[0032] 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 drive mechanism 200. The support mechanism 100 is used to carry the heat dissipation sticker, and the drive mechanism 200 is connected to the support mechanism 100 and is used to drive the support mechanism 100 to move.

[0033] The support mechanism 100 includes a support component 110 and a follower component 120 connected to each other. The drive mechanism 200 includes a cam 210 and a first drive member 220. The first drive member 220 is connected to the cam 210 in a transmission manner, and the cam 210 is connected to the follower component 120 in a transmission manner. Under the drive of the first drive member 220, the cam 210 rotates, and the follower component 120 moves along a first direction, which in turn drives the support component 110 to move along the first direction, which is the height direction of the attachment device.

[0034] It should be noted that the first direction is Figures 1 to 3 The X direction shown is the height direction of the attachment device.

[0035] Here, the heat dissipation patch is placed on the support assembly 110. Driven by the first drive member 220, the cam 210 rotates, the transmission follower assembly 120 moves along the first direction, and drives the support assembly 110 to move along the first direction, so as to change the position of the heat dissipation patch on the support assembly 110 in the first 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.

[0036] The aforementioned attachment device, driven by the first driving member 220, drives the support component 110 to rise and fall along the first direction through the cooperation of the cam 210 and the follower component 120, so as to change the height position of the heat dissipation sticker on the support component 110 in the first direction, so that the heat dissipation sticker can be smoothly adhered to the surface of the flip-chip film. By controlling the driving mechanism 200 and the support mechanism 100, the lifting speed and position accuracy of the heat dissipation sticker can be quantitatively controlled, improving the situation where the adhesion effect of the heat dissipation sticker is affected by the inaccurate height position of the heat dissipation sticker. The structure is simple and compact, greatly simplifying the overall structure of the attachment device.

[0037] In the embodiments of this application, the support component 110 is used to support the heat dissipation pad. The support component 110 is connected to the follower component 120, and the support component 110 and the follower component 120 can be connected in various ways, as long as the support component 110 can move along the first direction with the follower component 120. Therefore, the connection method of the support component 110 and the follower component 120 is not limited. The number of support components 110 is not limited to one. When the number of support components 110 is at least two, each support component 110 can be arranged side by side along the same direction to improve space utilization and production efficiency.

[0038] In the embodiments of this application, the cam 210 is connected to the follower component 120 in a transmission manner, that is, the rotation of the cam 210 can drive the follower component 120 to move along a first direction. The cam 210 and the follower component 120 can be directly connected or indirectly connected through other components.

[0039] In the embodiments of this application, the first driving member 220 is connected to the cam 210 in a transmission manner, that is, the rotation of the first driving member 220 can drive the cam 210 to rotate. The first driving member 220 and the cam 210 can be directly connected or indirectly connected through other components. Optionally, the first driving member 220 is a motor or other type of driving component.

[0040] Please refer to Figure 3The attachment device also includes a base 300, and the drive mechanism 200 also includes a transmission assembly 230. The cam 210 is located on one side of the base 300, and the transmission assembly 230 is located on the side of the base 300 away from the cam 210. The first drive member 220 is connected to the cam 210 through the transmission assembly 230.

[0041] It should be noted that the first driving member 220 is connected to the cam 210 through the transmission assembly 230. Under the drive of the first driving member 220, the cam 210 is rotated through the transmission assembly 230, the transmission follower assembly 120 moves along the first direction, and drives the support assembly 110 to move along the first direction.

[0042] Here, the first driving component 220 is connected to the cam 210 via the transmission assembly 230. This can be understood as: the first driving component 220 is connected to the transmission assembly 230, and the transmission assembly 230 is connected to the cam 210. The transmission connection can be a direct connection or an indirect connection.

[0043] In the embodiments of this application, the cam 210 and the transmission assembly 230 are disposed on opposite sides of the base 300. For example, the cam 210 and the transmission assembly 230 can be disposed on opposite sides of the base 300 in the thickness direction, which can improve the space utilization of the base 300 in the thickness direction.

[0044] In the embodiments of this application, the base 300 is a component for assembling parts such as the cam 210 and the transmission assembly 230. The base 300 can have various structural forms, such as an integral structure or a combination of multiple plates. The structure of the base 300 is not specifically limited here.

[0045] For details, please refer to Figure 4 The transmission assembly 230 includes a drive wheel 231, a driven wheel 232, a transmission belt 233, a rotating shaft 234, and a rotating seat 235. The rotating seat 235 is located on the side of the base 300 away from the cam 210. One end of the rotating shaft 234 is fixedly connected to the cam 210, and the other end of the rotating shaft 234 passes through the base 300 and the rotating seat 235 and is fixedly connected to the driven wheel 232. The drive wheel 231 is fixedly connected to the output shaft of the first driving member 220. The transmission belt 233 is sleeved on the drive wheel 231 and the driven wheel 232. Under the drive of the first driving member 220, the drive wheel 231 rotates, which in turn drives the driven wheel 232, the rotating shaft 234, and the cam 210 to rotate.

