[0032] Embodiment 1:

[0033] As Figures 1 to 9 shown, the material receiving mechanism of the present invention includes: a fixed plate 1 and a turntable 2. The fixed plate 1 and the turntable 2 are connected by a middle shaft 3 in the axial direction. The middle shaft 3 and the turntable 2 are configured to rotate synchronously relative to the fixed plate 1; a material receiving structure 4 and a synchronous transmission structure 5. At least one set of the material receiving structure 4 is rotationally arranged on the surface of the turntable 2 on the side away from the fixed plate 1. The synchronous transmission structure 5 is arranged on the fixed plate 1 and the turntable 2 to control the material receiving structure 4 to rotate circumferentially while maintaining a predetermined angle unchanged when the material receiving structure 4 rotates synchronously with the turntable 2.

[0034] See Figure 3 As shown in the figure, the fixed plate 1 is parallel to the turntable 2. The turntable 2 is rotatably mounted on the fixed plate 1 through the central shaft 3. At least one set of material receiving structures 4 arranged on the surface of the turntable 2 away from the fixed plate 1 can rotate relative to the turntable 2. The synchronous transmission structure 5 is arranged on the fixed plate 1 and the turntable 2. When the turntable 2 rotates, the synchronous transmission structure 5 can restrict the rotation of the material receiving structure 4, ensuring that when the turntable 2 rotates, the material receiving structure 4 rotates synchronously, so that the material receiving structure 4 can always hold the material upward.

[0035] See Figures 1 to 7 As shown in the figure, when conveying plate-shaped or sheet-shaped materials (silicon wafers), the silicon wafers are fed onto the material receiving structure 4. The central shaft 3 is controlled to drive the turntable 2 to rotate clockwise, so that the turntable 2 and the central shaft 3 rotate relative to the fixed plate 1. Under the action of the synchronous transmission structure 5, the material receiving structure 4 can always support the material upward and rotate circumferentially to change its position. It should be noted that the left side of the turntable 2 can be regarded as the loading position, and the right side of the turntable 2 can be regarded as the unloading position. When the material receiving structure 4 at the loading position receives the material, after the above operation, the material receiving structure 4 rotates clockwise to the unloading position, and then the material can be taken off by the staff or the manipulator. The material receiving mechanism of the present application can be used as a transfer device between the silicon wafer production line and the storage device to realize rapid loading and unloading operations, improve the loading and unloading efficiency of materials, and has practicability.

[0036] In other possible embodiments, the material receiving structure 4 can be configured with two groups, three groups, four groups, etc., without specific limitation; correspondingly, the number of the synchronous transmission structures 5 arranged between the fixed plate 1 and the turntable 2 corresponds to the material receiving structure 4 one by one.

[0037] In one or more embodiments, the synchronous transmission structure 5 at least includes a first driving gear 51 and a second driving gear 52 that are sequentially and rotatably arranged on the turntable 2 along the radial direction of the turntable 2, and a fixed gear 53 arranged on the fixed plate 1; wherein, the first driving gear 51 meshes with the second driving gear 52, the first driving gear 51 meshes with the fixed gear 53, the fixed gear 53 is coaxial with the turntable 2 and does not rotate, and the second driving gear 52 is connected to the material receiving structure 4 to rotate synchronously.

[0038] See Figures 1 to 7 As shown in the figure, the first driving gear 51 and the second driving gear 52 are sequentially arranged on the surface of the turntable 2 facing the fixed plate 1 along the radial direction of the turntable 2. The first driving gear 51 meshes with the second driving gear 52, the second driving gear 52 is connected to the material receiving structure 4 and rotates synchronously. The fixed plate 1 is fixedly installed with a fixed gear 53 on the surface facing the turntable 2. The fixed gear 53 meshes with the first driving gear 51. The fixed gear 53 is coaxial with the turntable 2 and the central shaft 3, and the central shaft 3 is located inside the fixed gear 53.

[0039] See Figure 3 When the material receiving structure 4 is rotated clockwise from the feeding position to the discharging position for conveying, first, the central shaft 3 is controlled to rotate clockwise so that the turntable 2 drives the material receiving structure 4 to rotate clockwise. When the material receiving structure 4 passes through the feeding position, it can receive and hold the material. As the turntable 2 rotates clockwise, the first driving gear 51 rotates clockwise relative to the fixed gear 53, and the second driving gear 52 rotates counterclockwise relative to the fixed gear 53, so that the material receiving structure 4 can rotate in the opposite direction to the turntable 2 while rotating and rising clockwise, thereby ensuring the stability of the material receiving structure 4 for rotating and conveying the material. At the same time, by increasing the number of the material receiving structures 4, the feeding and material receiving rates of the present application can be further improved.

