[0031] Please refer to Figures 1 to 3 In one embodiment, the attachment device is used to attach a heat dissipation sticker to the surface of a flip-chip film. The attachment device includes a support mechanism 100 and a lifting mechanism 200. The support mechanism 100 is used to carry the heat dissipation sticker, and the lifting mechanism 200 is connected to the support mechanism 100 and is used to drive the support mechanism 100 to move.

[0032] The lifting mechanism 200 includes a lifting drive 210 and a lifting assembly 220. The lifting assembly 220 is fixedly connected to the support mechanism 100 and the lifting drive 210 respectively. Under the drive of the lifting drive 210, the lifting assembly 220 moves along a third direction and drives the support mechanism 100 to move along a third direction, which is the height direction of the attachment device.

[0033] It should be noted that the third party is... Figures 1 to 3 The Z direction shown is the height direction of the attachment device.

[0034] Here, the heat dissipation patch is placed on the support mechanism 100. Driven by the lifting drive component 210, the lifting component 220 moves along the third direction, causing the support mechanism 100 to move along the third direction, so as to change the position of the heat dissipation patch on the support mechanism 100 in the third direction, so that the heat dissipation patch can be smoothly adhered to the surface of the flip-chip film, and the heat generated by the flip-chip film can be quickly conducted and dissipated through the heat dissipation patch.

[0035] The aforementioned bonding device, driven by the lifting drive 210, moves the lifting assembly 220 along a third direction, thereby moving the support mechanism 100 along a third direction to change the position of the heat dissipation sticker on the support mechanism 100 in the third direction, so that the heat dissipation sticker can be smoothly adhered to the surface of the flip-chip film. By controlling the lifting drive 210 and the support mechanism 100, the lifting speed and position accuracy of the heat dissipation sticker can be quantitatively controlled, improving the bonding effect of the heat dissipation sticker due to inaccurate height position. The structure is simple and compact, greatly simplifying the overall structure of the bonding device.

[0036] In the embodiments of this application, the support mechanism 100 is used to support the heat dissipation pad. The support mechanism 100 is fixedly connected to the lifting component 220. The support mechanism 100 and the lifting component 220 can be connected in various ways, as long as the support mechanism 100 can move along a third direction with the lifting component 220. The connection method between the support mechanism 100 and the lifting component 220 is not limited here. The number of support mechanisms 100 is not limited to one. When the number of support mechanisms 100 is at least two, each support mechanism 100 can be arranged side by side in the same direction to improve space utilization and production efficiency.

[0037] In the embodiments of this application, the lifting drive component 210 is fixedly connected to the lifting assembly 220. The lifting drive component 210 and the lifting assembly 220 can be directly connected or indirectly connected through other components. Optionally, the lifting drive component 210 is a motor or other type of drive component.

[0038] Please refer to Figure 2 The attachment device also includes an installation platform 300, and the lifting assembly 220 includes a fixed seat 221 and a lifting seat 222. The support mechanism 100 is located on the top side of the lifting seat 222, the lifting drive component 210 is fixedly connected to the bottom side of the lifting seat 222, the periphery of the lifting seat 222 is slidably connected to the fixed seat 221, and the fixed seat 221 is fixed to the installation platform 300.

[0039] Understandably, driven by the lifting drive component 210, the lifting seat 222 slides relative to the fixed seat 221 in a third direction, thereby moving the support mechanism 100 in the third direction, while the fixed seat 221 remains stationary. Through this arrangement, the support mechanism 100, the lifting drive component 210, and the fixed seat 221 are connected to different sides of the lifting seat 222, making the structure of the lifting assembly 220 more compact and improving the space utilization of the lifting seat 222.

[0040] In the embodiments of this application, the support mechanism 100 is detachably fixed to the top side of the lifting seat 222. For example, the top sides of the support mechanism 100 and the lifting seat 222 are respectively provided with fixing holes, and fasteners such as screws are passed through the fixing holes of the support mechanism 100 and the lifting seat 222 to fix the two together.

