Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic component recycling, and in particular relates to a glass removing device for a double-glass component. Background Art

[0002] Photovoltaic modules are mainly divided into single-glass modules and double-glass modules. Regardless of the product, the glass panel layer needs to be removed during the recycling process. The conventional methods are: preheating, crushing, and peeling. The peeling methods include shoveling, cutting, etc.

[0003] At present, in the recycling of double-glass modules, it is usually necessary to remove the back glass of the double-glass module before removing the front glass. However, after removing the back glass, the double-glass module generally only has the battery cell and the glass on the front of the battery cell, which is very thin. In addition, due to the soft characteristics of the battery cell, the following defects are prone to occur in the actual removal process of the front glass:

[0004] 1. When the conventional cutter head removes the front glass during the cell transfer process, especially when the glass initially contacts the cutter head, the cell is on one side of the cutter head as a whole. The cell is easily deformed and offset under the cutting force, resulting in the inability to completely remove the front glass and a high glass residue rate.

[0005] 2. When the blade is scraping the front glass, since the front glass is on the upper surface of the battery cell, the glass is easily splashed and accumulated after being broken and separated under the scraping force. It is not only difficult to collect, but also easy to cause collisions to various mechanisms on the recycling equipment and nearby workers, which is destructive and dangerous. Moreover, the accumulated broken glass is easy to affect the subsequent glass removal, and the tool damage rate is high. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new glass removal device for a double-glass assembly.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A glass removal device for a double-glass component, comprising a transmission unit and a cutting unit, wherein the transmission unit comprises a conveyor belt, wherein the double-glass component is placed flat on the conveyor belt with the glass to be removed facing upward and is transmitted from front to rear; the cutting unit comprises a tool arranged above the conveyor belt and forming a cutting area capable of covering a wide width of the glass, and the transmission unit further comprises a motion guide roller and a flattening module arranged above the conveyor belt in sequence front and back, wherein a guide channel is formed between the motion guide roller and the conveyor belt, when the double-glass component enters the guide channel, the motion guide roller synchronously drives the double-glass component to be transmitted backward and forms a motion guide in the front-to-back direction; a flattening channel connected with the guide channel and used for flattening the double-glass component is formed between the flattening module and the conveyor belt, an avoidance gap connected with the flattening channel and avoiding the tool is formed on the flattening module, the tool extends into the avoidance gap and is separated from the edge of the avoidance gap to form a material guide channel, the double-glass component enters the cutting area based on the motion guide formed by the motion guide roller and the flattening of the flattening channel, and as the double-glass component is transmitted backward, broken glass formed by the cutting of the tool moves along the material guide channel;

[0009] The removal device also includes a collection unit for broken glass, which has a negative pressure port arranged above the material guiding channel and forming a negative pressure area capable of covering the material guiding channel. The broken glass is sucked into the negative pressure port under negative pressure and collected.

[0010] According to a specific implementation and preferred aspect of the present invention, the double-glass assembly is divided into a first section and a second section from the back to the front, and the first section gradually passes through the cutting area based on the first section or the second section being in the motion guide and flattening of the flattening channel formed by the motion guide roller, and the second section gradually passes through the cutting area based on the flattening of the flattening channel. Here, the present application adopts the method of removing the glass in sections, which not only ensures that the battery cell does not deform or deflect based on the motion guide and flattening in the removal of the initial section of glass, and ensures that the glass can be completely removed; at the same time, in the removal of the rear section of glass, the stable transmission of the battery cell can be achieved based on flattening.

[0011] Preferably, the length of the double-glass component is L1, and the length of the first section is L2, wherein 0.5L1≤L2≤0.8L1. In other words, based on the segmented layout of the double-glass component, it is ensured that at least 50% to 80% of the glass can be removed based on motion guidance and flattening, which greatly reduces the probability of deformation and displacement of the cell. At the same time, under this layout, the formed glass removal efficiency is good and the removal cost is low.

[0012] According to another specific implementation and preferred aspect of the present invention, a plurality of crushing rods are distributed around the motion guide roller. As the double-glass assembly enters the guide channel, the plurality of crushing rods are gradually inserted into the glass as the motion guide roller rotates and form a driving force to drive the double-glass assembly to be transmitted backward. Here, while forming the motion guide, the glass is pre-crushed to facilitate the cutting of the subsequent tool; at the same time, the wear of the tool is reduced and the service life is extended.

