[0048] The present invention provides a material conveying mechanism, which can smoothly and reliably convey materials, including but not limited to silicon wafers, sheets, etc.

[0049] like Figures 1 to 3 As shown, the material conveying mechanism provided by the embodiment of the present invention includes:

[0050] Base 1;

[0051] A conveying assembly 2 is provided on the base 1 and includes a conveying belt 21 and a first movable member 22 abutting against the conveying belt 21. The first movable member 22 is capable of extending and contracting along the conveying direction of the conveying belt 21 and moving between a first position and a second position. The first movable member 22 has a first adsorption portion for adsorbing material on the conveying belt 21.

[0052] The conveying assembly 2 further includes a second movable member 23, which is movably disposed on the base 1 and can move between the second position and a third position. The second movable member 23 has a second adsorption portion, which is used to adsorb the material on the conveyor belt 21.

[0053] When the first movable member 22 is extended, the first movable member 22 is located at the first position, and the second movable member 23 is located at the second position; when the first movable member 22 is retracted, the first movable member 22 is located at the second position, and the second movable member 23 is located at the third position.

[0054] like Figures 1 to 3As shown, the material conveying mechanism provided by the embodiment of the present invention includes a base 1 and a conveying assembly 2. The conveying assembly 2 can be disposed on the base 1, that is, the base 1 can be used to mount and support the conveying assembly 2, thereby improving the structural stability of the material conveying mechanism. The conveying assembly 2 includes a conveyor belt 21, which can be a belt, and can realize material conveyance via the conveyor belt 21.

[0055] like Figures 1 to 3 As shown, in the embodiment of the present invention, a first movable part 22 is provided on the side of the conveyor belt 21 close to the base 1. The first movable part 22 can be extended and retracted along the conveying direction of the conveyor belt 21, that is, the first movable part 22 can be extended or retracted along the conveying direction of the conveyor belt 21, thereby facilitating the insertion of the material conveyed on the conveyor belt 21 into the loading part 300, and also improving the loading efficiency of the material loading device using the material conveying mechanism.

[0056] In addition, the first movable part 22 is arranged on the side of the conveyor belt 21 close to the base 1, so that the first movable part 22 can be against the conveyor belt 21, and the first movable part 22 can also be used to support the conveyor belt 21, thereby improving the structural stability of the material conveying mechanism and saving the separate arrangement of the support structure.

[0057] The conveyor assembly 2 further includes a second movable member 23, which is movably mounted on the base 1. The second movable member 23 cooperates with the first movable member 22 to ensure smooth and reliable material conveyance. Furthermore, the second movable member 23 provides good support for the conveyor belt 21 thereon.

[0058] During the process of the first movable part 22 extending and retracting along the conveying direction of the conveyor belt 21, the first movable part 22 can move between the first position and the second position, so that the first movable part 22 can extend into the loading part 300 to realize the loading of materials; the corresponding second movable part 23 can move between the second position and the third position, so that it can cooperate with the first movable part 22 to realize continuous conveying of materials.

[0059] The first position and the second position are both located on the conveying path of the conveyor belt 21 , the first position is close to the loading portion 300 , and the third position is away from the loading portion 300 ; the third position is staggered from the conveying path of the conveyor belt 21 .

[0060] Specifically, if Figure 2 and Figure 3As shown, when the first movable member 22 is extended, the first movable member 22 is located in the first position and the second movable member 23 is located in the second position. The second movable member 23 can cooperate with the first movable member 22 to achieve smooth conveying of materials. At this time, the second movable member 23 and the first movable member 22 can jointly support the conveyor belt 21. When the first movable member 22 is retracted, the first movable member 22 is located in the second position and the second movable member 23 is located in the third position. This allows the second movable member 23 to avoid interference with the movement of the first movable member 22, thereby facilitating continuous conveying of materials.

[0061] On this basis, an embodiment of the present invention provides a first adsorption portion on the first movable part 22 and a second adsorption portion on the second movable part 23. The first adsorption portion and the second adsorption portion are both used to form adsorption on the material on the conveyor belt 21, so that during the process of the first movable part 22 contracting along the conveying direction of the conveyor belt 21, the first adsorption portion and the second adsorption portion can be used to adsorb the material on the conveyor belt 21, thereby reducing the risk of abnormal falling or displacement of the material.