[0046] Understandably, under the drive of the first drive member 220, the drive wheel 231 rotates, which in turn drives the driven wheel 232, the rotating shaft 234, and the cam 210 to rotate. The rotation of the cam 210 will drive the follower component 120 to move along the first direction, and drive the support component 110 to move along the first direction.

[0047] In the embodiments of this application, both the base 300 and the rotating seat 235 are provided with through holes for the rotating shaft 234 to pass through. The rotating seat 235 is constructed as a block structure, and the outer contour of the block structure can be a cube, cuboid or other shapes.

[0048] In the embodiments of this application, one end of the rotating shaft 234 is fixedly connected to the cam 210, and the other end of the rotating shaft 234 is fixedly connected to the driven wheel 232. The rotating shaft 234 is detachably connected to the cam 210 and the driven wheel 232, for example, the rotating shaft 234 is fixed to the cam 210 and the driven wheel 232 by a plug-in connection, and the rotating shaft 234 is coaxially arranged with the cam 210 and the driven wheel 232. The rotating shaft 234 has a columnar structure, and the outer contour of the columnar structure can be cylindrical or other shapes.

[0049] In the embodiments of this application, the drive wheel 231 and the output shaft of the first drive member 220 are detachably connected. For example, the middle part of the drive wheel 231 is inserted and fixed to the output shaft of the first drive member 220 so that the drive wheel 231 and the output shaft of the first drive member 220 are coaxially arranged.

[0050] In the embodiments of this application, the transmission belt 233 is sleeved on the outside of the driving wheel 231 and the driven wheel 232. The transmission belt 233 can mesh with the driving wheel 231 and the driven wheel 232. For example, the inner side of the transmission belt 233 is provided with a rack, and the driving wheel 231 and the driven wheel 232 are gears, so that the rotation of the driving wheel 231 can drive the driven wheel 232 to rotate.

[0051] For more specific details, please refer to Figure 4 The base 300 includes a base plate 310, a side plate 320 and a first reinforcing plate 330. The side plate 320 is fixed to the top of the base plate 310. The transmission assembly 230 and the cam 210 are respectively disposed on opposite sides of the side plate 320 along its thickness direction. The first reinforcing plate 330 is fixed to the top of the base plate 310 and disposed on the side of the side plate 320 away from the cam 210.

[0052] It should be noted that the thickness direction of the side panel 320 is... Figure 4 The Z direction is shown. Since the side plate 320 is fixed to the top of the base plate 310, and the transmission assembly 230 and the cam 210 are respectively located on opposite sides of the side plate 320 along its thickness direction, the overall structure is compact and the space utilization of the side plate 320 is improved. By setting the first reinforcing plate 330, the side plate 320 can be supported, preventing the side plate 320 from collapsing due to uneven force, which helps to improve the structural stability of the base 300.

[0053] In the embodiments of this application, the base plate 310, the side plate 320 and the first reinforcing plate 330 can be an integral structure with good integrity and high mechanical strength; the base plate 310, the side plate 320 and the first reinforcing plate 330 can also be a separate structure, for example, fixed by screw connection, snap-fit ​​or other means, which is convenient for maintenance and replacement.

[0054] In the embodiments of this application, the side plate 320 is fixed to the top of the base plate 310, and the side plate 320 and the base plate 310 are vertically connected. The first reinforcing plate 330 is vertically connected to the base plate 310 and the side plate 320 respectively. The base plate 310, the side plate 320 and the first reinforcing plate 330 are all constructed as plate-like structures, and the outer contour of the plate-like structure can be rectangular, circular or elliptical, etc.

[0055] In the embodiments of this application, reference is made to Figure 1 The attachment device also includes a protective cover 400, which covers the side plate 320 on the side opposite to the cam 210, so that the side plate 320 and the first reinforcing plate 330 can be protected by the protective cover 400 to avoid corrosion or contamination from the external environment.

[0056] Please refer to Figure 3 and Figure 4 The follower assembly 120 includes a follower 121, an elastic member 122, and a follower seat 123. The support assembly 110 is fixed to the follower seat 123. The follower seat 123 is movably disposed on the side of the side plate 320 away from the transmission assembly 230. The follower 121 is fixed to the side of the follower seat 123 facing the side plate 320, and the follower 121 is connected to the cam 210 for transmission. The elastic member 122 elastically abuts against the base plate 310 and the follower seat 123. Under the drive of the first drive member 220, the cam 210 rotates, which can drive the follower 121 to move along the first direction.

