[0037] like Figure 1-Figure 4 As shown, in the first aspect of an embodiment of the present application, a conveying device 100 is provided, comprising a first conveying mechanism 1 and a second conveying mechanism 2; the first conveying mechanism 1 comprises a first conveyor belt 11 and a first variable distance component 12, the first conveyor belt 11 moves along the X direction, and the first variable distance component 12 is arranged on one side of the first conveyor belt 11; the second conveying mechanism 2 comprises a second conveyor belt 21 and a second variable distance component 22, the first conveyor belt 11 and the second conveyor belt 21 are arranged adjacent to each other along the Y direction, and the second variable distance component 22 is arranged on the side of the second conveyor belt 21 away from the first conveyor belt 11; the first variable distance component 12 is used to adjust the distance between two adjacent materials 200 located on the first conveyor belt 11, and the second variable distance component 22 is used to adjust the distance between two adjacent materials 200 located on the second conveyor belt 21, and can guide the materials 200 on the second conveyor belt 21 to the first conveyor belt 11.

[0038] like Figure 1-Figure 4 As shown, the conveying device 100 includes a first conveying mechanism 1 and a second conveying mechanism 2 .

[0039] Among them, the first conveying mechanism 1 includes a first conveyor belt 11 and a first variable distance component 12; the first conveyor belt 11 is used to convey the material 200, and the first conveyor belt 11 moves along the X direction, so that the material 200 can be transferred in the X direction. The first variable distance component 12 is arranged on one side of the width direction of the first conveyor belt 11, and the width direction of the first conveyor belt 11 is the same as the Y direction. When the material 200 is placed on the first conveyor belt 11, the distance between two adjacent materials 200 is relatively close. Through the first variable distance component 12, the distance between two adjacent materials 200 can be increased.

[0040] The second conveying mechanism 2 includes a second conveyor belt 21 and a second variable pitch assembly 22; the second conveyor belt 21 is used to convey the material 200, and the second conveyor belt 21 moves along the X direction, so that the material 200 can be transferred in the X direction; the second conveyor belt 21 is arranged adjacent to the first conveyor belt 11 along the Y direction, and the second conveyor belt 21 is located on the side of the first conveyor belt 11 away from the first variable pitch assembly 12; the second variable pitch assembly 22 is arranged on one side of the width direction of the second conveyor belt 21, the width direction of the second conveyor belt 21 is the same as the Y direction, and the second variable pitch assembly 22 is located on the side of the second conveyor belt 21 away from the first conveyor belt 11; when the material 200 is placed on the second conveyor belt 21, the distance between two adjacent materials 200 is relatively close, and the second variable pitch assembly 22 can increase the distance between two adjacent materials 200.

[0041] To further illustrate, the material 200 on the first conveyor belt 11 increases the distance between two adjacent materials 200 through the first variable distance component 12, and the material 200 on the second conveyor belt 21 increases the distance between two adjacent materials 200 through the second variable distance component 22, and the second variable distance component 22 can play a guiding role to guide the material 200 on the second conveyor belt 21 to the first conveyor belt 11, so that a material 200 on the second conveyor belt 21 can be correspondingly inserted into the gap between two adjacent materials 200 on the first conveyor belt 11, thereby realizing the merging of the material 200 on the second conveyor belt 21 and the material 200 on the first conveyor belt 11 on the first conveyor belt 11.

[0042] In the embodiment of the present application, the material 200 located on the second conveying mechanism 2 can be merged into the first conveying mechanism 1 through the first variable distance component 12 and the second variable distance component 22, so that the material 200 is moved along the X direction through the first conveyor belt 11 to move it to a preset position, thereby realizing the automatic merging of the material 200 onto the first conveyor belt 11, thereby improving the conveying efficiency and reducing labor costs.

[0043] In one embodiment, the second variable pitch assembly 22 includes a second screw rod 23, and the second screw rod 23 can be tilted in the XY plane, and along the moving direction of the second conveyor belt 21, the second screw rod 23 gradually approaches the first conveyor belt 11; or, along the moving direction of the second conveyor belt 21, the outer diameter of the second screw rod 23 gradually increases. In the above two embodiments, the second variable pitch assembly 22 can achieve a guiding effect.

