Description

Technical Field

[0001] The present invention relates to the technical field of solar cell manufacturing, and in particular to a substrate glue coating and conveying device and a control method thereof. Background Art

[0002] During the production of solar cells, photoresist needs to be coated on the cell substrate by a coating mechanism to form a wet film substrate. The wet film substrate is then transported to a curing device by a conveying mechanism to cure the photoresist. The photoresist is then exposed and patterned to serve as a mask, which is then used to make electrodes on the cell substrate.

[0003] For the battery substrate with photoresist coated on the upper and lower surfaces and sides, all surfaces of the battery substrate are in a wet film wrapped state. The wet film substrate needs to be transferred to the next process through a conveying mechanism, but the conveying mechanism will contact the wet film substrate, causing damage to the wet film and affecting the subsequent electrode production.

[0004] like Figure 1 As shown, in order to reduce the damage to the wet film, conveying wheels 02 with inclined rotation axes are usually set on both sides of the wet film substrate 01. The conveying wheels 02 on both sides are respectively supported by the two side edges of the lower surface of the wet film substrate 01 in a rolling manner, so that the edges of the lower surface of the wet film substrate 01 serve as support points. The conveying wheels rotate and drive the wet film substrate 01 to move forward. However, the wet film on the edges of the lower surface and sides of the wet film substrate 01 will also be damaged, resulting in the subsequent formation of electrodes in unnecessary places on the battery substrate, affecting the performance of the manufactured battery cells. Summary of the Invention

[0005] The object of the present invention is to provide a substrate glue coating conveying device and a control method thereof, so as to reduce the damage of the wet film during the conveying process of the wet film substrate.

[0006] In a first aspect, the present invention provides a substrate glue coating conveying device, comprising a feeding conveying mechanism, a coating mechanism and a discharging conveyor belt arranged in sequence along a conveying direction;

[0007] The feed conveyor mechanism is used to convey the substrate to be coated to the coating mechanism; wherein the lower surface of the substrate to be coated has at least one row of contact points arranged at intervals along the conveying direction of the substrate to be coated;

[0008] The coating mechanism is used to coat a wet film on the upper surface, lower surface and side surface of the substrate to be coated to form a wet film substrate;

[0009] The discharge conveyor belt is used to transport the wet film substrate. The upper surface of the discharge conveyor belt is provided with a plurality of support protrusions arranged at intervals along the conveying direction. The support protrusions are used to support corresponding contact points.

[0010] A position detection component is configured to acquire position information of the wet film substrate during the transmission of the wet film substrate from the coating mechanism to the discharge conveying belt.

[0011] A controller is in communication connection with the position detection component and configured to control operation according to the position information so that the contactable point positions on the wet film substrate correspondingly contact the support protrusions on the discharge conveying belt.

[0012] In the above technical solution, the feeding conveying mechanism conveys the substrate to be coated to the coating mechanism, the coating mechanism coats the wet film on the upper surface, lower surface and side surface of the substrate to be coated to form the wet film substrate, and the feeding conveying mechanism continues to convey the wet film substrate to the discharge conveying belt. During the transmission of the wet film substrate from the coating mechanism to the discharge conveying belt, the position detection component acquires the position information of the wet film substrate, and the controller controls operation according to the position information so that the contactable point positions on the wet film substrate correspondingly contact the support protrusions on the discharge conveying belt. Since the contactable point positions on the lower surface of the substrate to be coated are positions that can be contacted, the wet film can not be reserved on the contactable point positions, and the exposure of the contactable point positions does not affect the subsequent process. Therefore, after the wet film substrate is conveyed from the coating mechanism to the discharge conveying belt, the wet film in the area other than the contactable point positions on the wet film substrate is prevented from being damaged. When the metal electrode is subsequently manufactured, the electrode is not formed in positions where it should not be formed, so that the resistance is not increased, and the battery performance is ensured.

[0013] In some possible implementation manners, the position detection component is fixed at a position above the coating mechanism and the discharge conveying belt, and is configured to acquire image information of a side edge of the wet film substrate close to the discharge conveying belt and a support protrusion on the discharge conveying belt close to the wet film substrate during the transmission of the wet film substrate from the coating mechanism to the discharge conveying belt.

[0014] The controller is configured to determine a relative position deviation value between a contactable point position on the wet film substrate close to the discharge conveying belt and a support protrusion corresponding to supporting the contactable point position according to the image information, and control the conveying speed of the discharge conveying belt according to the relative position deviation value, so that the contactable point position correspondingly contacts the support protrusion during the transmission of the wet film substrate.

[0015] When the above technical solution is adopted, in the process of the wet film substrate being transported from the coating mechanism to the discharge conveyor, the image information of the side edge of the wet film substrate close to the discharge conveyor and the supporting protrusion on the discharge conveyor close to the wet film substrate is obtained by the position detection component. Afterwards, the controller determines the relative position deviation value between the contactable point on the wet film substrate close to the discharge conveyor and the corresponding supporting protrusion supporting the contactable point based on the image information. That is, when the distance between the side edge of the wet film substrate close to the discharge conveyor and the contactable point on the wet film substrate closest to the side edge, as well as the distance between two adjacent supporting protrusions on the discharge conveyor are known in advance, the relative position deviation value between the side edge of the wet film substrate close to the discharge conveyor and the supporting protrusion on the discharge conveyor close to the contactable point can be determined based on the image information. The image information of the supporting protrusions near the wet film substrate is used to obtain a relative position deviation value. Then, the controller controls the instantaneous conveying speed of the discharge conveyor belt according to the relative position deviation value, and adjusts the distance between the supporting protrusions on the discharge conveyor belt and the contactable points to be supported in the conveying direction, so that the contactable points on the wet film substrate closest to one side edge first contact with the supporting protrusions on the discharge conveyor belt. Then, the conveying speeds of the discharge conveyor belt and the feed conveyor mechanism are kept consistent, so that the contactable points on the wet film substrate that are successively exposed from the coating mechanism can contact with the supporting protrusions on the discharge conveyor belt in sequence, thereby avoiding the supporting protrusions on the discharge conveyor belt from contacting areas other than the contactable points on the wet film substrate, thereby avoiding damage to the wet film on the wet film substrate.

[0016] In some possible implementations, the substrate glue coating and conveying device also includes a position adjustment mechanism, the controller is communicatively connected to the position adjustment mechanism, the position adjustment mechanism is drive-connected to the discharge conveyor belt, the position adjustment mechanism is used to drive at least one end of the discharge conveyor belt close to the coating mechanism to move in a horizontal direction perpendicular to the conveying direction, and the controller is also used to control the action of the position adjustment mechanism according to the relative position deviation value.

[0017] When adopting the above technical solution, if there is a position deviation between the supporting protrusion on the discharge conveyor belt and the contactable point on the wet film substrate that is about to contact in the horizontal direction perpendicular to the conveying direction, the controller can also control the position adjustment mechanism to move at least one end of the discharge conveyor belt close to the coating mechanism in the horizontal direction perpendicular to the conveying direction, and adjust the position of the supporting protrusion on the discharge conveyor belt so that the supporting protrusion on the discharge conveyor belt contacts the contactable point on the wet film substrate.

[0018] In some possible implementations, the position adjustment mechanism is a telescopic cylinder, which is arranged on both sides of one end of the discharge conveyor belt close to the coating mechanism. The telescopic direction of the telescopic end of the telescopic cylinder is a horizontal direction perpendicular to the conveying direction, and the telescopic end of the telescopic cylinder is drive-connected to the end of the discharge conveyor belt close to the coating mechanism.

