Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaics, and in particular relates to a glass cross-cutting removal process for a single-glass component. Background Art

[0002] Single-glass photovoltaic modules are referred to as single-glass modules for short, which mainly include solar cells, glass layers and backboard layers formed on the front and back sides of the solar cells, and junction boxes arranged on the glass layers.

[0003] At present, in the glass removal process of a single-glass component, the removal device used includes a pretreatment unit and a stripping unit, wherein the pretreatment unit pretreats the glass layer by means of preheating or pre-crushing to reduce the difficulty of stripping, and then the stripping unit forms a stripping force to remove the glass layer, wherein the stripping unit includes a stripping transmission roller, a stripping tool, and a driver that drives the stripping tool to form cutting, that is, the glass layer is removed by the movement of the stripping tool under the forward transmission of the stripping transmission roller.

[0004] However, no matter it is the deformation of the components caused by recycling or the deformation of the components themselves, after pre-treatment, if they are not effectively shaped, they will not be able to enter the stripping unit relatively smoothly, causing the cutting amount formed by the stripping tool to be uncontrollable. At the same time, the friction between the upper roller and the lower roller of the stripping transmission roller used is different (because the lower roller is in contact with the glass layer). Therefore, the battery cell maintains an upward movement. If the battery cell discharge angle is not restricted, the cutting position will inevitably be unstable, that is, the stripping rate cannot meet the requirements (the glass residual rate is high), and the probability of the battery cell being damaged is high. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved glass cross-cutting removal process for a single-glass component.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] A glass cross-cut removal process for a single glass component, wherein the glass cross-cut removal device used comprises a pretreatment unit and a stripping unit, wherein the pretreatment unit comprises a preheating furnace, the stripping unit comprises a stripping seat, a stripping transmission roller, and a cutting tool, the glass cross-cut removal device further comprises a component shaping mechanism disposed between the preheating furnace and the stripping transmission roller, and a temperature-controlled heater disposed in the component shaping mechanism, the stripping unit further comprises a secondary stripping roller located above the cutting tool, and the glass cross-cut removal process comprises the following steps:

[0008] S1. Preheating: using a preheating furnace to preheat the single-glass component to soften the glue layer;

[0009] S2, temperature control shaping, the preheated single-glass component enters the component shaping mechanism with the glass facing downward, and is flattened by multiple sections formed by multiple shaping mold strips arranged side by side on the annular mesh conveyor belt to level the single-glass component, wherein the temperature control heater selectively heats according to the heat dissipation of the single-glass component to continuously soften the glue layer;

[0010] S3, cross-cutting the glass. The leveled component horizontally enters between the upper roller and the lower roller of the stripping transmission roller and is gradually pushed forward. At the same time, the cutting tool at the front end reciprocates along the width direction of the single-glass component to cross-cut the glass layer of the single-glass component. The cell with the glass cut off tilts upward and is transported upward under the action of the secondary stripping roller while maintaining the movement trend of the upper roller in contact with the surface of the cell.

[0011] S4, the battery cells are collected. When the upper roller and the secondary stripping roller move toward each other, the battery cells are rolled backward and placed on a plurality of shaping mold strips.

[0012] According to a specific implementation and preferred aspect of the present invention, the secondary peeling roller includes a roller body and a brushing body formed in the circumference of the roller body, wherein the brushing body contacts the battery cell and brushes the peeling surface of the battery cell as the roller body rotates. Here, the main functions of the secondary peeling roller are: 1) to make the battery cell keep in contact with the movement trend of the upper roller to implement cross-cutting, so as to ensure the accuracy of the cross-cutting position, thereby improving the peeling rate and reducing the battery cell damage rate; 2) to assist in discharging, so that the battery cell moves upward and backward to curl; 3) to brush the broken glass in a brushing manner, which can also achieve a certain peeling effect.

[0013] In some specific embodiments, the brushing body comprises a steel wire body, wherein the steel wire body has one or more wires. That is, a conventional steel wire roller is used to implement brushing.

[0014] According to another specific implementation and preferred aspect of the present invention, the stress applied by the upper roller to the battery cell is at least twice the sweeping force applied by the secondary stripping roller to the battery cell. This more effectively completes the back-rolling of the battery cell, where the material collection can be done manually, and multiple battery cells can also be temporarily piled up on multiple shaping mold strips.

[0015] Preferably, the distance between the secondary peeling roller and the upper roller is equal to the thickness of the battery sheet, so as to ensure stable lamination and provide relatively stable working conditions for cross-cutting.

