Description

Technical Field

[0001] This application relates to the field of chip implantation technology, and in particular to a bidirectional oscillating device for chip implantation. Background Technology

[0002] The chip manufacturing process involves a ball-mounting process, which involves arranging solder balls on the chip's pads for subsequent soldering.

[0003] When performing chip ball placement, the chip has a large number of solder ball placement locations, requiring high precision. Current technology utilizes a wobbling mechanism to achieve precise batch placement of solder balls. Typically, ball placement equipment uses a perforated die with through holes aligned with the solder ball placement points. In operation, the die is placed over the chip, and solder balls are placed in batches on top of the die. The chip is connected to a wobbling mechanism, which wobbles left and right, causing the solder balls to pass through the through holes and land at the chip's soldering points.

[0004] Existing shaking mechanisms typically involve a motor driving a fixture to sway left and right. The fixture is connected to the aforementioned perforated plate and chip. This shaking method has the problem that solder balls are not easy to fall into certain holes, thus requiring manual intervention and resulting in low ball placement efficiency. Utility Model Content

[0005] One objective of this invention is to provide a bidirectional swinging device for ball planting, which can improve ball planting efficiency.

[0006] Another objective of this invention is to further enhance the swing effect and improve the ball planting efficiency.

[0007] Another objective of this invention is to improve the versatility and flexibility of the ball-planting mechanism.

[0008] An embodiment of this utility model provides a bidirectional swinging device for planting balls, comprising:

[0009] Base;

[0010] The first swing seat is rotatably connected to the base via a first rotating shaft, and the first rotating shaft is horizontally positioned.

[0011] The first driving mechanism is used to drive the first swing seat to rotate around the axis of the first rotating shaft within a first preset angle range;

[0012] The second swing seat is rotatably connected to the first swing seat via a second rotating shaft. The second rotating shaft is horizontally arranged and not parallel to the first rotating shaft. The second swing seat is used to place a chip fixture loaded with chips to be implanted.

[0013] The second drive mechanism is used to drive the second swing seat to rotate around the second rotating shaft within a second preset angle range.

[0014] Optionally, both the first drive mechanism and the second drive mechanism include:

[0015] A drive motor, including an output shaft for outputting torque;

[0016] The rotating disk rotates synchronously with the output shaft;

[0017] The joystick has two ends hinged to the rotating disk and the target swing seat, respectively, and the two hinge axes of the joystick and the output shaft are arranged parallel to the target rotation axis.

[0018] The target swing seat and the target rotating shaft of the first driving mechanism are respectively the first swing seat and the first rotating shaft, and the target swing seat and the target rotating shaft of the second driving mechanism are respectively the second swing seat and the second rotating shaft.

[0019] Optionally, the rotating disk is provided with a plurality of first mounting holes arranged around the axis of the output shaft, and the rotating disk and the rocker arm are hinged together by a first hinge shaft, the first hinge shaft passing through one of the first mounting holes.

[0020] Optionally, the ball-planting bidirectional swing device further includes a turntable mounting base fixed to the base and the first swing seat, the turntable mounting base being provided with a second mounting hole;

[0021] The rotating disk includes a rotating shaft and a disc. The rotating shaft is rotatably disposed in the second mounting hole, and the disc is hinged to the rocker arm.

[0022] Optionally, the second swing seat is provided with an upward-facing first limiting groove for accommodating the support leg of the chip fixture;

[0023] The ball-planting bidirectional swing device also includes a locking mechanism, one end of which extends into the first limiting groove to clamp the chip fixture in the first horizontal direction.

[0024] Optionally, the bidirectional ball-planting swing device further includes two locking mechanisms that are fixedly disposed on the second swing seat. The two locking mechanisms are located on both sides of the chip fixture in the second horizontal direction. The locking mechanism is provided with a second limiting groove with an upward opening. The second limiting groove is used to insert a locking block on the ball-planting fixture. The ball-planting fixture is provided with a perforated plate mold for allowing solder balls to fall.

[0025] Optionally, the first axis and the second axis are perpendicular to each other.

[0026] Optionally, the first drive mechanism and the second drive mechanism operate synchronously.