[0041] In the embodiments of this application, the lifting drive 210 is detachably fixed to the bottom side of the lifting seat 222. For example, the bottom side of the lifting seat 222 is provided with a threaded hole, and the output shaft of the lifting drive 210 is provided with an external thread. The external thread is screwed into the threaded hole so that the lifting drive 210 is fixedly connected to the lifting seat 222.

[0042] In the embodiments of this application, the fixing base 221 is detachably fixed to the mounting platform 300. For example, fixing holes are provided on the fixing base 221 and the mounting platform 300 respectively. Fasteners such as screws are passed through the fixing holes of the fixing base 221 and the mounting platform 300 to fix the two together.

[0043] In the embodiments of this application, the attachment device further includes a protective cover 400, which covers one side of the fixed base 221 so that the fixed base 221 and the lifting base 222 can be protected by the protective cover 400 to avoid corrosion or contamination from the external environment.

[0044] For details, please refer to Figure 3 The lifting seat 222 includes a top plate 222a, two side plates 222b and a connecting block 222c. The two side plates 222b are spaced apart along a first direction. The top plate 222a is located on the top side of the two side plates 222b. The support mechanism 100 is fixedly connected to the top side of the top plate 222a. The lifting drive component 210 is fixedly connected to the bottom side of the top plate 222a through the connecting block 222c. The first direction intersects with the third direction but is not coplanar.

[0045] It should be noted that the first direction is Figure 3 The X direction shown is the length direction of the attachment device. The top plate 222a spans the top side of the two side plates 222b. The support mechanism 100 and the lifting drive mechanism are respectively located on opposite sides of the top plate 222a along its thickness direction. This can improve the space utilization of the top plate 222a and make the structure of the lifting assembly 220 more compact.

[0046] In the embodiments of this application, the top plate 222a and the two side plates 222b are vertically arranged. The top plate 222a and the two side plates 222b can be a separate structure or an integral structure. The top plate 222a and the two side plates 222b are all constructed as plate-like structures, and the outer contour of the plate-like structure includes rectangles, circles or other shapes.

[0047] In the embodiments of this application, the connecting block 222c is fixedly connected to the lifting drive component 210 and the top plate 222a respectively, which can be a detachable fixation or a non-detachable fixation. The connecting block 222c is constructed as a block structure, and the outer contour of the block structure includes a rectangular block, a circular block, or other shapes.

[0048] For more specific details, please refer to Figure 3 The lifting assembly 220 also includes a lifting guide rail 223 and a lifting slider 224. The lifting slider 224 is slidably disposed on the lifting guide rail 223 along a third direction. The lifting guide rail 223 is fixed to the periphery of the lifting seat 222, and the lifting slider 224 is fixed to the fixed seat 221.

[0049] Understandably, driven by the lifting drive component 210, the lifting seat 222 slides relative to the fixed seat 221 in a third direction. At this time, the lifting guide rail 223 slides relative to the lifting slider 224 in a third direction to guide the movement of the lifting seat 222 in the third direction and prevent the position of the lifting seat 222 from shifting during the movement.

[0050] In the embodiments of this application, the number of lifting guide rails 223 and lifting sliders 224 is not limited to one; that is, the number of lifting guide rails 223 and lifting sliders 224 can both be at least two. For example, the lifting seat 222 along... Figure 1 At least one lifting guide rail 223 is provided on each of the opposite sides in the X direction, and at least one lifting slider 224 is provided on each lifting guide rail 223, so that the two sides of the fixed base 221 are slidably connected to the lifting base 222 along the X direction. Figure 3 The two opposite sides in the X direction shown.

[0051] In the embodiments of this application, the lifting guide rail 223 and the lifting seat 222 are fixedly connected. The connection between the two can be detachable or non-detachable. For example, the lifting guide rail 223 and the lifting seat 222 are respectively provided with fixing holes, and fasteners such as screws are passed through the fixing holes of the lifting guide rail 223 and the lifting seat 222 to fix the two together.

[0052] In the embodiments of this application, the lifting slider 224 and the fixed base 221 are fixedly connected. The connection between the two can be detachable or non-detachable. For example, the lifting slider 224 and the fixed base 221 are respectively provided with fixing holes, and fasteners such as screws are passed through the fixing holes of the lifting slider 224 and the fixed base 221 to fix the two together.

