[0059] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0060] During the processing of wafers (such as silicon wafers and battery wafers), in order to realize the flow of wafers in different processes, the wafers need to be transported, and in some processes, the wafers need to be rotated and transported.

[0061] Currently, to achieve rotary conveying of sheets, a suction rotation mechanism is typically installed above the conveyor line. This existing suction rotation mechanism consists of a rotary drive member and a suction mechanism. The driving end of the rotary drive member is connected to the suction mechanism, which sucks the sheet from the suction conveyor line. After the rotary drive member rotates the suction mechanism and the sheet through a preset angle, the suction mechanism releases the sheet back onto the suction conveyor line. During rotation, the driving end of the rotary drive member must drive the entire suction mechanism, resulting in a heavy rotational load on the driving end of the rotary drive member, which reduces the efficiency of sheet rotation.

[0062] Therefore, this application proposes a sheet rotating mechanism 10, see Figure 1 and Figure 2 As shown, a sheet rotation mechanism 10 proposed in an embodiment of the present application includes a first driving member 11, an adsorption member 12 and a rotating member 13. The receiving surface of the rotating member 13 is protruding from the adsorption surface of the adsorption member 12. The adsorption member 12 is configured to adsorb the sheet 20 in a non-contact manner to attach the sheet 20 to the receiving surface of the rotating member 13. The adsorption member 12 is also configured to release the sheet 20 adsorbed and fixed on the receiving surface of the rotating member 13; the driving end of the first driving member 11 is connected to the first end of the rotating member 13, and the first driving member 11 is configured to drive the rotating member 13 to rotate a preset angle to drive the sheet 20 on the rotating member 13 to rotate a preset angle.

[0063] Specifically, the first driving member 11 is a servo motor or a stepping motor.

[0064] The sheet rotation mechanism 10 proposed in the present application uses the adsorption part 12 to non-contactly adsorb the sheet 20, so that the sheet 20 is attached to the receiving surface of the rotating part 13, and the first driving part 11 drives the rotating part 13 to rotate to drive the sheet 20 to rotate; compared with the overall rotation of the existing adsorption mechanism, when the sheet rotation mechanism 10 proposed in the present application rotates the sheet 20, the adsorption part 12 does not move, and the first driving part 11 only drives the rotating part 13 to drive the sheet 20 to rotate, which greatly reduces the rotation load of the first driving part 11 and improves work efficiency.

[0065] See also Figure 1 、 Figure 2 and Figure 4 As shown, as an embodiment, the rotating member 13 includes a connecting shaft 130 and a receiving plate 131. The first end of the connecting shaft 130 is connected to the driving end of the first driving member 11. The receiving plate 131 is arranged at the second end of the connecting shaft 130. The receiving surface of the receiving plate 131 protrudes from the adsorption surface of the adsorption member 12, and the sheet 20 is adsorbed and fixed on the receiving surface of the receiving plate 131.

[0066] Specifically, a connecting hole 1300 is formed on the end surface of the first end of the connecting shaft 130. The rotating shaft of the first driving member 11 is inserted into the connecting hole 1300 and is anti-rotationally connected by a keyway. A first fixing hole 1301 is formed on the side surface of the first end of the connecting shaft 130, which is connected to the connecting hole 1300. The first fixing hole 1301 is a threaded hole. A fixing screw is installed in the first fixing hole 1301 and laterally locks and fixes the connecting shaft 130 in the connecting hole 1300, thereby fixedly connecting the rotating shaft of the first driving member 11 to the first end of the connecting shaft 130. In order to ensure that the rotating shaft of the first driving member 11 and the connecting shaft 130 are tightly connected, the connecting shaft 130 and the rotating shaft of the first driving member 11 can also be locked at other positions of the connecting shaft 130 by screws or the like to prevent the connecting shaft 130 from separating from the rotating shaft of the first driving member 11 during rotation.

[0067] By setting the connecting shaft 130, the connection between the rotating member 13 and the driving end of the first driving member 11 is achieved. By setting the receiving plate 131, the sheet body 20 is stably and reliably received, providing a rotating member 13 with a simple structure and stably and reliably receiving the sheet body 20.

[0068] As an embodiment, the adsorption member 12 is a Bernoulli suction cup.

[0069] By configuring the adsorption member 12 as a Bernoulli suction cup, a fast, efficient, and reliable non-contact adsorption member 12 is provided.

