heat sink.

[0015] The technical solution of the present invention has the following advantages compared with the prior art: This invention discloses an adjustable clip structure and feeding method for automated heat sink mounting. It utilizes an adjustable slide rail on a base plate in conjunction with movable limiting posts along the slide rail, creating a variable limiting space. Within the adjustable range of the slide rail, heat sinks of different shapes and sizes can be compatiblely positioned using the same clip. This avoids the problem of traditional dedicated clips requiring conformal machining to the heat sink shape, necessitating clip remanufacturing for size changes. Structurally, it solves the problem of multiple clips for multiple heat sink specifications, significantly reducing clip types, lowering fixture investment and spare parts costs. It is particularly suitable for production modes with multiple varieties, small batches, and fragmented orders. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

Therefore, it should not be construed as a limitation of this invention.

[0029] In this invention, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention based on the specific content of the technical solution.

[0030] Example 1 Reference Figures 1 to 6 As shown, an adjustable clip structure suitable for automated heat sink mounting in this embodiment includes: Heat sink support plate B; The magazine main frame A includes a base plate 102, two opposing wall plates 100a, a horizontal plate 107 disposed between the two wall plates 100a, and a plurality of limiting posts 200 disposed on the base plate 102. The base plate 102 is provided with heat sink support holes 132, and the heat sink support plate B is placed at the heat sink support holes 132 and used to support the heat sink. The base plate 102 is provided with adjustable slides 500 corresponding to the plurality of limiting posts 200. The limiting posts 200 can move and adjust along the corresponding adjustable slides 500. The plurality of limiting posts 200 surround and form a limiting space for the heat sink, thereby adapting heat sinks of different shapes and sizes within the adjustment range of the adjustable slides 500.

[0031] Specifically, the two wall panels 100a are respectively fixed to the base plate 102 by wall panel fixing screws 400.

[0032] Specifically, the horizontal plate 107 is fixed between the two wall panels 100a by horizontal plate fixing screws 300.

[0033] Specifically, the limiting post 200 is installed on the corresponding adjustable slide 500 by the limiting post fixing screw 600 and can move and adjust along the adjustable slide 500. After adjustment, it is locked and fixed by the corresponding limiting post fixing screw 600.

[0034] Specifically, each of the limiting posts 200 is fixed by two limiting post fixing screws 600.

[0035] Specifically, there are four limiting posts 200, which are evenly spaced around the circumferential support hole 132 of the heat sink. The multiple limiting posts 200 evenly spaced around the circumferential support hole 132 can form multi-directional shape constraints on the heat sink on the heat sink support plate B, so that the position and posture of the heat sink in the inner cavity of the magazine remain consistent, thereby improving the success rate of material picking and the consistency of mounting.

[0036] Specifically, each of the limiting posts 200 is provided with two parallel adjustable slides 500, and the limiting posts 200 are fixed by two limiting post fixing screws 600, which can effectively improve the torsional resistance of the limiting posts 200 after locking, and prevent the limiting posts 200 from shifting during heat sink stacking pressure, equipment vibration or lifting material removal, thereby improving positioning accuracy and long-term stability.

[0037] Specifically, the angle between each adjustable slide 500 and the wall panel 100a is 45°. When the limiting post 200 is adjusted along this direction, the limiting boundary can be changed simultaneously in two orthogonal directions, effectively improving the coverage of dimensional changes in the long and short sides of the heat sink. Compared to a structure that adjusts only in a single direction, this arrangement can achieve more flexible limiting space changes within a smaller mechanical space, improve the adaptation efficiency to heat sinks of different shapes and sizes, and reduce adjustment steps and trial assembly times.

[0038] Specifically, refer to Figures 7 to 8 As shown, the heat sink support plate B includes a rectangular central base 11b, and the four sides of the central base 11b form four outwardly protruding support arms 12b. This structure ensures that the heat sink support plate B has a supporting surface in four directions, facilitating stable support for the bottom surface of the heat sink. The outer edge of the heat sink support plate B adopts a rounded transition profile to reduce scratching interference during loading and lifting.

[0039] The central base 11b is provided with a lifting groove 13b coaxially arranged with the heat sink support hole 132 at its central bottom. Each of the limiting posts 200 is located in the four corner areas of the central base 11b and is provided with a V-shaped limiting structure 201 facing the corresponding corner area, so as to form a centripetal limiting on the shape of the heat sink, which can limit the lateral displacement of the heat sink in the plane and also limit the rotational freedom of the heat sink in the plane.

[0040] Specifically, the heat sink support hole 132 is a through hole penetrating the base plate 102, and is used for the equipment's lifting device to pass through and lift the heat sink support plate B. The equipment lifting device can lift the heat sink support plate B through this support hole to lift the heat sink, which facilitates stable lifting and gripping of each heat sink, and improves the reliability of automated feeding.

