[0016] Compared with the prior art, the beneficial effects of this application are:
[0017] The conveying device provided in the present application forms a relatively arranged load-bearing inclined plane on the conveyor belt, namely, a first inclined plane and a second inclined plane. When the conveying device conveys the substrate, the two side edges of the substrate are mounted on the first inclined plane and the second inclined plane, and the substrate is conveyed under the traction of the driving end. The first inclined plane and the second inclined plane of the conveying device are used to form a support structure with a slope, thereby realizing the clamping support of the side wall of the substrate. The substrate transported in this state only needs its edge, namely the side wall, to contact the first inclined plane and the second inclined plane at the same time, and there is no contact object on the upper and lower surfaces of the substrate. The contact area between the substrate and the conveying device is small, and the part in contact with the support structure is the side wall of the substrate, which does not affect the appearance quality of the substrate product.

[0029] Embodiment 1
[0030] See also Figures 1 to 5 As shown, the conveying device provided by the present application includes a first conveyor belt and a second conveyor belt. The first conveyor belt and the second conveyor belt are arranged at intervals, specifically arranged in parallel, and driven by the driving end, the first conveyor belt and the second conveyor belt run synchronously at the same speed, and can be used to transport the substrate 106.
[0031] The first conveyor belt has a first inclined surface, and the second conveyor belt has a second inclined surface. The first inclined surface and the second inclined surface are arranged opposite to each other to support the two side edges of the substrate 106. Specifically, the first conveyor belt includes a first bearing assembly 101 and a plurality of first supporting assemblies 104, and the second conveyor belt includes a second bearing assembly 102 and a plurality of second supporting assemblies 105. The first supporting assembly 104 is connected to the first bearing assembly 101 so that the first bearing assembly 101 drives the first supporting assembly 104 forward; and the supporting surfaces of the plurality of first supporting assemblies 104 jointly form a first inclined surface to support the substrate 106. The second supporting assembly 105 is connected to the second bearing assembly 102 so that the second bearing assembly 102 drives the second supporting assembly 105 forward; and the supporting surfaces of the plurality of second supporting assemblies 105 jointly form a second inclined surface to support the substrate 106. The substrate 106 is placed horizontally, and the two end edges of the substrate 106 can be overlapped on the first inclined surface and the second inclined surface respectively. The substrate 106 can be jointly supported by the first supporting assembly 104 and the second supporting assembly 105, which can improve stability. Moreover, in the solution of the present application, only the edge of the substrate 106 is in contact with the first inclined surface and the second inclined surface, and there is no touching object on the surface of the substrate 106. Compared with the solution in the prior art in which the substrate 106 is placed flat on the mesh chain, the solution of the present application reduces the contact area between the substrate 106 and the conveying device. While the substrate 106 is fully dried, the generation of imprints during the drying process of the substrate 106 can be avoided, thereby ensuring the quality of the substrate 106.
[0032] It should be noted that the specific structure of the support assembly (ie, the first support assembly and the second support assembly) of this embodiment is not limited, and the support assembly can be configured in a strip or sheet shape according to actual needs.
[0033] For example, in an optional solution of this embodiment, Figure 2 As shown, the first support component 104 is a strip structure, and the first support component 104 includes a first support rod 107. A plurality of first support rods 107 can jointly support the substrate 106, and the plurality of first support rods 107 are spaced apart along the conveying direction of the first supporting component 101 so that a larger flow gap 108 is formed between the plurality of first support rods 107, thereby facilitating the drying of the substrate 106.
[0034] In addition to the structure in which the first support components 104 are arranged at intervals as shown in the figure, the first support components 104 may also be arranged without intervals. For example, the first support components 104 may be arranged closely together, or the first support components 104 may be arranged as a whole plate structure, which can also form the first inclined surface.
[0035] Specifically, one end of the plurality of first support rods 107 is connected to the first bearing assembly 101, and the other end of the plurality of first support rods 107 is a first free end, and the first free end is inclined toward the inner bottom of the first bearing assembly 101, so that the upper surfaces of the plurality of first support rods 107 together form a first inclined plane. In other words, the first inclined plane is inclined toward the inner bottom of the first bearing assembly 101, so that the substrate 106 is located between the first bearing assembly 101 and the second bearing assembly 102 and in a downward position, which can reduce the space occupied by the device.
[0036] Similarly, the second support assembly 105 is a strip structure, and the second support assembly 105 includes a second support rod 109. Multiple second support rods 109 can jointly support the substrate 106, and the multiple second support rods 109 are spaced apart along the conveying direction of the second supporting assembly 102 so that a large flow gap 108 is formed between the multiple second support rods 109, which is beneficial to drying the substrate 106.