[0019] When adopting the above technical solution, the end of the discharge conveyor belt close to the coating mechanism is linearly driven by the telescopic cylinder to move in a horizontal direction perpendicular to the conveying direction, and the other end of the coating mechanism remains stationary, which is equivalent to adjusting the deflection angle of the discharge conveyor belt. It is sufficient to adjust the position of the end of the discharge conveyor belt close to the coating mechanism.

[0020] In some possible implementations, the substrate glue coating conveying device further includes at least two pairs of first support components, which are arranged sequentially along the conveying direction of the discharge conveyor belt and move independently, and the first support components are provided with lifting protrusions, which are used to support corresponding contact points, and each pair of first support components is used to lift the contact points on both sides of the wet film substrate respectively;

[0021] The position detection component is located between the coating mechanism and the discharge conveyor belt, and is used to detect the position information of the contact points of the wet film substrate conveyed from the coating mechanism;

[0022] The controller is in communication with the first supporting component. The controller is used to control at least two pairs of first supporting components to sequentially lift the contactable points on the wet film substrate that are gradually moved out of the coating mechanism based on the position information and the position of the first supporting component, and to control at least two pairs of first supporting components to lift and transfer the wet film substrate from the coating mechanism to the discharge conveyor belt, so that the supporting protrusions on the discharge conveyor belt are supported on the contactable points of the wet film substrate.

[0023] When the above technical solution is adopted, during the process of conveying the wet-film substrate from the coating mechanism to the discharge conveyor, the position detection component detects the position information of the contactable points of the wet-film substrate conveyed from the coating mechanism. Based on the position information and the position of the first support component, the controller controls the first support component to sequentially lift the contactable points on the wet-film substrate that gradually emerge from the coating mechanism. The first support component supports and contacts the contactable points via the lifting protrusions thereon. The controller controls the first support component to lift and transfer the wet-film substrate from the coating mechanism to the discharge conveyor, and causes the support protrusions on the discharge conveyor to support the contactable points of the wet-film substrate. Because the contactable points of the wet-film substrate are supported by the lifting protrusions of the first support component and lifted and transported to the discharge conveyor, damage to the wet film in areas outside the contactable points on the wet-film substrate is avoided during the process of the wet-film substrate being lifted by the first support component and during the process of the wet-film substrate being conveyed on the discharge conveyor.

[0024] In some possible implementations, the substrate glue coating and conveying device further includes a heating unit, which is disposed on a conveying path of the discharge conveyor belt and is configured to heat the wet film of the wet film substrate to remove solvent and solidify the wet film.

[0025] When the above technical solution is adopted, when the wet film substrate transported on the discharge conveyor belt passes through the heating unit, the heating unit heats the wet film on the wet film substrate to remove the solvent, solidify and pre-bake.

[0026] In some possible implementations, the substrate gluing conveying device further includes at least two pairs of second supporting components, the first supporting component, the heating unit and the second supporting component are arranged sequentially along the conveying direction, at least two pairs of second supporting components are arranged sequentially along the conveying direction, the second supporting components are provided with lifting protrusions, the lifting protrusions are used to correspond to support at contactable points, and each pair of second supporting components is respectively used to lift the contactable points on both sides of the wet film substrate; the controller is communicatively connected to the second supporting components, and the controller is also used to control at least two pairs of second supporting components to transfer the wet film substrate away from the discharge conveyor belt.

[0027] When the above technical solution is adopted, after the wet film curing and pre-baking are completed, the controller controls the second supporting component to transfer the wet film substrate away from the discharge conveyor belt, and the lifting protrusions on the second supporting component support and contact the contactable points on the wet film substrate. Therefore, the wet film will not be damaged during the transfer of the wet film substrate.

[0028] In some possible implementations, both the first and second support members are L-shaped structures, comprising a connected vertical portion and a horizontal portion, with the lifting protrusions disposed on the horizontal portion. The horizontal portion of the L-shaped structure extends beneath the wet-film substrate, supporting the wet-film substrate at accessible points via the lifting protrusions on the horizontal portion. This prevents contact between the first and second support members and other portions of the wet-film substrate, protecting the wet film from damage.

[0029] In some possible implementations, the discharge conveyor is a closed-loop conveyor that circulates in one direction, and the conveying path of the discharge conveyor sequentially passes through a receiving station, a heating station, a transfer station, and a cleaning and drying station; the first supporting component is used to transfer the wet film substrate from the coating mechanism to the receiving station, the heating unit is provided at the heating station, and the second supporting component is used to transfer the wet film substrate away from the transfer station;

[0030] The substrate gluing and conveying device also includes a cleaning and drying unit, which is arranged on the cleaning and drying station of the discharge conveyor belt and is used to clean and dry the discharge conveyor belt passing through the cleaning and drying station.

[0031] When the above technical solution is adopted, the discharge conveyor belt is a closed-loop conveyor belt that moves in a circular motion. The wet film substrate is placed on the discharge conveyor belt at the material receiving station, and then the discharge conveyor belt drives the wet film substrate to move to the heating station for heating and curing. After that, the discharge conveyor belt drives the wet film substrate to move to the transplanting station, and the wet film substrate is transferred away from the discharge conveyor belt by the second supporting component. Finally, the empty discharge conveyor belt moves to the cleaning and drying station to complete the cleaning of the discharge conveyor belt, and then returns to the material receiving station to continue conveying the wet film substrate.

[0032] In some possible implementations, the position detection component is an image sensor. The image sensor detects image information, and the controller obtains a relative position deviation value based on the image information, so that the image information is more accurate and clear.

[0033] In some possible implementations, the coating mechanism includes two sets of glue coating components, which are respectively arranged above and below the substrate to be coated, and are used to apply glue to the upper surface and lower surface of the substrate to be coated. Each set of glue coating components includes:

[0034] The glue liquid outlet device is arranged at the discharge end of the feed conveying mechanism, and the glue liquid outlet device has a glue dripping port;

[0035] The coating roller is rotatably arranged below the glue dripping port of the glue liquid outlet device, and the glue dripping port provides glue to the surface of the coating roller. The coating roller is used to contact the surface of the substrate to be coated so as to coat the glue covering the surface of the coating roller on the upper surface, lower surface and side surfaces of the substrate to be coated.

[0036] When the above solution is adopted, two sets of glue coating components are used to simultaneously coat the upper and lower surfaces of the substrate to be coated, and the coating roller is set to roll in contact with the substrate to be coated, so that the substrate can be smoothly transferred and its surface coated with glue.

[0037] In some possible implementations, the glue coating assembly further includes a glue spreading roller, which is rotatably disposed below the glue drop port and in rolling contact with the coating roller. The glue spreading roller is used to evenly cover the glue liquid on the surface of the coating roller.

[0038] When adopting the above scheme, by setting up a glue-distributing roller and bringing it into rolling contact with the coating roller, the glue liquid discharged from the glue drop port can be evenly covered on the surface of the coating roller by extrusion. The coating roller is in rolling contact with the substrate, which can achieve uniform coating on the surface of the substrate, improve the glue coating quality of the substrate, and ensure the uniformity of the glue coating thickness on the surface of the substrate.