[0027] According to one aspect of this utility model, the bidirectional oscillating device for ball placement can realize the oscillation of the chip fixture in two directions. The oscillation in the two directions is oscillation around the first rotating axis and the second rotating axis, rather than linear reciprocating movement. Therefore, the oscillation amplitude is large, which can enable a batch of solder balls to fall quickly into the various solder ball setting points of the chip to be placed on the chip fixture, saving the time of the solder balls automatically rolling into the holes of the perforated plate mold, and effectively improving the ball placement efficiency.

[0028] Furthermore, the first and second drive mechanisms, driven by the drive motor, enable the first and second swing seats to reciprocate, enhancing the swing effect and further improving the ball planting efficiency.

[0029] Furthermore, by setting a snap-fit ​​mechanism on the second swing seat, it is possible to connect with external ball-planting fixtures. Therefore, it is easy to adapt to different ball-planting fixtures (with hole plate molds fixed to different chips). For example, according to the current chip type, the corresponding ball-planting fixture can be plugged in, or the ball-planting fixture can first fix the corresponding hole plate mold and then plug it into the second swing seat, thereby improving the versatility and flexibility of the ball-planting mechanism.

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0035] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0036] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can be implemented without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the spirit of this disclosure.

[0037] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article indicates that the preceding and following related objects have an "or" relationship.

[0038] In this embodiment of the invention, "multiple" refers to two or more. The descriptions of "first," "second," etc., appearing in this embodiment of the invention are for illustrative purposes and to distinguish the objects being described; they do not indicate any order and do not represent a specific limitation on the number of items in this embodiment of the invention, nor do they constitute any limitation on this embodiment of the invention.

[0039] Figure 1 This is a schematic diagram of the assembly structure of the ball-planting bidirectional swing device 100 and the chip fixture 200 according to an embodiment of the present invention. Figure 1As shown, in one embodiment, the bidirectional swing device 100 for chip implantation includes a base 10, a first swing seat 20, a first drive mechanism 30, a second swing seat 40, and a second drive mechanism 50. The first swing seat 20 is rotatably connected to the base 10 via a first rotating shaft 21, which is horizontally positioned. The first drive mechanism 30 drives the first swing seat 20 to rotate around the axis of the first rotating shaft 21 within a first preset angle range. The second swing seat 40 is rotatably connected to the first swing seat 20 via a second rotating shaft 41, which is horizontally positioned and not parallel to the first rotating shaft 21. The second swing seat 40 is used to place a chip fixture 200 loaded with chips to be implanted. The second drive mechanism 50 drives the second swing seat 40 to rotate around the second rotating shaft 41 within a second preset angle range. The first preset angle range and the second preset angle range may be the same or different, and are not limited here. In this embodiment, the first rotating shaft 21 and the second rotating shaft 41 are perpendicular. In other embodiments not shown, the first rotating shaft 21 and the second rotating shaft 41 may be arranged at a certain angle, and are not limited here. In this embodiment, the first driving mechanism 30 and the second driving mechanism 50 can operate simultaneously or sequentially according to a certain time order; no restriction is placed here. The chip fixture 200 can also be equipped with a via mold, with the holes on the via mold aligned with the solder ball placement points on the chip to be plated. Alternatively, the via mold can be mounted on another fixture, which, when connected to the chip fixture 200, aligns the holes on the via mold with the solder ball placement points on the chip to be plated.

[0040] The bidirectional oscillation device 100 for ball placement in this application enables the chip fixture 200 to oscillate in two directions. The oscillation in the two directions is around the first rotating axis 21 and the second rotating axis 41, rather than a linear reciprocating movement. Therefore, the oscillation amplitude is large, which enables a batch of solder balls to fall quickly into the various solder ball setting points of the chip to be placed on the chip fixture 200. This saves the time for the solder balls to automatically roll into the holes of the perforated die and can effectively improve the ball placement efficiency.