[0037] In addition to the structure in which the second support components 105 are arranged at intervals as shown in the figure, the second support components 105 may also be arranged without intervals. For example, the second support components 105 may be arranged closely together, or the second support components 105 may be arranged as a whole plate structure, which can also form the first inclined surface.
[0038] The first support assembly 104 and the second support assembly 105 can be configured to have the same structure or different structures according to actual conditions. For example, the first support assembly 104 and the second support assembly 105 are both configured to be strip-shaped or sheet-shaped, or one of the first support assembly 104 and the second support assembly is configured to be strip-shaped and the other is configured to be sheet-shaped.
[0039] Specifically, one end of the plurality of second support rods 109 is connected to the second bearing assembly 102, and the other end of the plurality of second support rods 109 is a second free end, and the second free end is inclined toward the inner bottom of the second bearing assembly 102, so that the upper surfaces of the plurality of second support rods 109 together form a second inclined plane. In other words, the second inclined plane is inclined toward the inner bottom of the second bearing assembly 102, so that the substrate 106 is located between the first bearing assembly 101 and the second bearing assembly 102 and in a downward position, which can reduce the space occupied by the device.
[0040] Preferably, multiple first support rods 107 are evenly arranged in parallel along the conveying direction of the first supporting assembly 101, so that the pressure borne by each first support rod 107 is equal, and the support for the substrate 106 is more stable. The equal flow gaps 108 also make the drying effect of various parts of the substrate 106 more uniform, avoiding the substrate 106 from falling from the larger flow gap 108 when the flow gaps 108 are unequal.
[0041] Similarly, multiple second support rods 109 are evenly arranged in parallel along the conveying direction of the second supporting assembly 102, so that the pressure borne by each second support rod 109 is equal. When the width of the flow gap is consistent, the support for the substrate 106 is more stable. The equal flow gap 108 also makes the drying effect of various parts of the substrate 106 more uniform, avoiding the substrate 106 from falling from the larger flow gap 108 when the width of the flow gap 108 is inconsistent.
[0042] The plurality of first support rods 107 are located in the same plane so that the first inclined surface formed by them is a flat plane. The plurality of second support rods 109 are located in the same plane so that the second inclined surface formed by them is a flat plane. When the substrate 106 overlaps the first inclined surface and the second inclined surface, the contact area between the linear side edge of the substrate 106 and the first inclined surface and the second inclined surface is small, and the first inclined surface and the second inclined surface are located at the edge of the substrate 106, thereby avoiding the generation of imprints during the transportation of the substrate 106, thereby ensuring the quality of the substrate 106.
[0043] In an optional solution of this embodiment, the first support assembly 104 further includes a first lap plate 111. The first lap plate 111 is located at one end of the first support rod 107 close to the first bearing assembly 101, and the first lap plate 111 is connected to the first bearing assembly 101. The board surface of the first lap plate 111 is connected to the first bearing assembly 101, which can increase the connection area to make the connection more reliable.
[0044] The second support assembly 105 further includes a second lap plate 113. The second lap plate 113 is located at one end of the second support rod 109 close to the second bearing assembly 102, and the second lap plate 113 is connected to the second bearing assembly 102. The plate surface of the second lap plate 113 is connected to the second bearing assembly 102, which can increase the connection area to make the connection more reliable.
[0045] like Figure 1 and Figure 2 As shown, the first load-bearing assembly 101 and the second load-bearing assembly 102 are both conveying chains, and the chain links 114 constituting the conveying chains are provided with inner curved plates 115. The first lap plate 111 is connected to the inner curved plate 115 of the first load-bearing assembly 101, and the second lap plate 113 is connected to the inner curved plate 115 of the second load-bearing assembly 102. Specifically, the plate surface of the inner curved plate 115 is arranged horizontally, and the inner curved plate 115 is provided with a connecting hole 118, and the first lap plate 111 and the second lap plate 113 are also provided with corresponding connecting holes 118, and the first lap plate 111 and the second lap plate 113 can be connected to the corresponding inner curved plates 115 by bolts.
[0046] In an optional scheme of this embodiment, in order to avoid damage to the substrate 106 when it is placed on the first support rod 107 and the second support rod 109, a first soft layer may be provided on at least the supporting side of the first support rod 107, and a second soft layer may be provided on at least the supporting side of the second support rod 109, that is, a soft layer may be provided on the supporting side (the side in contact with the substrate) of the first support rod 107 and the second support rod 109, or the first support rod 107 and the second support rod 109 may be integrally covered with a soft layer, so that the two end edges of the substrate 106 may overlap on the first soft layer and the second soft layer, which can reduce damage to the substrate 106 and increase friction, thereby preventing the substrate 106 from falling.