[0013] Preferably, the moving guide roller extends along the width direction of the double-glass assembly, and the multiple breaking rods are divided into multiple first rod groups and second rod groups that are staggered and distributed along the axial direction of the moving guide roller, wherein the multiple breaking rods in each first rod group extend obliquely to the left from the roller surface of the moving guide roller, and the multiple breaking rods in each first rod group extend obliquely to the right from the roller surface of the moving guide roller, and the left-right direction forces formed by squeezing the glass by the multiple first rod groups and the second rod groups and the left-right direction cutting forces formed by the tool on the glass offset each other. Here, by extending the multiple breaking rods obliquely to the left and right sides, while the rear end tool removes the glass, the two groups of breaking rods offset the cutting forces in the left and right directions, further reducing the probability of the photovoltaic assembly being offset; at the same time, by adopting the layout of the breaking rods tilted to the left and right of the present application, the moment the breaking rods touch the glass during rotation, not only can a better breaking effect be achieved, but also the V-shaped space formed between the two adjacent groups of breaking rods is convenient for the discharge of glass fragments, which can effectively prevent the problem of material jamming.

[0014] Preferably, when each breaker bar moves to the lowest point, the length of the breaker bar inserted into the glass is 0.4 to 0.7 times the thickness of the glass. Considering the unevenness of the double-glass assembly during loading, the setting of the breaker bar in this application satisfies the requirements of guiding the movement and pre-breaking the glass while avoiding accidental damage to the battery cell.

[0015] Specifically, the plurality of breaking rods are divided into a plurality of breaking rod groups spaced apart along the axial direction of the moving guide roller, wherein the plurality of breaking rods in each breaking rod group are distributed in a circular array around the center line of the moving guide roller. Here, the breaking force applied to the glass is evenly distributed, which facilitates the subsequent cutting to form broken glass of uniform size.

[0016] Preferably, the flattening module is recessed forward from the rear end to form an avoidance gap. Here, the glass is removed while the battery cell is moved out of the flattening channel, which not only prevents broken glass from falling into the flattening channel and causing material jamming, but also facilitates online quality inspection of the glass removal effect during production and later maintenance.

[0017] Preferably, the tool includes a plurality of disc-shaped cutter heads horizontally arranged above the conveyor belt, and the cutting unit also includes a rotary driver for correspondingly driving each cutter head to rotate around the vertical center line and a lifting driver for correspondingly driving each cutter head to move up and down, wherein the cutting surface formed by the circumference of the plurality of cutter heads constitutes a cutting area; there are a plurality of avoidance gaps and they are arranged one by one corresponding to the plurality of cutter heads. The cutter head used is a grinding disc or a saw disc, that is, the glass is cut and removed by grinding or sawing.

[0018] Specifically, the plurality of cutter heads are divided into a plurality of cutter head groups arranged along the front-to-back direction, wherein the plurality of cutter heads in each cutter head group are arranged side by side and spaced apart from each other, and the cutter heads in adjacent cutter head groups are arranged staggered from front to back, thereby achieving dispersed cutting.

[0019] Furthermore, in the orthographic projection on the horizontal plane, each avoidance gap is in an arc shape concentric with the corresponding blade head; and / or, in the orthographic projection in the left-right direction, the blade heads in adjacent blade head groups are partially overlapped; and / or, in the orthographic projection in the front-back direction, the blade heads in adjacent blade head groups are partially overlapped. Here, based on the layout of the blade heads of the present application, the glass layer can be completely removed with a small number of blade heads, and the structure is simple, which is easy to install and implement.

[0020] Preferably, in each blade group, the rotation direction of a part of the blades is opposite to that of another part of the blades. In other words, in each blade group, there are blades with two rotation directions at the same time, so that the lateral force exerted by the blades on the glass can be offset, and the probability of the double-glass assembly deviating to the left and right directions during the front-to-back transmission can be reduced.

[0021] Preferably, there are two cutter head groups, and the cutting unit further comprises a guide rail extending along the front-rear direction, wherein the cutter head group located in the front is slidably connected to the guide rail through a truss and can be moved forward and backward.

[0022] In addition, the collecting unit includes a collecting box and a negative pressure pipe connected to the collecting box, wherein the negative pressure pipe has a negative pressure port arranged near the material guiding channel, and the broken glass is sucked in and collected in the collecting box through the negative pressure pipe; and / or, there are multiple negative pressure ports and they are arranged correspondingly between every two adjacent cutting heads.