[0016] In some specific embodiments, the centers of the secondary stripping roller, the upper roller, and the lower roller form a right triangle, wherein the center line between the upper roller and the lower roller forms a right angle side; the center line between the upper roller and the secondary stripping roller forms another right angle side; and the center line between the lower roller and the secondary stripping roller forms a hypotenuse. This layout can more stably implement the cell winding and is also convenient for cross-cutting.

[0017] According to another specific implementation and preferred aspect of the present invention, the endless mesh conveyor crosses the preheating furnace and is exposed from the end thereof, wherein a component shaping mechanism is formed between the exposed end of the endless mesh conveyor and a plurality of shaping mold strips, wherein the plurality of shaping mold strips are evenly distributed along the width direction of the endless mesh conveyor. Based on the temperature of the endless mesh conveyor itself, the pre-peeling temperature control is implemented more energy-efficiently to keep the adhesive layer in a softened state for cross-cutting.

[0018] Preferably, each shaping mold strip is divided into a guide section and a flattening section along the transmission direction of the single-glass component, wherein the distance between the guide section and the annular mesh conveyor gradually decreases along the transmission direction of the single-glass component, and the distance between the guide section and the annular mesh conveyor is greater than or equal to the thickness of the single-glass component, and the flattening section is arranged in parallel with the annular mesh conveyor, and the distance between the flattening section and the annular mesh conveyor is less than or equal to the thickness of the single-glass component. A guide is formed by guiding, and then gradually shaped in the flattening section, so that a relatively flat single-glass component enters between the upper and lower rollers.

[0019] Furthermore, each shaping mold strip can be mounted on the stripping seat in an adjustable manner up and down to meet the stripping operation of single-glass components of different thicknesses.

[0020] In some specific embodiments, the guide section includes a front guide section and a rear guide section with gradually decreasing inclination rates; the battery sheet curled backward moves from the front guide section or the rear guide section to the flattening section. This design is not only for forming a feed guide, but also for facilitating the collection and guidance of the rolled battery sheets.

[0021] Preferably, the length of the endless mesh conveyor exposed from the preheating furnace is L1, the length of the lead section is L2, and the length of the flattening section is L3, wherein L1 / 2≤L2+L3≤4L1 / 5. This length design not only meets the shaping needs, but also meets the winding needs.

[0022] According to another specific implementation and preferred aspect of the present invention, the temperature control heater includes electric heating rods arranged side by side along the transmission direction of the single glass component and inside the exposed preheating furnace portion of the annular mesh conveyor, wherein a plurality of electric heating rods are connected in series and / or in parallel. The circuit control based on the electric heating rods satisfies the softening of the glue layer under different working conditions (e.g., level 4 ambient temperature).

[0023] Preferably, a heat insulation board is installed at the bottom of the electric heating rod to reduce energy waste and loss.

[0024] Preferably, in S1, the preheating temperature is 80-120°C, and generally around 100±5°C.

[0025] In addition, the stripping seat can be slidably adjusted along the transmission direction of the single-glass component to adjust the cutting position, and the cutting position is close to the tangent point between the lower roller and the single-glass component. The layout of the tangent point position can avoid excessive protrusions causing the cross-cut cells to shift in the left and right directions. At the same time, based on the position adjustment, it is more convenient in case of material jamming or the need to change the knife.

[0026] Furthermore, a receiving hopper is provided at the bottom of the stripping conveying roller and the cutting tool, wherein the receiving hopper collects the broken glass after cutting and secondary stripping or brushing. The collection of broken glass is completed based on the receiving hopper.