[0053] In the embodiments of this application, reference is made to Figure 3 Alternatively, photoelectric sensors 225 can be set to determine the moving position of the lifting slider 224. For example, three photoelectric sensors 225 can be set and distributed side by side along a third direction. Two of the photoelectric sensors 225 can determine whether the moving position of the lifting slider 224 has reached the upper or lower limit position, and the other photoelectric sensor 225 can determine whether the moving position of the lifting slider 224 is at the starting position.

[0054] For a specific embodiment, please refer to Figure 3 The mounting base 221 includes a mounting plate 221a and two support plates 221b. The two support plates 221b are fixed to the mounting platform 300 and are spaced apart along the first direction. The mounting plate 221a spans between the two support plates 221b. The first direction intersects with the third direction but is not coplanar.

[0055] It should be noted that the two support plates 221b are fixed to the mounting platform 300 and along... Figure 3 As shown, the mounting plate 221a is spaced apart in the X direction and spans between the two support plates 221b, which makes the structure of the fixing base 221 compact.

[0056] In the embodiments of this application, the mounting plate 221a is located in the middle of the height position of the two support plates 221b, that is, the mounting plate 221a spans between the two support plates 221b, and the mounting plate 221a and the two support plates 221b form an H-shaped structure, so that there is installation space above and below the mounting plate 221a, which can reserve enough space for the installation of other components.

[0057] In the embodiments of this application, the mounting plate 221a and the two support plates 221b can be either separate structures or integrated structures. The mounting plate 221a and the two support plates 221b are all constructed as plate-like structures, and the outer contour of the plate-like structure includes rectangular, circular, or other shapes.

[0058] In the embodiments of this application, the support plate 221b is fixed to the mounting platform 300, which can be a detachable fixation or a non-detachable fixation.

[0059] For a specific embodiment, please refer to Figure 3 The lifting drive component 210 includes a drive part 211 and an extension rod 212. The drive part 211 is fixed to the mounting plate 221a. The mounting plate 221a has a first clearance hole 221c for the extension rod 212 to pass through. After the extension rod 212 passes through the first clearance hole 221c, it is fixedly connected to the lifting seat 222.

[0060] Understandably, driven by the drive unit 211, the extension rod 212 moves in a third direction, causing the lifting seat 222 to move in a third direction, and causing the support mechanism 100 to move in a third direction.

[0061] In the embodiments of this application, the drive unit 211 and the mounting plate 221a are detachably connected. The drive unit 211 and the mounting plate 221a are each provided with fixing holes. Screws or other fasteners are passed through these fixing holes to secure the connection. Optionally, the lifting drive component 210 is a lead screw motor.

[0062] In the embodiments of this application, the diameter of the first clearance hole 221c is greater than or equal to the outer diameter of the extension rod 212, so that the extension rod 212 can pass smoothly through the first clearance hole 221c. The first clearance hole 221c can be a round hole, a square hole, or other shapes, and the shape of the first clearance hole 221c is not limited here.

[0063] Please refer to Figure 3 and Figure 2The mounting platform 300 includes a substrate 310, a first translation component 320 and a second translation component 330. A fixing seat 221 is fixed to the first translation component 320. The first translation component 320 is disposed on the second translation component and can drive the fixing seat 221 to move along a first direction. The second translation component 330 is disposed on the substrate 310 and can drive the fixing seat 221 to move along a second direction. The first direction, the second direction and the third direction intersect each other and are not coplanar.

[0064] Here, the first direction is Figure 3 The X direction is shown, and the second direction is... Figure 3 The Y direction is shown. The first translation component 320 can drive the support mechanism 100 to move along the first direction, and the second translation component 330 can drive the support mechanism 100 to move along the second direction. That is, the support mechanism 100 can move in the first direction, the second direction and the third direction, which can more flexibly change the position of the support mechanism 100, so that the position adjustment of the heat dissipation pad on the support mechanism 100 is more flexible.

