Description

Technical Field

[0001] This utility model relates to the field of semiconductor chip manufacturing technology, specifically a rotary feeding mechanism. Background Technology

[0002] Semiconductor chips are semiconductor devices that perform a certain function by etching and wiring on semiconductor wafers. They are widely used in electronic devices such as mobile phones, computers, televisions, and automobiles.

[0003] In the semiconductor chip manufacturing process, the resin material needs to be transported one by one from the vibratory feeder track to the feeding track, which requires a mechanism for guiding and turning the conveyor track.

[0004] Mechanisms that conventionally use rotary cylinders cannot rotate continuously in the same direction, resulting in low efficiency; while mechanisms that directly drive the turntable to rotate with a motor also have issues such as complex positioning and difficult debugging. Utility Model Content

[0005] This invention provides a rotary feeding mechanism that has the advantages of high efficiency, accurate positioning, and simple structure, thereby solving the problems mentioned in the background art.

[0006] To address the shortcomings of existing rotary feeding mechanisms, such as low efficiency, complex positioning, and difficult debugging, this utility model provides the following technical solution: A rotary feeding mechanism includes an upper plate and a lower base plate. Four support columns are fixedly connected between the upper plate and the lower base plate. A drive shaft is installed between the upper plate and the lower base plate, and a driven shaft is installed between the upper plate and the lower base plate. A drive disc is sleeved on the drive shaft, and the drive disc is fixedly connected to the drive shaft. Two guide wheels are fixedly installed on the bottom surface of the drive disc. A rotating disk is fixedly installed on the top of the driven shaft, and a guide disc is sleeved on the driven shaft. The guide disc is fixedly connected to the driven shaft.

[0007] As a preferred embodiment of this utility model, a motor is fixedly installed on the bottom of the lower base plate by bolts, and the bottom of the drive shaft is connected to the motor for transmission.

[0008] As a preferred embodiment of this utility model, the outer wall of the guide disc is provided with four guide grooves, which are matched with the guide wheel.

[0009] As a preferred embodiment of this utility model, a pair of arc-shaped protrusions are fixedly connected to the bottom end of the active disk, and the arc-shaped protrusions can fit against the outer arc surface of the guide disk.

[0010] As a preferred embodiment of this utility model, the top surface of the rotating disk is provided with four sets of tracks, which are distributed in a circular pattern, and each set of tracks is bolted to the rotating disk.

[0011] As a preferred embodiment of this utility model, the guide disk drives the driven shaft to rotate, and the rotating disk follows the driven shaft to rotate, completing a precise 45° rotation each time.

[0012] As a preferred embodiment of this utility model, the top surface of the lower base plate is provided with a plurality of first mounting holes, and the top surface of the upper plate is provided with a plurality of second mounting holes.

[0013] Compared with the prior art, this utility model provides a rotary feeding mechanism with the following advantages: the active disk is driven to rotate by a motor, and two guide wheels are set on the active disk. In conjunction with the guide disk with guide grooves, the rotary disk can rotate 45° each time. Since the arc-shaped boss is attached to the guide disk, the guide disk can be limited, so that the rotary disk will not wobble for a short time after rotating 45°. Thus, the rotary disk can rotate 45° in one direction at set intervals. It can be used for horizontal feeding and turning of resin material with accurate directional accuracy and high working efficiency. The motor in this mechanism can rotate continuously in one direction without frequent starting and stopping. The motor is not prone to failure and has high working stability. At the same time, there is no complicated positioning or difficult debugging. The structure is also very simple and reliable. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model discloses a rotary feeding mechanism, including an upper plate 10 and a lower base plate 20. Four support columns 30 are fixedly connected between the upper plate 10 and the lower base plate 20. An active shaft 40 is installed between the upper plate 10 and the lower base plate 20. A driven shaft 50 is installed between the upper plate 10 and the lower base plate 20. An active disc 60 is sleeved on the active shaft 40 and is fixedly connected to the active shaft 40. Two guide wheels 70 are fixedly installed on the bottom surface of the active disc 60. A rotating disc 80 is fixedly installed on the top of the driven shaft 50. A guide disc 90 is sleeved on the driven shaft 50 and is fixedly connected to the driven shaft 50.

[0022] Specifically, the bottom of the lower base plate 20 is bolted to the bottom of the motor 100, and the bottom of the drive shaft 40 is connected to the motor 100 for transmission.

[0023] In this embodiment, the drive shaft 40 can be driven to rotate, and the motor 100 can rotate continuously in one direction without frequent starting and stopping.

[0024] Specifically, the outer wall of the guide disk 90 is provided with four guide grooves 200, which are matched with the guide wheel 70. The bottom end of the drive disk 60 is fixedly connected with a pair of arc-shaped bosses 300, which can fit against the arc-shaped outer wall of the guide disk 90.

[0025] In this embodiment, the guide groove 200 can be used in conjunction with the guide wheel 70 to drive the guide disk 90 to rotate. When the arc-shaped boss 300 is attached to the arc-shaped outer wall of the customized guide disk 90, it can limit and lock the guide disk 90, that is, the active disk 60 rotates while the guide disk 90 does not rotate.

[0026] Specifically, the top surface of the rotating disk 80 is provided with four sets of tracks 400, which are distributed in a circle, and each set of tracks 400 is bolted to the rotating disk 80.

[0027] In this embodiment, the track 400 can be used in conjunction with a conveying device to transport resin material from the conveying device to the track 400 on the rotary table 80.

[0028] Specifically, the guide disk 90 drives the driven shaft 50 to rotate, and the rotating disk 80 follows the driven shaft 50 to rotate, completing a precise 45° rotation each time.

[0029] In this embodiment, the connection between the guide disk 90 and the rotating disk 80 is described. Since the guide disk 90 rotates 45° at each interval, the rotating disk 80 also rotates 45° at each interval.

[0030] Specifically, the top surface of the bottom plate 20 is provided with multiple first mounting holes 500, and the top surface of the top plate 10 is provided with multiple second mounting holes 600.

[0031] In this embodiment, the first mounting hole 500 can fix the lower base plate 20 on the equipment (semiconductor chip manufacturing apparatus), while the second mounting hole 600 facilitates the installation of related components of the equipment.

[0032] The working principle and usage process of this utility model are as follows: When the equipment is running, the resin material enters the track 400 on the rotating disk 80 from one side of the conveying device. The motor 100 drives the drive shaft 40 to rotate, and the drive disk 60 rotates accordingly. When rotating, the guide wheel 70 enters one of the guide grooves 200 on the guide disk 90, which drives the guide disk 90 to rotate. After rotating to 45°, the guide wheel 70 disengages from the guide groove 200, and the arc-shaped protrusion 300 on the drive disk 60 just fits against the outer wall of the arc surface of the guide disk 90. ​​At this time, the drive disk 60 rotates while the guide disk 90 stops rotating, which can realize the action of the rotating disk 80 to rotate intermittently and stop precisely at 45° each time.