[0062] Optionally, the first position and the second position are both located on the conveying path of the conveyor belt 21 , and the third position is staggered from the conveying path of the conveyor belt 21 .

[0063] Specifically, the embodiment of the present invention sets the first position and the second position to be located on the conveying path of the conveyor belt 21, the first position is close to the loading part 300, and the third position is far away from the loading part 300; the third position is staggered with the conveying path of the conveyor belt 21, so that during the process of the first movable part 22 contracting along the conveying direction of the conveyor belt 21, the second movable part 23 can cooperate with the first movable part 22 to realize continuous conveying of materials.

[0064] Optionally, the first adsorption portion includes a second through hole 221 and a first chamber, the second through hole 221 is located on the side of the first movable part 22 away from the base 1, the first chamber is located in the first movable part 22, and the second through hole 221 is connected to the first chamber, and the second through hole 221 and the first chamber are used to form adsorption on the material on the conveyor belt 21.

[0065] like Figure 1 and Figure 2 As shown, the first adsorption portion of the embodiment of the present invention may include a second through hole 221 and a first chamber. The second through hole 221 and the first chamber cooperate to adsorb the material on the conveyor belt 21.

[0066] Specifically, at least one second through hole 221 is formed on the side of the first movable member 22 adjacent to the conveyor belt 21. The first through hole 211 on the conveyor belt 21 can communicate with the first chamber within the first movable member 22 via the second through hole 221, thereby adjusting the pressure in the first chamber to adjust the material conveying effect. The first through hole 211 and the second through hole 221 can be arranged opposite each other to facilitate communication between the first through hole 211 and the first chamber within the first movable member 22.

[0067] Optionally, the second adsorption portion includes a third through hole 231 and a second chamber, the third through hole 231 is located on the side of the second movable part 23 away from the base 1, the second chamber is located in the second movable part 23, and the third through hole 231 and the second chamber are connected, and the third through hole 231 and the second chamber are used to form adsorption on the material on the conveyor belt 21.

[0068] like Figure 1 As shown, the second adsorption portion of the embodiment of the present invention may include a third through hole 231 and a second chamber. The third through hole 231 and the second chamber cooperate to adsorb the material on the conveyor belt 21.

[0069] Specifically, at least one third through hole 231 is formed on a side of the second movable member 23 away from the base 1. The first through hole 211 on the conveyor belt 21 can communicate with the second chamber in the second movable member 23 through the third through hole 231, thereby adjusting the pressure in the second chamber to adjust the material conveying effect. The first through hole 211 and the third through hole 231 can be arranged opposite each other to facilitate communication between the first through hole 211 and the second chamber in the second movable member 23.

[0070] Optionally, during the process of the conveyor belt 21 conveying materials, the pressure of the first chamber and the pressure of the second chamber are both lower than the external pressure.

[0071] Specifically, during the process of conveying materials by the conveyor belt 21, the pressure of the first chamber and the pressure of the second chamber can be adjusted to be lower than the external pressure, that is, the external pressure is greater than the pressure of the first chamber and the pressure of the second chamber, so that the material can be adsorbed on the conveyor belt 21, reducing the risk of abnormal falling or dislocation or displacement of the material, thereby improving the conveying stability and reliability of the material conveying mechanism.

[0072] Optionally, the pressure of the first chamber is equal to the pressure of the second chamber.

[0073] Specifically, the embodiment of the present invention can set the pressure of the first chamber and the pressure of the second chamber to be equal, so that the adsorption capacity of the first movable part 22 for the material is basically the same as the adsorption capacity of the second movable part 23 for the material, thereby facilitating the smooth and uniform transportation of the material and reducing the risk of abnormal falling or dislocation of the material.

[0074] In addition, setting the pressure of the first chamber to be equal to the pressure of the second chamber also facilitates synchronous control of the pressure of the first chamber and the pressure of the second chamber through external air pumps and other structures, reducing the difficulty of controlling the pressure of the first chamber and the pressure of the second chamber, and also facilitates adjustment of the conveying effect of the material conveying mechanism.