[0039] In a second aspect, the present invention further provides a control method for a substrate glue coating conveying device, wherein the substrate glue coating conveying device comprises a feed conveying mechanism, a coating mechanism, and a discharge conveyor belt sequentially arranged along a conveying direction, and the control method comprises the following steps:

[0040] transporting the substrate to be coated to the coating mechanism by a feeding conveying mechanism; wherein the lower surface of the substrate to be coated has at least one row of contactable positions arranged at intervals along the conveying direction of the substrate to be coated;

[0041] controlling the coating mechanism to coat the wet film on the upper surface, the lower surface and the side surface of the substrate to be coated, to form a wet film substrate;

[0042] acquiring position information of the wet film substrate during the process of transferring the wet film substrate from the coating mechanism to the discharging conveying belt;

[0043] controlling the contactable positions of the wet film substrate to correspondingly contact the supporting protrusions on the discharging conveying belt during the conveying process according to the position information.

[0044] The technical effects achieved by the control method of the substrate coating and conveying device are the same as those described in the first aspect. During the process of conveying the wet film substrate from the coating mechanism to the discharging conveying belt, the position detection component acquires the position information of the wet film substrate, and the controller controls the operation according to the position information, so that the contactable positions on the wet film substrate correspondingly contact the supporting protrusions on the discharging conveying belt. Since the contactable positions arranged at intervals along the conveying direction on the lower surface of the substrate to be coated are positions that can be contacted, the wet film can not be reserved on the contactable positions, and the exposure of the contactable positions does not affect the subsequent process.

[0045] In some possible implementations, acquiring the position information of the wet film substrate includes:

[0046] acquiring image information of the side edge of the wet film substrate close to the discharging conveying belt and the supporting protrusions on the discharging conveying belt close to the wet film substrate;

[0047] controlling the contactable positions of the wet film substrate to correspondingly contact the supporting protrusions on the discharging conveying belt during the conveying process according to the position information includes:

[0048] determining a relative position deviation value between the contactable positions of the wet film substrate close to the discharging conveying belt and the supporting protrusions for supporting the contactable positions according to the image information, and controlling the conveying speed of the discharging conveying belt according to the relative position deviation value, to control the contactable positions of the wet film substrate to correspondingly contact the supporting protrusions during the conveying process.

[0049] When adopting the above technical solution, when the distance between one side edge of the wet film substrate close to the discharge conveyor belt and the contactable point on the wet film substrate closest to the side edge, as well as the distance between two adjacent supporting protrusions on the discharge conveyor belt are determined in advance, a relative position deviation value can be obtained based on the image information of the one side edge of the wet film substrate close to the discharge conveyor belt and the supporting protrusion on the discharge conveyor belt close to the wet film substrate. Thereafter, the instantaneous conveying speed of the discharge conveyor belt is controlled according to the relative position deviation value, and the distance between the supporting protrusion on the discharge conveyor belt and the contactable point to be supported in the conveying direction is adjusted, so that the contactable point on the wet film substrate closest to the one side edge first contacts the corresponding supporting protrusion on the discharge conveyor belt, thereby avoiding damage to the wet film of the wet film substrate during transportation.

[0050] In some possible implementations, controlling the contact points of the wet film substrate to contact correspondingly with the supporting protrusions on the discharge conveyor belt during the transport process based on the position information includes:

[0051] At least one end of the discharge conveyor belt close to the coating mechanism is controlled to move in a horizontal direction perpendicular to the conveying direction according to the relative position deviation value.

[0052] When adopting the above technical solution, if there is a position deviation between the supporting protrusion on the discharge conveyor belt and the contactable point on the wet film substrate that is about to be in contact in the horizontal direction perpendicular to the conveying direction, the discharge conveyor belt is controlled to move in the horizontal direction perpendicular to the conveying direction at least at one end close to the coating mechanism, and the position of the supporting protrusion on the discharge conveyor belt is adjusted so that the supporting protrusion on the discharge conveyor belt is in contact with the contactable point on the wet film substrate.

[0053] In some possible implementations, the substrate glue coating conveying device further includes at least two pairs of first support components, which are sequentially arranged along the conveying direction of the discharge conveyor belt and move independently. The first support components are provided with lifting protrusions, which are used to support corresponding contact points. Each pair of first support components is used to lift contact points on both sides of the wet film substrate respectively. Obtaining the position information of the wet film substrate includes:

[0054] Acquiring position information of contactable points of the wet film substrate conveyed from the coating mechanism;

[0055] According to the position information, the contact points of the wet film substrate during the transmission process are controlled to contact with the supporting protrusions on the discharge conveyor belt, including:

[0056] According to the position information and the position of the first supporting component, at least two pairs of first supporting components are controlled to sequentially lift the contactable points on the wet film substrate that are gradually moved out of the coating mechanism, and at least two pairs of first supporting components are controlled to lift and transfer the wet film substrate from the coating mechanism to the discharge conveyor belt, so that the supporting protrusions on the discharge conveyor belt are supported on the contactable points of the wet film substrate.

[0057] When the above technical solution is adopted, the position detection component detects the position information of the contactable points of the wet film substrate transported out from the coating mechanism. The controller controls the first supporting component to sequentially lift the contactable points on the wet film substrate that are gradually exposed from the coating mechanism based on the position information and the position of the first supporting component. Since the contactable points of the wet film substrate are supported by the lifting protrusions of the first supporting component and lifted and transported to the discharge conveyor belt, damage to the wet film in areas other than the contactable points on the wet film substrate is avoided.

[0058] In some possible implementations, the substrate glue coating conveying device further includes at least two pairs of second supporting components, the first supporting components and the second supporting components are sequentially arranged along the conveying direction, and the at least two pairs of second supporting components are sequentially arranged along the conveying direction, the second supporting components are provided with lifting protrusions, and the lifting protrusions are used to support corresponding contact points, and each pair of second supporting components is respectively used to lift the contact points on both sides of the wet film substrate; after the support protrusions on the discharge conveyor belt support the contact points of the wet film substrate, the control method further includes the steps of:

[0059] At least two pairs of second supporting components are controlled to transfer the wet film substrate away from the discharge conveyor belt.

[0060] When the above technical solution is adopted, the second supporting component is controlled to transfer the wet film substrate away from the discharge conveyor belt, and the lifting protrusions on the second supporting component are supported and contacted with the contactable points on the wet film substrate. Therefore, the wet film will not be damaged during the transfer of the wet film substrate.

[0061] In some possible implementations, after the support protrusions on the discharge conveyor belt support the contactable points of the wet film substrate, and before at least two pairs of second support components transfer the wet film substrate away from the discharge conveyor belt, the control method further includes the step of heating the wet film of the wet film substrate transported on the discharge conveyor belt to remove solvent and solidify it.

[0062] In some possible implementations, after controlling the at least two pairs of second supporting components to transfer the wet film substrate away from the discharge conveyor belt, the control method further includes the step of: cleaning and drying the discharge conveyor belt.

[0063] In the above technical solution, after the wet film substrate is transferred away from the discharge conveying belt, the empty discharge conveying belt moves to the cleaning and drying station to complete cleaning of the discharge conveying belt, the conveying of the wet film substrate can be continuously recycled, and pollution of the wet film by residual substances on the discharge conveying belt is avoided.

[0079] In the process of manufacturing a solar cell, a photoresist is coated on a cell substrate by a coating mechanism to form a wet film substrate, the wet film substrate is transported to a curing device by a conveying mechanism for photoresist curing, and then the photoresist is exposed and patterned to make the photoresist as a mask, and then the mask is used to manufacture electrodes on the cell substrate.