[0044] In another embodiment, the conveying device further includes a guiding mechanism, which may be a mechanical clamp or a pinhole suction cup to transfer the material 200 on the second conveyor belt 21 to the gap between two adjacent materials 200 on the first conveyor belt 11 .

[0045] In an optional embodiment, the first variable pitch assembly 12 includes a first screw rod 13, which is arranged on one side of the first conveyor belt 11, and the outer wall of the first screw rod 13 is formed with a first spiral groove 14 along the X direction; the conveying device 100 also includes a driving mechanism 3, and the driving mechanism 3 can drive the first screw rod 13 to rotate around the axis of the X direction.

[0046] like Figure 1 and Figure 2 As shown, the first variable pitch assembly 12 includes a first screw rod 13, which is arranged on one side of the first conveyor belt 11, and the length direction of the first screw rod 13 is the same as the moving direction of the first conveyor belt 11, that is, the length direction of the first screw rod 13 is the X direction; a first spiral groove 14 is formed on the outer wall of the first screw rod 13, and the first spiral groove 14 is spirally arranged along the length direction of the first screw rod 13, and the first spiral groove 14 extends from one end to the other end along the length direction of the first screw rod 13; the conveying device 100 also includes a driving mechanism 3, and the driving mechanism 3 can drive the first screw rod 13 to rotate around the axis of the X direction, so that the first spiral groove 14 can rotate around the axis of the X direction. When the material 200 is placed on the first conveyor belt 11 and moves along the X direction, when the material 200 passes through the first spiral rod 13, the first spiral groove 14 guides the material 200, so that the material 200 moves along the X direction through the first spiral groove 14, thereby increasing the distance between the materials 200 and the materials 200, and realizing the variable distance between the materials 200 and the materials 200. The structure is simple and can quickly adjust the distance between the materials 200 and the materials 200.

[0047] In an optional embodiment, the second variable pitch assembly 22 includes a second screw rod 23, which is arranged on the side of the second conveyor belt 21 away from the first conveying mechanism 1, and the outer wall of the second screw rod 23 is formed with a second spiral groove 24 along the X direction, and the driving mechanism 3 can drive the second screw rod 23 to rotate around the axis of the X direction.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the second variable pitch assembly 22 includes a second screw rod 23, which is arranged on the side of the second conveyor belt 21 away from the first conveyor belt 11, and the length direction of the second screw rod 23 is the same as the moving direction of the second conveyor belt 21, that is, the length direction of the second screw rod 23 is the X direction; a second spiral groove 24 is formed on the outer wall of the second screw rod 23, and the second spiral groove 24 is spirally arranged along the length direction of the second screw rod 23, and the second spiral groove 24 extends from one end to the other end along the length direction of the second screw rod 23; the driving mechanism 3 can also drive the second screw rod 23 to rotate around the axis of the X direction, so that the second spiral groove 24 can rotate around the axis of the X direction. When the material 200 is placed on the second conveyor belt 21, the material 200 moves along the X direction. When the material 200 passes through the second spiral rod 23, the second spiral rod 23 will guide the material 200, so that the material 200 moves along the X direction through the second spiral groove 24 to increase the distance between two adjacent materials 200, thereby realizing the variable distance between the materials 200 and 200, thereby facilitating the transfer of the material 200 on the second conveyor belt 21 to the first conveyor belt 11, and being able to be inserted into the gap between two adjacent materials 200.

[0049] In an optional implementation, the pitch of the first spiral groove 14 is smaller than the pitch of the second spiral groove 24 .

[0050] Among them, the first spiral groove 14 can be understood as a spiral line, and the second spiral groove 24 can also be understood as a spiral line; the pitch of the first spiral groove 14 is smaller than the pitch of the second spiral groove 24, so that after the material 200 on the first conveyor belt 11 passes through the first spiral rod 13 and the material 200 on the second conveyor belt 21 passes through the second spiral rod 23, the distances between the materials 200 and the materials 200 are different, and in the Y direction, the material 200 on the first conveyor belt 11 passes through the first spiral rod 13 and the material 200 on the second conveyor belt 21 passes through the second spiral rod 23 and is staggered, so that the material 200 on the second conveyor belt 21 can be inserted into the gap between two adjacent materials 200 on the first conveyor belt 11.