[0027] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0028] In the existing single-glass component glass removal, no matter it is the component deformation caused by recycling or the component itself, after pre-treatment, if it is not effectively shaped, it will not be able to enter the stripping unit relatively smoothly, resulting in the uncontrollable cutting amount formed by the stripping tool. At the same time, the friction between the upper roller and the lower roller of the stripping transmission roller used is different (because the lower roller contacts the glass layer). Therefore, the battery cell maintains an upward movement mode of transmission. If the battery cell discharge angle is not restricted, it is bound to cause an unstable cutting position, that is, the stripping rate cannot meet the requirements (high glass residual rate), and the probability of battery cell damage is high, etc. The present application comprehensively designs the glass cross-cutting removal process of the single-glass component, cleverly solving the shortcomings and defects of the prior art. After adopting the process, first, a preheating furnace is used to preheat the single-glass component to soften the glue layer; then, the preheated single-glass component enters the component shaping mechanism from the glass downward, The single-glass component is leveled by a multi-stage flattening process formed by a plurality of shaping mold strips arranged side by side on the annular mesh conveyor, wherein the temperature-controlled heater selectively heats according to the heat dissipation of the single-glass component to continuously soften the glue layer; then, the leveled component horizontally enters between the upper roller and the lower roller of the stripping transmission roller and is gradually pushed forward, while the cutting tool at the front end reciprocates along the width direction of the single-glass component to cross-cut the glass layer of the single-glass component being transmitted out, and the cell with the glass cut off tilts upward and is transmitted upward under the action of the secondary stripping roller while maintaining the movement trend of the upper roller in contact with the surface of the cell; finally, the cell is curled backward and mounted on a plurality of shaping mold strips as the upper roller and the secondary stripping roller move toward each other. Therefore, compared with the prior art, the present invention is based on leveling and temperature control of the softening of the glue layer, and at the same time, in the secondary peeling roller guided discharge, the battery cell is relatively attached to the upper roller, and the cutting position and cutting amount are kept stable, high-quality cross-cutting, and then the secondary peeling is formed by the secondary peeling roller, which not only greatly improves the peeling rate, but also greatly reduces the battery cell damage rate; on the other hand, the battery cell collection method formed not only relies on the upper roller and the secondary peeling roller to move towards each other, but also needs to use the leveled shaping mold strip again for curling and collection, so as to implement the multi-purpose components and complete the battery cell collection in a small space requirement, which is highly practical.

[0045] like Figures 1 to 7 As shown, the glass cross-cutting removal device involved in this embodiment includes a pretreatment unit 1 and a stripping unit 2, wherein the pretreatment unit 1 includes a preheating furnace 10, a component shaping mechanism 11 arranged between the preheating furnace 10 and the stripping unit 2, and a temperature-controlled heater 12 arranged in the component shaping mechanism 11; the stripping unit 2 includes a stripping seat 20, a stripping transmission roller 21, a cutting tool 22, and a secondary stripping roller 23 located above the cutting tool 22.

[0046] Specifically, the preheating furnace 10 is an ordinary heating furnace, which adopts a heating roller or a heating wire to perform heating, and the heating temperature formed is 100±5°C. At the same time, the single glass component m is transported forward from the glass layer m2 downward along the annular mesh conveyor 100, wherein the front end of the annular mesh conveyor 100 is exposed at the outlet of the heating furnace, and the exposed end of the annular mesh conveyor 100 constitutes a part of the component shaping mechanism 11 (the movement of the annular mesh conveyor 100 adopts a conventional transmission sprocket method).

[0047] In some specific embodiments, the component shaping mechanism 11 includes an exposed end of an annular mesh conveyor belt 100, and a plurality of shaping mold bars 110 arranged side by side on the exposed end of the annular mesh conveyor belt 100, wherein the plurality of shaping mold bars 110 and the annular mesh conveyor belt 100 are formed between multiple sections to flatten the single glass component. The temperature control heater 12 selectively heats according to the heat dissipation of the single glass component to continuously soften the glue layer. Specifically, the temperature control heater 12 includes electric heating rods 120 distributed side by side along the transmission direction of the single glass component inside the exposed preheating furnace part of the annular mesh conveyor belt 100, wherein the plurality of electric heating rods 120 are connected in series and / or in parallel. The circuit control based on the electric heating rod is to meet the softening of the glue layer under different working conditions (such as: level 4 ambient temperature). Furthermore, a heat insulation board 121 is installed at the bottom of the electric heating rod 120. To reduce energy waste and loss.

[0048] In this example, multiple shaping molds 110 are evenly distributed along the width direction of the annular mesh conveyor 100. Based on the temperature of the annular mesh conveyor itself, the pre-stripping temperature control is implemented more energy-efficiently to keep the glue layer in a softened state for cross-cutting. And each shaping mold 110 is divided into a connecting section a and a flattening section b along the transmission direction of the single glass component, wherein the distance between the connecting section a and the annular mesh conveyor 100 gradually decreases along the transmission direction of the single glass component, and the distance between the connecting section a and the annular mesh conveyor 100 is greater than or equal to the thickness of the single glass component, and the flattening section b is arranged parallel to the annular mesh conveyor 100, and the distance between the flattening section b and the annular mesh conveyor 100 is less than or equal to the thickness of the single glass component m. The guide is formed by the connecting, and then the shaping is gradually performed in the flattening section, so that the relatively flat single glass component m enters between the upper and lower rollers. At the same time, each shaping mold 110 can be installed on the stripping seat so as to be adjustable up and down. To meet the stripping operation of single glass components of different thicknesses.