[0070] See also Figure 2 、 Figure 4 and Figure 5As shown, as an embodiment, the Bernoulli suction cup includes a base 120 and a suction cup body 121. The suction cup body 121 is detachably and sealedly mounted on the base 120. An air cavity is formed between the suction cup body 121 and the base 120. The base 120 is provided with at least one air inlet hole connected to the air cavity. The suction cup body 121 is provided with a plurality of exhaust holes 122 located on the periphery of the receiving tray 131. The plurality of exhaust holes 122 are connected to the air cavity. Compressed air enters the air cavity through the air inlet hole and is discharged from the plurality of exhaust holes 122 to form an adsorption area based on the Bernoulli effect on the periphery of the receiving tray 131.

[0071] Specifically, the suction cup body 121 is provided with a plurality of second fixing holes 123 on the periphery of the air cavity. The second fixing holes 123 are threaded holes, and fixing bolts are passed through the second fixing holes 123 to securely connect the base 120 to the suction cup body 121 .

[0072] Specifically, an air pipe connector 124 is installed on each air inlet, and the air pipe connector 124 is connected to the air source through an air pipe.

[0073] Through the cooperation between the base 120 and the suction cup body 121, an adsorption area based on the Bernoulli effect is formed on the periphery of the receiving plate 131, providing a Bernoulli suction cup with a simple structure, low cost and easy processing.

[0074] As an embodiment, a first center hole 125 is opened on the base 120, and a second center hole 126 is opened on the suction cup body 121. The first center hole 125 and the second center hole 126 are connected and form an accommodating cavity. The connecting shaft 130 is rotatably arranged in the accommodating cavity.

[0075] By providing center holes on both the base 120 and the suction cup body 121 and rotatably passing the connecting shaft 130 through the accommodating cavity formed by the two center holes, an assembly method for the rotating part 13 with a compact structure, small space occupation and reasonable layout is provided.

[0076] See also Figure 2 、 Figure 3 and Figure 5 As shown, as an embodiment, a circle of annular air guide grooves 127 located outside the second center hole 126 is provided on the first side surface of the suction cup body 121, and a circle of annular adsorption grooves 128 located outside the second center hole 126 is provided on the second side surface of the suction cup body 121. The base 120 is covered on the suction cup body 121 and seals the annular air guide grooves 127 to form an air cavity. The first ends of several exhaust holes 122 extend into the annular air guide grooves 127, and the second ends of several exhaust holes 122 extend into the annular adsorption grooves 128.

[0077] By disposing the suction cup body 121 , a continuous annular adsorption area is formed on the periphery of the receiving disk 131 , thereby improving the adsorption stability and reliability of the Bernoulli suction cup.

[0078] It should be noted that the Bernoulli suction cup in the present application is not limited to the above-mentioned structure. Any structure that can generate adsorption so that the sheet 20 is attached to the receiving surface of the rotating part 13 is within the protection scope of the present application.

[0079] See also Figure 1 、 Figure 2 and Figure 4 As shown, as an embodiment, a gasket 132 for increasing the friction force of the receiving surface of the receiving tray 131 is laid on the receiving surface of the receiving tray 131 .

[0080] By laying the gasket 132 on the receiving surface of the receiving disc 131, the friction between the receiving surface of the receiving disc 131 and the sheet 20 is increased, thereby preventing the sheet 20 from moving relative to the receiving surface of the receiving disc 131 during the rotation of the sheet 20.

[0081] As an embodiment, the gasket 132 is laid along the outer peripheral edge of the receiving surface of the receiving plate 131, and at least one vent hole 133 is provided on the receiving surface of the receiving plate 131 located inside the gasket 132. At least one vent hole 133 is connected to the accommodating cavity. The fixed end of the first driving member 11 is installed on the base 120, and the base 120 is provided with a notch 129 connected to the accommodating cavity.

[0082] By providing at least one vent hole 133 connected to the accommodating chamber on the receiving surface of the receiving tray 131, a weight-reducing effect is achieved, and a notch 129 connected to the accommodating chamber is opened on the base 120, so that the receiving tray 131 is connected to the atmosphere, thereby avoiding the sheet body 20 from being released due to the negative pressure formed between the receiving tray 131 and the sheet body 20 when the sheet body is released; at the same time, the notch 129 can also be used to observe whether the connecting shaft 130 inside the accommodating chamber and the driving end of the first driving member 11 are installed in place.