[0047] Specific as Figure 3 and Figure 4 As shown, a fluororubber sleeve 116 is sleeved on the outside of the first support rod 107, and a fluororubber sleeve 116 is sleeved on the outside of the second support rod 109, so that the operation of sleeve-mounting the fluororubber sleeve 116 is more convenient.
[0048] Embodiment 2
[0049] The conveying device in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.
[0050] In an optional solution of this embodiment, the conveying device also includes an anti-drop component, see Figure 3 and Figure 4 As shown, the anti-drop assembly includes a connecting rod 117, the first support rod 107 and the second support rod 109 are correspondingly arranged, one end of the connecting rod 117 is connected to the first free end of the first support rod 107, and the other end of the connecting rod 117 is connected to the second free end of the corresponding second support rod 109. The connecting rod 117 is used to connect the first support rod 107 and the second support rod 109 in a one-to-one correspondence, which can make the first inclined surface formed by the first support rod 107 and the second inclined surface formed by the second support rod 109 more stable, and prevent the positions of the first support rod 107 and the second support rod 109 from moving to affect the support effect on the substrate 106. And the connecting rod 117 can also play the role of receiving the substrate 106, preventing the substrate 106 from falling directly into the furnace body.
[0051] In an optional solution of this embodiment, at least one end of the connecting rod 117 is provided with an oval connecting hole 118 to correspond to the first supporting rod 107 and / or the second supporting rod 109 .
[0052] In this embodiment, since one side edge of the substrate 106 is supported by multiple first support rods 107, if the inclination angles of the multiple first support rods 107 are different, it is easy to cause some of the first support rods 107 to be unable to support the substrate 106. The same is true for the multiple second support rods 109 arranged on the other side edge of the substrate 106. The above problems will cause the stability of the support for the substrate 106 to decrease, and the substrate 106 cannot be guaranteed to be level. The present application is provided with an oval connecting hole 118 at least at one end of the connecting rod 117. When the first support rod 107 and the second support rod 109 are connected to the corresponding connecting hole 118, the connection position of the two with the connecting rod 117 can be adjusted, and then the inclination angle of the first support rod 107 and the second support rod 109 can be adjusted to make the inclination of the multiple first support rods 107 consistent and the inclination of the multiple second support rods 109 consistent.
[0053] Embodiment 3
[0054] The conveying device in the third embodiment is an improvement on the above embodiment. Different from the above embodiment in which the first bearing assembly and the second bearing assembly are arranged in parallel and spaced apart, the first bearing assembly and the second bearing assembly in the third embodiment are arranged relatively inclined. Specifically, the conveying device can be as follows: Figure 5 In the direction from the upper part to the lower part of the bearing assembly shown, the first bearing assembly and the second bearing assembly are close to each other, that is, the first bearing assembly and the second bearing assembly are relatively inclined inward, and the surface of the first bearing assembly forms an inclined bearing surface, and multiple first support assemblies are overlapped on the bearing surface of the first bearing assembly, and multiple second support assemblies are overlapped on the bearing surface of the second bearing assembly, so that the first bearing assembly and the second bearing assembly drive the multiple first support assemblies and the multiple second support assemblies forward. The surfaces of the multiple first support assemblies jointly form a first inclined surface (the inclination angle of the first inclined surface is consistent with the inclination angle of the above-mentioned bearing surface, so that the multiple first support assemblies are stably mounted on the first bearing assembly), and the surfaces of the multiple second support assemblies jointly form a second inclined surface (the inclination angle of the second inclined surface is consistent with the inclination angle of the above-mentioned bearing surface, so that the multiple second support assemblies are stably mounted on the second bearing assembly), and the first inclined surface and the second inclined surface jointly support the substrate.
[0055] In this embodiment, the first bearing assembly and the second bearing assembly can be driven by a common driving end or by different driving ends, as long as the two supporting assemblies are driven synchronously along the conveying direction.
[0056] Compared to the manner in which the first supporting component and the second supporting component are arranged in parallel and the ends of the supporting components are connected to the corresponding supporting components, the supporting components of this embodiment are arranged relatively inclined, and the supporting components can be mounted on the surface of the supporting components accordingly. The supporting components provided by the supporting components are more stably supported, thereby making the support for the substrate more stable.
[0057] In addition, based on the relative tilting arrangement of the bearing assembly, an anti-drop assembly may also be arranged between the first supporting assembly and the second supporting assembly.
[0058] On the basis of the relative tilting arrangement of the bearing components, the first support rod 107 can also be connected to the first bearing component by using the first lap plate 111, and the second support rod 109 can also be connected to the second bearing component 102 by using the second lap plate 113. The difference from the above embodiment is that in this embodiment, the angle between the first support rod 107 and the first lap plate 111 is 180 degrees, and the angle between the second support rod 109 and the second lap plate 113 is 180 degrees.