[0023] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0024] When the blade disc used in the prior art removes the front glass during the transmission of the battery cell, especially in the initial contact stage of the glass with the blade disc, the battery cell is entirely on one side of the blade disc, and the battery cell is easily deformed and offset under force, resulting in the inability to completely remove the front glass and a high rate of glass residue. In addition, when the blade disc scrapes the front glass, since the front glass is on the upper surface of the battery cell, the glass is easily splashed and accumulated after being broken and separated under the scraping force, which is not only difficult to collect, but also easy to cause collisions to various mechanisms on the recycling equipment and nearby workers, which is destructive and dangerous to a certain extent. Moreover, the accumulated broken glass is easy to affect the subsequent glass removal, and the tool damage rate is high. The structure of the glass removal device for double-glass components in the present application is The structure is designed as a whole, and the shortcomings and defects of the prior art are cleverly solved. After adopting the glass removal device, the double-glass component is placed flat on the conveyor belt with the glass to be removed facing upward and transmitted from front to rear. The double-glass component enters the guide channel formed between the motion guide roller and the conveyor belt, and the guide channel forms a motion guide for the double-glass component in the front-to-back direction; then the double-glass component enters the flattening channel, and the flattening module flattens the double-glass component to ensure the flatness of the double-glass component; finally, the double-glass component enters the cutting area formed by the tool based on the motion guide formed by the motion guide roller and the flattening of the flattening channel, and as the double-glass component is transmitted backward, the broken glass formed by the cutting of the tool moves along the material guide channel, and the broken glass is sucked into the negative pressure port under negative pressure and collected. Therefore, compared with the prior art, the present invention, on the one hand, starts to remove the glass based on motion guidance and flattening of the double-glass component, effectively reducing the probability of deformation and deviation of the battery cell caused by the cutting force, ensuring that the glass is fully removed during stable transmission, and is very suitable for further removal of the front glass of the double-glass component after removing the back glass; on the other hand, through the material guide channel formed between the tool and the pressure plate, it is ensured that the broken glass generated by cutting is in the material guide channel to reduce splashing, thereby improving production safety, and at the same time, the broken glass in the material guide channel is collected under negative pressure to avoid the accumulation of broken glass affecting the continuous cutting of the tool, effectively extending the service life of the tool and improving the glass removal efficiency.

[0041] like Figures 1 to 6 As shown, the glass removal device of the double-glass component of this embodiment includes a transmission unit 1, a cutting unit 2, and a collection unit 3; the back glass of the double-glass component G of this embodiment has been removed.

[0042] Specifically, the transmission unit 1 includes a frame 10, a conveyor belt 11 installed on the frame 10, a moving guide roller 12 and a flattening module 13 which are arranged in sequence above the conveyor belt 11 and connected to the frame 10, wherein the double-glass assembly G is placed flat on the conveyor belt 11 with the glass B to be removed facing upward and is transmitted from front to back; the cutting unit 2 includes a tool 20 which is arranged above the conveyor belt 11 and forms a cutting area capable of covering a wide width of the glass B, a rotating drive 21 and a lifting drive 22.

[0043] In some specific embodiments, the conveyor belt 11 is an annular conveyor belt of any conventional structure; a guide channel t1 is formed between the motion guide roller 12 and the conveyor belt 11, and when the double-glass component enters the guide channel t1, the motion guide roller 12 is driven by an external power to synchronously rotate to drive the double-glass component G to be transmitted backward and form a motion guide in the front-to-back direction; a flattening channel t2 connected with the guide channel t1 and used to flatten the double-glass component is formed between the flattening module 13 and the conveyor belt 11, and an avoidance gap k connected with the flattening channel t2 and avoiding the tool 20 is formed on the flattening module 13, and the tool 20 extends into the avoidance gap k and is separated from the edge of the avoidance gap k to form a material guide channel t3, and the double-glass component G enters the cutting area based on the motion guide formed by the motion guide roller 12 and the flattening of the flattening channel 13, and as the double-glass component G is transmitted backward, the broken glass formed by the cutting of the tool 20 moves along the material guide channel t3.

[0044] For the convenience of implementation, the double-glass assembly G is divided into the first section G1 and the second section G2 from the back to the front. Based on the first section G1 or the second section G2 being in the motion guide and flattening of the flattening channel 13 formed by the motion guide roller 12, the first section G1 gradually passes through the cutting area, and the second section G2 gradually passes through the cutting area based on the flattening of the flattening channel 13. Here, the present application adopts the method of removing the glass in sections, which not only ensures that the battery cell does not deform or deflect based on the motion guide and flattening in the removal of the initial section of glass, and ensures that the glass can be completely removed; at the same time, in the removal of the rear section of glass, the stable transmission of the battery cell can be achieved based on flattening.

