When the wet film substrate is conveyed to the feeding position before being conveyed to the substrate conveying mechanism, the heat curing unit or the light curing unit positioned at the feeding position of the substrate conveying mechanism pre-cures the wet film positioned on the two side edges of the wet film substrate, so that the pre-cured wet film on the two side edges of the wet film substrate is not easy to damage in the conveying process of the driving roller group and in the conveying process of the driving roller group in a conventional mode, and the implementation of the subsequent process of the substrate is not influenced; when the wet film substrate is conveyed on the driving roller group, the heat curing units pre-cure the wet film at the two side edges of the wet film substrate when passing through the heat curing units on the conveying path, so that after the contact position of the wet film at the lower surface edge of the wet film substrate with the driving roller is changed, the original contact position of the wet film is softened by the heat curing units and is partially repaired, and when the pre-cured wet film is contacted with the driving roller again, the mobility of the wet film is reduced, and therefore, the wet film is not easy to damage.

In some possible implementations, the light curing unit includes: a first light source located at the upper region of both sides of the substrate transfer mechanism for irradiating both side surfaces and both upper edges of the wet film substrate to form an irradiation region; and the second light source is positioned in the area below two sides of the substrate conveying mechanism and used for irradiating two side surfaces and two lower edges of the wet film substrate to form an irradiation area.

For far infrared light source irradiation wet film, it is heat curing, wet film absorbs heat and solvent removal time is needed, therefore, only the wet film at two side edges is irradiated, other areas of the wet film substrate are not irradiated, time can be saved, and conveying efficiency can be improved.

In both cases, the support bar and the wet film substrate travel with the conveyor belt without relative displacement between the wet film substrate and the support bar on the conveyor belt. When the wet film substrate is conveyed to the feeding position before being conveyed to the conveyor belt, the heat curing unit or the light curing unit at the feeding position pre-cures the wet film on the two side edges of the wet film substrate, so that the pre-cured wet film on the two side edges of the wet film substrate is not easy to damage in the conveying process of the conveyor belt and in the carrying process of the wet film substrate in a conventional mode, and the implementation of the subsequent process of the wet film substrate 3 is not affected.

When the wet film substrate is transferred onto the second conveyor belt by the first conveyor belt, the supporting position of the supporting rod on the second conveyor belt for supporting the wet film substrate may be different from the supporting position of the supporting rod on the first conveyor belt for supporting the wet film substrate, and therefore, when the wet film substrate contacts with the supporting rod on the second conveyor belt, the wet film is not easy to damage, and when the wet film substrate passes through the pre-curing unit corresponding to the second conveyor belt, the position of the wet film substrate contacted with the supporting rod on the first conveyor belt is softened, and the original damage can be repaired to a certain extent, so that the damage of the wet film is reduced.

In some possible implementations, the distance between the two points furthest apart in the cross section of the support bar is between 0.5mm and 5mm. By using the support rod with smaller cross section, the contact area between the support rod and the wet film can be further reduced, and the damage of the wet film is reduced.

In the process of manufacturing the solar cell, photoresist is required to be coated on a cell substrate to form a wet film substrate, the wet film substrate is conveyed to curing equipment through a conveying mechanism to be cured, then the photoresist is subjected to exposure patterning treatment to be used as a mask, and then an electrode is manufactured on the cell substrate by using the mask.

For the battery substrate with the upper surface, the lower surface and the side surfaces coated with photoresist, all the surfaces of the battery substrate are in a wet film wrapping state, the wet film substrate needs to be transmitted to the next process through a conveying mechanism, but the conveying mechanism can be in contact with the wet film substrate, so that the wet film is damaged, and the manufacturing of the subsequent electrode is affected.

As shown in fig. 1, in order to reduce damage to the wet film, transfer wheels 02 with inclined rotation axes are generally disposed on two sides of the wet film substrate 01, and the transfer wheels 02 on two sides are respectively supported on two side edges of the lower surface of the wet film substrate 01 in a rolling manner, so that the position where the lower surface of the wet film substrate 01 is connected with the side surface is used as a supporting point, the transfer wheels 02 rotate to drive the wet film substrate 01 to move, but damage to the wet film at the position where the lower surface of the wet film substrate 01 is connected with the side surface can occur, for example, when an electrode is manufactured by an electroplating process, an electrode is formed on an unnecessary place on a battery substrate, and the battery performance is reduced.