[0049] Furthermore, the length of the annular mesh conveyor exposed to the preheating furnace is L1, the length of the connecting section is L2, and the length of the flattening section is L3, where L1 / 2≤L2+L3≤4L1 / 5. This length design not only meets the shaping needs, but also meets the winding needs. The connecting section a includes the front connecting section a1 and the rear connecting section a2 with gradually decreasing inclination rates; the front and rear connecting sections are designed here mainly to facilitate the movement and guidance of the battery cells that are curled backward from the front connecting section or the rear connecting section to the flattening section. That is, it is not only for the purpose of forming a feed guide, but also for the collection and guidance of the rolled battery cells.

[0050] As for the peeling unit 2, its structure is relatively conventional. The peeling transmission roller 21 includes an upper roller 21a and a lower roller 21b installed on the peeling seat 20, and the distance between the upper roller 21a and the lower roller 21b is adjustable to meet the passing of components of different thicknesses. The cutting tool 22 adopts a conventional cutting seat 220, a plurality of cutting tools 221 installed on the cutting seat 220, and a power member 222 that drives the cutting seat 220 to reciprocate along the width direction of the component to form cutting. The power member 222 adopts an eccentric wheel and a connecting rod transmission method to implement reciprocating motion (which is a conventional transmission method in this field).

[0051] However, in this example, the secondary peeling roller 23 includes a roller body 230 and a brushing body 231 formed around the roller body 230, wherein the brushing body 231 contacts the cell m1 and brushes the peeling surface of the cell as the roller body 230 rotates. Here, the main functions of the secondary peeling roller are: 1) to make the cell keep in contact with the movement trend of the upper roller to implement cross-cutting, so as to ensure the accuracy of the cross-cutting position, thereby improving the peeling rate and reducing the cell damage rate; 2) to assist in discharging, so that the cell moves upward and backward to curl; 3) to brush the broken glass by brushing, which can also achieve a certain peeling effect.

[0052] In some specific embodiments, the brushing body 230 includes a steel wire body, wherein the steel wire body has one or more wires. That is, a conventional steel wire roller is used for brushing. At the same time, the stress applied by the upper roller 21a to the battery cell m1 is at least twice the brushing force applied by the secondary stripping roller 23 to the battery cell. In this way, the battery cell is more effectively collected into a roll, and the collection here can be done manually, and multiple battery cells can also be temporarily piled up on multiple shaping molds. The distance between the secondary stripping roller 23 and the upper roller 21a is equal to the thickness of the battery cell. In this way, the bonding is stable and a relatively stable working condition is provided for cross-cutting. The centers of the secondary stripping roller 23, the upper roller 21a, and the lower roller 21b form a right triangle, wherein the center line between the upper roller 21a and the lower roller 21b forms a right angle side; the center line between the upper roller 21a and the secondary stripping roller 23 forms another right angle side; and the center line between the lower roller 21b and the secondary stripping roller 23 forms a hypotenuse. This layout makes it possible to more stably roll up the battery cells and also facilitate cross-cutting.

[0053] In addition, the stripping seat 20 can be slidably adjusted along the transmission direction of the single-glass component to adjust the cutting position, and the cutting position is close to the tangent point between the lower roller 21b and the single-glass component. The layout of the tangent point position is to avoid excessive growth and cause the cross-cutting cell m1 to shift in the left and right directions. At the same time, based on the position adjustment, it is more convenient in case of material jamming or the need to change the knife.

[0054] A receiving hopper 24 is also provided at the bottom of the stripping conveying roller 21 and the cutting tool 22, wherein the broken glass after cutting, secondary cutting or brushing is collected by the receiving hopper 24. The collection of broken glass is completed based on the receiving hopper.

[0055] In summary, the implementation process of this embodiment is as follows:

[0056] S1. Preheating: Use a preheating furnace to preheat the single-glass component to soften the glue layer, with the glass layer facing downward and the temperature at 100±5℃;

[0057] S2, temperature control shaping, the preheated single-glass component enters the component shaping mechanism with the glass facing downward, and is flattened by multiple sections formed by multiple shaping mold strips arranged side by side on the annular mesh conveyor belt to level the single-glass component, wherein the temperature control heater selectively heats according to the heat dissipation of the single-glass component to continuously soften the glue layer;

[0058] S3, cross-cutting the glass. The leveled component horizontally enters between the upper roller and the lower roller of the stripping transmission roller and is gradually pushed forward. At the same time, the cutting tool at the front end reciprocates along the width direction of the single-glass component to cross-cut the glass layer of the single-glass component. The cell with the glass cut off tilts upward and is transported upward under the action of the secondary stripping roller while maintaining the movement trend of the upper roller in contact with the surface of the cell.

