Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip packaging technology, specifically to a ceramic suction cup loading and unloading mechanism. Background Technology
[0002] In semiconductor packaging processes, rotary stages, by fixing wafer frames onto a ring-shaped turntable, adapt to various process requirements (such as chip transfer, cleaning, and testing). In the process of transferring chips from a wafer frame with a perforated blue film to a frame without a perforated blue film for testing, ceramic chucks are inserted into the ring-shaped turntable and fixed below the frame without the perforated blue film to provide vacuum adsorption and a stable support surface for the blue film, facilitating subsequent chip transfer with a rolling mechanism. In other processes (such as testing), the ceramic chucks need to be removed to avoid interference with the inspection camera. In traditional solutions, ceramic chucks are usually manually installed using bolts or clips. Frequent disassembly and reassembly increase downtime, and manual operation can easily cause mechanical collisions between the chucks and the ring-shaped turntable due to horizontal alignment deviations, resulting in chuck damage.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0043] Please see Figures 1 to 4 The ceramic suction cup loading and unloading mechanism 100 shown in a preferred embodiment of this application includes a ceramic suction cup 1, a drive assembly 2, and a plane error adjustment assembly 3. The ceramic suction cup 1 has a hollow structure and several vacuum suction holes. Controllable telescopic locking tongues 11 are correspondingly provided on both sides of the ceramic suction cup 1, and guide chamfers 12 are provided on the edge of the ceramic suction cup 1. The locking tongues 11 cooperate with the fixing slots 202 of the annular turntable 201 on the rotary worktable 200 to install and fix the ceramic suction cup 1 within the annular turntable 201. The drive assembly 2 is used to controllably drive the ceramic suction cup 1 to reciprocate vertically. The plane error adjustment assembly 3 is used to drive the ceramic suction cup 1 to reciprocate in two mutually perpendicular directions on the horizontal plane.
[0044] According to the embodiment of this utility model, the ceramic suction cup 1 is driven by the driving component 2 to reciprocate below the annular turntable 201 on the rotary worktable 200. The retractable locking tongues 11 on both sides of the ceramic suction cup 1 cooperate with the fixing slots 202 of the annular turntable 201 to achieve rapid automatic loading and unloading of the ceramic suction cup 1, thereby improving loading and unloading efficiency. The guide chamfer 12 on the edge of the ceramic suction cup 1, in conjunction with the plane error adjustment component 3, enables the ceramic suction cup 1 to move and adjust along the horizontal plane, compensating for the horizontal alignment deviation between the ceramic suction cup 1 and the annular turntable 201, ensuring that the ceramic suction cup 1 is accurately inserted into the annular turntable 201, and avoiding mechanical collision between the ceramic suction cup 1 and the annular turntable 201 that could cause damage.
[0045] The following detailed description uses specific examples:
[0046] Specifically, please see Figure 3 The ceramic suction cup 1 loading and unloading mechanism 100 also includes a tensioning assembly 4 for driving the extension and retraction of the locking tongue 11. The tensioning assembly 4 includes a parallel gripper cylinder 41 and a tensioning slide rail 42. The parallel gripper cylinder 41 is located below the ceramic suction cup 1, and tensioning grippers 43 are correspondingly arranged on the movable ends of both sides of the parallel gripper cylinder 41. The tensioning slide rail 42 is located at the bottom of the ceramic suction cup 1, and a slidable tensioning slider 44 is arranged on the tensioning slide rail 42 and correspondingly connected to the tensioning grippers 43. The locking tongue 11 is arranged on the tensioning slider 44. By driving the tensioning grippers 43 to open and close synchronously through the movable ends of the parallel gripper cylinder 41, a stable clamping force is provided to drive the horizontal extension and retraction of the locking tongue 11, ensuring precise engagement between the locking tongue 11 and the fixed slot 202 on the annular turntable 201, thereby automating the loading and unloading of the ceramic suction cup 1 and improving process switching efficiency.
[0047] Further, please see Figure 3 and Figure 5 The locking tongue 11 has an air inlet 111, and the ceramic suction cup 1 is equipped with a vacuum tube 5. One end of the vacuum tube 5 is connected to the ceramic suction cup 1, and the other end of the vacuum tube 5 passes through the tension / retraction slider 44 and is connected to the air inlet 111. After the locking tongue 11 is fixed in the fixing slot 202 on the annular turntable 201, the ceramic suction cup 1 is connected to the vacuum passage 203 on the rotating worktable 200 through the cooperation of the air inlet 111 on the locking tongue 11 and the vacuum tube 5, thereby realizing the vacuum adsorption function of the ceramic suction cup 1. Specifically, in this embodiment, the vacuum tube 5 is a flexible tube that can adaptively adjust with the movement of the tension / retraction slider 44 and the locking tongue 11 to ensure the adsorption stability of the ceramic suction cup 1.