In view of this, as shown in fig. 2, 4 and 5, an embodiment of the present utility model provides a wet film substrate conveying apparatus including a substrate conveying mechanism and a pre-curing unit 2; wherein the substrate conveying mechanism is used for supporting two side edges of the lower surface of the wet film substrate 3 and conveying the wet film substrate 3; the pre-curing unit 2 includes a heat curing unit and/or a light curing unit; wherein the heat curing unit is positioned on a conveying path of the substrate conveying mechanism or at a feeding position of the substrate conveying mechanism, and is used for pre-curing the wet film on at least two side edges of the wet film substrate 3 which passes through the heat curing unit and is contacted with the substrate conveying mechanism; the photo-curing unit is located at a loading position of the substrate transfer mechanism and is used for pre-curing the wet film on the two side edges of the wet film substrate 3, which are contacted with the substrate transfer mechanism, passing through the photo-curing unit before the wet film substrate 3 is transferred to the substrate transfer mechanism and when the wet film substrate 3 is transferred to the loading position.

When the wet film substrate conveying device works, the substrate conveying mechanism supports two side edges of the lower surface of the wet film substrate 3 and conveys the wet film substrate 3, when the wet film substrate 3 is conveyed to the front of the substrate conveying mechanism and is conveyed to the feeding position, the heat curing unit or the light curing unit positioned at the feeding position of the substrate conveying mechanism pre-cures the wet film positioned on the two side edges of the wet film substrate 3, so that the pre-cured wet film on the two side edges of the wet film substrate 3 is not easy to damage in the conveying process of the substrate conveying mechanism and in the conveying process of the wet film substrate in a conventional mode, and the implementation of the subsequent process of the substrate is not influenced; for example, when the wet film substrate 3 is a battery piece with both sides and sides coated with photoresist, after the wet film formed by the photoresist on the battery piece is pre-cured, damage is not easy to occur in the handling process, the position (such as a non-electrode manufacturing area) where the battery piece is not exposed, and electrode materials are not deposited in the non-electrode manufacturing area, so that the increase of resistance is avoided, and the battery performance is ensured. When the wet film substrate 3 passes through the heat curing unit located on the conveying path of the substrate conveying mechanism in the process of conveying the wet film substrate 3 on the substrate conveying mechanism, the heat curing unit pre-cures the wet film on at least two side edges of the wet film substrate 3, so that after the contact position of the wet film on the lower surface edge of the wet film substrate 3 changes, the original contact position of the wet film is softened by the heat curing unit and is partially repaired, and when the pre-cured wet film contacts the substrate conveying mechanism again, the wet film is not easy to damage due to the fact that the mobility of the wet film is reduced.

It should be noted that, the loading position refers to a position located before the substrate conveying mechanism along the conveying direction and a position closer to the starting end on the conveying path of the substrate conveying mechanism, so that before the wet film substrate 3 is conveyed to the substrate conveying mechanism and when conveyed thereon, the wet film can be pre-cured earlier, which is more beneficial to reducing damage of the wet film contacting the substrate conveying mechanism in the subsequent conveying process. Of course, the pre-curing unit 2 may be disposed at other positions on the conveying path of the substrate conveying mechanism, so long as the pre-curing can be performed, damage to the wet film can be reduced in the subsequent conveying process.

As shown in fig. 2 and 4, in some embodiments, the substrate conveying mechanism includes two sets of driving roller groups, which are respectively located at two sides of the wet film substrate 3 and are respectively used for supporting two sides of the wet film substrate 3, each set of driving roller groups includes a plurality of driving rollers 1 sequentially arranged along a conveying direction of the wet film substrate 3, and a rotation axis of the driving rollers 1 is obliquely arranged from bottom to top in a direction away from the wet film substrate 3, so that the driving rollers 1 roll and support edges of a lower surface of the wet film substrate 3. Wherein, a plurality of driving rollers 1 can share a power source, for example, a motor is in driving connection with one of the driving rollers 1, and the driving rollers 1 are in driving connection with the other driving rollers 1 through a chain, a gear or a belt; or each driving roller 1 is driven by a corresponding power source, namely, each driving roller 1 is independently connected with a motor, so long as synchronous rotation of each driving roller 1 is ensured.