[0040] See Figures 2 to 7 When the material receiving structure 4 is rotated clockwise from the discharging position to the feeding position for conveying, the central shaft 3 is also controlled to drive the turntable 2 to rotate clockwise. The first driving gear 51 rotates clockwise relative to the fixed gear 53, and the second driving gear 52 rotates counterclockwise relative to the fixed gear 53, so that while the turntable 2 rotates clockwise, the material receiving structure 4 rotates counterclockwise on the turntable 2, ensuring that the side of the material receiving structure 4 for holding the material is always upward, so as to facilitate receiving the material at the feeding position and discharging the material at the discharging position, which has practicability.

[0041] It should be noted that the central shaft 3 can also be controlled to drive the turntable 2 to rotate counterclockwise. At this time, the first driving gear 51 rotates counterclockwise and the second driving gear 52 rotates clockwise, so that the material receiving structure 4 that rotates synchronously with the second driving gear 52 rotates clockwise relative to the turntable 2; by reversing the operation of the turntable 2, the feeding and discharging of the material can also be realized.

[0042] In one or more embodiments, a bearing 6 is embedded in the turntable 2. A connecting shaft 7 with opposite first end 71 and second end 72 is arranged on the inner ring of the bearing 6. The first end 71 and the second end 72 respectively extend out of both sides of the turntable 2. The first end 71 is used to connect the material receiving structure 4, and the second end 72 is used to connect the synchronous transmission structure 5; the material receiving structure 4 is a receiving frame rotatably installed on the turntable 2.

[0043] See Figures 6 to 8 As shown in, the outer peripheral circle of the bearing 6 is embedded in the turntable 2, the connecting shaft 7 is fixedly connected to the inner side of the bearing 6, the connecting shaft 7 has opposite first end 71 and second end 72, the first end 71 is used to connect the receiving frame, and the second end 72 is used to connect the second driving gear 52. Through this setting, the synchronous rotation of the second driving gear 52 and the receiving frame can be realized. At the same time, the second driving gear 52 and the receiving frame are connected to the turntable 2 through the bearing 6, which can improve the stability and smoothness of the receiving frame during rotation and improve the use effect of the present application.

[0044] In one or more embodiments, the inclination angle of the material receiving structure 4 relative to the connecting shaft 7 is adjustable.

[0045] See Figure 2 、 Figure 9 , an arc-shaped waist-shaped hole 41 is formed on the material receiving frame, and a threaded hole corresponding to the arc-shaped waist-shaped hole 41 is arranged at the first end 71 of the connecting shaft 7. The material receiving frame is connected to the threaded hole by passing a bolt through the arc-shaped waist-shaped hole 41, so as to realize the angle adjustment of the material receiving frame. By inclining the material receiving frame, it is convenient for the material to be placed more stably, and the stability of the material conveying in this application is improved.

[0046] In one or more embodiments, the central shaft 3 is driven by a driving device 8 to rotate; an outer housing 9 is arranged outside the fixed plate 1 and the turntable 2, and the driving device 8 is covered by the outer housing 9.

[0047] See Figure 1 、 Figure 2 、 Figure 3 , the driving device 8 can be a servo motor; by covering the fixed plate 1, the turntable 2, the driving device 8 and the synchronous transmission structure 5 with the outer housing 9, the protection of the components can be formed, and at the same time, the aesthetic degree of the material receiving mechanism can be improved.

[0048] In one or more embodiments, a baffle 10 for covering the turntable 2 is arranged on the outer peripheral side of the turntable 2, and the baffle 10 rotates synchronously with the turntable 2. By this setting, the covering of the turntable 2 can be further formed, and the aesthetic degree of the overall appearance of the material receiving mechanism is improved.

[0049] In one or more embodiments, the turntable 2 is detachably mounted on the central shaft 3. See Figure 2 、 Figure 7 , the turntable 2 is detachably mounted on the central shaft 3 by bolts. By this setting, the assembly of the turntable 2 and the synchronous transmission structure 5 can be facilitated, and the replacement of components can be facilitated.

[0050] Embodiment 2:

[0051] As the second embodiment of the present utility model, the components that are the same or corresponding to those in the first embodiment adopt the corresponding reference numerals in the first embodiment, and only the differences between the second embodiment and the first embodiment will be described below.

[0052] The difference between the second embodiment and the first embodiment lies in the synchronous transmission structure 5. In the second embodiment, the synchronous transmission structure 5 is a first belt pulley rotatably mounted on the turntable 2, a second belt pulley arranged on the fixed plate 1, and a transmission belt for connecting the first belt pulley and the second belt pulley; wherein, the first belt pulley is connected to the material receiving structure 4 to rotate synchronously, and the second belt pulley is coaxial with the turntable 2.

[0053] It should be noted that the second pulley does not rotate, the first pulley can rotate relative to the turntable 2, and the first pulley rotates synchronously with the material receiving structure 4. When the turntable 2 rotates clockwise, under the action of the transmission belt, the first pulley can rotate counterclockwise relative to the turntable 2, that is, the first pulley and the material receiving structure 4 reverse relative to the turntable 2 to keep the material receiving structure 4 always receiving the material.