[0041] like Figure 1As shown, in one embodiment, both the first drive mechanism 30 and the second drive mechanism 50 include a drive motor 31, a rotating disk 32, and a rocker arm 33. The drive motor 31 includes an output shaft for outputting torque. The rotating disk 32 rotates synchronously with the output shaft, for example, via a spline connection. The two ends of the rocker arm 33 are respectively hinged to the rotating disk 32 and the target swing seat, and the two hinge shafts and the output shaft of the rocker arm 33 are arranged parallel to the target rotating shaft. The target swing seat and the target rotating shaft of the first drive mechanism 30 are the first swing seat 20 and the first rotating shaft 21, respectively, and the target swing seat and the target rotating shaft of the second drive mechanism 50 are the second swing seat 40 and the second rotating shaft 41, respectively. Taking the first drive mechanism 30 as an example, one end of the rocker arm 33 is hinged to the rotating disk 32 via the first hinge shaft 34, and the other end is hinged to the first swing seat 20 via the second hinge shaft 35.

[0042] Furthermore, the rotating disk 32 includes a rotating shaft portion 321 and a disk portion 322. The disk portion 322 is provided with a plurality of first mounting holes 301 arranged around the axis of the output shaft, and the first hinge shaft 34 passes through one of the first mounting holes 301. The ball-planting bidirectional swing device 100 also includes a turntable mounting base 60 fixed to the base 10 and the first swing seat 20. The turntable mounting base 60 is provided with a second mounting hole, and the rotating shaft portion 321 is rotatably disposed in the second mounting hole. Here, the rotating disk 32 can be a flange.

[0043] In this embodiment, the first drive mechanism 30 and the second drive mechanism 50 can realize the reciprocating swing of the first swing seat 20 and the second swing seat 40 under the drive of the drive motor 31, thereby enhancing the swing effect and further improving the ball planting efficiency.

[0044] Furthermore, the rotary disk 32 here can use existing flanges, eliminating the need for custom machining of non-standard parts, which helps save costs.

[0045] Figure 2 This is a schematic diagram of the structure of a bidirectional ball-planting swing device 100 according to an embodiment of the present invention. In one embodiment, as... Figure 2 As shown, the second swing seat 40 is provided with an upward-facing first limiting groove 42 for accommodating the support leg 210 of the chip fixture 200 (see...). Figure 1The bidirectional ball-planting swing device 100 also includes a locking mechanism 70, one end of which extends into the first limiting groove 42 for clamping the chip fixture 200 in the first horizontal direction. In this embodiment, the locking mechanism 70 includes a screw 71 and a handle 72 connected to the screw 71. The screw 71 is threaded into the threaded hole of the second swing seat 40 and can extend into the first limiting groove 42. Rotating the handle 72 can move the screw 71, thereby pressing it into the chip fixture 200. Here, in order to facilitate the assembly of the chip fixture 200 into the first limiting groove 42, the size of the first limiting groove 42 in the first horizontal direction can be set to be slightly larger than the size of the support leg 210 of the chip fixture 200 in the first horizontal direction, and then locked by the locking mechanism 70.

[0046] In a further embodiment, the bidirectional ball-mounting swing device 100 further includes two locking mechanisms 80 respectively fixedly disposed on the second swing seat 40. The two locking mechanisms 80 are located on both sides of the chip fixture 200 in the second horizontal direction. In this embodiment, the second horizontal direction is perpendicular to the first horizontal direction. In other embodiments not shown, the number and position of the locking mechanisms 80 can be other, as long as they can serve to connect with the ball-mounting fixture in the vertical direction, and there are no restrictions here. The locking mechanism 80 is provided with a second limiting groove 801 with an upward opening. The second limiting groove 801 is used to insert a locking block on the ball-mounting fixture. The ball-mounting fixture is provided with a perforated plate mold for the solder balls to fall. That is to say, in this embodiment, the perforated plate mold is fixed on the ball-mounting fixture. The ball-mounting fixture can achieve connection with the chip fixture 200 and alignment of the holes on the perforated plate mold with the soldering points of the chip through the cooperation of the locking block and the second limiting groove 801.

[0047] This embodiment enables insertion with external ball-planting fixtures by setting a snap-fit ​​mechanism 80 on the second swing seat 40. Therefore, it can easily adapt to different ball-planting fixtures (with hole plate molds fixed to different chips). For example, according to the current chip type, the corresponding ball-planting fixture can be inserted, or the ball-planting fixture can first fix the corresponding hole plate mold and then insert it into the second swing seat 40, thereby improving the flexibility of ball planting.

[0048] 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.