When the substrate conveying mechanism works, two sides of a wet film substrate 3 are respectively placed on driving rollers 1 which are obliquely arranged in two groups of driving roller groups, the driving rollers 1 roll and support the edge of the lower surface of the wet film substrate 3, the driving rollers 1 drive the wet film substrate 3 to advance on the next driving roller 1 through rotation of the driving rollers 1, and in the advancing process of the wet film substrate 3, the contact positions of the edge of the lower surface of the wet film substrate 3 and different driving rollers 1 are continuously changed and kept in rolling contact. When the wet film substrate 3 is conveyed to the feeding position of the driving roller group before being conveyed to the driving roller group, the heat curing unit or the light curing unit at the feeding position pre-cures the wet film on the two side edges of the wet film substrate 3, so that the pre-cured wet film on the two side edges of the wet film substrate 3 is not easy to damage in the conveying process of the driving roller group and in the conveying process of the driving roller group in a conventional mode, and the implementation of the subsequent process of the substrate is not influenced. When the wet film substrate 3 passes through the thermosetting unit located on the conveying path in the process of conveying the wet film substrate 3 on the driving roller group, the thermosetting unit precurs the wet film at the two side edges of the wet film substrate 3, after the contact position of the wet film at the lower surface edge of the wet film substrate 3 with the driving roller 1 is changed, the original contact position of the wet film is softened by the thermosetting unit and is partially repaired, and when the precured wet film is contacted with other driving rollers 1, the fluidity of the precured wet film is reduced after the precuring, so that the contact damage of the wet film is not easy to happen. Thereby reducing damage to the wet film during the conveyance of the wet film substrate 3.

As shown in fig. 2 and 3, in the present embodiment, the light curing unit includes a first light source 21 and a second light source 24; wherein the first light sources 21 are located in the upper regions of the two sides of the substrate conveying mechanism, that is, the first light sources 21 are respectively arranged in the upper regions of the two sides of the substrate conveying mechanism and used for irradiating the two side surfaces and the two upper edges of the wet film substrate 3 to form irradiation regions; the second light sources 24 are located at both side lower regions of the substrate transfer mechanism, i.e., the second light sources 24 are respectively disposed at both side lower regions of the substrate transfer mechanism for irradiating both side surfaces and both side lower edges of the wet film substrate 3 to form irradiation regions.

In operation, when the wet film substrate 3 is transported on the substrate transport mechanism, the first light source 21 irradiates both side surfaces and both side upper edges of the wet film substrate 3 when passing through the positions corresponding to the first light source 21 and the second light source 24, and when the first light source 21 is a UV light source, the area irradiated by the UV light source forms an irradiation area. Meanwhile, the second light source 24 irradiates both side surfaces and both side lower edges of the wet film substrate 3, and when the second light source 24 is a UV light source, an irradiation region is formed by a region irradiated with the UV light source. By irradiation of the first light source 21 and the second light source 24, at least the upper and lower surfaces of the edges of the two sides of the wet film substrate 3 and the wet film on the sides are pre-cured under the irradiation, the wet film is cured by removing the solvent and performing the crosslinking reaction under the irradiation of the UV light source, and at this time, the wet film is irreversible after curing. If the first light source 21 and the second light source 24 are far infrared light sources, the wet film of the irradiated area is solvent-removed, thermally cured, and is not completely cured, and the wet film still has fluidity.

Of course, when the first light source 21 and the second light source 24 are far infrared light sources, the rest of the positions of the wet film substrate 3 may be irradiated at the same time, so that the wet film on the rest of the positions of the upper surface and the lower surface of the wet film substrate 3 may be pre-cured, and the irradiation areas of the first light source 21 and the second light source 24 may be selected according to the transmission requirement and the subsequent process requirement of the wet film substrate 3, which is not limited to the illustrated region of the present embodiment.