[0080] For the upper and lower surfaces and the side surface are coated with photoresist on the battery substrate, all surfaces of the battery substrate are wrapped with wet film, and the wet film substrate needs to be transmitted to the next process by a conveying mechanism. However, the conveying mechanism will contact the wet film substrate, causing damage to the wet film and affecting the subsequent electrode manufacturing.

[0081] As shown in the prior art, Figure 1 , in order to reduce the damage of the wet film, a conveying wheel 02 with an inclined rotation axis is usually arranged on both sides of the wet film substrate 01. The conveying wheels 02 on both sides are rolled and supported on the two side edges of the lower surface of the wet film substrate 01, so that the edges of the lower surface of the wet film substrate 01 are the supporting points. The conveying wheels rotate to drive the wet film substrate 01 to move forward. However, the wet film on the edges of the lower surface of the wet film substrate 01 will also be damaged, causing the formation of electrodes in places where they are not needed on the battery substrate, resulting in increased resistance and affecting the performance of the battery.

[0082] In view of this, as shown in the prior art, Figure 2 , Figure 3 and Figure 5 , the embodiment of the present application provides a substrate coating conveying device, which comprises a position detection component 5, a controller (not shown in the figure), a feeding conveying mechanism 1, a coating mechanism 2 and an output conveying belt 3. The feeding conveying mechanism 1, the coating mechanism 2 and the output conveying belt 3 are arranged in sequence along the conveying direction. The feeding conveying mechanism 1 is used to convey the substrate to be coated to the coating mechanism 2. As shown in the prior art, Figure 2 , the lower surface of the substrate to be coated has at least one row of contactable point positions 41 arranged at intervals along the conveying direction of the substrate to be coated. The contactable point position 41 refers to a point position that can not retain wet film, allows contact and will not affect the subsequent process. For example, the contactable point position 41 is the position used to clamp the battery piece when the battery piece is electroplated with an electrode. The coating mechanism 2 is used to coat wet film on the upper surface, the lower surface and the side surface of the substrate to be coated, forming a wet film substrate 4. Correspondingly, the wet film substrate 4 also has the same position of the contactable point position 41. The output conveying belt 3 is used to convey the wet film substrate 4. The upper surface of the output conveying belt 3 is provided with a plurality of supporting protrusions 31 arranged at intervals along the conveying direction. The supporting protrusions 31 protrude from the conveying surface of the output conveying belt 3. The supporting protrusions 31 are used to correspondingly support the contactable point positions 41. The end surface area of the supporting protrusions 31 is less than or equal to the area of the contactable point positions 41, so that the supporting protrusions 31 are supported within or coincide with the boundary of the contactable point positions 41, and will not exceed the boundary of the contactable point positions 41. The position detection component 5 is used to obtain the position information of the wet film substrate 4 during the transmission of the wet film substrate 4 from the coating mechanism 2 to the output conveying belt 3. The controller is in communication connection with the position detection component 5, and is used to perform control operation according to the position information, so that the contactable point positions 41 on the wet film substrate 4 correspondingly contact the supporting protrusions 31 on the output conveying belt 3.

[0083] When the substrate glue coating and conveying device is working, the feeding conveying mechanism 1 conveys the substrate to be coated to the coating mechanism 2, and the coating mechanism 2 coats a wet film on the upper surface, lower surface and side surface of the substrate to be coated to form a wet film substrate 4. The feeding conveying mechanism 1 continues to convey the wet film substrate 4 to the discharge conveyor belt 3. In the process of the wet film substrate 4 being transferred from the coating mechanism 2 to the discharge conveyor belt 3, the position detection component 5 obtains the position information of the wet film substrate 4. The controller performs control operations according to the position information, so that the contactable point 41 on the wet film substrate 4 contacts with the support protrusion 31 on the discharge conveyor belt 3. The discharge conveyor belt 3 supports and conveys the wet film substrate 4 through the support protrusion 31 thereon.

[0084] Since the contact points 41 on the lower surface of the substrate to be coated that are arranged at intervals along the conveying direction are contactable positions, the wet film does not need to be retained on the contact points 41, and the exposure of the contact points 41 does not affect the subsequent process. Therefore, after the wet film substrate 4 is conveyed from the coating mechanism 2 to the discharge conveyor belt 3, damage to the wet film in areas outside the contact points 41 on the wet film substrate 4 is avoided. When the metal electrode is subsequently manufactured, the electrode will not be formed at a position where the electrode should not be formed. Therefore, the resistance will not increase, and the battery performance is guaranteed.

[0085] like Figure 3 and Figure 4 As shown, this embodiment provides a specific substrate glue coating and conveying device, in which the position detection component 5 of the substrate glue coating and conveying device is fixed at an upper position between the coating mechanism 2 and the discharge conveyor belt 3. The position detection component 5 is used to obtain image information of the side edge of the wet film substrate 4 close to the discharge conveyor belt 3 and the support protrusion 31 on the discharge conveyor belt 3 close to the wet film substrate 4 during the process of the wet film substrate 4 being transported from the coating mechanism 2 to the discharge conveyor belt 3. The image field obtained by the position detection component 5 is as follows: Figure 4 The area in the dotted circle in Figure 3 and Figure 4 In the orientation shown, the image information between the right edge of the wet film substrate 4 and the supporting protrusion 31 at the leftmost end of the upper conveying surface of the discharge conveyor belt 3 is used to determine the distance between the right edge of the wet film substrate 4 and the supporting protrusion 31 at the leftmost end of the upper conveying surface.

[0086] The controller is used to determine the relative position deviation between the contactable point 41 on the wet film substrate 4 close to the discharge conveyor belt 3 and the supporting protrusion 31 for correspondingly supporting the contactable point 41 according to the image information, that is, Figure 3 and Figure 4In the orientation shown, the relative position deviation between the contactable point 41 closest to the right edge of the wet-film substrate 4 and the supporting protrusion 31 on the discharge conveyor 3 that is about to contact and support the contactable point 41 is determined based on the image information; the controller controls the conveying speed of the discharge conveyor 3 based on the relative position deviation so that the contactable point 41 and the supporting protrusion 31 correspondingly contact each other during the conveyance of the wet-film substrate 4.

[0087] Since the wet film substrate 4 is close to one side edge of the discharge conveyor belt 3 ( Figure 3 the right edge) to the contactable point 41 ( Figure 3 The distance between the rightmost contact point 41 on the wet film substrate 4 is known, and the distance between two adjacent support protrusions 31 on the discharge conveyor belt 3 is also known. Therefore, the relative position deviation value can be obtained based on the image information obtained by the position detection component 5 and the above-mentioned known distance. After that, the controller controls the instantaneous conveying speed of the discharge conveyor belt 3 according to the relative position deviation value, and adjusts the distance between the support protrusion 31 on the discharge conveyor belt 3 and the contact point 41 to be supported in the conveying direction, that is, Figure 4 For example, when the support protrusion 31 on the discharge conveyor belt 3 that is about to contact the contactable point 41 on the wet-film substrate 4 moves to the right of the contactable point 41, the moving speed of the discharge conveyor belt 3 is instantaneously reduced. Conversely, the moving speed of the discharge conveyor belt 3 is instantaneously increased, so that the contactable point 41 on the wet-film substrate 4 closest to the right edge first contacts the support protrusion 31 on the discharge conveyor belt 3. Thereafter, the conveying speeds of the discharge conveyor belt 3 and the infeed conveyor mechanism 1 are kept consistent, so that the contactable points 41 on the wet-film substrate 4 that are successively exposed from the coating mechanism 2 contact the support protrusion 31 on the discharge conveyor belt 3 in sequence, thereby preventing the support protrusion 31 on the discharge conveyor belt 3 from contacting areas of the wet-film substrate 4 other than the contactable point 41, thereby preventing damage to the wet film on the wet-film substrate 4.