[0083] As an embodiment, the gasket 132 includes a plurality of anti-slip pads 1320 arranged on the receiving surface of the receiving plate 131 at intervals along the circumferential direction, and an air outlet gap 134 is defined between two adjacent anti-slip pads 1320 .

[0084] By configuring the gasket 132 to include several anti-slip pads 1320 , with an air vent 134 between two adjacent anti-slip pads 1320 , the friction between the receiving surface of the receiving tray 131 and the sheet body 20 is increased while achieving communication between the receiving tray 131 and the atmosphere, which is beneficial to the smooth release of the sheet body 20 .

[0085] Please refer to Figure 1 and Figure 2 As shown, as an embodiment, a first sensing member 30 and a second sensing member 31 are installed on the base 120, wherein: the first sensing member 30 is configured to detect whether the sheet 20 is close to the rotating member 13 to control the operation of the first driving member 11 and the adsorption member 12; the second sensing member 31 is configured to detect whether the sheet 20 on the rotating member 13 is released.

[0086] Specifically, the first sensing member 30 is a capacitive sensor. When the first sensing member 30 detects that the sheet 20 is directly below the rotating member 13, the adsorption member 12 is controlled to generate an adsorption force so that the sheet 20 is attached to the supporting surface of the rotating member 13. After the first driving member 11 drives the rotating member 13 to rotate a preset angle, the adsorption member 12 stops working and releases the sheet 20 on the supporting surface of the rotating member 13.

[0087] Specifically, the second sensing member 31 is a capacitive sensor. When the second sensing member 31 detects that the sheet 20 on the receiving surface of the rotating member 13 has not been released, an alarm is issued. To ensure that both sides of the sheet 20 are fully released, the second sensing member 31 includes two capacitive sensors spaced apart and mounted on the base 120. The two capacitive sensors are respectively arranged above the sheet 20 on either side of the receiving surface. Each capacitive sensor is used to detect whether the corresponding side of the sheet 20 on the receiving surface of the rotating member 13 is released.

[0088] By providing the first sensing element 30 , automatic control of adsorption, rotation and release of the sheet 20 is achieved; by providing the second sensing element 31 , automatic detection of whether the sheet 20 on the rotating element 13 is released is achieved.

[0089] As an embodiment, the height difference between the receiving surface of the rotating member 13 and the adsorption surface of the adsorption member 12 ranges from 0.2 mm to 1.5 mm.

[0090] Specifically, the height difference between the supporting surface of the rotating part 13 and the adsorption surface of the adsorption part 12 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm.

[0091] By setting the height difference between the receiving surface of the rotating member 13 and the adsorption surface of the adsorption member 12 , the friction between the receiving surface of the rotating member 13 and the sheet body is ensured, ensuring that the rotating member 13 can drive the sheet body 20 to rotate.

[0092] The sheet rotation mechanism proposed in this embodiment has the following advantages compared with the prior art:

[0093] 1) A driving mode is adopted in which the adsorption member remains stationary and the first driving member only drives the rotating member to drive the sheet body to rotate, which greatly reduces the rotation load of the first driving member and improves work efficiency.

[0094] 2) The Bernoulli suction cup is used to adsorb the sheet, which has a better adsorption effect.

[0095] This application also proposes a sheet rotating conveying device, see Figure 1 and Figure 6 As shown, the sheet rotation conveying device proposed in the embodiment of the present application includes a first conveying mechanism 40, a second conveying mechanism 50 and a sheet rotation mechanism 10. At least one adsorption position is provided on the conveying path of the first conveying mechanism 40, and a sheet rotation mechanism 10 is provided above each adsorption position. The first conveying mechanism 40 is configured to convey the sheet 20 to the adsorption position; the sheet rotation mechanism 10 is configured to adsorb the sheet 20 on the adsorption position and rotate the adsorbed sheet 20 by a preset angle and then release it to the second conveying mechanism 50; the second conveying mechanism 50 is configured to receive the sheet 20 released by the sheet rotation mechanism 10 and convey the received sheet 20 to the next process.

[0096] Through the cooperation of the first conveying mechanism 40 , the second conveying mechanism 50 and the sheet rotating mechanism 10 , the sheet is rotated by a preset angle and then conveyed to the next process.

[0097] As an embodiment, the first conveying mechanism 40 is configured to convey Figure 6 The sheet 20 is conveyed to the adsorption position in the X direction in the first direction. The second conveying mechanism 50 is configured to convey the received sheet 20 to the next process along the first direction.
