[0062] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0063] like Figures 1 to 6 As shown, the adsorption unit 10 in the embodiment of the present application includes an adsorption block 1 and an air guide 2, wherein:

[0064] A first air cavity connected to a compressed air source is provided in the adsorption block 1. A first blowing slit 15 extending along a first direction and connected to the first air cavity is provided on the adsorption surface of the adsorption block 1. After the compressed air enters the first air cavity, it is blown out from the first blowing slit 15 to generate an adsorption area on the adsorption surface of the adsorption block 1.

[0065] The air guide member 2 is located at the side of the adsorption block 1, and at least one (for example, two in the figure) air guide surface of the air guide member 2 is provided along the first direction (for example, Figure 1 and Figure 2 The air duct 21 extends in the X-axis direction (in the X-axis direction), and part of the compressed air blown out from the first blowing slit 15 enters the air duct 21 along the adsorption surface of the adsorption block. The compressed air flows in the air duct 21 along the direction away from the plane where the adsorption surface of the adsorption block 1 is located and is blown out from the air outlet end of the air duct 21.

[0066] The adsorption unit 10 of the embodiment of the present application is provided with an air guide member 2 on the side of the adsorption block 1. Part of the compressed air blown out by the adsorption block 1 enters into the air guide 21 of the air guide member 2 along the adsorption surface of the adsorption block 1, and is blown out from the air outlet end of the air guide 21 under the guidance of the air guide 21. The air outlet end of the air guide 21 is far away from the adsorption surface of the adsorption block 1, thereby avoiding interference with the sheet outside the adsorption area.

[0067] The adsorption unit 10 in the embodiment of the present application is suitable for adsorbing a wafer (such as a silicon wafer or a battery wafer, etc.) located on a wafer conveying line, or placing the wafer on the wafer conveying line.

[0068] Optional, such as Figures 3 to 6As shown, the air duct 21 is an inclined channel, and the angle between the air duct 21 and the adsorption surface of the adsorption block 1 is an obtuse angle. In this way, the air inlet end of the air duct 21 is inclined toward the first air blowing slit 15, ensuring that part of the compressed air blown out of the first air blowing slit 15 enters the air duct 21 along the adsorption surface of the adsorption block 1, and ensuring that the gas at the air outlet end of the air duct 21 is blown out in a direction away from the plane where the adsorption surface of the adsorption block 1 is located.

[0069] Optionally, the air guide member 2 is provided with at least two air guide channels 21, for example Figures 1 to 6 Two of the examples. Figure 6 As shown, the air inlet ends of the two air guide passages 21 are arranged at intervals along the direction in which the compressed gas flows on the adsorption surface of the adsorption block 1 .

[0070] By providing more than two air guide channels 21 , as much compressed air blown out from the first air blowing slot 15 as possible enters the air guide channel 21 , further reducing the possibility of the airflow interfering with the sheet outside the adsorption area.

[0071] In order to facilitate the processing and forming of the air guide member 2, and to make the structure of the adsorption unit in the embodiment of the present application more concise and stable. Figures 1 to 6 As shown, optionally, the air guide member 2 includes an air guide block 23, the air guide block 23 is connected to the side wall of the adsorption block 1, and the air guide channel 21 is formed on the air guide block 23. For example, the air guide channel 21 is cut and formed on the air guide block 23.

[0072] Of course, the air guide 2 may also adopt other structures. Figure 7 As shown, in another embodiment, the air guide member 2 includes a mounting bracket 24 and at least two (for example, three in the figure) inclined air guide plates 25, wherein: the mounting bracket 24 is connected to the side wall of the adsorption block 1. At least two air guide plates 25 are installed on the mounting bracket 24 at intervals along the direction of the compressed gas flowing on the adsorption surface of the adsorption block 1, and an air guide channel 21 is formed between two adjacent air guide plates 24. In actual use, the number of air guide plates 24 can be increased or decreased as needed to implement flexible adjustment of the number and width of the air guide channels 21.

[0073] like Figures 8 to 9 As shown, in another embodiment, the air guide member 2 includes a connecting plate 26 and a first air guide plate 27, wherein: the connecting plate 26 is mounted on the side wall of the adsorption block 1. The first air guide plate 27 is connected to the connecting plate 26, and the lower surface of the first air guide plate 27 is connected to the adsorption surface of the adsorption block 1. At least one air guide channel 21 is provided on the first air guide plate 27. For example, Figure 8 An air guide channel 21 is provided on the first air guide plate 27. Fig. 9 The first air guide plate 27 is provided with two air guide channels 21. In order to facilitate processing and improve the strength of the first air guide plate 27, Figure 8 and Fig. 9 The air channels 21 in the embodiment are all discontinuous air channels. Figure 8 One air guide channel 21 is formed by combining two strip holes arranged at intervals. Of course, the air guide channel 21 can also be processed into a continuous air guide channel.