[0088] like Figure 4 As shown, further, in this embodiment, the substrate glue coating conveying device also includes a position adjustment mechanism (not shown in the figure), the controller is communicated with the position adjustment mechanism, the position adjustment mechanism is driven and connected to the discharge conveyor belt 3, and the position adjustment mechanism is used to drive at least one end of the discharge conveyor belt 3 close to the coating mechanism 2 to move in a horizontal direction perpendicular to the conveying direction, that is, along Figure 4 The position of the discharge conveyor belt 3 is adjusted in the y direction. The position adjustment mechanism can only adjust the position of one end of the discharge conveyor belt 3 close to the coating mechanism 2, or can adjust the positions of both ends of the discharge conveyor belt 3 at the same time. The controller is also used to control the action of the position adjustment mechanism according to the relative position deviation value.

[0089] When adopting the above technical solution, if there is a position deviation between the supporting protrusion 31 on the discharge conveyor belt 3 and the contactable point 41 on the wet film substrate 4 that is about to contact in the horizontal direction perpendicular to the conveying direction (in the y direction in Figure 4), the controller can also control the action of the position adjustment mechanism, and the position adjustment mechanism drives at least one end of the discharge conveyor belt 3 close to the coating mechanism 2 to move in the horizontal direction perpendicular to the conveying direction, and adjusts the position of the supporting protrusion 31 on the discharge conveyor belt 3 so that the supporting protrusion 31 on the discharge conveyor belt 3 contacts the contactable point 41 on the wet film substrate 4.

[0090] Exemplarily, the position adjustment mechanism can be a telescopic cylinder, which is arranged on both sides of one end of the discharge conveyor belt 3 close to the coating mechanism 2. The telescopic direction of the telescopic end of the telescopic cylinder is a horizontal direction perpendicular to the conveying direction. The telescopic end of the telescopic cylinder is driven and connected to the end of the discharge conveyor belt 3 close to the coating mechanism 2.

[0091] When adjusting in the y direction, the end of the discharge conveyor belt 3 close to the coating mechanism 2 is linearly driven by the telescopic cylinders on both sides to move in a horizontal direction perpendicular to the conveying direction, and the other end of the coating mechanism 2 remains stationary, which is equivalent to adjusting the deflection angle of the discharge conveyor belt 3. It is sufficient as long as the position of the end of the discharge conveyor belt 3 close to the coating mechanism 2 can be adjusted.

[0092] Of course, telescopic cylinders can also be installed on both ends of the discharge conveyor belt 3, with the telescopic ends of the telescopic cylinders simultaneously driving both ends of the discharge conveyor belt 3 to achieve overall translation or deflection of the discharge conveyor belt in the y direction. Besides using telescopic cylinders, the position adjustment mechanism can also be a movable support platform installed below the discharge conveyor belt 3. The support platform's movement in the y direction drives the entire discharge conveyor belt 3 in the y direction. As long as the discharge conveyor belt 3 can be adjusted in the y direction, the mechanism is not limited to the embodiments listed in this embodiment.

[0093] like Figure 2 、 Figure 5-10 As shown, this embodiment provides another specific substrate glue coating conveying device, which includes a feed conveying mechanism 1, a coating mechanism 2, a discharge conveyor belt 3, a controller and a position detection component 5, and further includes at least two pairs of first support components 6, such as Figure 10As shown, the two first supporting members 6 located on both sides of the wet film substrate 4 form a pair, and at least two pairs of first supporting members 6 They are arranged in sequence along the conveying direction of the discharge conveyor 3 and move independently. The first supporting components 6 are provided with lifting protrusions 63, which are used to support the contactable points 41 accordingly. Each pair of first supporting components 6 is used to lift the contactable points 41 on both sides of the wet film substrate 4 respectively; wherein, the position detection component 5 is located between the coating mechanism 2 and the discharge conveyor 3, and is used to detect the position information of the contactable points 41 of the wet film substrate 4 conveyed from the coating mechanism 2; the controller is communicated with the first supporting components 6, and the controller is used to control at least two pairs of first supporting components 6 to sequentially lift the contactable points 41 on the wet film substrate 4 that are gradually moved out of the coating mechanism 2 according to the position information and the position of the first supporting components 6, and control at least two pairs of first supporting components 6 to lift and transfer the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor 3, and make the supporting protrusions 31 on the discharge conveyor 3 support the contactable points 41 of the wet film substrate 4.

[0094] When the substrate glue coating and conveying device is working, during the process of conveying the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3, the position detection component 5 detects the position information of the contactable point 41 of the wet film substrate 4 conveyed from the coating mechanism 2, that is, determines the current position of the contactable point 41, and the controller controls the first supporting component 6 to move and sequentially lift the contactable points 41 on the wet film substrate 4 that are gradually exposed from the coating mechanism 2 according to the position information and the position of the first supporting component 6. The first supporting component 6 supports and contacts the contactable points 41 through the lifting protrusions 63 thereon. The controller controls the first supporting component 6 to lift and transfer the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3, and makes the supporting protrusions 31 on the discharge conveyor belt 3 support the contactable points 41 of the wet film substrate 4. Since the contactable points 41 of the wet film substrate 4 are supported by the lifting protrusions 63 of the first supporting member 6 and lifted and transported to the discharge conveyor 3, damage to the wet film in areas other than the contactable points 41 of the wet film substrate 4 is avoided during the process of lifting the wet film substrate 4 by the first supporting member 6 and during the process of conveying the wet film substrate 4 on the discharge conveyor 3.

[0095] For example, Figure 2 As shown, the contact points 41 on the wet film substrate 4 can be arranged in two rows, three rows, etc. Taking two rows as an example, the two rows of contact points 41 correspond to each other, and the number of contact points 41 in each row can be two, three, four, five, six or more. For example, five pairs of contact points 41, Aa, Bb, Cc, Dd, and Ee, can be formed. When the wet film substrate 4 starts to be transferred from the coating mechanism 2 to the discharge conveyor 3, as shown in FIG. Figure 6As shown, the position detection component 5 detects that the wet film substrate 4 has reached the detection position from the first pair of contactable points Aa exposed on the coating mechanism 2, and obtains the position information of the first pair of contactable points Aa as the origin position. At this time, the discharge end of the coating mechanism 2 continues to transport the wet film substrate 4 at a uniform speed, as shown in FIG. Figure 7 As shown, the controller controls the first pair of first support members 6 to move to the position where the first pair of contactable points Aa reach within the preset movement time based on the position information and the current position of the first pair of first support members 6, and based on the speed of the wet film substrate 4 and the preset movement time. Thereafter, the controller controls the first pair of first support members 6 to move horizontally synchronously with the wet film substrate 4 until the first pair of first support members 6 are hoisted on the first pair of contactable points Aa. Figure 8 As shown, the wet film substrate 4 continues to be transported at a constant speed, and the second pair of contact points Bb and the third pair of contact points Cc are sequentially revealed. According to the movement control method of the first pair of first support members 6, the controller controls the second pair of first support members 6 to move and hang on the third pair of contact points Cc, while the second pair of contact points Bb are not hung. Figure 9 As shown, the wet film substrate 4 continues to be transported, and the fourth pair of contact points Dd and the fifth pair of contact points Ee are sequentially revealed. According to the movement control method of the first pair of first support components 6, the controller controls the third pair of first support components 6 to move and hoist them on the fifth pair of contact points Ee, while the fourth pair of contact points Dd is not hoisted. The controller then controls the three pairs of first support components 6 to hoist a wet film substrate 4 together and transfer it to the discharge conveyor belt 3. During this process, the discharge conveyor belt 3 can be stopped. According to the position of the fixed support protrusions 31 on the discharge conveyor belt 3, the controller controls the three pairs of first support components 6 to place the second pair of contact points Bb and the fourth pair of contact points Dd on the wet film substrate 4 on the corresponding support protrusions 31 on the discharge conveyor belt 3. The remaining three pairs of contact points 41 are not supported by the support protrusions 31, as shown in FIG. Figure 5 As shown, after that, the three pairs of first supporting components 6 are released and moved away, completing the transfer of the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3.