[0057] Understandably, driven by the first driving member 220, the driving wheel 231 rotates, which in turn drives the driven wheel 232, the rotating shaft 234, and the cam 210 to rotate. The transmission follower 121 moves along the first direction, which in turn drives the follower seat 123 to move along the first direction, and drives the support assembly 110 to move along the first direction. The elastic member 122 is always in a downward-stretched state to pull the entire follower assembly 120 downward, ensuring that the follower 121 remains firmly against the contour surface of the cam 210.

[0058] In the embodiments of this application, the follower 121 is a cam follower, whose working principle is to force the follower seat 123 to move in a plane perpendicular to the axis of the cam 210 through the contour line of the cam 210. This movement can be linear or curvilinear, depending on the contour shape of the cam 210. Optionally, refer to Figure 4Furthermore, a sensing sheet 126 and a photoelectric sensor 127 can be set to determine the moving position of the follower 121. For example, three photoelectric sensors 127 can be set and distributed side by side along the first direction. Two of the photoelectric sensors 127 can determine whether the moving position of the follower 121 has reached the upper or lower limit position, and the other photoelectric sensor 127 can determine whether the moving position of the follower 121 is at the starting position.

[0059] In the embodiments of this application, the elastic element 122 is a tension spring, and the number of elastic elements 122 is not limited to one, that is, at least two elastic elements 122 can be provided between the base plate 310 and the follower seat 123.

[0060] In the embodiments of this application, the support component 110 is fixed to the follower seat 123, and the follower seat 123 is movably disposed on the side of the side plate 320 away from the transmission component 230. The follower seat 123 can be in various structural forms, such as an integral structure or composed of multiple plates. The structure of the follower seat 123 is not specifically limited here.

[0061] Further, please refer to Figure 3 The follower assembly 120 also includes a first slider 124 and a first guide rail 125. The first guide rail 125 is fixed to the side of the side plate 320 away from the transmission assembly 230. The first slider 124 is slidably disposed on the first guide rail 125 along the first direction. The follower seat 123 is fixed to the side of the first slider 124 away from the first guide rail 125.

[0062] Here, when the follower seat 123 moves along the first direction, due to the setting of the first guide rail 125, the first slider 124 can also move along the first direction with the follower seat 123 to guide the movement of the follower seat 123 in the first direction.

[0063] In the embodiments of this application, the follower seat 123 and the first slider 124 can be detachably connected or non-detachably connected. The first slider 124 is constructed as a block structure, and the outer contour of the block structure can be a cube, cuboid, or other shapes.

[0064] In the embodiments of this application, the first guide rail 125 and the side plate 320 can be detachably connected or non-detachably connected. The number of first guide rails 125 is not limited to one; for example, the number of first guide rails 125 is at least two. Each first guide rail 125 is distributed at intervals on both sides of the cam 210, and correspondingly, the first guide rail 125 and the first slider 124 are arranged in a one-to-one correspondence.

[0065] Furthermore, please refer to Figure 3The follower seat 123 includes a vertical plate 123a, a horizontal plate 123b, and a second reinforcing plate 123c. The vertical plate 123a is fixed to the side of the first slider 124 away from the first guide rail 125. The horizontal plate 123b is fixed to the top of the vertical plate 123a. The second reinforcing plate 123c is fixed to the bottom of the horizontal plate 123b and is located on the side of the vertical plate 123a away from the cam 210.

[0066] It should be noted that the upright plate 123a is fixed to the side of the first slider 124 away from the first guide rail 125. By setting the second reinforcing plate 123c, the upright plate 123a can be supported by the second reinforcing plate 123c, preventing the upright plate 123a from collapsing due to uneven force, making the overall structure compact and improving the space utilization of the upright plate 123a.

[0067] In the embodiments of this application, the vertical plate 123a, the horizontal plate 123b and the second reinforcing plate 123c can be an integral structure with good integrity and high mechanical strength; the vertical plate 123a, the horizontal plate 123b and the second reinforcing plate 123c can also be a separate structure, for example, fixed by screw connection, snap-fit ​​or other means, which is convenient for maintenance and replacement.

[0068] In the embodiments of this application, the second reinforcing plate 123c is perpendicularly connected to the vertical plate 123a and the horizontal plate 123b, respectively. The vertical plate 123a, the horizontal plate 123b and the second reinforcing plate 123c are all constructed as plate-like structures, and the outer contour of the plate-like structure can be rectangular, circular or elliptical, etc.