[0074] Since the lower surface of the first air guide plate 27 is connected to the adsorption surface of the adsorption block 1, part of the compressed air blown out from the first blowing gap leaves the adsorption surface of the adsorption block 1 and flows along the lower surface of the first air guide plate 27. During the flow, part of the compressed air is blown out through the air guide duct 21, and the remaining compressed air is finally blown out through the end of the first air guide plate 27.

[0075] Continue to refer Figure 7 and Figure 8 As shown, optionally, the air guide 2 further includes a second air guide plate 28, which is connected to the first air guide plate 27, and the second air guide plate 28 is tilted upward relative to the first air guide plate 27, and part of the compressed air will flow along the second air guide plate 28 toward a direction away from the plane where the adsorption surface of the adsorption block 1 is located. After the remaining compressed air that has not been blown out of the air guide 21 leaves the first air guide plate 27, it is blown upward at an angle under the guidance of the second air guide plate 28, thereby further reducing the interference with the sheet outside the adsorption area.

[0076] like Figure 4 , Figure 7 and Figure 8 As shown, in order to facilitate the disassembly and assembly of the air guide member 2. Optionally, a mounting hole 22 is provided on the air guide member 2, and the air guide member 2 is fixedly mounted on the side of the adsorption block 1 through the mounting hole 22.

[0077] like Figures 10 to 13 As shown, optionally, the adsorption block 1 includes a base 11, a core 13 and a solenoid valve 14, wherein: the bottom of the base 11 is provided with a mounting groove 12 extending along a first direction, the core 13 is embedded in the mounting groove 12, the first air cavity is provided on the core 13, and a first blowing gap 15 is formed between the first side edge of the core 13 and the base 11. An air supply path 16, a first air blowing path 17 and an air release path 18 extending along the first direction are provided in the base 11, wherein the air supply path 16 is used to connect to a compressed air source, the first air blowing path 17 is connected to the first air cavity, and the air release path 18 has an air release port connected to the outside.

[0078] The solenoid valve 14 is disposed on the base 11, and the air supply path 16, the first air blowing path 17, and the air release path 18 are respectively connected to the valve ports of the solenoid valve 14. The solenoid valve 14 is configured to connect the air supply path 16 and the first air blowing path 17, and block the first air blowing path 17 and the air release path 18, so that the compressed air enters the first air cavity through the air supply path 16 and the first air blowing path 17 in sequence.

[0079] The solenoid valve 14 is further configured to block the air supply path 16 and the first air blowing path 17 , and connect the first air blowing path 17 and the air release path 18 , so that the compressed air in the first air blowing path 17 is discharged through the air release port of the air release path 18 .

[0080] The air guide member 2 is fixedly connected to the first side wall of the base 11 .

[0081] The optional working process of the adsorption unit 10 is as follows:

[0082] When it is necessary to implement suction of the sheet located under the adsorption unit 10, the solenoid valve 14 is controlled to connect the air supply path 16 and the first air blowing path 17, block the first air blowing path 17 and the air release path 18, and control the air supply of the compressed air source, so that the compressed air supplied by the compressed air source enters the first air cavity through the air supply path 16 and the first air blowing path 17 in turn, and is finally blown out at high speed to the first side of the base 11 through the first air blowing slit 15, thereby generating a suction area on the adsorption surface of the adsorption block 1 to implement suction of the sheet.

[0083] Part of the compressed air blown out at high speed toward the first side of the base 11 enters the air duct 21 along the adsorption surface of the adsorption block 1. The compressed air flows in the air duct 21 in a direction away from the plane where the adsorption surface of the adsorption block 1 is located and is blown out from the air outlet end of the air duct 21, thereby avoiding interference with the sheet outside the adsorption area.

[0084] When it is necessary to end the suction of the sheet, the compressed air source is controlled to stop supplying air. At the same time, the solenoid valve 14 is controlled to block the air supply path 16 and the first blowing air path 17, and connect the first blowing air path 17 and the deflation air path 18, so that the residual compressed air in the first blowing air path 17 is quickly discharged through the deflation port of the deflation air path 18, thereby making the adsorption area of ​​the adsorption surface of the adsorption block 1 disappear quickly.

[0085] Since the main gas circuits of the adsorption block 1 are arranged in the base 11, only one external pipeline is needed to connect the gas supply circuit 16 with the external compressed gas source, which is convenient for installation and further reduces the interference to the sheet outside the adsorption area.