[0096] Of course, another way for the controller to control at least two pairs of first supporting components 6 to sequentially lift the contact points 41 on the wet film substrate 4 that are gradually moved out of the coating mechanism 2 according to the position information and the position of the first supporting component 6 can be: the position detection component 5 detects that the first pair of contact points Aa of the wet film substrate 4 exposed from the coating mechanism 2 arrives at the detection position, obtains the position information of the first pair of contact points Aa, and at this time, stops conveying the wet film substrate 4, such as Figure 7As shown, the controller controls the first pair of first support members 6 to move to the first pair of contactable points Aa according to the fixed position information and the current position of the first pair of first support members 6, and hoist them on the first pair of contactable points Aa. After that, the wet film substrate 4 is continuously transported, and the first pair of first support members 6 is controlled to move horizontally synchronously with the wet film substrate 4. Figure 8 As shown, the wet film substrate 4 continues to be transported at a constant speed, and the second pair of contact points Bb and the third pair of contact points Cc are sequentially revealed. When the third pair of contact points Cc reaches the detection position of the position detection component 5, the transport of the wet film substrate 4 is stopped. According to the movement control method of the first pair of first support components 6, the controller controls the second pair of first support components 6 to move and hoist them on the third pair of contact points Cc, while the second pair of contact points Bb are not hoisted. Figure 9 As shown, the wet film substrate 4 continues to be transported, the second pair of first supporting members 6 moves horizontally synchronously with the wet film substrate 4, and the fourth pair of contact points Dd and the fifth pair of contact points Ee are sequentially revealed. According to the movement control method of the first pair of first supporting members 6, the controller controls the third pair of first supporting members 6 to move and be hoisted on the fifth pair of contact points Ee, while the fourth pair of contact points Dd is not hoisted. The controller then controls the three pairs of first support components 6 to lift a wet film substrate 4 and transfer it to the discharge conveyor 3. During this process, the three pairs of first support components 6 move horizontally synchronously with the discharge conveyor 3. The controller determines the position that the specific support protrusion 31 on the discharge conveyor 3 reaches within the movement time based on the current position of the specific support protrusion 31 on the discharge conveyor 3 and the movement speed and movement time of the discharge conveyor 3. It also controls the three pairs of first support components 6 to place the second pair of contactable points Bb and the fourth pair of contactable points Dd on the wet film substrate 4 on the corresponding support protrusions 31 on the discharge conveyor 3. The remaining three pairs of contactable points 41 are not supported by the support protrusions 31. Figure 5 As shown, after that, the three pairs of first supporting components 6 are released and moved away, completing the transfer of the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3.

[0097] Of course, the position of the first support member 6 relative to the contactable point can also be controlled in real time based on the real-time position information of the moving contactable point and the first support member 6, according to the deviation between these two position information, until the first support member 6 is hoisted onto the contactable point on the wet-film substrate 4, completing the hoisting. Similarly, the process of transferring the wet-film substrate 4 to the discharge conveyor 3 can also be controlled in real time based on the real-time position information of the support protrusion 31 on the moving discharge conveyor 3 and the first support member 6, according to the deviation between these two position information, until the contactable point on the wet-film substrate 4 falls onto the corresponding support protrusion 31, completing the transfer. This application is not limited to the control methods listed above; any method that can complete the hoisting and transfer of the wet-film substrate 4 will suffice.

[0098] Three pairs of first support members 6 are used to lift the three pairs of contact points 41 on the wet-film substrate 4 at intervals, improving lifting stability and balancing force. Alternatively, any two pairs of contact points 41 on the wet-film substrate 4 can be lifted using two pairs of first support members 6, with the remaining contact points 41 resting on the support protrusions 31 on the discharge conveyor 3. By presetting the number of pairs of first support members 6 and the corresponding lifting positions of the first support members 6 and the contact points 41 on the wet-film substrate 4, and also presetting the number of pairs of support protrusions 31 on the discharge conveyor 3 and the corresponding supporting positions of the support protrusions 31 and the contact points 41 on the wet-film substrate 4, the wet-film substrate 4 can be lifted and transported without damaging the wet film outside the contact points 41.

[0099] like Figure 5 As shown, in some embodiments, the substrate glue coating and conveying device further includes a heating unit 8, which is disposed on the conveying path of the discharge conveyor belt 3 and is used to heat and cure the wet film on the wet film substrate 4. The heating unit can be a hot air curing unit, such as a tunnel oven, or an electric heating curing unit or a light curing unit.

[0100] During operation, the wet film substrate 4 transported on the discharge conveyor 3 passes through the heating unit, where the heating unit heats the wet film on the wet film substrate 4 to remove solvent, solidify, and pre-bake. By solidifying the transported wet film substrate 4, damage to the wet film on the wet film substrate 4 during transportation and transfer can be reduced.

[0101] like Figure 5As shown, further, in this embodiment, the substrate glue coating conveying device further includes at least two pairs of second support components 7. The first support component 6, the heating unit 8, and the second support component 7 are arranged sequentially along the conveying direction. The at least two pairs of second support components 7 are arranged sequentially along the conveying direction. The second support components 7 are provided with lifting protrusions 63, which are used to support corresponding contact points 41. Each pair of second support components 7 is used to lift the contact points 41 on both sides of the wet film substrate 4. A controller is in communication with the second support components 7 and is further used to control the at least two pairs of second support components 7 to transfer the wet film substrate 4 away from the discharge conveyor belt 3. The second support components 7 and the first support components 6 can have the same structure and the same lifting principle.

[0102] For example, let's take the example of two rows of contact points 41 on the wet-film substrate 4, where the two rows correspond to each other, forming five pairs of contact points 41: Aa, Bb, Cc, Dd, and Ee. When the two pairs of support protrusions 31 of the discharge conveyor belt 3 support the second pair of contact points Bb and the fourth pair of contact points Dd, respectively, and when the wet-film substrate 4 needs to be transferred, the controller controls the two pairs of second support members 7 to respectively lift the first pair of contact points Aa and the fifth pair of contact points Ee and transfer them.

[0103] When the above technical solution is adopted, after the wet film curing and pre-baking are completed, the controller controls the second supporting component 7 to transfer the wet film substrate 4 away from the discharge conveyor belt 3, and the lifting protrusions 63 on the second supporting component 7 are supported and contacted with the contactable points 41 on the wet film substrate 4. Therefore, the wet film will not be damaged during the transfer process of the wet film substrate 4.