[0075] In another embodiment, the pressure of the first chamber and the pressure of the second chamber can be set to be different. For example, the pressure of the first chamber can be set to be lower than the pressure of the second chamber. That is, the pressure of the second chamber is higher, which can improve the conveying reliability of the material during the initial conveying stage on the conveyor belt 21. The pressure of the first chamber is lower, which can facilitate the first movable member 22 to extend into the loading portion 300 to achieve convenient loading of materials. In this case, the pressure of the first chamber and the pressure of the second chamber are both lower than the external pressure, so that the material can be adsorbed on the conveyor belt 21 during the entire conveying process.

[0076] Optionally, a first through hole 211 is formed on the conveyor belt 21, and the first through hole 211 is connected to the first chamber through the second through hole 221;

[0077] The first through hole 211 is connected to the second chamber through the third through hole 231 .

[0078] like Figures 1 to 3 As shown, in the embodiment of the present invention, one or more first through holes 211 can be opened on the conveyor belt 21, and one or more second through holes 221 can be opened on the first movable part 22. Any second through hole 221 is opposite to at least one first through hole 211, so that the first through hole 211 is fully connected with the first chamber in the first movable part 22, thereby improving the adsorption capacity of the first movable part 22 on the material transported on the conveyor belt 21.

[0079] Similarly, one or more third through holes 231 may be provided on the second movable part 23, and any third through hole 231 is opposite to at least one first through hole 211, so as to facilitate full communication between the first through hole 211 and the second chamber in the second movable part 23, thereby improving the adsorption capacity of the second movable part 23 on the material transported on the conveyor belt 21.

[0080] The specific number of the first through holes 211 on the conveyor belt 21 , the second through holes 221 on the first movable member 22 , and the third through holes 231 on the second movable member 23 must also take into account the strength requirements of the structure itself.

[0081] Optionally, the second movable member 23 includes a movable plate 232 and a first driving source 233, the movable plate 232 is movably connected to the base 1, the first driving source 233 is disposed on the base 1, the first driving source 233 is connected to the movable plate 232, and the third through hole 231 and the second chamber are both located on the movable plate 232;

[0082] When the first movable member 22 is extended, the first driving source 233 can drive the movable plate 232 to move to the second position; when the first movable member 22 is retracted, the first driving source 233 moves to the third position and avoids the second position.

[0083] like Figures 4 to 6 As shown, the second movable member 23 of the embodiment of the present invention may include a movable plate 232 and a first driving source 233. The movable plate 232 may be a rectangular plate, a circular plate or other irregularly shaped plates. The first driving source 233 includes but is not limited to a motor, a cylinder, etc.

[0084] The movable plate 232 is movably connected to the base 1. The first drive source 233 is disposed on the base 1 and is connected to the movable plate 232. This allows the movable plate 232 to move on the base 1 under the drive of the first drive source 233, thereby cooperating with the first movable member 22 to achieve smooth and reliable material conveying. The third through-hole 231 is located on the movable plate 232, and the second chamber is located within the movable plate 232. This allows the first through-hole 211 to communicate with the second chamber within the movable plate 232 via the third through-hole 231. The material conveying effect can be adjusted by adjusting the pressure in the second chamber.

[0085] Specifically, when the first movable member 22 is extended, the first movable member 22 is located in the first position, and the first driving source 233 can drive the movable plate 232 closer to the conveyor belt 21 to the second position to ensure support for the conveyor belt 21. At this time, the movable plate 232 cooperates with the first movable member 22 to achieve smooth and reliable conveying of materials. When the first movable member 22 is retracted, the first movable member 22 is located in the second position, and the first driving source 233 can drive the movable plate 232 away from the conveyor belt 21 to the third position, avoiding the second position, thereby preventing the movable plate 232 from interfering with the first movable member 22, thereby facilitating continuous conveying of materials.