[0041] This embodiment also provides a heat sink loading method, utilizing the adjustable clip structure suitable for automated heat sink mounting, the loading method including: S1. Place the heat sink support plate B at the heat sink support hole 132 of the base plate 102; S2. Move and adjust multiple limiting posts 200 along the adjustable slide 500 of the base plate 102 to form a limiting space that matches the outer dimensions of the target heat sink, and lock the limiting posts 200 with limiting post fixing screws 600. S3. Stack the heat sink layers on the heat sink tray B and load the cartridge into the automated mounting equipment; S4. The heat sink support plate B is lifted by the equipment lifting device through the heat sink support hole 132 to lift the heat sink, thereby realizing the subsequent automated pick-up and mounting of the heat sink.

[0042] Example 2 Reference Figures 1 to 8 As shown, this embodiment provides an adjustable clip structure suitable for automated heat sink mounting, including a clip main frame A and a heat sink support plate B; wherein, the clip main frame A is composed of a first wall plate 100, a second wall plate 101, a base plate 102, a horizontal plate 107, and a plurality of limiting posts disposed on the base plate 102, the plurality of limiting posts including a first limiting post 103, a second limiting post 104, a third limiting post 105, and a fourth limiting post 106.

[0043] The first wall panel 100 and the second wall panel 101 are arranged opposite to each other and are respectively fixed to the base plate 102 by wall panel fixing screws 400. Specifically, the first wall panel 100 is connected and fixed to the base plate 102 by first wall panel fixing screw 110, first wall panel fixing screw 111, and first wall panel fixing screw 112; the second wall panel 101 is connected and fixed to the base plate 102 by second wall panel fixing screw 113, second wall panel fixing screw 114, and second wall panel fixing screw 115. The distance between the two wall panels 100a forms one of the inner cavity boundaries of the magazine main frame A and defines the theoretical maximum range of the adjustable magazine structure that can adapt to the shape and size of the heat sink.

[0044] The base plate 102 is provided with adjustable slides 500 corresponding one-to-one with multiple limiting posts 200. These adjustable slides are circumferentially distributed around the heat sink support holes 132. Each limiting post corresponds to two parallel adjustable slides 500, thus forming four sets of double-slide structures. Specifically: The first limiting post 103 corresponds to the first limiting post adjustable slide rail one 116 and the first limiting post adjustable slide rail two 117; The second limiting post 104 corresponds to the second limiting post adjustable slide rail one 122 and the second limiting post adjustable slide rail two 123; The third limiting post 105 corresponds to the third limiting post adjustable slide rail one 120 and the third limiting post adjustable slide rail two 121; The fourth limit post 106 corresponds to the fourth limit post adjustable slide rail one 118 and the fourth limit post adjustable slide rail two 119.

[0045] In this arrangement, four limiting posts are evenly spaced around the heat sink support hole 132, forming a ring-shaped limiting structure on the base plate 102 to jointly enclose and form a limiting space for the heat sink.

[0046] The first limiting post 103 is installed at the first limiting post adjustable slide rail 116 and the first limiting post adjustable slide rail 2 117 by the first limiting post fixing screw 124 and the first limiting post fixing screw 2 125, and can move and adjust along the corresponding adjustable slide rail. The second limiting post 104 is installed at the second limiting post adjustable slide rail 122 and the second limiting post adjustable slide rail 123 by the second limiting post fixing screw 126 and the second limiting post fixing screw 127, and can move and adjust along the corresponding adjustable slide rail. The third limiting post 105 is installed at the third limiting post adjustable slide rail 120 and the third limiting post adjustable slide rail 2 121 by the third limiting post fixing screw 128 and the third limiting post fixing screw 2 129, and can move and adjust along the corresponding adjustable slide rail. The fourth limiting post 106 is installed at the fourth limiting post adjustable slide rail 118 and the fourth limiting post adjustable slide rail 2 119 by the fourth limiting post fixing screw 130 and the fourth limiting post fixing screw 2 131, and can move and adjust along the corresponding adjustable slide rail.

[0047] After adjustment, the positions of the limiting posts are fixed by tightening the corresponding two limiting post fixing screws. The length of each adjustable slide limits the movable range of the corresponding limiting post, thereby making the limiting space adjustable within this range and thus achieving adaptation to heat sinks of different shapes and sizes.

[0048] The horizontal plate 107 is disposed between the first wall plate 100 and the second wall plate 101, and is fixed to the first wall plate 100 and the second wall plate 101 by the horizontal plate fixing screw one 108 and the horizontal plate fixing screw two 109, so as to strengthen the fixation of the magazine main frame A and improve the overall rigidity.

[0049] The base plate 102 is provided with heat sink support holes 132. The heat sink tray B is placed in the heat sink support holes 132 and is used to support the heat sink. According to the outer dimensions of the target heat sink, the first limiting post 103, the second limiting post 104, the third limiting post 105, and the fourth limiting post 106 are moved and adjusted along the adjustable slides corresponding to each limiting post, so that the four limiting posts form a limiting space that matches the outer dimensions of the target heat sink; then the corresponding limiting post fixing screws are tightened to fix the position of the limiting posts. After the heat sinks are stacked on the heat sink tray B, the cartridge is loaded into the automated mounting equipment; the equipment lifting device lifts the heat sink tray B through the heat sink support holes 132 to lift the heat sink, thereby realizing the subsequent automated pick-up and mounting of the heat sink.

[0050] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