Further, as shown in fig. 2 and 3, in the present embodiment, the light curing unit further includes an upper light barrier 22 and a lower light barrier 23; the upper light barrier 22 is arranged between the two groups of driving roller groups and is positioned above the wet film substrate 3 and used for shielding the upper surface of the wet film substrate 3, the first light source 21 is positioned in an upper area outside the edges of the two sides of the upper light barrier 22, the light rays of the first light source 21 form irradiation areas on the side surfaces of the two sides and the upper edges of the two sides of the wet film substrate 3 through shielding of the upper light barrier 22, and the upper light barrier 22 has a shielding effect on the light rays of the first light source 21; the lower light barrier 23 is arranged between the two sets of driving roller sets and is positioned below the wet film substrate 3 and used for shielding the lower surface of the wet film substrate 3, the second light source 24 is positioned in a lower area outside the edges of the two sides of the lower light barrier 23, the light rays of the second light source 24 form irradiation areas on the side surfaces of the two sides and the lower edges of the two sides of the wet film substrate 3 through shielding of the lower light barrier 23, and the lower light barrier 23 has a shielding effect on the light rays of the second light source 24.

When the UV light source is used, as shown in fig. 3, the irradiation region includes an edge burst region and a shadow region, which are connected, the edge burst region is formed by direct light of the first light source 21 and the second light source 24 on the wet film substrate 3, and the shadow region is formed by diffraction of light of the first light source 21 and the second light source 24 on the wet film substrate 3; the distance between the boundary of the irradiation region on the wet film substrate 3 and the edge line of the corresponding side of the wet film substrate 3 is 500 μm to 800 μm, i.e., the width of the irradiation region on the upper surface or the lower surface; wherein the distance between the boundary line where the shadow region meets the edge burst region and the corresponding side edge line of the wet film substrate 3 is 250 μm to 400 μm, i.e., the width of the edge burst region on the upper surface or the lower surface. Within the distance range, the pre-cured wet film can meet the requirements in the conveying process, and the pre-curing effect of the wet film is good.

Under the condition of adopting the technical scheme, the upper surface of the wet film substrate 3 is shielded by the upper light barrier 22, so that the light of the first light source 21 can only irradiate on the side surfaces and the upper edges of the two sides of the wet film substrate 3, and other areas of the upper surface of the wet film substrate 3 are not irradiated by the light; the lower surface of the wet film substrate 3 is shielded by the lower light barrier 23, so that the light of the second light source 24 can only irradiate on the two side surfaces and the two side lower edges of the wet film substrate 3, and other areas of the lower surface of the wet film substrate 3 are not irradiated by the light, so that only the two side surfaces and the two side edges of the wet film substrate 3 are finally irradiated for photocuring, the requirement of reducing damage to the wet film on the two side edges of the wet film substrate 3 in the conveying process can be met, and the other positions of the wet film substrate cannot be photocured. For far infrared light source irradiation wet film, it is heat curing, wet film absorbs heat and solvent removal time is needed, therefore, only the wet film at two side edges is irradiated, other areas of the wet film substrate 3 are not irradiated, the wet film curing time can be saved, and the conveying efficiency can be improved.

As shown in fig. 2 and 3, in the present embodiment, in the case where the pre-curing unit 2 has the upper light barrier 22 and the lower light barrier 23, the upper light barrier 22 is disposed between the two sets of driving roller groups so as to be moved close to and away from the upper surface of the wet film substrate 3; and/or the lower light barrier 23 is provided between the two sets of driving rollers so as to be moved closer to and farther from the lower surface of the wet film substrate 3. That is, the upper light barrier 22 may move up and down with respect to the upper surface of the wet film substrate 3, and the lower light barrier 23 may move up and down with respect to the lower surface of the wet film substrate 3.