[0065] In the embodiments of this application, the substrate 310 is a component for mounting the second translation component 330 or other components. The substrate 310 is constructed as a plate-like structure, and the outer contour of the plate-like structure includes a rectangle, a circle or other shapes.

[0066] In the embodiments of this application, the second translation component 330 is a component that can drive the fixed base 221 to move along the second direction. For example, the second translation component 330 includes a second guide rail and a second sliding plate. The second guide rail is fixed to the base plate 310, and the second sliding plate is slidably disposed on the second guide rail and connected to the first translation component 320, so that when the second sliding plate slides relative to the second guide rail, it can drive the first translation component 320 and the fixed base 221 to move.

[0067] For details, please refer to Figure 3 The first translation component 320 includes a first sliding plate 321, a first guide rail 322, a positioning plate 323, and a locking handle 324. The first guide rail 322 is fixed to the second translation component 330. The first sliding plate 321 slides along the first direction on the first guide rail 322 and is fixedly connected to the fixed base 221. One end of the positioning plate 323 is fixedly connected to the first sliding plate 321, and the other end of the positioning plate 323 is locked or unlocked to the second translation component 330 through the locking handle 324.

[0068] Understandably, the first sliding plate 321 can move relative to the first guide rail 322 along the first direction. Since the fixing seat 221 and the positioning plate 323 are fixed to the first sliding plate 321, the fixing seat 221 and the positioning plate 323 can move with the first sliding plate 321 along the first direction. After the first sliding plate 321 moves to the set position, the locking handle 324 can lock the positioning plate 323 to fix the first sliding plate 321 in place. If the first sliding plate 321 needs to be moved again later, the locking handle 324 can unlock the positioning plate 323.

[0069] In an embodiment of this application, the first sliding plate 321 has a second clearance hole through which the extension rod 212 passes. The diameter of the second clearance hole is greater than or equal to the outer diameter of the extension rod 212 so that the extension rod 212 can pass smoothly through the second clearance hole. The second clearance hole can be a round hole, a square hole or other shapes, and the shape of the second clearance hole is not limited here.

[0070] In the embodiments of this application, both the positioning plate 323 and the second translation component 330 are provided with locking holes, and the locking handle 324 can pass through and be threaded into the locking hole.

[0071] In embodiments of this application, the positioning plate 323 is constructed as an L-shaped plate structure. The positioning plate 323 includes a first part and a second part that are vertically connected. The first part is fixedly connected to the first sliding plate 321, and the second part is locked or unlocked to the second translation component 330 via a locking handle 324. In other embodiments, the positioning plate 323 may also be a plate structure of other shapes.

[0072] For more specific details, please refer to Figure 4 and Figure 3 The first translation component 320 also includes a telescopic ruler 325 and an elastic member 326. One end of the elastic member 326 is connected to the second translation component 330, and the other end of the elastic member 326 is connected to the first sliding plate 321. The telescopic ruler 325 is mounted on the base plate 310 and faces the other end of the elastic member 326. The telescopic ruler 325 can extend and retract along the first direction and push against the other end of the elastic member 326 to finely adjust the position of the first sliding plate 321 in the first direction.

[0073] It should be noted that the first sliding plate 321 can move relative to the first guide rail 322 along the first direction. By adjusting the extension length of the telescopic ruler 325 in the first direction, the telescopic ruler 325 can push against the other end of the elastic member 326, so that the elastic member 326 can extend and retract to different degrees, thereby fine-tuning the position of the first sliding plate 321 in the first direction.

[0074] In the embodiments of this application, the telescopic ruler 325 is a micrometer, and the elastic element 326 is a tension spring. The number of elastic elements 326 is not limited to one; that is, the number of elastic elements 326 can be at least two.

[0075] Please refer to Figure 5 The support mechanism 100 includes an adjustment plate 110, a connecting plate 120, and a support platform 130. The support platform 130 is fixed to the top of the connecting plate 120 and is used to support the heat dissipation pad. The connecting plate 120 is movably connected to the top side of the adjustment plate 110. The adjustment plate 110 is installed on the lifting seat 222 and can finely adjust the horizontal position of the support platform 130.
