[0002] Semiconductor chips are semiconductor devices that can achieve certain functions by etching and wiring on semiconductor sheets. They are widely used in electronic devices such as mobile phones, computers, televisions and automobiles.

[0003] In the manufacturing process of semiconductor chips, the resin material needs to be transported one by one from the vibration plate track to the feeding track, which requires a mechanism to guide and turn the conveying track.

[0004] Conventional mechanisms that use rotary cylinders cannot rotate continuously in the same direction, resulting in low efficiency. Mechanisms that use motors to directly drive the turntable also have problems such as complex positioning and difficult debugging. Summary of the invention

[0005] The present invention provides a rotary feeding mechanism which has the advantages of high efficiency, precise positioning and simple structure, so as to solve the problems raised in the background technology.

[0006] In order to solve the defects of low efficiency, complex positioning and difficult debugging of the existing rotary feeding mechanism, the present invention provides the following technical solutions: a rotary feeding mechanism, comprising a loading plate and a lower base plate, four supporting columns are fixedly connected between the loading plate and the lower base plate, a driving shaft is installed between the loading plate and the lower base plate, a driven shaft is installed between the loading plate and the lower base plate, the driving shaft sleeve is provided with a driving disk, the driving disk is fixedly connected to the driving shaft, two guide wheels are fixedly installed on the bottom surface of the driving disk, a rotating disk is fixedly installed on the top end of the driven shaft, the driven shaft sleeve is provided with a guide disk, and the guide disk is fixedly connected to the driven shaft.

[0007] As a preferred technical solution of the present invention, a motor is fixedly mounted on the bottom bolt of the lower base plate, and the bottom of the driving shaft is drivingly connected to the motor.

[0008] As a preferred technical solution of the present invention, the outer wall of the guide plate is provided with four guide grooves, and the guide grooves match the guide wheels.

[0009] As a preferred technical solution of the present invention, a pair of arc-shaped bosses are fixedly connected to the bottom end of the active disk, and the arc-shaped bosses can be fitted on the arc-shaped outer wall of the guide disk.

[0010] As a preferred technical solution of the present invention, four groups of tracks are provided on the top surface of the rotating disk, the four groups of tracks are distributed in a circle, and each group of tracks is fixedly connected to the rotating disk by bolts.

[0011] As a preferred technical solution of the present invention, the guide plate drives the driven shaft to rotate, and the rotating plate rotates following the driven shaft to complete a precise rotation of 45° each time.

[0012] As a preferred technical solution of the present invention, a plurality of first mounting holes are formed on the top surface of the lower base plate, and a plurality of second mounting holes are formed on the top surface of the loading plate.

[0013] Compared with the prior art, the present invention provides a rotary feeding mechanism with the following beneficial effects: an active disk is driven to rotate by a motor, two guide wheels are arranged on the active disk, and together with the guide disk with guide grooves, the rotary disk can rotate 45° each time; since the arc-shaped boss fits on the guide disk, the guide disk can be limited, so that after the rotary disk rotates 45°, it will not shake within a short period of time, so that the rotary disk can rotate 45° in one direction at set intervals, which can be used for horizontal feeding and steering of resin materials with accurate directional accuracy and high working efficiency. The motor in the mechanism can rotate continuously in one direction without frequent opening and closing, the motor is not prone to failure, and has high working stability. At the same time, there will be no complex positioning and difficult debugging, and the structure is also very simple and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 4 The present invention discloses a rotary feeding mechanism, including a loading plate 10 and a lower base plate 20, four supporting columns 30 are fixedly connected between the loading plate 10 and the lower base plate 20, a driving shaft 40 is installed between the loading plate 10 and the lower base plate 20, a driven shaft 50 is installed between the loading plate 10 and the lower base plate 20, the driving shaft 40 is sleeved with a driving disk 60, the driving disk 60 is fixedly connected to the driving shaft 40, two guide wheels 70 are fixedly installed on the bottom surface of the driving disk 60, a rotating disk 80 is fixedly installed on the top of the driven shaft 50, the driven shaft 50 is sleeved with a guide disk 90, and the guide disk 90 is fixedly connected to the driven shaft 50.

[0022] Specifically, the motor 100 is fixedly mounted on the bottom of the lower base plate 20 by bolts, and the bottom of the driving shaft 40 is drivingly connected to the motor 100 .

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

[0024] Specifically, the outer wall of the guide plate 90 is provided with four guide grooves 200 , which match the guide wheel 70 . The bottom end of the active plate 60 is fixedly connected with a pair of arc-shaped bosses 300 , which can be fitted on the arc-shaped outer wall of the guide plate 90 .

[0025] In this embodiment, the guide groove 200 can be used in conjunction with the guide wheel 70 to drive the guide plate 90 to rotate, and the arc-shaped boss 300, when fitted to the arc-shaped outer wall of the customized-shaped guide plate 90, can achieve a limited locking of the guide plate 90, that is, the active plate 60 rotates, while the guide plate 90 does not rotate.

[0026] Specifically, four groups of tracks 400 are provided on the top surface of the rotating disk 80 . The four groups of tracks 400 are distributed in a circle, and each group of tracks 400 is fixedly connected to the rotating disk 80 by bolts.

[0027] In this embodiment, the track 400 can be used in conjunction with a conveying device to convey the resin material on the conveying device to the track 400 on the rotating disk 80 .

[0028] Specifically, the guide plate 90 drives the driven shaft 50 to rotate, and the rotating plate 80 rotates following the driven shaft 50 to complete a movement of accurately rotating by 45° each time.

[0029] In this embodiment, the connection relationship between the guide plate 90 and the rotating plate 80 is introduced. Since the guide plate 90 rotates at intervals of 45° each time, the rotating plate 80 also rotates at intervals of 45° each time.

[0030] Specifically, a plurality of first mounting holes 500 are formed on the top surface of the lower base plate 20 , and a plurality of second mounting holes 600 are formed on the top surface of the loading plate 10 .

[0032] The working principle and use process of the present invention are as follows: when the equipment is running, the resin material enters the track 400 on the rotating disk 80 from the conveying device on one side of the rotating disk 80, and the motor 100 drives the driving shaft 40 to rotate, and the driving disk 60 rotates accordingly. During rotation, the guide wheel 70 enters one of the guide grooves 200 on the guide disk 90, and at this time, the guide disk 90 can be driven to rotate. After rotating to 45°, the guide wheel 70 disengages from the guide groove 200, and the arc-shaped boss 300 on the driving disk 60 just fits with the arc-shaped outer wall of the guide disk 90. ​​At this time, the driving disk 60 rotates while the guide disk 90 no longer rotates, so that the rotating disk 80 can be intermittently stopped and accurately rotated 45° each time.