[0059] S4, the battery cells are collected. When the upper roller and the secondary stripping roller move toward each other, the battery cells are rolled backward and placed on a plurality of shaping mold strips.

[0060] In summary, after adopting this process, first, a preheating furnace is used to preheat the single-glass component to soften the glue layer; then, the preheated single-glass component enters the component shaping mechanism from the glass downward, and is flattened by multiple shaping mold strips arranged side by side on the annular mesh conveyor belt to level the single-glass component, wherein the temperature-controlled heater selectively heats according to the heat dissipation of the single-glass component to continuously soften the glue layer; then, the leveled component enters horizontally between the upper roller and the lower roller of the stripping transmission roller, and is gradually pushed forward, while the cutting tool at the front end reciprocates along the width direction of the single-glass component to cross-cut the glass layer of the single-glass component transmitted out, and the cell with the glass cut off is tilted upward and is transmitted upward under the action of the secondary stripping roller while maintaining the movement trend of the upper roller and the cell surface in contact; finally, the cell is curled backward and mounted on multiple shaping mold strips during the opposite movement of the upper roller and the secondary stripping roller. Therefore, compared with the prior art, the present invention is based on leveling and temperature control of the softening of the adhesive layer. At the same time, in the secondary peeling roller guiding the discharge, the cutting position and cutting amount are kept stable in the working condition of the battery cell relatively fitting the upper roller, and the secondary peeling is formed by the secondary peeling roller, which not only greatly improves the peeling rate, but also greatly reduces the battery cell damage rate; on the other hand, the battery cell collection method formed not only relies on the upper roller and the secondary peeling roller to move towards each other, but also needs to use the leveling shaping mold strip again for curling collection, so as to implement the multi-purpose parts and small space required to complete the battery cell collection, which is highly practical; the third aspect is that the use of the secondary peeling roller is the most important The functions are: 1) to make the battery cell keep in contact with the movement trend of the upper roller while performing cross-cutting to ensure the accuracy of the cross-cutting position, thereby improving the peeling rate and reducing the battery cell damage rate; 2) to assist in discharging so that the battery cell moves upward and backward to curl; 3) to use a brushing method to brush away the broken glass, which can also achieve a certain peeling effect; fourthly, the stress applied by the upper roller to the battery cell is at least twice the brushing force applied by the secondary peeling roller to the battery cell, so that the battery cell can be more effectively collected into a roll. The collection here can be done manually, and multiple battery cells can also be temporarily piled up on multiple shaping molds, and the distance between the secondary peeling roller and the upper roller is equal to the thickness of the battery cell. This ensures stable bonding and provides relatively stable working conditions for cross-cutting; fifthly, the centers of the secondary stripping roller, the upper roller, and the lower roller form a right triangle, in which the center line between the upper roller and the lower roller forms a right angle; the center line between the upper roller and the secondary stripping roller forms another right angle; the center line between the lower roller and the secondary stripping roller forms a hypotenuse. With this layout, the cell winding can be more stably implemented, and cross-cutting is also convenient; sixthly, based on the temperature of the annular mesh conveyor belt, the pre-stripping temperature control is implemented more energy-efficiently to keep the glue layer softened for cross-cutting, and at the same time, a guide is formed through connection, and then gradually shaped in the flattening section, so that a relatively flat single-glass component enters between the upper and lower rollers, and each shaping mold strip can be installed on the stripping seat so as to be adjusted up and down.To meet the peeling operation of single-glass components of different thicknesses; the seventh aspect is that the front section and the rear section are not only for forming the feed guide, but also for facilitating the collection and guidance of the rolled battery cells; at the same time, the length of the ring-shaped mesh conveyor exposed to the preheating furnace is L1, the length of the guide section is L2, and the length of the flattening section is L3, where L1 / 2≤L2+L3≤4L1 / 5. This length design not only meets the needs of shaping, but also meets the needs of winding; the eighth aspect is based on the circuit control of the electric heating rod to meet different working conditions (such as: level 4 ambient temperature) The glue layer softens, and an insulation board is installed at the bottom of the electric heating rod to reduce energy waste and loss, generally around 100±5℃; the ninth aspect is the layout of the cutting point position to avoid excessive protrusion, which causes the battery cell to shift in the left and right directions after cross-cutting.