[0086] like Fig.12 and Fig.14 As shown, optionally, the core body 13 includes a gasket 116 and a core plate 117, wherein the gasket 116 is arranged between the base 11 and the core plate 117, a first side edge of the gasket 116 is provided with a plurality of first grooves 118 along a first direction, and the base 11 and the core plate 117 block the plurality of first grooves 118 from the upper and lower sides to form a plurality of first air cavities. Fig.14In the illustrated embodiment, four first grooves 118 are provided on the first side edge of the gasket 116 , and correspondingly, four first air cavities are formed in the core body 13 .

[0087] By configuring the core body 13 to include a gasket 116 and a core plate 117 and providing a plurality of first grooves 118 on the first side edge of the gasket 116 , a plurality of first air cavities can be formed after the gasket 116 and the core plate 117 are installed in the installation grooves in the base 11 .

[0088] In order to facilitate the processing of the mounting groove 12 and the core plate 117, the mounting groove 12 is optionally a V-shaped groove, and the mounting groove 12 has a first inclined surface inclined downward toward the first side of the base 11, and a second inclined surface inclined downward toward the second side of the base. The core plate 117 has a third inclined surface matching the first inclined surface, and a fourth inclined surface matching the second inclined surface. Correspondingly, the third inclined surface and the first inclined surface block a plurality of first grooves 118 from both upper and lower sides to form a plurality of first air cavities.

[0089] In order to achieve the communication between the first air cavity and the first blowing air path 17, the compressed air in the first blowing air path 17 can flow into the first air cavity at a high speed. Fig.12 As shown, a plurality of first blowing holes 110 are provided in the base 11, and each first air cavity is connected to the first blowing air path 17 via at least one first blowing hole 110. For example, Fig.12 In the illustrated embodiment, each first air cavity is connected to the first air blowing path 17 via two first air blowing holes 110 .

[0090] like Fig.10 As shown, optionally, the first air blowing path 17 extends along the first direction. A plurality of first blocking holes 111 communicating with the first air blowing path 17 are arranged on the base 11 along the first direction, and the first blocking holes 111 are used to insert the first blocking members to block the first air blowing path 17 from the corresponding position, and the first blocking holes 111 into which the first blocking members are not inserted are inserted with the first blocking members for blocking the first blocking holes 111.

[0091] For example, Fig.10 In the illustrated embodiment, three first blocking holes 111 are provided on the base 11 along the first direction, and for the convenience of description, they are respectively marked as the first blocking hole 111a, the first blocking hole 111b, and the first blocking hole 111c. In an application scenario, the first blocking member is inserted into the first blocking hole 111b at the middle position, and the first blocking hole 111a and the first blocking hole 111c are both inserted with the first blocking member. At this time, the first blowing air path 17 is blocked at the position corresponding to the first blocking hole 111b, so the compressed air can only enter the gap between the first blocking hole 111b and one end of the base 11 (such as Fig.10Finally, a negative pressure area is generated at the corresponding position at the bottom of the base 11 in the first blowing air path 17 between the B end in the middle.

[0092] That is to say, by inserting the first blocking piece into a suitable first blocking hole 111, the length of the adsorption area of ​​the adsorption unit 10 in the first direction can be adjusted, and the amount of compressed air used can be reduced while ensuring the adsorption effect of the adsorption unit 10 on the sheet, and the impact on other surrounding sheets can be reduced. Optionally, the three first blocking holes 111 are all threaded holes, and the first blocking piece is a long screw, which extends into the first air blowing path 17 and abuts against the inner wall of the first air blowing path 17, thereby blocking the first air blowing path 17. The first blocking piece is a short screw, which only blocks the first blocking hole 111 to prevent gas from leaking from the first blocking hole 111, and the short screw will not abut against the inner wall of the first air blowing path 17.

[0093] like Fig.11 and Fig.13 As shown, optionally, a second air cavity is further provided on the core 13, and a second air blowing slit 112 communicating with the second air cavity is formed between the second side edge of the core 13 and the base 11. A second air blowing path 113 is also provided in the base 11, wherein the second air blowing path 113 is communicated with the first air blowing path 17. When the solenoid valve 14 connects the air supply path 16 and the first air blowing path 17, the compressed air supplied by the air source also enters the second air cavity through the air supply path 16, the first air blowing path 17 and the second air blowing path 113 in sequence, and is blown out at high speed to the second side of the base 11 through the second air blowing slit 112.

[0094] That is to say, when the sheet is being sucked, the first blowing slit 15 and the second blowing slit 112 on both sides of the core body 13 blow gas at high speed toward the first side and the second side of the base 11 respectively, so that the adsorption forces on both sides of the adsorption area formed on the adsorption surface of the adsorption block 1 are balanced, thereby improving the stability of adsorption of the sheet.

