Description

Technical Field

[0001] This utility model belongs to the technical field of motor cooling structure, and in particular relates to a chip extraction device for IC chip plastic packaging. Background Technology

[0002] Molded IC chips (Integrated Circuits) have bonding wires, which are prone to wire collapse defects during the manufacturing process. This is especially true for optocouplers using IR (Infrared Radiation) and PT (Phototransistor) through-beam technology, which are more susceptible to wire collapse during the molding and die-layout process.

[0003] In related technologies, cylinders are used as the driving source to grip the chip. However, during operation, the cylinder is unstable due to factors such as compressed air and cylinder jamming, which is detrimental to the reliable gripping of the chip.

[0004] Therefore, there is an urgent need to design a chip pick-up device for IC chip molding to solve the problem of unstable movement in the above-mentioned cylinder-driven chip pick-up device.

[0005] It should be noted that the information disclosed in this background section is only used to understand the background technology of the present embodiment, and therefore may include information that does not constitute prior art. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Research has revealed that during operation, the cylinder exhibits unstable movement due to factors such as compressed air and cylinder jamming, which hinders reliable chip gripping.

[0035] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.

[0036] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Based on the above research, and referring to Figure 1 This disclosure provides an IC chip encapsulation pick-up device, including: a base 1, a sliding seat 2, a driver 3, a transmission rod 4, and a gripping component 5. The sliding seat 2 is slidably disposed on one side of the base 1, and the gripping component 5 is mounted on the sliding seat 2 so that the sliding seat 2 can drive the gripping component 5 to slide synchronously, thereby driving the gripping component 5 to grip the IC chip.

[0039] Reference Figure 1 To avoid instability during cylinder operation, a driver 3 and a transmission rod 4 are used to drive the sliding seat 2 to slide. In at least one embodiment, a driver 3 is installed on one side of the base 1, and a transmission rod 4 is installed on the movable end of the driver 3. The transmission rod 4 is rotatably connected to the base 1. Specifically, the driver 3 is preferably a servo motor, and the transmission rod 4 is preferably a threaded rod. At the same time, a transmission sleeve 21 is installed on one side of the sliding seat 2. The transmission sleeve 21 is sleeved on the transmission rod 4, and the transmission rod 4 is threadedly connected to the transmission sleeve 21.

[0040] Reference Figure 2 In at least one embodiment, a connecting plate 22 is installed between the sliding seat 2 and the transmission sleeve 21 so that the sliding seat 2 and the transmission sleeve 21 form an integral whole through the connecting plate 22. The cooperation between the sliding seat 2 and the base 1 ensures that the transmission sleeve 21 will not rotate with the rotation of the transmission rod 4, that is, the transmission sleeve 21 can only slide along the axial direction of the transmission rod 4. On the other hand, the sliding of the transmission sleeve 21 along the transmission rod 4 can drive the sliding seat 2 to slide along the base 1.

[0041] Reference Figure 2 In at least one embodiment, to support the transmission rod 4 and ensure that its axial direction remains parallel to the base 1, a guide plate 11 is mounted on the base 1, through which the transmission rod 4 passes. The guide plate 11 supports the end of the transmission rod 4 away from the driver 3, thereby ensuring that the transmission rod 4 remains parallel to the base 1.

[0042] Reference Figure 2In at least one embodiment, a guide rail 12 is provided at one end of the base 1 along the length direction, and the sliding seat 2 is slidably disposed on the guide rail 12 to guide the sliding direction of the sliding seat 2 on the base 1.

[0043] Reference Figure 3 In at least one embodiment, a gripping component 5 is mounted on the sliding seat 2. The gripping component 5 includes a mounting base 51 and two grippers 52 slidably disposed on the mounting base 51. Two sliding grooves are mirror-imagely formed at the end of the mounting base 51 away from the driver 3. The two grippers 52 are slidably disposed within the sliding grooves, and springs 53 are also present within the sliding grooves. The two ends of the springs 53 are fixed to the sidewalls of the sliding grooves and the sidewalls of the grippers 52, respectively, and the length direction of the springs 53 is consistent with the sliding direction of the grippers 52. With this configuration, under normal conditions, the springs 53 can push the two grippers 52 towards the center.

[0044] Reference Figure 2 In at least one embodiment, a power component 23 and a linkage guide rod 24 are also mounted on the sliding seat 2, with the power component 23 and the linkage guide rod 24 being connected in a transmission manner. Preferably, the power component 23 is also a servo motor. A linkage rod 26 is mounted on the movable end of the power component 23, and the linkage rod 26 is threadedly connected to the linkage guide rod 24. The linkage guide rod 24 is slidably engaged with the sliding seat 2. When the power component 23 drives the linkage rod 26 to rotate, the linkage guide rod 24 causes the mounting base 51 to slide along the sliding seat 2.

[0045] Reference Figure 3 In at least one embodiment, a tapered head 25 is mounted on the end of the linkage guide rod 24 facing the gripper 52, and the tapered head 25 is positioned between the two grippers 52. When the power member 23 drives the linkage guide rod 24 to slide towards the gripper 52, the tapered head 25 pushes the two grippers 52 to open to both sides. Conversely, when the linkage guide rod 24 drives the tapered head 25 to slide in the opposite direction, the two grippers 52 retract inward under the action of the spring 53, thereby achieving the gripping action.

The apparatus embodiments described above are merely illustrative. For example, the division of units is only a logical functional division, and in actual implementation, there may be other division methods. Furthermore, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Based on the above-described ideal embodiments of this utility model, and through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification; its technical scope must be determined according to the scope of the claims.