[0104] like Figure 10 As shown, the first support member 6 and the second support member 7 are each L-shaped. The L-shaped structure includes a connected vertical portion 61 and a horizontal portion 62. For example, the vertical portion 61 and the horizontal portion 62 can be rod-shaped or plate-shaped. A lifting protrusion 63 is provided on the horizontal portion 62. The lifting protrusion 63 can be a cylindrical or rectangular column structure. The distance between the two most distant points on the cross section of the lifting protrusion 63 is 0.5 mm to 5 mm. By providing a smaller support cross section, damage to the wet film is reduced. The horizontal portion 62 of the L-shaped structure extends below the wet film substrate 4, and the lifting protrusion 63 on the horizontal portion 62 supports the contactable point 41 of the wet film substrate 4. This prevents contact between the first and second support members 6 and 7 and other parts of the wet film substrate 4, protecting the wet film from damage.

[0105] like Figure 5As shown, further, in this embodiment, the discharge conveyor belt 3 is a closed-loop conveyor belt that moves in a circular motion in one direction, and the conveying path of the discharge conveyor belt 3 passes through the material receiving station, the heating station, the transfer station and the cleaning and drying station in sequence; the first supporting component 6 is used to transfer the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3 at the material receiving station, the heating unit 8 is arranged at the heating station, and the second supporting component 7 is used to transfer the wet film substrate 4 away from the discharge conveyor belt 3 at the transfer station; the substrate glue coating and conveying device also includes a cleaning and drying unit 9, which is arranged at the cleaning and drying station of the discharge conveyor belt 3, and is used to clean and dry the discharge conveyor belt 3 that has passed the cleaning and drying station.

[0106] When the above technical solution is adopted, the discharge conveyor belt 3 is a closed-loop conveyor belt that moves in a circular motion, and the wet film substrate 4 is placed on the discharge conveyor belt 3 at the splicing station. Then, the discharge conveyor belt 3 drives the wet film substrate 4 to move to the heating station for heating and curing. After that, the discharge conveyor belt 3 drives the wet film substrate 4 to move to the transplanting station, and the wet film substrate 4 is transferred away from the discharge conveyor belt 3 by the second supporting component 7. Finally, the empty discharge conveyor belt 3 moves to the cleaning and drying station to complete the cleaning of the discharge conveyor belt 3, and then returns to the splicing station to continue conveying the wet film substrate 4.

[0107] In some embodiments, position detection component 5 is an image sensor, such as a CCD (Charge Coupled Device) camera. The image sensor detects image information, and the controller obtains the relative position deviation value based on the image information. This provides more accurate and clear image information, more precise detection, and improved control accuracy. Of course, position detection component 5 can also be a laser position sensor, etc., as long as it can achieve position detection, and is not limited to the forms listed in this embodiment.

[0108] like Figure 3 、 Figure 5-Figure 9 As shown, in some possible implementations, the coating mechanism 2 includes two sets of glue coating components, which are respectively arranged above and below the substrate to be coated, and are used to apply glue to the upper surface and lower surface of the substrate to be coated. Each set of glue coating components includes a glue outlet device (not shown) and a coating roller 23. The glue outlet device is arranged at the discharge end of the feed conveyor mechanism 1, and the glue outlet device has a glue dripping port 22; the coating roller 23 is rotatably arranged below the glue dripping port 22 of the glue outlet device, and the glue dripping port 22 provides glue to the surface of the coating roller 23. The coating roller 23 is used to contact the surface of the substrate to be coated so that the glue covering the surface of the coating roller 23 is coated on the upper surface, lower surface and side surface of the substrate to be coated. In this way, through the rolling contact between the coating roller 23 and the substrate to be coated, the glue on the surface of the coating roller 23 is coated on the surface of the substrate to be coated, so that the substrate is smoothly transported and glue is also applied to its surface.

[0109] In some embodiments, the coating mechanism 2 further includes a glue spreading roller 21, which is rotatably disposed below the glue drop port 22 and in rolling contact with the coating roller 23, for evenly coating the surface of the coating roller 23 with glue. In this way, by disposing the glue spreading roller 21 and bringing it into rolling contact with the coating roller 23, the glue liquid discharged from the glue drop port 22 can be dropped at a position where the glue liquid contacts the coating roller 23, and the glue liquid can be evenly coated on the surface of the coating roller 23 by rotating and squeezing the glue liquid relative to each other. The coating roller 23 is in rolling contact with the substrate, which can achieve even coating on the surface of the substrate to be coated, thereby improving the glue coating quality of the substrate to be coated and ensuring a uniform glue coating thickness on the substrate surface.

[0110] like Figure 3 、 Figure 5-Figure 9 As shown, in some embodiments, the feed conveyor mechanism 1 includes a plurality of conveyor rollers arranged side by side, and the plurality of conveyor rollers can be driven by a power component, and the plurality of conveyor rollers are connected to each other by transmission. For example, a main conveyor roller is driven to rotate by a power component, and the rest are driven conveyor rollers and are connected to the main conveyor roller by a transmission chain or a transmission gear. Alternatively, each conveyor roller is driven to rotate by a power component alone, as long as it can provide power for the conveyor roller, and is not limited to the forms listed in this embodiment. The conveyor roller is in rolling contact with the surface of the substrate to be coated, and is used to transport the substrate to be coated from the loading end to the discharging end. In this way, the substrates to be coated can be placed one by one at the loading end of the conveyor roller and transported to the discharging end. Of course, the feed conveyor mechanism 1 can also use a conveyor belt.

[0111] Based on the substrate gluing conveying device described in any of the above embodiments, an embodiment of the present invention further provides a control method for the substrate gluing conveying device, wherein the substrate gluing conveying device includes a feeding conveying mechanism 1, a coating mechanism 2, and a discharging conveyor belt 3 arranged in sequence along a conveying direction. The control method for the substrate gluing conveying device includes the following steps:

[0112] Step S100: conveying the substrate to be coated to the coating mechanism 2 via the feed conveyor mechanism 1; wherein the lower surface of the substrate to be coated has at least one row of contact points 41 spaced apart along the conveying direction of the substrate to be coated;

[0113] Step S200 , using the coating mechanism 2 to coat the upper surface, lower surface and side surfaces of the substrate to be coated with a wet film to form a wet film substrate 4 ;

[0114] Step S300 , in the process of transferring the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor 3 , the position information of the wet film substrate 4 is obtained by the position detection component 5 ;

[0115] Step S400, the controller controls according to the position information, so that the wet film substrate 4 can contact the corresponding contact point 41 on the support protrusion 31 on the discharge conveyor belt 3 during transmission.

[0116] The technical effect realized by the control method of the substrate coating conveying device is the same as the technical effect described above. During the transmission of the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt, the position detection component 5 obtains the position information of the wet film substrate 4, and the controller controls according to the position information, so that the contactable point 41 on the wet film substrate 4 corresponds to the contact of the support protrusion 31 on the discharge conveyor belt 3. Because the contactable point 41 on the lower surface of the substrate to be coated is arranged along the conveying direction, the contactable point 41 can be contacted, and the wet film on the contactable point 41 can be exposed without affecting the subsequent process, avoiding damage to the wet film on the wet film substrate 4 outside the contactable point 41.

[0117] In the embodiment, a specific control method of the substrate coating conveying device is provided, wherein during the process of transferring the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3 in step S300, the position detection component 5 obtains the position information of the wet film substrate 4, which specifically includes:

[0118] Step S300', during the process of transferring the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor belt 3, the position detection component 5 obtains the image information of the side edge of the wet film substrate 4 close to the discharge conveyor belt 3 and the support protrusion 31 close to the wet film substrate 4 on the discharge conveyor belt 3.