So arranged, the shielding range of the upper light barrier 22 to the first light source 21 can be adjusted by adjusting the distance of the upper light barrier 22 relative to the upper surface of the wet film substrate 3, so as to adjust the size of an irradiation area formed on the wet film substrate 3 by the first light source 21; and/or, adjusting the shielding range of the lower light barrier 23 to the second light source 24 by adjusting the distance of the lower light barrier 23 relative to the lower surface of the wet film substrate 3, so as to adjust the size of the irradiation area formed on the wet film substrate 3 by the second light source 24. Wherein the smaller the distance between the upper and lower light-blocking plates 22 and 23 and the wet film substrate 3, the larger the shielding range, the smaller the irradiation area formed on the wet film substrate 3.

Further, in the present embodiment, as shown in fig. 2 and 3, the first light sources 21 are fixedly disposed at both side edges of the upper light barrier 22; and/or the second light sources 24 are fixedly disposed at both side edges of the lower barrier 23.

When the distance of the upper light barrier 22 with respect to the wet film substrate 3 is adjusted, the first light source 21 moves together with the upper light barrier 22, and since both the upper light barrier 22 and the first light source 21 move with respect to the upper surface of the wet film substrate 3, the range of the irradiation region formed by the light of the first light source 21 at the upper surface of the wet film substrate 3 changes. Specifically, when the upper light barrier 22 and the first light source 21 are moved upward away from the upper surface, the range of the irradiation area becomes smaller, and vice versa. Similarly, when the distance of the lower light barrier 23 with respect to the wet film substrate 3 is adjusted, the second light source 24 moves together with the lower light barrier 23, and since the lower light barrier 23 and the second light source 24 each move with respect to the lower surface of the wet film substrate 3, the range of the irradiation region formed by the light of the second light source 24 at the lower surface of the wet film substrate 3 changes. Specifically, when the lower light barrier 23 and the second light source 24 move downward away from the lower surface, the range of the irradiation area becomes smaller, and vice versa.

It can be seen that the first light source 21 is fixedly connected with the upper light barrier 22, and the second light source 24 is fixedly connected with the lower light barrier 23, so that the size adjustment of the irradiation area can be realized, the arrangement structures of the first light source 21, the upper light barrier 22, the lower light barrier 23 and the second light source 24 are simplified, and the movement is more convenient. Of course, the first light source 21 and the second light source 24 may be provided independently of the upper light barrier 22 and the lower light barrier 23, and may be fixed, and only the upper light barrier 22 and the lower light barrier 23 may be moved, so that the size adjustment of the irradiation area may be achieved.

In some embodiments, the first light source 21 is a UV light source or a far infrared light source and the second light source 24 is a UV light source or a far infrared light source. And (3) carrying out irradiation curing on the wet film by a UV light source, and carrying out illumination heating on the wet film by a far infrared light source to remove the solvent. The wet film can be cured by irradiation, and the form of the light source is not limited to that exemplified in this embodiment.

In both cases, the support bar 5 and the wet film substrate 3 travel together with the conveyor belt 6, and no relative displacement occurs between the wet film substrate 3 and the support bar 5 on the conveyor belt 6. When the wet film substrate 3 is conveyed to the feeding position before being conveyed to the conveyor belt 6, the heat curing unit or the light curing unit at the feeding position pre-cures the wet film on the two side edges of the wet film substrate 3, so that the pre-cured wet film on the two side edges of the wet film substrate 3 is not easy to damage in the conveying process of the conveyor belt 6 and in the conveying process of the conventional manner, and the implementation of the subsequent process of the wet film substrate 3 is not affected.

Further, in the present embodiment, a heat curing unit is also provided on the conveying path of the conveyor belt 6.

When the wet film substrate 3 is transferred onto the second conveyor belt 6 by the first conveyor belt 6, the supporting position of the supporting rod 5 on the second conveyor belt 6 for supporting the wet film substrate 3 may be different from the supporting position of the supporting rod 5 on the first conveyor belt 6 for supporting the wet film substrate 3, and since the wet film of the wet film substrate 3 is pre-cured when traveling onto the second conveyor belt 6, the wet film is not easily damaged when the wet film substrate 3 contacts with the supporting rod 5 on the second conveyor belt 6, and the wet film is softened when the wet film substrate 3 passes through the pre-curing unit corresponding to the second conveyor belt 6, the original damage of the wet film can be repaired to a certain extent, thereby reducing the damage of the wet film.