[0069] Please refer to Figure 5 The support assembly 110 includes a fixed base 111, an adjusting plate 112, a connecting plate 113, and a support platform 114. The support platform 114 is fixed to the top of the adjusting plate 112 and is used to support the heat dissipation pad. The adjusting plate 112 is movably connected to the connecting plate 113 and is used to finely adjust the horizontal position of the support platform 114. The connecting plate 113 is installed on the fixed base 111, and the fixed base 111 is fixedly connected to the horizontal plate 123b.

[0070] It is understandable that the support platform 114 is installed on the fixed base 111 via the adjustment plate 112 and the connecting plate 113. The fixed base 111 is installed on the horizontal plate 123b of the follower base 123. By adjusting the adjustment plate 112, the horizontal position of the support platform 114 can be finely adjusted so that the support platform 114 remains horizontal, thereby avoiding the instability of the support platform 114 from affecting the subsequent application of the heat dissipation sticker.

[0071] In the embodiments of this application, the support platform 114 is fixed to the top of the adjusting plate 112. The support platform 114 and the adjusting plate 112 can be detachably connected, for example, by screwing or plugging. Alternatively, the support platform 114 and the adjusting plate 112 can be non-detachably connected, for example, by riveting or welding. The support platform 114 is provided with adsorption holes for adsorbing and fixing the heat dissipation patch. The adsorption holes are connected to an external vacuum device. The external vacuum device creates a vacuum, generating negative pressure within the adsorption holes to fix the heat dissipation patch to the support platform 114.

[0072] In the embodiments of this application, the adjusting plate 112 and the connecting plate 113 can be detachably connected, for example, by screws. The adjusting plate 112 can be finely adjusted by adjusting the screws, thereby adjusting the horizontal position of the support platform 114.

[0073] In the embodiments of this application, the connection between the connecting plate 113 and the fixing base 111, and the connection between the fixing base 111 and the horizontal plate 123b, can be either detachable or non-detachable.

[0074] In the embodiments of this application, the fixing base 111, the adjusting plate 112, and the connecting plate 113 are constructed as plate-like structures, and the outer contour of the plate-like structure can be a cube, a cuboid, or other shapes.

[0075] For details, please refer to Figure 5 The support assembly 110 also includes a second driving member, a second slider 115 and a second guide rail 116. The second guide rail 116 is fixed to the top of the fixed base 111. The second slider 115 slides along the second direction on the second guide rail 116 and is fixedly connected to the connecting plate 113. The second driving member is used to drive the second slider 115 to move along the second direction. The second direction intersects with the first direction but is not coplanar.

[0076] It should be noted that the second direction is Figure 5 The Y direction is shown. Under the drive of the second driving member, the second slider 115 moves along the second direction, which can drive the connecting plate 113 and the support platform 114 to move along the second direction.

[0077] In embodiments of this application, the second driving member is connected to the second slider 115, which is constructed as a block structure. The outer contour of the block structure can be a cube, cuboid, or other shape. Optionally, the second driving member is a motor or other type of driving component.

[0078] Please refer to Figure 5 The support assembly 110 also includes a scale extending in the second direction, which is fixed to the mounting base 111 and used to identify the position of the support platform 114 in the second direction.

[0079] Here, since the support platform 114 can move along the second direction, the position of the support platform 114 in the second direction can be quickly identified by setting a scale.

[0080] In the embodiments of this application, the ruler can be a ruler label paper, which can be adhered to the fixing base 111; or, the ruler can be directly engraved on the fixing base 111 with a carving knife.

[0081] For more specific details, please refer to Figure 5 The support assembly 110 also includes a positioning plate 118 and a locking handle 119. One end of the positioning plate 118 is fixedly connected to the connecting plate 113, and the other end of the positioning plate 118 is locked or unlocked to the fixed seat 111 via the locking handle 119.

[0082] It is understandable that, since the support platform 114 is fixed to the connecting plate 113, and the support platform 114 and the connecting plate 113 can move in the second direction, after the support platform 114 and the connecting plate 113 move to the set position, the connecting plate 113 can be locked by the locking handle 119 so that the support platform 114 and the connecting plate 113 are fixed in place; if the support platform 114 and the connecting plate 113 need to be moved again in the future, the connecting plate 113 can be unlocked by the locking handle 119.

[0083] In the embodiments of this application, both the positioning plate 118 and the fixing base 111 are provided with locking holes, and the locking handle 119 can pass through and be threaded into the locking hole.

[0084] In the embodiments of this application, the positioning plate 118 is constructed as an L-shaped plate structure. The positioning plate 118 includes a first part and a second part that are vertically connected. The first part is fixedly connected to the connecting plate 113, and the second part is locked or unlocked to the fixing seat 111 by a locking handle 119. In other embodiments, the positioning plate 118 may also be a plate structure of other shapes.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