[0119] Correspondingly, in step S400, the controller controls according to the position information, so that the wet film substrate 4 can contact the corresponding contact point 41 on the support protrusion 31 on the discharge conveyor belt 3 during transmission, which specifically includes:

[0120] Step S400', the controller determines the relative position deviation value between the contactable point 41 close to the discharge conveyor belt 3 on the wet film substrate 4 and the support protrusion 31 for supporting the contactable point 41 according to the image information, and controls the conveying speed of the discharge conveyor belt 3 according to the relative position deviation value, so that the wet film substrate 4 can contact the support protrusion 31 during transmission.

[0121] The specific working principle of the method is described in the description of any one of the embodiments shown in the above substrate coating conveying device Figure 3 and Figure 4 The detailed description of the above substrate coating conveying device is not repeated here.

[0122] When adopting the above technical solution, when the distance between one side edge of the wet film substrate 4 close to the discharge conveyor belt 3 and the contactable point 41 on the wet film substrate 4 closest to the side edge, and the distance between two adjacent supporting protrusions 31 on the discharge conveyor belt 3 are known in advance, a relative position deviation value can be obtained based on the image information of the one side edge of the wet film substrate 4 close to the discharge conveyor belt 3 and the supporting protrusion 31 on the discharge conveyor belt 3 close to the wet film substrate 4. Afterwards, the controller controls the instantaneous conveying speed of the discharge conveyor belt 3 according to the relative position deviation value, and adjusts the distance between the supporting protrusion 31 on the discharge conveyor belt 3 and the contactable point 41 to be supported in the conveying direction, so that the contactable point 41 on the wet film substrate 4 closest to the one side edge first contacts the supporting protrusion 31 on the discharge conveyor belt 3, thereby avoiding damage to the wet film of the wet film substrate 4 during transportation.

[0123] Furthermore, in this embodiment, the substrate glue coating and conveying device further includes a position adjustment mechanism, the controller is in communication connection with the position adjustment mechanism, and the position adjustment mechanism is in driving connection with the discharge conveyor belt 3; then in step S400, the controller performs a control operation according to the position information so that during the transmission of the wet film substrate, the contact point 41 contacts the support protrusion 31 on the discharge conveyor belt 3, and further includes the following steps:

[0124] The controller is also used to control the action of the position adjustment mechanism according to the relative position deviation value, so that the position adjustment mechanism drives at least one end of the discharge conveyor belt 3 close to the coating mechanism 2 to move in the horizontal direction of the conveying direction.

[0125] If there is a position deviation between the support protrusion 31 on the discharge conveyor belt 3 and the contactable point 41 on the wet film substrate 4 that is about to contact in the horizontal direction perpendicular to the conveying direction, the controller can also control the position adjustment mechanism to move at least one end of the discharge conveyor belt 3 close to the coating mechanism 2 in the horizontal direction perpendicular to the conveying direction, and adjust the position of the support protrusion 31 on the discharge conveyor belt 3 so that the support protrusion 31 on the discharge conveyor belt 3 contacts the contactable point 41 on the wet film substrate 4. The specific working principle of this method can be found in the above-mentioned substrate glue coating conveying device. Figure 3 and Figure 4 The description of any of the embodiments shown will not be repeated here.

[0126] In some embodiments, another control method for a substrate glue coating conveying device is provided. The difference from the above control method is steps S300 and S400.

The first support members 6 are provided with lifting protrusions 63, which are used to support corresponding contact points 41. Each pair of first support members 6 is used to lift the contact points 41 on both sides of the wet film substrate 4. The controller is in communication with the first support members 6.

[0127] In step S300, during the process of transferring the wet film substrate 4 from the coating mechanism 2 to the discharge conveyor 3, the position information of the wet film substrate 4 is obtained by the position detection component 5, specifically including:

[0129] Accordingly, in step S400, the controller performs control operations according to the position information so that the contact points 41 of the wet film substrate 4 contact the supporting protrusions 31 on the discharge conveyor belt 3 during the transmission process, specifically including:

[0130] In step S400, the controller controls the at least two pairs of first supporting members 6 to sequentially lift the contactable points 41 of the wet-film substrate 4 that are gradually moved out of the coating mechanism 2 and exposed, based on the position information and the position of the first supporting members 6. The controller also controls the at least two pairs of first supporting members 6 to lift and transfer the wet-film substrate 4 from the coating mechanism 2 to the discharge conveyor 3, and ensures that the supporting protrusions 31 on the discharge conveyor 3 are supported on the contactable points 41 of the wet-film substrate 4.

[0131] The specific working principle of this method can be found in the above substrate glue coating conveying device. Figure 5-Figure 9 The description of any of the embodiments shown will not be repeated here.

[0132] When the above technical solution is adopted, since the contactable points 41 of the wet film substrate 4 are supported by the lifting protrusions 63 of the first supporting component 6 and lifted and transported to the discharge conveyor 3, damage to the wet film in areas other than the contactable points 41 on the wet film substrate 4 is avoided.

[0133] Furthermore, in this embodiment, the substrate glue coating conveying device further includes at least two pairs of second support members 7, the first support members 6 and the second support members 7 are sequentially arranged along the conveying direction, and the at least two pairs of second support members 7 are sequentially arranged along the conveying direction, and the second support members 7 are provided with lifting protrusions 63, and the lifting protrusions 63 are used to support the contactable points 41 correspondingly, and each pair of second support members 7 is respectively used to lift the contactable points 41 on both sides of the wet film substrate 4; the controller is in communication with the second support members 7;

[0134] After step S400 ″, the process further includes step S500 , where the controller controls at least two pairs of second supporting components 7 to transfer the wet film substrate 4 away from the discharge conveyor belt 3 .

[0135] The working principle of step S500 can be found in the above substrate glue coating and conveying device. Figure 5-Figure 9 The description of any of the embodiments shown will not be repeated here.

[0136] When the above technical solution is adopted, the controller controls the second supporting component 7 to transfer the wet film substrate 4 away from the discharge conveyor belt 3, and the lifting protrusion 63 on the second supporting component 7 is supported and contacted with the contactable point 41 on the wet film substrate 4. Therefore, during the process of transferring the wet film substrate 4, the wet film will not be damaged.

[0137] In this embodiment, before step S500, that is, during the process of the discharge conveyor belt 3 transporting the wet film substrate 4, and before the controller controls the at least two pairs of second support components 7 to transfer the wet film substrate 4 away from the discharge conveyor belt 3, the step of heating the wet film substrate 4 transported on the discharge conveyor belt 3 by the heating unit 8 to remove the solvent and perform a curing process.

[0138] Furthermore, in this embodiment, after step S500, that is, after the controller controls at least two pairs of second support components 7 to transfer the wet film substrate 4 away from the discharge conveyor belt 3, step S600 is also included: the discharge conveyor belt 3 that moves through the cleaning and drying station is cleaned and dried by the cleaning and drying unit 9.

[0139] The working principle of step S600 can be found in the above substrate glue coating and conveying device. Figure 5 The description of the illustrated embodiment will not be repeated here.

[0140] When the above technical solution is adopted, after the wet film substrate 4 is transferred away from the discharge conveyor belt 3, the unloaded discharge conveyor belt 3 moves to the cleaning and drying station to complete the cleaning of the discharge conveyor belt 3, and the wet film substrate 4 can be transported in a cycle to avoid contamination of the wet film by residual substances on the discharge conveyor belt.