[0045] In some specific embodiments, the length of the double-glass component G is L1, and the length of the first section G1 is L2, where 0.5L1≤L2≤0.8L1. In other words, based on the segmented layout of the double-glass component, it is ensured that at least 50% to 80% of the glass can be removed based on motion guidance and flattening, which greatly reduces the probability of deformation and offset of the cell. At the same time, under this layout, the formed glass removal efficiency is good and the removal cost is low. In this embodiment, preferably, L2=0.7L1.

[0046] In this example, multiple breaking rods 120 are distributed around the motion guide roller 12. As the double glass assembly G enters the guide channel t1, the multiple breaking rods 120 are gradually inserted into the glass B as the motion guide roller 12 rotates and form a driving force to drive the double glass assembly G to transmit backward. Therefore, while forming the motion guide, the glass is pre-broken to facilitate the cutting of the subsequent tool; at the same time, the wear of the tool is reduced and the service life is extended. The motion guide roller 12 extends along the width direction of the double glass assembly G, and the multiple breaking rods 120 are divided into multiple first rod groups and second rod groups that are staggered along the axial direction of the motion guide roller 12, wherein the multiple breaking rods 120 in each first rod group extend obliquely to the left from the roller surface of the motion guide roller 12, and the multiple breaking rods 120 in each second rod group extend obliquely to the right from the roller surface of the motion guide roller 12, and the left and right direction forces formed by squeezing the glass by the multiple first rod groups and the second rod groups and the left and right direction cutting forces formed by the tool on the glass offset each other. When each breaker bar 120 moves to the lowest point, the length of the breaker bar 120 inserted into the glass is 0.4 to 0.7 times the thickness of the glass, and the preferred value is 0.5 times. Considering the unevenness of the double-glass assembly during loading, the setting of the breaker bar in this application satisfies the requirements of motion guidance and pre-breaking of the glass while avoiding accidental damage to the battery cell. In some specific embodiments, elastic members are provided at both ends of the motion guide roller 12, and the elastic members drive the motion guide roller 12 to maintain a downward movement trend.

[0047] In this example, the flattening module 13 is recessed from the rear end to the front and forms an avoidance gap k. Here, the glass is removed while the battery cell is moved out of the flattening channel, which not only prevents broken glass from falling into the flattening channel and causing material jamming, but also facilitates online quality inspection of the glass removal effect during production and subsequent maintenance.

[0048] In this example, the tool 20 includes a plurality of disc-shaped cutter heads 200 horizontally arranged above the conveyor belt 11, wherein the cutter head 200 is a grinding disc or a saw disc, that is, the glass is cut and removed by grinding or sawing, and the cutting surfaces formed circumferentially by the plurality of cutter heads 200 constitute a cutting area; there are a plurality of avoidance notches k and they are arranged one-to-one corresponding to the plurality of cutter heads 200.

[0049] In order to further facilitate implementation, multiple blade heads 200 are divided into multiple blade head groups arranged along the front-to-back direction, wherein multiple blade heads 200 in each blade head group are arranged side by side and spaced apart from each other, and blade heads 200 in adjacent blade head groups are arranged in a front-to-back staggered manner; the number of blade heads 200 in multiple blade head groups decreases step by step from front to back; in the orthographic projection on the horizontal plane, each avoidance gap k is in an arc shape concentric with the corresponding blade head 200; in the orthographic projection in the left-right direction, each blade head 200 in adjacent blade head groups is arranged to partially overlap; in the orthographic projection in the front-to-back direction, each blade head 200 in adjacent blade head groups is arranged to partially overlap. Here, based on the layout of the blade heads of the present application, the glass layer can be completely removed with a small number of blade heads, and the structure is simple, which is easy to install and implement.

[0050] In some specific embodiments, ten cutter heads 200 are provided and divided into two cutter head groups, wherein the front cutter head group has five cutter heads 200, and the rear cutter head group has five cutter heads 200, and the two groups of cutter heads are staggered in the front-to-back direction.