[0086] Optionally, the second movable member 23 further includes a bracket 234 , the bracket 234 is disposed on the base 1 , and the first driving source 233 and the movable plate 232 are both disposed on the bracket 234 ;

[0087] The first driving source 233 includes a first sub-driving source 2331 and a second sub-driving source 2332 . The first sub-driving source 2331 and the second sub-driving source 2332 are used to drive the movable plate 232 to move in the vertical direction and the horizontal direction to approach or move away from the second position.

[0088] like Figures 4 to 6 As shown, the second movable member 23 of the embodiment of the present invention may further include a bracket 234, which is disposed on the base 1. The first driving source 233 and the movable plate 232 are both disposed on the bracket 234. That is, the bracket 234 is used to mount and support the first driving source 233 and the movable plate 232, which facilitates the arrangement of the first driving source 233 and the movable plate 232. Moreover, the movable plate 232 is movably disposed on the bracket 234, so that the movable plate 232 can be moved closer to or away from the conveyor belt 21 under the drive of the first driving source 233.

[0089] Specifically, if Figure 4 As shown, the first driving source 233 may include a first sub-driving source 2331 and a second sub-driving source 2332. The first sub-driving source 2331 is used to drive the movable plate 232 to move in a first direction, and the first direction is a vertical direction perpendicular to the conveying plane of the conveyor belt 21; the second sub-driving source 2332 is used to drive the movable plate 232 to move in a second direction, and the second direction is a horizontal direction on the conveying plane of the conveyor belt 21 and perpendicular to its conveying direction. The second direction is perpendicular to the first direction, so that the movable plate 232 can be driven by the first sub-driving source 2331 and the second sub-driving source 2332 to approach the conveyor belt 21 to the second position or move away from the conveyor belt 21 to the third position.

[0090] The first sub-driving source 2331 may be a motor, a cylinder, etc., and the second sub-driving source 2332 may also be a motor, a cylinder, etc. In addition, a guide rail or other guide member may be provided on the bracket 234. For example, the extending direction of the guide rail is the same as the movement direction of the movable plate 232, so that the movement of the movable plate 232 can be guided by the guide rail.

[0091] Optionally, the first movable part 22 includes a telescopic plate 222 and a second driving source 223, the telescopic plate 222 is movably connected to the conveyor belt 21, and the first chamber and the second through hole 221 are both located on the telescopic plate 222, the second driving source 223 is arranged on the base 1, the second driving source 223 is connected to the telescopic plate 222, and can drive the telescopic plate 222 to extend or retract.

The second driving source 223 is arranged on the base 1. The second driving source 223 is connected to the telescopic plate 222 and can drive the telescopic plate 222 to extend or retract, thereby realizing continuous loading of materials.

[0094] Among them, the first chamber and the second through hole 221 are both located on the telescopic plate 222, so that the first through hole 211 on the conveyor belt 21 can be connected to the first chamber in the telescopic plate 222 through the second through hole 221, so that the material conveying effect can be adjusted by adjusting the pressure of the first chamber.

[0095] Optionally, the first movable member 22 further includes a cover plate 224 , and the cover plate 224 is disposed on a side of the telescopic plate 222 close to the base 1 .

[0096] like Figure 7 As shown, in this embodiment of the present invention, the first movable member 22 may further include a cover plate 224. The cover plate 224 is disposed on the side of the telescopic plate 222 closest to the base 1, that is, the cover plate 224 is located between the telescopic plate 222 and the base 1. On the one hand, the cover plate 224 can enhance the support effect of the first movable member 22 on the conveyor belt 21; on the other hand, the cover plate 224 can also protect the telescopic plate 222, reducing the risk of foreign matter falling into the first chamber through the second through hole 221.

[0097] Furthermore, the cover plate 224 is provided with a plurality of fourth through holes 2241, through which the cover plate 224 can be connected to the telescopic plate 222. For example, the connection between the two can be achieved by common connection methods such as screws and bolts.

[0098] Optionally, the second through hole 221 is a waist-shaped hole.

[0099] like Figure 8 As shown, the second through hole 221 of the embodiment of the present invention may be a waist-shaped hole. By opening the waist-shaped hole on the telescopic plate 222 , the difficulty of opening holes and the number of holes on the telescopic plate 222 can also be reduced.