[0051] In an optional embodiment, in the Y direction, the first screw rod 13 at least partially extends into the first conveyor belt 11, and in the Z direction, the first screw rod 13 is located above the first conveyor belt 11; and / or in the Y direction, the second screw rod 23 at least partially extends into the second conveyor belt 21, and in the Z direction, the second screw rod 23 is located above the second conveyor belt 21.

[0052] In a specific implementation, in the Y direction, the first screw rod 13 at least partially extends into the first conveyor belt 11 , and in the Z direction, the first screw rod 13 is located above the first conveyor belt 11 .

[0053] In another specific embodiment, in the Y direction, the second screw rod 23 at least partially extends into the second conveyor belt 21 , and in the Z direction, the second screw rod 23 is located above the second conveyor belt 21 .

[0054] In another specific embodiment, in the Y direction, the first screw rod 13 at least partially extends into the first conveyor belt 11, and the second screw rod 23 at least partially extends into the second conveyor belt 21; in the Z direction, the first screw rod 13 is located above the first conveyor belt 11, and the second screw rod 23 is located above the second conveyor belt 21. This embodiment is taken as an example for description. In the Y direction, the first screw rod 13 at least partially extends into the first conveyor belt 11. In other words, the first screw rod 13 partially overlaps with the first conveyor belt 11 in the Y direction. When the width of the first conveyor belt 11 is greater than the outer diameter of the first screw rod 13, the first screw rod 13 can also fully extend into the first conveyor belt 11, so that the material 200 located on the first conveyor belt 11 can pass through the first spiral groove 14 of the first screw rod 13, thereby adjusting the distance between two adjacent materials 200; in the Z direction, the first screw rod 13 is located above the first conveyor belt 11, so that the first screw rod 13 can extend into the first conveyor belt 11 in the Y direction, and the first conveyor belt 11 does not need to provide avoidance space for it. The structure is simple and easy to install. In the Y direction, the second screw rod 23 at least partially extends into the second conveyor belt 21. In other words, the second screw rod 23 partially overlaps with the second conveyor belt 21 in the Y direction. When the width of the second conveyor belt 21 is greater than the outer diameter of the second screw rod 23, the second screw rod 23 can also fully extend into the second conveyor belt 21, so that the material 200 on the second conveyor belt 21 can pass through the second spiral groove 24 of the second screw rod 23 to adjust the distance between two adjacent materials 200; in the Z direction, the second screw rod 23 is located above the second conveyor belt 21, so that the second screw rod 23 can extend into the second conveyor belt 21 in the Y direction, and the second conveyor belt 21 does not need to provide avoidance space for it. The structure is simple and easy to install.

[0055] Preferably, the distance between the first spiral rod 13 and the first conveyor belt 11 in the Z direction is smaller than the height of the material 200, which can avoid the material 200 from being unable to contact the first spiral groove 14 on the first conveyor belt 11; the distance between the second spiral rod 23 and the second conveyor belt 21 in the Z direction is smaller than the height of the material 200, which can avoid the material 200 from being unable to contact the second spiral groove 24 on the second conveyor belt 21.

[0056] In an optional embodiment, along the moving direction of the second conveyor belt 21 , the outer diameter of the second screw rod 23 gradually increases, and in the Y direction, the second screw rod 23 extends into the second conveyor belt 21 and gradually approaches the first conveyor belt 11 .

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, along the moving direction of the second conveyor belt 21, that is, in the length direction of the second screw rod 23, the outer diameter of the second screw rod 23 gradually increases, and in the Y direction, the second screw rod 23 gradually approaches the direction of the first conveyor belt 11. Therefore, after the material 200 passes through the second spiral groove 24 of the second screw rod 23, the material 200 will gradually approach the first conveyor belt 11, so as to transfer the material 200 on the second conveyor belt 21 to the first conveyor belt 11. Therefore, the second screw rod 23 also plays a guiding role.

This can not only make the first screw rod 13 and the second screw rod 23 rotate synchronously, but also save installation space.