[0051] There are ten rotary drivers 21 and they are connected to ten cutter heads 200. The rotary drivers 21 are conventional drive motors used to drive the corresponding cutter heads 200 to rotate around the vertical direction. In each cutter head group, the rotation direction of a part of the cutter heads 200 is opposite to the rotation direction of another part of the cutter heads 200. In other words, in each cutter head group, there are cutter heads with two rotation directions at the same time. In this way, the lateral force formed by the cutter heads on the glass can be offset, and the probability of the double-glass assembly shifting to the left and right directions during the front-to-back transmission can be reduced. In this embodiment, the rotation directions of the five cutter heads 200 in the front cutter head group are forward, reverse, forward, reverse, and forward from left to right, respectively. The rotation directions of the two cutter heads 200 in the rear cutter head group are reverse, forward, reverse, forward, and reverse from left to right.

[0052] There are ten lifting drivers 22 and they are connected to the ten rotating drivers 21 , wherein each lifting driver 22 is a conventional lifting driving mechanism, such as a lifting rack, for adjusting the cutting height of the cutter head 200 to meet the thickness requirement of the cut glass layer.

[0053] At the same time, the cutting unit 2 of this embodiment also includes guide rails 23 located on the left and right sides of the frame and extending along the front and rear directions respectively, wherein the cutter head group located in the front is slidably connected to the guide rails 23 through a truss j and can be moved forward and backward, and the cutter head group located in the rear is fixedly connected to the frame 10 through the truss j to facilitate maintenance of the equipment.

[0054] In this example, the collecting unit 3 has a negative pressure port d arranged above the material guiding channel t3 and forming a negative pressure area capable of covering the material guiding channel t3, and the broken glass is sucked into the negative pressure port under negative pressure and collected.

[0055] In some specific embodiments, the collection unit 3 includes a collection box 30 and a negative pressure pipe 31 connected to the collection box 30, wherein the negative pressure pipe 31 has a negative pressure port d arranged near the material guide channel t3, and the broken glass is sucked into the collection box through the negative pressure pipe 31 and collected in the collection box; there are multiple negative pressure ports d and they are correspondingly arranged between every two adjacent blade heads 200.

[0056] In summary, after adopting the single-layer glass removal device, the double-glass component is placed flat on the conveyor belt with the glass to be removed facing upward and transmitted from front to rear, and the double-glass component enters the guide channel formed between the motion guide roller and the conveyor belt, and the guide channel forms a motion guide for the double-glass component in the front-to-back direction; then the double-glass component enters the flattening channel, and the flattening module flattens the double-glass component to ensure the flatness of the double-glass component; finally, the double-glass component enters the cutting area formed by the tool based on the motion guide formed by the motion guide roller and the flattening of the flattening channel, and as the double-glass component is transmitted backward, the broken glass formed by the cutting of the tool moves along the material guide channel, and the broken glass is sucked into the negative pressure port under negative pressure and collected. Therefore, compared with the prior art, the present invention, on the one hand, starts to remove the glass based on motion guidance and flattening of the double-glass component, effectively reducing the probability of deformation and deviation of the battery cell caused by the cutting force, ensuring that the glass is completely removed during stable transmission, and is very suitable for further removal of the front glass of the double-glass component after removing the back glass; on the other hand, through the material guide channel formed between the tool and the pressure plate, it is ensured that the broken glass generated by cutting is in the material guide channel to reduce splashing, thereby improving production safety, and at the same time, the broken glass in the material guide channel is collected under negative pressure to avoid the accumulation of broken glass affecting the continuous cutting of the tool, effectively extending the service life of the tool and improving the glass removal efficiency; thirdly, the present application adopts the method of removing the glass segment by segment, not only in the removal of the initial segment of glass, but also based on motion guidance and flattening to ensure that the battery cell does not deform or deflect, ensuring that the glass can be completely removed; at the same time, in the removal of the rear segment of glass In the fourth aspect, based on the segmented layout of the double-glass component, it is ensured that at least 50% to 80% of the glass can be removed based on motion guidance and flattening, which greatly reduces the probability of deformation and deviation of the battery cell. At the same time, under this layout, the formed glass removal efficiency is good and the removal cost is low; fifthly, while forming the motion guide, the glass is pre-crushed to facilitate the cutting of subsequent tools; at the same time, the wear of the tool is reduced and the service life is extended; sixthly, considering the unevenness of the double-glass component during loading, based on the setting of the breaker rod of the present application, the motion guidance and pre-crushing of the glass are met while avoiding accidental damage to the battery cell; seventhly, in each tool head group, there are tool heads with two rotation directions at the same time.