[0048] Specifically, please see Figure 4 and Figure 5The planar error adjustment assembly 3 includes a fixed base plate 31, a first adjustment plate 32, and a second adjustment plate 33. A first slide rail 34 is provided on the top surface of the fixed base plate 31. A first slider 35, which cooperates with the first slide rail 34, is provided on the bottom surface of the first adjustment plate 32. The first slider 35, in cooperation with the first slide rail 34, drives the first adjustment plate 32 to reciprocate along a first direction. A second slide rail 36, perpendicular to the first slide rail 34, is provided on the top surface of the first adjustment plate 32. A second slider 37, which cooperates with the second slide rail 36, is provided on the bottom surface of the second adjustment plate 33. The second slider 37, in cooperation with the second slide rail 36, drives the second adjustment plate 33 to reciprocate along a second direction perpendicular to the first direction. A parallel gripper cylinder 41 is provided on the top surface of the second adjustment plate 33. The ceramic suction cup 1 has a guide chamfer 12 on its edge. When the ceramic suction cup 1 is inserted into the annular turntable 201 from below, if there is a horizontal alignment deviation between the ceramic suction cup 1 and the annular turntable 201, the annular turntable 201 will be forced to move towards its center position under the action of the guide chamfer 12. At this time, the ceramic suction cup 1 can be moved and adjusted along the horizontal plane by the cooperation of the various structures of the plane error adjustment component 3, so as to compensate for the horizontal alignment deviation between the ceramic suction cup 1 and the annular turntable 201, and make the ceramic suction cup 1 accurately inserted into the annular turntable 201.
[0049] Further, please see Figure 5 The planar error adjustment assembly 3 also includes a first limiting block 38, a first spring plunger 39, a second limiting block 310, and a second spring plunger 311. The first limiting block 38 is located on the side of the fixed base plate 31. The two first spring plungers 39 are located on the side of the first adjusting plate 32 and are respectively positioned on both sides of the first limiting block 38. The first spring plungers 39 cooperate with the first limiting block 38 to elastically limit the first adjusting plate 32. The second limiting block 310 is located on the side of the second adjusting plate 33. The two second spring plungers 311 are located on the side of the first adjusting plate 32 and are respectively positioned on both sides of the second limiting block 310. The second spring plungers 311 cooperate with the second limiting block 310 to elastically limit the second adjusting plate 33. Through the cooperation of the limiting blocks and spring plungers, the adjusting plate can be pushed back to its original position after the external force disappears, maintaining the initial alignment state, facilitating adjustment during the next loading and unloading process of the ceramic suction cup 1. Specifically, there are two first limiting blocks 38 and two second limiting blocks 310, which are respectively set on the symmetrical sides of the fixed base plate 31 and the second adjusting plate 33. There are two sets of first spring plungers 39 and second spring plungers 311, with two spring plungers in each set, and the four sets of spring plungers are respectively arranged around the first adjusting plate 32.
[0050] Specifically, please see Figure 4The drive assembly 2 includes a vertical slide rail 21, a vertical slider 22, a drive motor 23, and a support frame 24. The vertical slider 22 is slidably mounted on the vertical slide rail 21. The drive motor 23 drives the vertical slider 22 to reciprocate along the vertical slide rail 21. The support frame 24 is mounted on the vertical slider 22. The drive assembly 2 drives the ceramic suction cup 1 to reciprocate vertically below the annular turntable 201, thereby enabling the loading and unloading of the ceramic suction cup 1.
[0051] Further, please see Figure 4 and Figure 6 The ceramic suction cup 1 loading and unloading mechanism 100 also includes an overload protection component 6 located below the plane error adjustment component 3. The overload protection component 6 includes a support plate 61, a telescopic rod 62, and a tension spring 63. The support plate 61 is located on the top of the support frame 24, and a linear bearing 64 is mounted on the support plate 61. The telescopic rod 62 is located within the linear bearing 64 and can reciprocate vertically. One end of the telescopic rod 62 is connected to the bottom surface of the fixed base plate 31, and the other end passes through the linear bearing 64 and is connected to a connecting plate 65. The tension spring 63 is located between the support plate 61 and the connecting plate 65. By providing the overload protection component 6, when the horizontal alignment deviation between the ceramic suction cup 1 and the annular turntable 201 is too large, preventing the ceramic suction cup 1 from being inserted into the bottom of the annular turntable 201 for installation, thus causing overload of the loading and unloading mechanism, the fixed base plate 31 is allowed to move downwards relative to the support plate 61, avoiding hard damage to the loading and unloading mechanism. The tension spring 63 can reset the overload protection component 6 after the overload disappears.
[0052] Further, please see Figure 6 A shielding plate 66 is provided on the connecting plate 65, and a slotted photoelectric sensor 67 is provided on the support frame 24. The shielding plate 66 and the slotted photoelectric sensor 67 cooperate to generate a signal alarm. When the loading and unloading mechanism is overloaded, the telescopic rod 62 drives the shielding plate 66 on the connecting plate 65 to move downward, so that the shielding plate 66 enters the detection area of the slotted photoelectric sensor 67 to trigger the alarm signal, which facilitates subsequent processing by the operating system and avoids damage to the mechanism or malfunction.
[0053] 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.
[0054] The embodiments described above are merely illustrative of several implementations of this utility model, 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 utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