[0095] like Fig.14 As shown, a plurality of second grooves 119 are provided along the first direction at the second side edge of the gasket 116 , and the base 11 and the core plate 117 block the plurality of second grooves 119 from both upper and lower sides to form a plurality of second air cavities. Fig.14 In the illustrated embodiment, four second grooves 119 are also provided on the second side edge of the gasket 116 , and correspondingly, four second air cavities are formed in the core body 13 .

[0096] like Fig.12 As shown, optionally, a plurality of second blowing holes 114 are provided in the base 11, and each second air cavity is connected to the second blowing air path 113 via at least one second blowing hole 114. For example, Fig.12In the illustrated embodiment, each second air cavity is connected to the second air blowing path 113 via two second air blowing holes 114 .

[0097] Optionally, the second blowing air path 113 extends along the first direction. Fig.10 As shown, a plurality of second blocking holes 115 connected to the second blowing air path 113 are provided on the base 11 along the second direction. The second blocking holes 115 are used to insert second blocking pieces to block the second blowing air path 113 from corresponding positions. Second blocking pieces for blocking the second blocking holes 115 are inserted into the second blocking holes 115 into which the second blocking pieces are not inserted.

[0098] Similarly, the second blocking hole 115 is a threaded hole. Optionally, the second blocking member is a long screw, which can extend into the second air blowing path 113 and abut against the inner wall of the second air blowing path 113, thereby blocking the second air blowing path 113. The second blocking member is a short screw, which only blocks the second blocking hole 115 to prevent gas from leaking from the second blocking hole 115. The short screw will not abut against the inner wall of the second air blowing path 113. The function of the second blocking hole 115 is the same as that of the first blocking hole 111 in the previous embodiment, and will not be repeated here.

The conveyor belt 30 is used to transport the sheet body adsorbed on the conveyor belt 30.

[0100] Through the cooperation of the adsorption unit 10 and the conveyor belt 30 , the sheet picking assembly 100 provided in the embodiment of the present application can absorb the sheet under the sheet picking assembly 100 and can convey the absorbed sheet.

[0101] The present application also provides a sheet conveying device, such as Fig.15 As shown, the sheet conveying device in the embodiment of the present application includes a sheet picking assembly 100, a first upper adsorption conveying assembly 200, a second upper adsorption conveying assembly 300 and a sheet conveying line 400 provided in any of the above embodiments, wherein: the conveying direction of the sheet picking assembly 100 is perpendicular to the conveying direction of the sheet conveying line 400.

[0102] The first upper suction conveyor assembly 200 is located at the first side of the film pickup assembly, and one end of the first upper suction conveyor assembly 200 is butted against the first end of the film pickup assembly 100. The second upper suction conveyor assembly 300 is located at the second side of the film pickup assembly 100, and one end of the second upper suction conveyor assembly 300 is butted against the second end of the film pickup assembly 100. The conveyor belt of the film pickup assembly 100 is configured to suck up the film on the film body conveying line 400 and convey it toward the first side, the first upper suction conveyor assembly 200 is used to receive the film and convey it to the first station, or the first upper suction conveyor assembly 200 is configured to convey the film at the first station to the film pickup assembly 100, and the film pickup assembly 100 is configured to convey the received film to the film body conveying line 400. The conveyor belt of the sheet picking assembly 100 is also configured to convey the sucked sheet toward the second side. The second upper adsorption conveying assembly 300 is used to receive the sheet and convey the sheet to the second workstation, or the second upper adsorption conveying assembly 300 is configured to convey the sheet from the second workstation to the sheet picking assembly 100. The sheet picking assembly 100 is configured to convey the received sheet to the sheet conveying line 400. The compressed air flowing to the air outlet end of the air duct of the sheet picking assembly 100 is blown out toward the top or diagonally above the sheet conveying line 400.

[0103] The sheet conveying device in the embodiment of the present application can realize the diversion conveying and the convergence conveying of the sheet to meet various processing requirements of the sheet. Among them, the diversion conveying is: the sheet sucked from the lower station of the sheet taking assembly 100 (for example, the unloading station of the sheet conveying line 400) is conveyed to the first station and the second station respectively.

[0104] In order to ensure that the sheet picking assembly 100 can stably suck up the sheet on the sheet conveying line 400, or ensure that the sheet picking assembly 100 can stably release the sheet to the sheet conveying line 400, the adsorption surface of the adsorption block 1 in the sheet picking assembly 100 needs to be set parallel to the conveying surface of the sheet conveying line 400, so most of the compressed gas blown out from the first blowing slit 15 of the adsorption block 1 will be blown out along the adsorption surface in a direction parallel to the sheet conveying line 400, which is bound to blow toward the adjacent sheet conveying line 400.
